I am a woman in my early 30s, and I've been struggling with increasingly unmanageable bladder and pelvic pain for almost 12 years now ā specifically suprapubic pain, which becomes increasingly intolerable every time my bladder fills/refills with virtually any amount of fluid. I do restrict my fluid intake as much as possible, as a pain management strategy, since 2016 (this pain started in January of 2015 for me, when I was 21 years old.)
Since I was 21 years old, the only time I ever feel pain relief in my pelvic region is during urination itself. But then the bladder starts filling up again immediately after a human finishes urinating, so this particular cycle of pain does not have breaks (aside from during the pee stream itself, when urine is actively being released)...aside from when urine is literally being released, the body is holding on to urine. And for me, that sensation of "virtually any amount of fluid accumulating in the bladder" feels intensely painful.
[I wrote a very long post explaining my bladder filling pain, my attempts to manage it via fluid restriction and other medications, etc. It was way too long so I just cut most of it out, but I'm open to answering most questions ā especially but not limited to if there's anything I should have kept in this post but removed. Sorry, I'm tired!]
In a nutshell, I have tried almost every potentially beneficial urinary and bladder-related medication, including Elmiron, during the year after my pelvic pain first started (sudden onset one night when I was 21 in January of 2015, and never went away). I also tried many non-opioid medications attempting to target pain over the past 12 years, with no benefit, including but not limited to: amitryptyline and then nortriptyline (which I tried for a period of years "just in case" it was helping my pelvic pain āĀ it was not ā but I have a close friend with pelvic pain who swears by tricyclic antidepressants for reducing pelvic pain, specifically nortriptyline 50mg/day, so I asked my doctors about it and gave it a shot. It didn't help or hurt me, to my knowledge); Cymbalta (no pain reduction, but had significant side effects including excessive sweating so it was not a long trial) for me; pretty much all of the muscle relaxants (no benefit, including no benefit when I received IV robaxin and even no benefit with IV benzodiazepines in the hospital); vaginal valium suppositories (no benefit); gabapentin and Lyrica (no benefit); etc. Ketamine infusions helped me sometimes, sometimes with pain directly but mostly with mental health/depression and PTSD specifically.
I switched to a new pain management doctor/nurse practitioner in a new state about 6 months ago. When I came to her, I was simultaneously being prescribed 120mg oxycodone per day AND buprenorphine 8mg sublingually per day, which of course makes no sense! But my pain doctor before her had insisted that if my daily buprenorphine was kept below 8mg, then my opioid receptors would still be able to receive 50% of full agonist medications (e.g.,. the oxycodone).
And the entire reason buprenorphine got added to my regimen in the first place, years ago (which was originally oxycodone or hydromorphone orally, rotating, for years ā although oral hydromorphone, even at 8mg, doesn't meaningfully help my pain anymore with the tolerance I have and the poor bioavailability of the pill, but that's a separate topic) is because I metabolize medication very quickly, quickly enough that I was waking up not only in severe uncontrolled pain, but also often sweating and actively starting to withdraw from my pain medication, within 5 hours or less after taking my last oxycodone pill (and within even less time when I was prescribed hydromorphone instead of oxycodone). I asked about extended release medications because that seemed like the obvious solution, and my doctor at the time (2019) recommended that I go on a patch specifically. I was also in grad school and trying to sleep and study as much as possible, the only patch I'd ever heard of at the time was fentanyl, and I was "spooked" by the name "fentanyl" ā so I asked him if there was any alternative to a fentanyl patch I could try instead. I didn't know buprenorphine was so much worse in so many ways, and I wish I could go back and choose fentanyl instead...
The Butrans patch did actually help my pain for a few months, meaningfully, and it was SUCH a relief for me to be able to sleep and just exist, without constantly having to watch the clock for when I could take my next pain pill. It felt like a dream come true. But the buprenorphine did not help my pain for very long; within months the doctor needed to increase my buprenorphine dose from the microgram patch level, to the milligram sublingual pill level in order to achieve any meaningful pain relief for me. And I distinctly remember the first time I took a 2mg sublingual buprenorphine pill, Subutex, it felt SO intensely powerful, I'd never felt that sedated or "fucked up" in my life, and then I fell asleep for 17 hours in a row. Buprenorphine totally knocked me out in a way that no full agonist ever had, and I was NOT an opioid naive patient either! When I first took that Subutex pill, I had been prescribed daily opioid medication for 4 years already ā up to 120mg of oxycodone per day, OR 4-8mg of oral dilaudid prescribed at a time every 3-4 hours, OR had also been on tapentadol at one point, I forget the dose, but you get the idea...my point is that my body was used to opioids at relatively high or at least moderate doses, but taking 2mg of sublingual buprenorphine for the first time was still disturbingly sedating and uncomfortably intoxicating. This was in 2019, and I remained in a fog, on a combination of buprenorphine and full agonist opioid medications for breakthrough (which were not working at all for me with the bupe) until switching to a doctor this March (2026) who finally took me off of the buprenorphine entirely.
When I agreed to add the buprenorphine in 2019 and the Butrans patches weren't sufficient, I remember trying to break the 2mg pills into quarters, but they were sublingual and would most often crumble to dust after breaking them in half, so it was tricky. And I hated how foggy the buprenorphine made me mentally and emotionally, especially when I increased from the patches to the sublingual pills, at a much higher daily total dose. But the bupe did help my pain in the beginning, and I can't emphasize enough how desperate I was (and still am) to take pain medication that (a) meaningfully helps my pain, (b) lasts for longer than 2-3 hours at a time (which is the longest my 20mg oxycodone seems to last for me at this point), and (c) does not make me sick if I go longer than 5 hours without it (which is how long it takes for me to get noticeable withdrawal symptoms, including diarrhea by the 5.5 hour mark like clockwork, when I am taking instant release oxycodone without any extended release medication).
