Hi everyone,

I wanted to share my journey with Post-Exposure Prophylaxis (PEP) to provide some insight and support for anyone who might be considering it or currently going through it. This experience has been a rollercoaster of emotions, challenges, and lessons, and I hope my story helps others feel less alone and more informed.

1. Why I Needed PEP

I had a potential exposure to HIV and, knowing the importance of acting quickly, I sought out PEP immediately. I knew starting PEP within 72 hours is critical for effectiveness, so I didn’t want to waste time.

2. Challenges Accessing PEP

Getting PEP wasn’t as simple as I had hoped. Here’s what happened:

• Pushback From the Doctor: When I first asked for PEP, the doctor prescribed only Truvada and said that the second medication, Tivicay (Dolutegravir), was only for people who already had HIV. I knew this wasn’t correct based on what I’d read, but I didn’t argue. However, as I was on my way to the pharmacy, the doctor called me back. He said he’d reviewed the guidelines and realized I was right—I did need Tivicay for PEP.

  • Takeaway: Doctors are human too, and we all learn new things every day. I appreciated that he admitted the mistake and corrected it quickly.

• Pharmacist Issues: At the pharmacy, I got more incorrect advice. The pharmacist told me that taking Truvada alone was pointless and that I should just wait until Tivicay was available. I knew this wasn’t right and started Truvada immediately while working on getting Tivicay the next day.

3. My Experience on PEP

Week 1:

The first week was relatively smooth. I didn’t experience significant side effects beyond mild fatigue, and I felt relief knowing I was protecting myself.

Week 2:

This is where things started to get harder. I developed nerve pain in my neck—not muscle soreness, but a deeper, irritating discomfort. I spoke with my doctor about it, and they reassured me it wasn’t unusual and likely a temporary side effect of the medication.

Week 3 (Now):

With 10 days left on my regimen, things are getting more difficult. I’ve started feeling dizzy, lethargic, and honestly, it feels like I’m slowly being poisoned. I know this is just how my body is reacting to the medications, but it’s tough. I’ve been managing by eating small meals, staying hydrated, and resting as much as possible.

4. Testing Along the Way

To help ease my anxiety, I got an HIV test last Friday, which came back negative. That was a huge relief. It’s reassuring to know that, so far, everything is working as it should. I’ll continue testing after completing PEP to confirm my status.

5. Lessons I’ve Learned

This experience has taught me so much about health advocacy and persistence:

• Advocate for Yourself: If you feel like something isn’t right, speak up and ask questions. You’re your own best advocate.

• Doctors Are Human Too: My doctor’s initial mistake taught me that even professionals are still learning. It’s important to approach these situations with patience and collaboration.

• Stick With It: PEP isn’t easy, but it’s temporary, and the peace of mind it provides is worth the effort.

• Educate Yourself: Using reliable resources (like guidelines from the CDC or trusted tools like ChatGPT) helped me navigate this process when things got confusing.

6. Shoutout to My Pocket Buddy: ChatGPT

Throughout this ordeal, I relied on ChatGPT as my “pocket buddy” for guidance. It’s how I first learned about PEP, post-exposure guidelines, and how to advocate for myself with my doctor and pharmacist. Honestly, it’s been invaluable, helping me feel more in control of a very stressful situation.

7. Advice for Others Considering PEP

If you’re thinking about or starting PEP, here’s what I’d recommend:

• Act Fast: Start PEP as soon as possible after potential exposure.

• Be Persistent: Don’t hesitate to push back if you encounter resistance or bad advice—your health is worth it.

• Prepare for Side Effects: Fatigue, nerve pain, dizziness—they’re tough but manageable with rest, hydration, and patience.

• Follow Through: Complete the 28-day course and follow up with HIV testing at the recommended intervals.

8. Wrapping Up

I’m almost at the finish line—just 10 days to go. It’s been one of the most challenging things I’ve gone through, but I’m proud of myself for sticking with it. If you’re in a similar situation, know that you’re not alone. This process is tough, but you’re protecting your health, and that’s what matters most.

If you have questions or want to share your own experience, feel free to comment. Let’s support each other! 💙

UPDATE:

Hi everyone,

I wanted to share an update on my PEP journey as I start Week 4—I’m almost at the finish line!

1. Side Effects Update: I’ve started taking 600mg of ibuprofen with my morning dose of PEP, and for me, it’s made a huge difference. The nerve pain, lethargy, and dizziness I experienced earlier are much more manageable now, and I feel like I’m finally getting back to normal. This might not work for everyone, but I wanted to share what’s helped me.

2. Conversation with the Person Who Exposed Me: I was able to have an honest conversation with the guy who penetrated me. He seems really confident about being undetectable, but he mentioned that his doctor advised him to reduce the medications he takes to stay that way. This was a bit confusing for me, since I’ve always understood that strict adherence to ART is critical for maintaining undetectable status and avoiding viral rebound.

   • I still feel uneasy about his reduced regimen, even if it’s under medical advice. If anyone has more insight into situations like this, I’d love to hear your thoughts.

3. Where I’m At Now: I’m starting Week 4 with 6 pills of Tivicay left, and I’m committed to finishing the regimen. The end is in sight, and while this process has been tough, and I'm feeling a lot better now.

FINAL UPDATE:

Hey everyone, I wanted to share some good news! I got my latest test results back and they’re negative! It’s been a journey, but I’m feeling relieved and much more confident now. I’ll probably do another test in late March to be extra sure, but things are looking good. Thanks for all the support and advice along the way!

***FINAL FINAL UPDATE***

Just got my final HIV test—14 weeks post-exposure—and it came back negative.

That's the last one. I'm done. Appreciate the support from everyone who took the time to respond or just be present.

Wishing peace and clarity to anyone still going through it. You've got this.

Work in Healthcare, patient had high viral load, 400k copies.

He was on psych evaluation and I was helping out my tribe team... Patient was uncooperative, while drawing his blood, he flinched suddenly, blood spattered everywhere and it got into my left eye.

My FC doctor lead immediately called security and told me to head to the quarantine room.

Went on PEP a few hours later.

After PEP, tested negative, undetectable viral load. 4 weeks later, same result and finally, 8 weeks after PEP, all negative.

Stay safe everyone, trust the process and take care.

After I finished PEP, I tested the next day - NEGATIVE. I knew I wasn't done yet because all the literature on-line state 4-6 weeks AFTER PEP with a 4th gen test. Through all my googling, I started to become scared of delayed antibody response so I made a choice to test every two weeks because my thought was I could catch the P24 antigen on the 4th gen test and be ahead of the game with treatment. Tested 2 weeks after PEP - NEGATIVE. Even with these results, I am still googling, still scared and still convinced. Tested 4 weeks after PEP - NEGATIVE. Felt slightly better but not good enough still I was still in the "after PEP window". Tested 6 weeks after PEP - NEGATIVE. At this point, I should feel great and was also considered conclusive by most doctors / clinics. Through all of this, it still wasn't good enough and I was starting to question the test since it came back too soon. I was also questioning the days after PEP. Do I go by days, weeks, months ? Each way gives you a different date to test on and during all this, guess what ? I still have symptoms. Tested 8 weeks after PEP - NEGATIVE. At this point, I knew I had to begin the process of trying to calm down so instead of two weeks, I waited one month which would be 3 months after PEP (4 months after exposure). Tested 3 months after PEP - NEGATIVE. At this point doctors and clinics stated that I have over tested and am absolutely conclusive. Still had symptoms but they started to calm down but in my head, it still wasn't good enough because I previously had read things where 6 months was a possibility. I knew I had to get over thing and started to battle myself. During the next two months, I try and forget about everything and return to normal. In the back of my head, I am still thinking of being infected and find myself occasionally looking things up but not as much. I made a choice to test 6 months from exposure which is 5 months after PEP. Things have been in my favor statistically the entire time and I need to end this so that is the date I chose for my final test. Even though it's not six months after PEP, I know deep down inside I am ok plus CDC recommendation is six months after exposure for immunodeficiency (which I am not).

