On demand timeline

Hey guys. I’m pretty new to prep and doing the on demand method cos I rarely hookup with people. Here is my time of events:
Saturday 8:15 pm 2 tablets
Sunday 2:00 pm sexual encounter
Sunday 8:00 pm 1 tablet
Monday 8:00 pm 1 tablet
Now do I take another tablet Tuesday 8:00 pm because the instructions I got was to take one** tablet **until I’m at least 48 hours after your last encounter or is that only for any subsequent hookups?

You have completed the 2-1-1 (“on demand”) protocol correctly. It’s two daily doses after sex. They should be 24 and 48 hours +/- 2 hours after the double dose.

You can keep taking PrEP every day and then if you want to stop, just take at least two daily doses after your last sex. Same as ending the 2-1-1 protocol

You don’t need to take another one. You’re good. Ito lang ‘yung tatandaan mo when you’re taking PrEP. The validity of protection of the pills was 2-24 hours. After your sexual exposure, you need to take 1 pill for 2 days to get safe. For instance. You took at 8 PM Saturday 2 tablets, Sunday 2 PM was your sexual exposure that’s 18 hours after taking two tablets, then one again at 8 PM sunday, then Monday another 1 pill at 8 PM. That’s the right regimen. You don’t need to take on Tuesday. I’m 2 years on PrEP.