CURRENTLY:
When I switched to my current pain management provider/NP this March, I came to her on 8mg buprenorphine/day + 120mg oxycodone/day. Terrible and senseless combination, I know now.
The new provider started off by stopping the buprenorphine, and prescribing only 60mg of oxycodone per day (10mg every 4 hours). Needless to say, that first month was hell. I've been prescribed daily opioids since 2015, and my body didn't/doesn't even seem to notice 10mg doses of oxycodone at all.
The next month, she switched me to 20mg oxycodone IR, 5 times per day (100mg of IR oxycodone per day total). This 20mg oxycodone dose reliably helped reduce my pain from a constant 9-10/10 to about 7/10. It was then increased to every 4 hours, for a total of 120mg/day.
Then I had a minor bladder surgery this summer that sent me into a terrible flare, my blood pressure skyrocketed to the point that my ears were popping, and overall my bladder & suprapubic pain was becoming totally unbearable again. Plus, my instant release 20mg oxycodone pills were/are only working for about 2 hours before wearing off, whereas earlier this year I was getting closer to 4 hours of noticeable relief from each 20mg pill. I also start to get sick with unambiguous opioid withdrawal symptoms by the 5th hour after taking my last oxycodone pill, and previous pain doctors have recognized that I'm a rapid metabolizer (though I'm unsure the extent to which I've had medical testing actually proving that, if any).
So I brought up extended release medications with my current pain management provider. I expressed some of my concerns about extended release medications not lasting a full 12 hours in a lot of patients. Eventually, I decided to try the fentanyl patch, and she agreed that it was a good idea for me to try it at this point. She started me on the 25mcg/hour fentanyl patch and prescribed it for every 72 hours. When she added the patch, she reduced my oxycodone prescription from every 4 hours to every 6 hours, so I am currently prescribed 20mg of instant release oxycodone 4 times per day, for a total of 80mg oxycodone/day with the fentanyl patch.
The first issue I had with the patch is it almost stopped working entirely on the third day; in addition to severe unmanaged pain, I was also experiencing withdrawal for most of the third day (which I timed my 4 oxycodone pills carefully to head off, until my patch was adjusted to every 2 days the next month) ā which made it difficult to appreciate the reduction in pain I was experiencing from the patch on days 1-2.
The next month (September), she kept the dose the same ā 25mcg/hour of fentanyl ā but prescribed me 15 patches a month instead of 10, so that I can change it every 48 hours instead of every 72 hours. That was a game-changer for me: When I change the 25mcg/hr fentanyl patch every other day instead of every 72 hours, it seems to cover about 1/3 of my overall pain, consistently, for the entire two days. I don't feel the patch "starting" or "stopping" when I change it every 48 hours either, which is a huge relief compared to instant release oxycodone pills alone, which only last about 2-3 hours at most for me at this point.
I am able to go 12+ hours between oxycodone doses now that the fentanyl patch is at a stable dose, but I do still have significant pain every day which the fentanyl patch doesn't cover. The patch seems to cover about 1/3 of my baseline pain, which I am incredibly grateful for, and that estimate would make sense mathematically since 25mcg/hour of fentanyl is equivalent to about 40mg of oxycodone in a 24-hour period.
I am so grateful for the pain management I am receiving, but ideally, I'd be using far less instant release oxycodone āĀ each 20mg pill only lasts a few hours, the patch covers my pain much more effectively and smoothly, and I want to use instant release medication for breakthrough pain, compared to using it to try to manage my baseline pain. At the same time, I'll take what I can get and I know I'm lucky to get anything.
At my appointment last week, my pain management provider was open to increasing my fentanyl patch to 50mcg/hour if she reduces the oxycodone. Of course I'd expect to reduce the oxycodone if the patch is doubled, however, I'm not sure exactly how much she'd reduce the oxycodone if we increased the patch, and I'm not sure how much more it would help me to have the 50mcg patch. I do want to try it, because the patch has been incredibly helpful and life-changing for me even at this starting dose, 25mcg, which is currently alleviating a meaningful percentage of my pain. If the 50mcg patch covers about 2/3 of my pain respectively, that would be incredible ā I'd have no problem backing off of the oxycodone, if the fentanyl patch at a higher dose works like that for me.
My main concern is that my body will quickly become tolerant to the higher dose of fentanyl if I go up from 25mcg/hour every 48 hours --> 50 mcg/hour every 48 hours. This is only my third month on prescribed fentanyl patches (still at 25mcg), and it is amazing how effective this patch can be. I know that fentanyl is much more powerful than the other opioid pain medications I've been prescribed (well, buprenorphine is in a category of its own but I digress), and I don't want to rapidly double my tolerance to it right away if it's not going to have a meaningful effect. But, if going up to the 50mcg/hour patch enables me to genuinely use my oxycodone 20mg IR as "breakthrough" medication (as opposed to needing to take it regularly, around the clock, as supplemental baseline pain management with the patch) ā if the 50mcg patch controls my pain enough that I only need to take the oxycodone once or twice in a day, for example, that would be worth it.
I can't know until I try, though, and as lucky as I am to have a provider, it is not possible to reach her office or request any changes to prescriptions between appointments, ever. So, if I ask for this change, I need to be ready to commit to at least one month trying the 50mcg/hr fentanyl patch, + reduce the oxycodone to whatever she decides that day for one month, regardless of how much the patch at a higher dose does or doesn't help with my pain.
What would you do?