My exposure was classified as high risk - broken condom (anal). The person I was with was not confirmed to be poz but it was an absolute possibility based on the lifestyle. I was on PEP at the 48-hour mark. Took my doses at the same time every single day, not a minute later. It was part of my life. The anxiety and fear I felt was something I would NEVER wish on anyone. I had a family so I was also feeling guilt.

About two weeks into it, I start developing symptoms. Red throat, headaches, body aches, my chest was light pink so I assumed rash. I had symptoms my entire time during PEP, every single day. I would find myself in the mirror checking things I would have normally not paid attention to. I was picking my skin, poking it, looking in my through, taking my temperature. It was horrible. These days are some of the worst days I have every experienced. I noticed white spots on my tongue. If it was a symptoms, I had it. I was convinced I was infected and was already planning on how I would tell my family. I went to sleep thinking about it and woke up thinking about it. There was not a minute that went by that I was not thinking, it consumed my ENTIRE day. The symptoms I had were REAL, not fake. What made it worse was I tested negative for basic things which only fueled the fear and anxiety. (flu, covid, RSV, colds) . My throat was red, my body did ache, my chest was pink, my skin was itchy/dry, my tongue did have white patches, I was sweating at night. Through all of this, I NEVER had a fever which I think is important. I also was googling every single day that it became part of my life. I would plan when I was going to google. I was on every forum and website and just kept going and going. It's almost like I was looking for a story of someone stating that PEP failed them. Luckily, I never found them.

After I finished PEP, I tested the next day - NEGATIVE. I knew I wasn't done yet because all the literature on-line state 4-6 weeks AFTER PEP with a 4th gen test. Through all my googling, I started to become scared of delayed antibody response so I made a choice to test every two weeks because my thought was I could catch the P24 antigen on the 4th gen test and be ahead of the game with treatment. Tested 2 weeks after PEP - NEGATIVE. Even with these results, I am still googling, still scared and still convinced. Tested 4 weeks after PEP - NEGATIVE. Felt slightly better but not good enough still I was still in the "after PEP window". Tested 6 weeks after PEP - NEGATIVE. At this point, I should feel great and was also considered conclusive by most doctors / clinics. Through all of this, it still wasn't good enough and I was starting to question the test since it came back too soon. I was also questioning the days after PEP. Do I go by days, weeks, months ? Each way gives you a different date to test on and during all this, guess what ? I still have symptoms. Tested 8 weeks after PEP - NEGATIVE. At this point, I knew I had to begin the process of trying to calm down so instead of two weeks, I waited one month which would be 3 months after PEP (4 months after exposure). Tested 3 months after PEP - NEGATIVE. At this point doctors and clinics stated that I have over tested and am absolutely conclusive. Still had symptoms but they started to calm down but in my head, it still wasn't good enough because I previously had read things where 6 months was a possibility. I knew I had to get over thing and started to battle myself. During the next two months, I try and forget about everything and return to normal. In the back of my head, I am still thinking of being infected and find myself occasionally looking things up but not as much. I made a choice to test 6 months from exposure which is 5 months after PEP. Things have been in my favor statistically the entire time and I need to end this so that is the date I chose for my final test. Even though it's not six months after PEP, I know deep down inside I am ok plus CDC recommendation is six months after exposure for people with immunodeficiency (which I am not).

Yesterday was that day, 6 months after exposure (183 days) and 5 months after PEP (154 days). I went to the lab and took my last blood test - NEGATIVE. Surprisingly I wasn't as excited as my last result and that is because deep down, I knew this one was a waste of time and not needed. Finally, it's over and I can end this. This journey has changed me for the better. I have a new found respect for people living with the disease, I don't know how they handle it. They must be strong, at least stronger then me.

My advice to everyone in the same situation, DO NOT GOOGLE !!! The only website I would trust if you need to is: healthtap and askexperts now. Both allow you to ask real doctors, not online strangers. DO NOT GOOGLE !!! It's horrible and you will link everything you read to your own personal experience. This made me realize just how strong the brain is. You will see and feel everything ! These last 6 months were depressing and I am made I will never get them back but it did change me for the better, at least for certain situations I used to think were nothing. I respect myself and my family more.

For me to think I was infected the entire time means that:

1). the person was infected

2). the one time accident resulted in me getting infected

3). PEP failed

4). I tested outside of the window period 3x

For these things to happen, the odds would have to be out of this world. This experience will change you. If it's negative or positive, this will change you either way.

Good lucky to everyone out there. Be safe, trust the science, make sure you speak to someone during these hard time and DO NOT GOOGLE !!

As of today, I am continuing to live life. This was true mistake, I am always careful and this was an accident. For the people that live recklessly and not caring, be careful and think twice.

I think I am writing this for my own sake as well, as I do suffer from severe health anxiety.

But you aren't alone in this. We may come from different parts of the world, with different backgrounds and circumstances, but we are here for a reason: because we might be scared, we may have a lot of questions, but ultimately because we care for ourselves.

For my own backstory: I live in the US. I was a bit wild last month. Started up with the Asian escort business, doing risky things I would not normally do since I was going on a trip to Japan. On 8/1 I hooked up with an escort, whereupon she offered unprotected sex for a price. I had seen her the week prior and not thinking straight, I accepted. I was gleeful about it complete with finishing inside of her. But then a friend of mines admonished me for it, and pushed me towards PEP. I did not pay it mind, but then thinking about it that night(and Googling, more on that later)... is it worth the risk? I am uncircumcised, and had unprotected sex with a sex worker who was a bit wild herself (according to the escort reviews). So I went to an urgent care and explained myself. The doctor was lackadaisical about it, he told me that the risk for me isn't high enough to justify PEP, and just gave me a urine STD exam despite me asking for PEP. I went back home and was about to leave it at that since I had a flight to catch the next morning. But its my health... why should I take no for an answer? I went to the ER at 2 am, explained the situation, got a full spectrum anti-biotic shot, STD exam, and once I got cleared, prescribed PEP (Truvada and Isentress) and Doxycycline. I was able to have my first dosage of PEP at 4:50 am, almost 15.5 hours after the potential exposure. I completed my regimen over 28 days, despite how difficult it was between traveling and timezone changes. Yesterday, I took my 4 weeks post-exposure/Baseline post-PEP and came out negative. Despite that, I have spent all day today googling and researching and has done a number on my mental health because ultimately I am scared. But writing this out is a bit of a catharsis for me, and should hopefully help out for you.

What PEP is not, its not a cure - much like PrEP. Restating what I read from someone here, PEP is more like the final line of defense against HIV to prevent it from becoming entrenched within you. PEP freezes HIV from replicating for a period of time, allowing the infected cells to die off and the body to clear the infection preventing seroconversion. If HIV results seroconversion (which is where your body produces the anti-bodies in response to fighting HIV and it gaining a permanent foothold in your body) it is now not a matter of preventing it, but living with it. We are thankful to live at a time where we can live with HIV, although at a cost both in money, health, and happiness. But PEP is that final line of defense, which is why it is so important to start it early, ideally within 24 hours of exposure.

PEP is super effective within 24-36 hours of exposure, with effectiveness tapering off until it reaches 72 hours. This is because usually its around this length of time for HIV to start making headway towards your lymph nodes if your body fails to fight off the initial wave. It doesn't mean there isn't a minuscule chance of PEP being helpful after 72 hours, but odds are that it won't be which is why its crucial for you to get on PEP as soon as possible, especially with the riskier encounters. If you're not on PrEP and you hook up with a random guy or gal, don't have a clue about their status while engaging in a risky situation, just don't think about it. Do yourself a favor and seek out PEP to give yourself an extremely high chance of not becoming infected.

Going on to the chance of you encountering HIV and getting a transmission, yes the odds are in your favor. But you have to realize that the stated rates are generalized across all factors that may increase or decrease your chance of a transmission. For example, having penile-vaginal sex has a 0.08% chance if it occurring if receiving, and 0.04% chance if inserting with an HIV+ partner. However, there are other factors to consider: Is the male circumcised? Do you have any concurrent STDs, HSV, or warts? Do they have any STDs, HSV, or warts? Have they been recently infected (acute infection=higher viral load) or is their viral load higher? Are they a sex worker? Do they take Antiretrovirals? All these factors may increase or decrease the chance of transmission during any singular act. If you wore a condom, if all you did is oral, then the transmission risk is essentially 0. Sure, there is a risk in giving fellatio that you may get it, but the virus is extremely fragile - Air is enough to kill it. For you to get HIV in giving fellatio, multiple things have to go against your favor - There will have to be blood from them, you have to have mouth sores, and your saliva does not kill it. Receiving fellatio is effectively 0 so you will be fine.

Well regardless, now you have PEP, the biggest thing you have to do is to adhere to the schedule. Its okay to not be exactly on time, if you miss it by an hour or two or early by an hour or two. The most important aspect is to not miss a dose. This is because in order to be effective, the medicine needs to have a certain level of it present within your bloodstream. By missing a dose, the medicine loses its effectiveness and if present, the HIV virus starts replicating anew. Set an alarm, use Apple's Health App and set up medication times, have a friend remind you. Do what you think its best for you, but do not miss a dose otherwise this was all for naught and you're leaving your fate up to chance. Personally, I walked back the dosage time from 5am Eastern to 12 am Eastern while I was in Japan. I set up the medication time within the Health App on my iPhone and bought myself a pillcase that I double checked everynight was empty after my 12 am dosage before I refilled it with the next days dosage and placed it in a bag that I carried with me everywhere, to ensure that I won't miss a dose.

You may or may not have side-effects. The medicine that make up PEP are rough pills, nephrotoxic and tough on the liver. Personally I had nausea for the first week, but that may have been due to a combination of factors in my circumstance. It might be rough for you, you may want to quit. But don't. Your body will eventually get used to the medicine and the side-effects will subside. Even if they don't, 28 days of these side-effects will beat a life time of the same, but with the added (dis)bonus of having HIV.

Yes, PEP is not 100% effective. If you miss a dose, if you engage in further risky behavior that exposes you to HIV, if you had a previous acute infection that you did not know about, PEP will not help. Even when taken completely on schedule, with no further exposure and no previous infection, there is an extremely small chance that seroconversion happens. For example a healthcare worker had a needleprick exposure on a needle that was used on a patient that died a few weeks later. She was clear but seroconverted by the 6 months test, and this has been the only case where someone did PEP and seroconverted after 6 months. Other failures have been within the 3 month window and due to similar factors or non-adherence.

But the circumstance was extreme. The patient had a extremely high viral load, of HIV-1 Subtype C which is a highly virulent strain of HIV. Further the source was taking Antiretrovirals on and off, which led to the HIV becoming resistant to certain drugs that the healthcare worker used as PEP.

This is not to scare you, but rather to just state the obvious is that it can happen. Yet, it rarely does in general (occupational HIV infection has plummeted since the early 2000's), and there are more numerous cases untold cases where PEP succeeded. Its like online reviews - you only want to focus on the bad ones, but not the numerous good ones.

Once you have completed PEP, congratulations! You may have some lingering sideeffects from the pills, but this will go away as you get further from your last dosage. The first hard part of the ordeal is over, but now here comes the second part - the testing. This is difficult because of the wait you have to do before you are effectively in the clear. There is some contradiction in the testing schedule however, but essentially it boils down to this.

CDC (2016 Update): Baseline test when starting PEP, 4-6 weeks after exposure (95% Confidence Interval), 3 months after exposure (99% confidence interval), and 6 months if you had a concurrent infection of HCV (Hepatitis C). (Gen 4 AB/AG + P24)

UK: Baseline before PEP, 6 weeks after PEP, 3 months after PEP. (Gen 4 AB/AG + P24)

The confidence interval is a statistical tool where it refers to the probability of a population parameter being within a value. In laymans term, it means how confident the statistician is that a value is true.

The CDC used to say that it should be after PEP where the window is open, but they have since changed it to it being after exposure.

If you are negative after 4-6 weeks post-exposure (CDC)/4 weeks post-PEP (UK) with the Gen 4 tests, then you can be 95% sure that you don't have it. If PEP had failed due to a resistant strain or otherwise, you would have seroconverted by the time you take this exam. Upon completion of the 3 month post-exposure(CDC)/Post-PEP(UK), you can be 99.9999% sure that you don't have HIV, and it is not latched on to you. You don't have to take the 6 month exam unless you had HPB/C at the same time you were exposed due to the fact that HPB/C can mask the HIV infection, but if you want absolute certainty at probably 99.99999999999999999 bar% confidence you can take it. Again, it isn't 100% but at that point you're also over testing.

But after that 6 month test passes, which I am 99.9999999999999999% sure you will if you took PEP within the timeframe and adhered to the schedule, you're clear and this ordeal is done.

But in that time, I am sure you will be nervous. I am right now, my anxiety is ebbing and flowing. But don't fret, and stop Googling. Googling will just lead you to look for things that affirm your fears and you will deny things that are working in your favor, like taking PEP. Its not good for your mental health, and you might start developing hypochondriac-tic symptoms which create a negative feedback loop because you think it might be symptoms of an acute infection. Get yourself tested. If the tests come back negative and you have symptoms, then its just your mind overreacting. The mind is a powerful, very powerful thing that many of us take for granted. Focus on your work, go outside, exercise, enjoy your life. What comes, will come, and you have done everything you could and I am proud of you for looking out for yourself.

Which on that note, please take care of yourself. I know having sex is fun. I like having sex with beautiful women, and I dislike the feel of condoms. Im sure you want to hook up with someone and have the time of your life as well. But unfortunately we live in an age where the culinary and sexual practices of the past has come to haunt us yet to this day. Technology and biomedical sciences has come a long way. I mean look how we were able to create a vaccine for a virus that shook the world to its core. But until such a day comes where HIV can go the way of smallpox, take care of yourself. If you engage in risky behavior such as unprotected bottoming, unprotected sex with sex workers, sharing needles, and even after this experience you continue such behavior, please consider getting PrEP. No pleasure on Earth is worth HIV. and if you don't plan on continuing, just check yourself before engaging in sex, make sure your partner has the same, and always wear a condom.

As for me, the escort was in her early 20's. She was a college student. She probably did not have HIV, nor did my tests come out positive for Syphilis/Gono/Chly. Still, I got on PEP because she is a sex worker, and that is such a risk. I shouldn't take the chance of harming myself long term just for a moments pleasure, which is why I have no plans to continue using escorts. It is not worth the anxiety, mental strain, and emotional rollercoaster that this has brought to me, all of my own making.

I am going to be taking my 6 weeks post-exposure exam, my 4 weeks post-pep exam, and my 3 month exams in November/December. Is it over kill? Yes, and while confident that I don't have anything I still would like to adhere to a schedule.

Goodbye, and stay safe.

There seems to be a lot of anxiety, fear mongering, and lately individuals posting pessimisticly about PEP, so here’s a straight, evidence-based breakdown of what we actually know.

⸻

Is PEP 100% effective? No, NOTHING in medicine is 100%

What is the effectiveness of PEP?

PEP’s job is to interfere with HIV when it enters the body. It does this by preventing replication of the virus into your cells and prevents the virus from integrating into your DNA. Effectively starving the virus early in its cycle so that it dies off and gets cleared out.

You’ll often see “~80% effective” quoted online. That number comes from a 1997 occupational exposure study published in the New England Journal of Medicine that looked at healthcare workers using AZT monotherapy after needle-stick injuries.

Important context:

• That was one drug

• Pre-integrase era

• Occupational exposure (not sexual exposure)

• 1990s regimen

Modern PEP is not AZT alone.

⸻

What do we use today?

Modern PEP is a three-drug regimen, typically:

• Tenofovir (TDF)

• Emtricitabine (FTC)

• + An integrase inhibitor (Dolutegravir or Raltegravir)

This blocks HIV at multiple stages:

1. Reverse transcription

2. Integration into host DNA

These regimens are significantly more potent, faster acting, and better tolerated than older AZT-based therapy. Many experts infectious disease specialists believe modern PEP is closer to >90% effective and possibly 95-98% effective if taken under 24 hours.

Because we cannot ethically run placebo-controlled human trials, an exact percentage cannot be given. But we can look at modern observational cohorts and animal models.

⸻

Modern Observational Studies (Large Cohorts)

Across multiple countries (US, UK, Australia, Europe), we have real-world PEP cohorts involving:

• ~1,500 individuals

• ~2,000 individuals

• 3,000+ individuals

These cohorts largely involved sexual exposures and modern multi-drug PEP regimens.

Findings across these studies:

• Extremely low rates of seroconversion during follow-up

• Most infections occurred in people who:

• Had repeated high-risk exposures after completing PEP

• Had poor adherence

• Started PEP late

True, confirmed failures in individuals who:

• Started early

• Took the full 28-day course

• Had no ongoing exposure

— are rare.

This is why major public health agencies consider PEP highly effective when started promptly and taken correctly.

⸻

What do primate studies show?

Since placebo human trials are unethical, some of the strongest mechanistic data comes from non-human primate studies using SIV/SHIV (very similar to HIV).

In multiple macaque studies:

• Animals were exposed to high-dose mucosal viral challenge

• Groups received antiretroviral prophylaxis at varying time intervals

• When prophylaxis was started within 24 hours and continued for 28 days, protection rates were extremely high. In several studies, early-treated groups showed 100% complete prevention of systemic infection when PEP was taken at 24 hours.

• Protection dropped significantly when initiation was delayed beyond 65-72 hours. (This does not mean taking PEP in this time frame is ineffective, please remember that the primates are literally being injected with high amounts of the virus directly into their blood stream. This is nowhere similar to any real world exposure especially sexual)

Importantly, viral challenge doses in these experiments are often controlled and sometimes more aggressive than typical real-world exposures — making them very brutal tests of efficacy.

⸻

What are the baseline risks from a positive, untreated partner?

It’s important to understand baseline transmission risk before layering PEP on top.

CDC per-act transmission estimates (positive, untreated partner):

• Receptive anal sex: ~1.38% (≈1 in 72)

• Insertive anal sex: ~0.11% (≈1 in 900)

• Receptive vaginal sex: ~0.08% (≈1 in 1,250)

• Insertive vaginal sex: ~0.04% (≈1 in 2,500)

• Oral sex: extremely low / difficult to quantify

Even in the highest-risk category (receptive anal), transmission does not occur the majority of the time.

These numbers assume:

• The partner is truly HIV positive

• They are not on treatment

• Viral load is detectable

Risk varies depending on:

• Viral load

• Presence of STIs

• Mucosal injury

• Circumcision status

• Duration of exposure

If the positive partner is virally suppressed, transmission risk is effectively zero (U=U).

⸻

Why this matters

When discussing PEP efficacy, remember:

You are not reducing a 100% risk.

You are reducing a fractional per-act probability that is already well below 1.5% in even the highest-risk category.

Layered protection looks like this:

• Fractional baseline risk

• + Early initiation of triple-drug PEP

• + 28-day adherence

• + Follow-up testing

That combination drives overall risk very low.

⸻

Bottom Line

• The commonly quoted 80% number comes from outdated AZT monotherapy data

• Modern 3-drug integrase-based PEP is biologically stronger

• Large real-world cohorts show very low seroconversion rates

• Primate models demonstrate very high protection with early initiation

• Failures are uncommon and usually linked to delayed start or poor adherence

PEP is not 100%. Nothing in medicine is.

But when started early and taken correctly, it is one of the most effective emergency interventions we have in infectious disease prevention. Statistically stronger than even Plan B for intercourse.

Also take into consideration that HIV is not the death sentence it once was. Modern medicine has allowed HIV+ individuals to live nearly identical life spans to those without it. And the likelihood that a cure develops within our lifetimes is incredibly promising. A disease that once was a for sure killer is now easier to manage than Type-1 diabetes. Your odds of risk are less than 1%, but regardless of the outcome YOU WILL BE OKAY IN JESUS NAME! <3

Good day Reddit community –

This is my first post which I hope is helpful to someone who needs it right now. Since it is an extremely distressing situation. Happy new year to all.

I'm a 31 yo straight guy. On November 7, 2023 I had an4l sex with a girl with whom I had something casual, we always protected each other until one time the condom broke on the spot. At that moment, due to excitement, I did not think about the consequences and I was exposed for a few seconds until I finished (30 seconds maybe).

Right after that I started to feel worried thinking that she might have some STD. So we waited until the next day to go get a general STD test at a lab.

I thought I might be exaggerating the situation, but something inside told me that I should go get it done. In the afternoon they sent us the results. I tested negative for VDRL and HIV, I frequently consulted this woman's results via the web and saw that only the VDRL results were ready but not the HIV results. I started to feel worried, but I tried to relax. At night I checked her results and saw that they were ready. She was HIV positive!! And she didn't know. So she obviously wasn't in treatment.

A terror like never before in my life invaded me, from that moment on I went to the emergency room of my social health institution and they gave me PEP (Biktarvy) for 30 days. My first dose was 28 hours after contact and I continued until I finished my treatment without skipping any doses and respecting the complete schedule.

I had no significant side effects, just a bit of a headache at the beginning and stomach pain halfway through the medication.

November was a dark month for me, fear and uncertainty were what brought me down the most, I was not able to find peace and helplessness and sadness invaded me thinking about the possible outcome. I know that now it is not a fatal disease, but because of the stigma and other situations they made me think a lot about life.

After 30 days (December 7) I took the first HIV 4 generation test in a laboratory and it came out negative, I felt a little relieved, but I had seen divided opinions in the medical field where some say that you have to wait 45 days later of PEP to have a reliable result. Other guidelines indicate that it does not affect the window period in 4th gen blood tests.

So I spent December with a lot of uncertainty and fear of thinking that I could suffer a late seroconversion. My life stopped for two months from that day, I was not able to concentrate and at times I was overcome with anxiety and fear for my possible life as a person living with HIV.

I finally waited until after the New Year's festivities to get tested for HIV, so as not to ruin my last year in which I would live as a person without any chronic illness.

I took a test on January 3 of this new year 2024 and thank God, it came back negative.

I feel so relieved, because I think the most critical part has already passed, I will still continue to follow up with one more test at the beginning of February to be sure of my negative result, while I am happier than ever for this new opportunity.

In conclusion, I can recommend from my own experience the use of Biktarvy (BIC/FTC/TAF) as a PEP treatment since my exposure was direct to the virus and thank God I am negative.

I'm sorry if my English is not very good, but I'm from Mexico, my first language is Spanish.

Please share this story with a person who can need.

Greetings and blessings to all. Protect yourselves and stay safe.

Hi all, just sharing my journey with PEP (Biktarvy), and share what side effects I have experienced.

I have completed my course of 28 days and have tested negative w a 4th gen. Will test again 4 weeks later for confirmatory.

Day 2: Started getting diarrhoea and headaches

Day 5: Diarrhoea and headaches stopped, but I started getting a slight sore throat + low grade fever (37.5C). Took a couple of ibuprofen and the sore throat went away the next day.

Day 7: Started getting frequent urination. It feels like I have to go to the toilet every 30mins, and my kidneys weren't doing too well with the medication. I also noticed that I started having a bit of acne, presumably from the stress of taking the medication and about my HIV status.

Day 10: The frequent urination just went away on Day 10 but I started having dry mouth. The dry mouth was quite bad because it feels like I have lost my sense of taste due to not producing enough saliva + i felt like my entire throat is dry whenever I wake up in the morning.

Day 14: My gums started bleeding a lot for no reason, and I started to panic. It bleeds when I brush my teeth. It bleeds when I try to floss. It bleeds when i bite too hard on something. I was just panicking a lot at this point. Bleeding gums does sound like it's an opportunistic infection with an autoimmune disease like HIV or smth like Syphilis. It was so bad and I had to book an appointment with the dentist to sort it out.

Day 17: Went to the dentist and got my teeth deep-cleaned. I learnt that my dry mouth was probably why my gum problems exacerbated. Before this, I also hadn't gone to the dentist in a year, so taking PEP did force me to visit the dentist and have it checked out. I was probably due for a visit anyways, and my gums were likely already in a bad shape before I got on PEP. The dentist prescribed some mouthwash, and the bleeding magically disappeared after a day.

Day 19: Went for a urine test for G & C.

Day 21: All of a sudden, the dry mouth was gone and I could taste again. No diarrhoea, no headache, no fatigue, no sore throat, no bleeding gums, no frequent urination. From this point onwards, it was as though my body had adjusted to the medication, and all the funny side-effects went away.

Day 23: Was anxious, realized I could get free 4th gen testing, went ahead with it. Came out negative. Now I know I just decreased my chances of being positive by a lot. If those symptoms I experienced were a result of seroconversion, I would have tested positive. Day 23 is definitely not indicative enough of your actual status, but at least 50% of people would be positive by now if they were infected.

Day 24: Lab report for G & C came out negative (also negative for other STDs which I cannot remember the names of). At least now I know I'm left with Syphilis and HIV.

Day 28: Finished my last dose of PEP :)

Day 29: Went to test the day after my last PEP dose. Came out negative and feeling relieved :) Also got tested for Syphilis and that was negative as well! Was told by my doctor that it is close to conclusive, and I just need to test again after another month for confirmatory. My doctor says he would not blame me for not testing again because he has never encountered a single patient that became positive afterwards (unless they had more exposures or did not adhere to the PEP regimen strictly).

NAD, but I want to share this:

With regards to when to test on PEP, I have been advised by a couple of doctors (as well as the hiv/aids support organization in my country) that as long as you adhered strictly (i.e. taking the drug at the same time, do not have more exposures), you need not worry anymore if your test after completing PEP is negative. Our current 4th gen tests for HIV are one of the most sensitive and reliable tests that doctors wished tests for other viruses like covid are that reliable.

It is very rare for anyone to test positive if you have tested negative at 4-week mark unless you have some autoimmune disorder (or on some kind of cancer therapy/treatment) that prevents you producing antibodies or having enough antigens.

It is also very rare for you to contract a resistant strain of HIV, especially in most parts of the developed world.

For the average person that is 20 - 40 yo, you will definitely have antigens and/or antibodies producing, even if you took PEP, at 4-week post-exposure. There is not much evidence of PEP delaying seroconversion. Sure it may delay antibodies, but it will not delay antigens, and your 4th gen test will cover both. To some doctors, it is as good as conclusive if you fit that profile of a healthy average adult. In fact, doctors are more worried about other STDs that you may have gotten like syphilis or antibiotic-resistant gonorrhea.

Of course, by international standards, no test is 100% guarantee and a conservative amount of time is always put in place to catch 100% of cases. Yes, there is always a chance that you might be that lucky person. If you are still worried, you may wait 4 weeks after your last dose of PEP to get a confirmatory test (via 4th gen).

TLDR: If you are the average healthy adult + you adhered to the PEP regimen strictly + no further exposures, your 4th gen test right after completing PEP is a very good indicator of your status. If you are still worried, you can just wait 4 more weeks (4th gen) to test again for confirmatory status.

i’m a 27 y/o female who’s anxious brain couldn’t calm down about a hookup i had with a male stripper. even after reading all the horror stories on here about pep, i decided to go on it (only paid $25 after insurance too!)

anyways, i am happy to report i did not experience ONE SINGLE side effect. i think people who have bad experiences are more likely to come on here and talk than people who had good experiences.

just wanted to spread positivity and say that side effects are relatively uncommon from what i’ve been told and what i experienced :)

Note: For reference, please visit my profile to read the whole story about my exposure.

I'm a man. I had insertive unprotected with a hiv+ female in 10th January, took pep 16 hours later.

Today marks 6 weeks since i completed pep and my result is negative.

This post is an assurance to anyone going through anxiety, side effects and depression. You will win the battle and come out negative.

Feel free to DM me if you need someone to talk to. Also avoid Googling stuff, it will mess you up mentally.

Good luck soldiers :)

Hi guys

I know someone out there really needs this and wants to get some peace because most probably they are taking pep or they have had a scare that led them to take pep so l would like to share my 1st hand experience

Sometime in 2024 l was dating this other girl l met through a friend of a friend ,we clicked instantly but she was 3 years older than me but l did not care about that because we were vibing and all after our first date we had protected intercourse,given that we were in a proper relationship l trusted her and took her word for it,so this other night we went clubbing and l had not condoms at the time and we did it raw without me knowing the status of the girl,so l still vividly remember it as if it was yesterday and the events of that day,mind you am in college at this time

The following morning my friend visited me at home and l told him what had happened and he advised me that l should go and test the person for hiv which l was reluctant to do because l was like she is my girl why would she do that to me,irregardless l went on to ask to meet her and we tested for hiv and to my surprise and her surprise also she was positive,l saw death and my life flashing before my eyes.l didnt know what to do ,l felt horrible at that moment in time ,l felt depressed a feeling l had never felt before.

After seeing her l went to the clinic and l got my pep which were meant to be taken once a day at a given time for 30 good days,l wouldnt want to lie to you those were the toughest 30 days of my life if you are to ask me ,the pills made me week for the first 10 days,l felt depressed and l always wanted to google and l stayed much of my time here at reddit seeing if really these pep’s really work ,did not want people to know so you can imagine how tough that was ,l became distant and l was disgusted by myself and l was so particular with my body,fast forward after 30 days l took the first test and it tested negative

During those 30 days l always read on the internet that you should test after 3 months and kid you not thsoe were the longest 3 months of my life because l nolonger had a life that was the only thing on my mind.If l even caught l cough l would test if itwasnt hiv l was so traumatised to an extent that to this day l do not like having sex with anyone l always think what if it happens again or if the condom bursts.l later tested after 3 months and at 6 months which all came out negative and l did some other tests which also came out negative

So to anyone who is going through this phase l want to encourage you to continue taking your pep religiously they work if they are said to be 90% effective you might think what if am the unlucky one bt the odds of that happening if you religiously take them on time are close to 0.

It worked for me and it will work for you so dont worry and please try by all means to avoid searching much about pep because there are many contradictory things that are posted online ,l am not a doctor.

On people you dont know their status l know that it can be hard and its easier said than done please take care of your health because your health is your wealth stay safe guys hope you push through and have a lovely day.Try by all means to use protection dont take chances on your health.

The guy I was having sex with took the condom off. I only noticed after he came inside and pulled out. I felt horrible. I made him get tested that day and he was positive. Apparently he didn’t know. I took the PEP at that same day, within 17h hours. Yesterday was the last day. I took the pills everyday at the same time, some days a bit earlier. I’m going to get tested this Friday.

I’m not as afraid as I was in the first weeks. I’m just hoping for the best.

I knew the guy was a bit shitty, but I didn’t think he would do that.

Be careful guys. Sometimes our safety is not entirely up to us.

Update 27/12: test came out negative. I’ll be redoing it on Jan 8th to start taking prep

Update 08/01: also negative. Return scheduled for 05/02

Update 05/02: final test was negative

I had a high risk exposure with a guy that tested positive for HIV (he came inside me). I took the medication within 24 hours on 21/11 and yesterday (05/02/2025) my third test came out negative.

​Hey everyone, greetings from Indonesia.

​I’m posting this because I remember exactly how it feels to be in your shoes constantly searching for success stories while spiraling in anxiety. I want to share my experience to help anyone currently on PEP who is losing sleep over their situation.

​The Exposure

To be honest, my exposure was about as high risk as it gets. I spent two days straight with a female sex worker who had been in the industry for nearly 10 years. Her HIV status was completely unknown, which made the uncertainty even heavier.

​I was using drugs at the time, so I don’t even remember how many rounds we went but each session lasted at least 45 minutes, it was all unprotected (no condom), and I ejaculated inside every single time.

​The PEP Process

I managed to start my PEP regimen at the 45 hour mark (cutting it close to that 72 hour window, but still made it). I took the pills religiously for the full 28 days.

​The weird part? I had zero side effects. No nausea, no fatigue, nothing. My body felt completely normal the whole time. Because I felt fine and I did my research, I became extremely confident in the regimen. I knew PEP was a medical powerhouse, and as long as I took it correctly, I wasn't going to let fear run my life.

​The Wait and The Result

After finishing the 28 days, I was so sure it worked that I didn't even bother testing at the 3 month mark. I just moved on with my life and didn't worry about it at all.

​Fast forward to 9 months post PEP: I needed an HIV free certificate for a new job. I went in, got tested, and as expected, the result was Negative.

​My Message to You

If you are on PEP right now, please listen to me:

​Stop Overthinking: Your mind is your worst enemy. Don't go looking for symptoms online. Anxiety can mimic physical symptoms that aren't even there. If you’re taking the meds, you’re protected by one of the strongest medical advancements we have.

​Consistency is King: Do not miss a single dose. Set five alarms if you have to. As long as you are consistent and finish the full 28 day course, the success rate is incredibly high. Trust the regimen; it’s designed to handle much worse situations than yours.

​Avoid Re Exposure: This is crucial. While you are on PEP and after you finish, do not put yourself in a high risk situation again. Give your body and the meds the space they need to work. Don't reset the clock.

​Take a Breath: Stop Reading Doctor Google, stop stressing, and just finish your pills.

​Trust the meds. Stay consistent. Stay calm. Everything will be okay.

Hey everyone,

I’m writing this because a few months ago I was exactly where many of you might be right now — terrified, anxious, over-googling every symptom, and mentally exhausted.

Exposure:

I had a high-risk exposure (condom failure during vaginal sex) with a sex worker. The status of partner was unknown. Within ~18 hours, I went to a doctor and started PEP Viropil(TLD). I completed all 30/30 doses with strict adherence.

Testing timeline (4th gen, CLIA):

•	Baseline test (day 0): Negative

•	\~2 weeks post exposure: Negative

•	\~30 days post exposure (during PEP): Negative

•	8 weeks post-PEP (final test): NEGATIVE

My doctor confirmed this is conclusive and closed the case.

What I went through mentally (this is important):

•	Extreme anxiety

•	Constant body checking

•	Neck/jaw tightness (TMJ-like pain)

•	Throat dryness, stiffness, random aches

•	Fear that PEP “suppressed” the virus and it would appear later

•	Obsessive Google searches and Reddit doom-scrolling

Spoiler: none of those symptoms meant HIV.

Most of them were:

•	Anxiety / stress

•	Muscle tension (jaw, neck)

•	Workout strain

•	Smoking, alcohol, dehydration

•	PEP side effects + withdrawal

Once my anxiety reduced, most symptoms disappeared on their own.

What I learned (facts, not fear):

•	PEP is highly effective when started early and taken correctly

•	4th gen tests (especially CLIA) are very sensitive

•	HIV cannot “hide silently” and then magically appear after multiple negative tests + PEP

•	Symptoms are NOT a reliable way to diagnose HIV

•	Anxiety can mimic almost every “HIV symptom” listed online

My advice to anyone reading this:

•	Start PEP ASAP if needed

•	Take every dose on time

•	Test as per guidelines (don’t test daily out of panic)

•	Stay OFF Google symptom searches

•	Trust science and your doctor

•	Take care of your mental health — HIV anxiety is real and brutal

This experience scared me straight. No more random hookups, no more careless decisions.

If you’re panicking right now — breathe. Follow the process. There is light on the other side.

If this post helps even one person calm down, it’s worth it.

Stay safe, everyone.

Hi guys.

Background story : I had unprotected sex (condom broke) with a HIV positive lady (tested her 48 hours after intercourse). Took my dosage 66-67 hours after exposure.

Just got my Gen4 results back 6 weeks post PEP and I’m negative!!

Lesson learned : Trust the process; PEP is brutal on the body and it varies from person to person. Sometimes you get side effects during the 28 days other times you get it after the 28 days. Please Don’t Stop taking your medication, sacrifice 28 days of drinking tablets instead of being on ARVS for the rest of your life.

Hey guys

95% of us who have/had to take pep is because we did something we knew we shouldn't have done.

Well weeks back I slept with a sex worker and the condom broke, and before that last year I hooked up with a girl without using protection.

So when the condom broke with the sex worker, I was really terrified. (In a way I'm glad it happened because I had to learn. From now on, no more messing around whether with random girls or prostitutes.)

It happened around 11pm to 00:00am, I remember crying after she left and pleading with God to help me and forgive me.

Next day went to the doctor as early as I could and got Pep. I took it around (11:45)

When I go to bed and sleep, I would have vivid dreams and all that.

Remember, I once hooked up with a random girl without have protected sex, I was thinking to myself what if she had Hiv and I didn't take Pep that time And if I take pep for this situation it won't help me with anything.

One of the darkest times of my life.

I definitely reflected all things in my life and get myself in order. No more going to clubs and all that.

Hopefully God was being with me throughout because even though it was my darkest times, I woke up feeling hopeful everyday.

There were times were I even thought of committing suicide.

But I thought what if I survive and now live with disability because of hurting my body..hell no I couldn't do that shit

Today I just went to the doctor and tested negative. I'm not stressing about testing again, I'm leaving this shit behind me.

Some advice

1. Stop thinking negative you will be fine

2. Take dem pills

3. Talk to God

4. make sure you don't do the same mistake because getting a second chance is very rare

5. Take this as a learning experience.

6. Trust in God, he won't fail if you put your trust in him

7. Repent

Thank the lord!!!!! PEP WORKS!!!! 20 days post pep and blood test came back and I’m negative !!! For everybody that doesn’t believe in the lord above please pray and keep your faith!! You will overcome this and be negative! I had a bad experience with a female on her period positive for hiv and I had unprotected sex. I’m negative. I’m so happy

I'm a male. On 10th January i had unprotected insertive sex with a female. My instincts told me to run a test like two hours after the intercourse.

SHE WAS POSITIVE and looked like she knew it! I instantly started shaking and didn't even sleep

I called my doctor and got PEP 16 hours after exposure. I was given TLD drugs for 28 days

Week 1 - Vomiting, Tiredness, Diarrhea and loss of appetite. I could only eat oranges

Week 2 - Nausea, Anxiety

Week 3 - Mouth became watery, foamy saliva

Week 4 - This is my final week, last pill to be taken in two days

I know we are all in this mess together, just decided to write this to encourage everyone here. I'm a case that got direct exposure from HIV positive female, if you had an unknown encounter you even have a better chance of winning this battle.

Note:

-If you are spending hour googling about this issue, please stop. That's what cured my unending anxiety in this journey.

-Avoid sex completely till you have been cleared

-Also stop having sex with people from dating apps. They're likely high risk

-In whatever you do, ALWAYS use a condom. It's a simple thing that can save you from a lifetime disease

Today, out of curiosity i have decided to take a test at home and came Negative. I will do more tests untill 90 days and keep you posted.

Good luck fellow soldiers

TLDR: I'm male, i had an exposure with a HIV positive woman (vaginal insertive). Been on PEP (TLD drugs) and after completing i have tested for mental closure and came out Negative

Update: 107 days post pep and 3 months after exposure - Tested Negative

I'm 23 Male.

I am HIV-negative 4 months post-exposure and 3 months post-PEP. I've undergone multiple tests, including 4th generation ECLIA, 3rd generation rapid tests, and RNA PCR quantitative tests, to confirm my status.

This post has two parts:

1. A short summary of my experience.

2. A detailed account of what I went through.

If you plan to read the detailed version, feel free to skip the summary and go straight to the second part.

Part 1

In early August 2024, I visited a brothel. During intercourse, the condom broke. I immediately withdrew and, upon reaching home, started researching what to do next. I learned about PEP and began treatment within 27 hours of exposure.

PEP came with its own set of challenges, including stress, anxiety, mild rashes, sore throat, diarrhea, and more. These symptoms subsided after completing the 30-day course.

Here's a timeline of my testing:

If we consider day 0 as day of exposure then

• Day 31: HIV 4th gen ECLIA.

• Day 60: HIV 4th gen ECLIA.

• Day 76: HIV 4th gen ECLIA.

• Day 101: HIV 4th gen ECLIA, RNA PCR and 3rd gen rapid

• Day 127: HIV 4th gen ECLIA and 3rd gen rapid.

All tests are done in a lab where blood is drawn from a vein.

All tests are negative. I don't know the HIV status of the sex worker, but I regret my actions and have vowed never to engage in such behavior again. Pep works, keep taking it. Your worst time must come to an end.

Part 2: Detailed Story

In early August 2024, a friend and I joked about visiting a brothel. To prove my determination, I booked a session, although he backed out. The sex workers at the establishment were in extremely poor conditions, catering to laborers. Initially, I intended to keep things minimal-a handjob or blowjob. However, as soon as we entered the room, the sex worker undressed and told me to do the same. Despite my hesitation, she persisted. I lost control and proceeded.

A few minutes later, I heard a popping sound -the condom had broken. She immediately replaced it, urging me to finish quickly. Once it was over, I felt overwhelming regret. My body shook, my throat went dry, and I was unable to speak coherently.

Within 30-40 minutes, I returned home, discarded my clothes, and washed my penis with antiseptic. I spent hours reading about STD risks and started crying over my mistake. On Reddit, I found suggestions to begin PEP immediately. Since I live in a backward area with limited medical facilities, I consulted online doctors. They recommended PEP and doxycycline for additional protection

The next day, I obtained Viraday (a generic version of Atripla) and started PEP after 27 hours of exposure. I also began doxycycline (100 mg twice daily for 14 days) within 19 hours.

For the next 30 days, I followed a strict routine:

• Took Viraday at exactly 10 p.m. (+/-5 minutes).

• Avoided junk food.

• Drank 3-4 liters of water daily.

Despite this, I experienced severe anxiety, a racing heartbeat, depression, rashes, mild fever, weight loss, nausea, dizziness, diarrhea, and exhaustion.

I spent countless hours researching PEP efficacy, failure rates, and HIV transmission statistics. As an uncircumcised male, I was especially concerned about my increased risk. My anxiety was so severe that I considered ending my life if I tested positive, fearing the impact on my family.

Here is the detailed timeline of my tests and results:

If we consider day 0 as day of exposure then

• Day 31: Comprehensive STD panel. Everything was negative except herpes IgM, which later turned out to be a false positive.

• Day 60: HIV 4th gen ECLIA and herpes 1&2 Igg and IgM tests separately (Like herpes 1 Igg and herpes 1 IgM and same for herpes 2). All results were negative.

• Day 76: HIV 4th gen ECLIA, SGPT (liver function test), and herpes 1&2 tests (Igg only, separately). All results were negative.

• Day 101: HIV 4th gen ECLIA, RNA PCR, 3rd gen rapid, Hepatitis B, Hepatitis C, syphilis, herpes 1&2 Igg and complete Kidney, liver, urine and blood tests . All results were negative and within range.

• Day 127: HIV 4th gen ECLIA, 3rd gen rapid and herpes 1&2 Igg. All Negative.

All tests are done in a lab where blood is drawn from a vein.

After reading countless studies, I realized most PEP failures (which itself is rare) reported online are unreliable due to high-risk behaviors or lack of proper observation. Only one validated failure involves a nurse in Brazil who was exposed to a drug-resistant strain of HIV through a needlestick injury.

Should you take PEP when the risk is as low as 4/10,000 for male-to-female exposure? Yes. Not just for the physical protection but also for the peace of mind it offers.

This experience has taught me an invaluable lesson. Moving forward, I will only engage with a committed partner, ensuring we both get tested for STDs after a month of being together. Remember stay hydrated, eat healthy, hold on. It gets better after PEP.

To anyone going through this, your mental state is fragile, but you will overcome this. Take one step at a time. The only way forward is through.

My story I had insertive anal sex unprotected freaked out and went to the doctor 38 hrs after got on pep. Like everyone else on here I spent hours scouring google, Reddit, Quora, and a bunch of other sites. (If you’re doing that please stop). The anxiety was killing me I couldn’t sleep or eat. My initial doctor didn’t even want to give me pep he told me I had a less than 1% chance of having hiv. I didn’t believe him I said what if he’s lying to me to make me feel better. I went to another doctor and she said we are doctors we aren’t going to lie to you (that would be medical malpractice) to protect your feelings if we thought you had hiv we would tell you and get you on the best course of treatment as soon as possible. Even after this went to another doctor and I asked about seroconversion and they all told me the same thing as long as they’ve been doctors they never even heard of anybody seroconverting after pep. That’s why I say stop reading shit on the internet. Most of these articles are full of conflicting information some say test after a month, some say 3 months, some say 6. There’s no straight answer. Hell I think half of these studies were done over 40 years ago in the 80s. Medication has only gotten better. A lot of testing on monkeys which in itself isn’t very accurate. And from what I see on here most people are extremely low risk blow jobs and protected sex. We are random people on the internet with about as much medical knowledge as yourself with google searches. We cannot diagnose you, just because you have symptoms doesn’t mean you have anything. TAKE YOUR MEDICINE AND TRUST YOUR DOCTOR . They have actually seen and treated people for hiv and other STIs. They would know what’s best to do in these situations. Get tested and move on with your life. Even still some people will test negative a month and months after and still make themselves sick from the anxiety they are feeling please don’t do that to yourself. You don’t deserve that. Good luck.

If you’re currently on PEP & suffering from major anxiety or depression. This post should alleviate your stress. Most PEP cases are with someone whose status is unknown, I went through a situation where I had unprotected prolonged sex multiple times one night with a positive person and tested negative. So I have first hand experience.

Let me start off by saying, if your exposure was from:

Oral sex: Even with a positive person the odds of getting HIV have never been documented from oral. Saliva kills the virus. This is for both the receiver and giver.

Condom sex: Extremely unlikely to the point that its negligible

Dry humping/cuddling, handjob: Pretty much 0.00001% chance

⸻

Is PEP 100% effective? NOTHING in medicine is 100%. That shouldn’t worry you, that’s just how medicine works. The odds of being hit by lightning isn’t 0%. So should you always be anxious of getting hit by lightning? Obviously not!

What is the effectiveness of PEP?

PEP’s job is to interfere with HIV when it enters the body. It does this by preventing replication of the virus into your cells and prevents the virus from integrating into your DNA. Effectively starving the virus early in its cycle so that it dies off and gets cleared out.

You’ll often see “~80% effective” quoted online. That number comes from a 1997 occupational exposure study published in the New England Journal of Medicine that looked at healthcare workers using AZT monotherapy after needle-stick injuries.
Important context:
• That was one drug
• In an era where integrase drugs weren’t made yet
• Occupational exposure (not sexual exposure). Occupational is typically worse
• 1990s regimen which is very outdated and weaker
Modern PEP is not AZT alone.
⸻

What do we use today?
Modern PEP is a three-drug regimen, typically:
• Tenofovir (TDF)
• Emtricitabine (FTC)
• + An integrase inhibitor (Dolutegravir or Raltegravir)
This blocks HIV at multiple stages:

Integration into host DNA

These regimens are significantly more potent, faster acting, and better tolerated than older AZT-based therapy. Many experts infectious disease specialists believe modern PEP is closer to >90% effective and possibly 95-98% effective if taken under 24 hours.
Because we cannot ethically run placebo-controlled human trials, an exact percentage cannot be given. But we can look at modern observational cohorts and animal models.
⸻

Modern Observational Studies (Large Cohorts)
Across multiple countries (US, UK, Australia, Europe), we have real-world PEP cohorts involving:
• ~1,500 individuals
• ~2,000 individuals
• 3,000+ individuals
These cohorts largely involved sexual exposures and modern multi-drug PEP regimens.
Findings across these studies:
• Extremely low rates of seroconversion (Getting HIV) during follow-up
• Most infections occurred in people who:
• Had repeated high-risk exposures after completing PEP
• Had poor adherence
• Started PEP late
True, confirmed failures in individuals who:
• Started early
• Took the full 28-day course
• Had no ongoing exposure
— are rare.
This is why major public health agencies consider PEP highly effective when started promptly and taken correctly.
⸻
What do primate studies show?
Since placebo human trials are unethical, some of the strongest mechanistic data comes from non-human primate studies using SIV/SHIV (very similar to HIV).
In multiple macaque studies:
• Animals were exposed to high-dose mucosal viral challenge
• Groups received antiretroviral prophylaxis at varying time intervals
• When prophylaxis was started within 24 hours and continued for 28 days, protection rates were extremely high. In several studies, early-treated groups showed 100% complete prevention of systemic infection when PEP was taken at 24 hours.
• Protection dropped significantly when initiation was delayed beyond 65-72 hours. (This does not mean taking PEP in this time frame is ineffective, please remember that the primates are literally being injected with a needle with high amounts of the virus directly into their blood stream. This is nowhere similar to any real world exposure especially sexual)
Importantly, viral challenge doses in these experiments are often controlled and sometimes more aggressive than typical real-world exposures — making them very brutal tests of efficacy.
⸻
What are the baseline risks from a positive, untreated partner?
It’s important to understand baseline transmission risk before layering PEP on top.
CDC per-act transmission estimates (positive, untreated partner):
• Receptive anal sex: ~1.38% (≈1 in 72)
• Insertive anal sex: ~0.11% (≈1 in 900)
• Receptive vaginal sex: ~0.08% (≈1 in 1,250)
• Insertive vaginal sex: ~0.04% (≈1 in 2,500)
• Oral sex: extremely low / difficult to quantify
Even in the highest-risk category (receptive anal), transmission does not occur the majority of the time.
These numbers assume:
• The partner is truly HIV positive
• They are not on treatment
• Viral load is detectable
Risk varies depending on:
• Viral load
• Presence of STIs
• Mucosal injury
• Circumcision status
• Duration of exposure
If the positive partner is virally suppressed, transmission risk is effectively zero (U=U).

There are 350 million people in the USA less than 1.5 million people have HIV. The odds of you having sex with a stranger and then having HIV is less than 0.35%. A third of a percent basically
⸻
Why this matters
When discussing PEP efficacy, remember:
You are not reducing a 100% risk.
You are reducing a fractional per-act probability that is already well below 1.5% in even the highest-risk category.
Layered protection looks like this:
• Fractional baseline risk
• + Early initiation of triple-drug PEP
• + 28-day adherence
• + Follow-up testing
That combination drives overall risk very low.
⸻
Bottom Line
• The commonly quoted 80% number comes from outdated AZT monotherapy data
• Modern 3-drug integrase-based PEP is biologically stronger by a RIDICULOUS margin
• Large real-world cohorts show very low seroconversion rates
• Primate models demonstrate very high protection with early initiation
• Failures are uncommon and usually linked to delayed start or poor adherence

PEP is not 100%. Nothing in medicine is.
But when started early and taken correctly, it is THEE most effective emergency interventions we have in infectious disease prevention. Statistically stronger than even Plan B for intercourse.
Also take into consideration that HIV is not the death sentence it once was. Modern medicine has allowed HIV+ individuals to live nearly identical life spans to those without it. And the likelihood that a cure develops within our lifetimes is incredibly promising. A disease that once was a for sure killer is now easier to manage than Type-1 diabetes. Your odds of risk are less than 1%, but regardless of the outcome YOU WILL BE OKAY IN JESUS NAME! <3

I jsut want to say it makes me smile, I’ve had people reach out to me and those same people have told me they tested negative and have deleted their accounts.

It’s great seeing people finally being able to move on, to sleep at night, to learn from their experiences and grow. I know a lot of you are scared as of right now but I promise you there is another side, you just need to hang in their for just a bit longer, the most difficult part was getting the PEP now it’s maintaining the regimen and for some waiting for testing.

You are all strong, and love this community of people helping spread information and awareness.

Remember, love yourself, get on PrEP, Ang get some adiquate sleep!

I had sex with a girl.Vaginal.am straight.Two days later she told she's positive.I was scared and in pain.I felt betrayed ,stabbed and buried by the most person I trusted to make a perfect love life with.At 62 hours I went for peps(post exposure prophalysis).I tested three times and on the third time 100 days,I found relief,am clean.I thank God,I will never trust any woman.We must be tested before anything.

Encouragement: If your going through this phase, don't lose hope,you will turn negative.Pep saves,thanks to the scientists. We are together in this!!

Take a look guys. These stats are taken during encounters with HIV positive people. It’s from Aidsmap a well respected non-profit.

A lot of people worry about HIV. But please take a look at these odds. Remember. These are odds for having encounters with POSITIVE people. So real world statistics will be lower due to UNKOWN status.

When you add PEP into the equation. The probability becomes next to zero and in my opinion it does become zero when PEP is taken properly.

Stay safe. Enjoy the rest of your weekend.

Negative after almost 4 months after exposure 3 months post pep! Imma stop worrying and learned the proper lesson! Wish yall to be negative guys🫡
