Question
Have I taken on-demand PrEP correctly?
12 July 2023. Related: Adherence, All topics, PrEP.
Am I at risk? I was meant to have sex on Friday but I had sex on Saturday. Here is how I took my 2-1-1 dose
Friday (8pm) – 2 pills
Saturday (8pm) – 1 pill
Saturday (11:30pm) – had sex
Sunday (8pm) – forgot to take my after sex pill
Monday 7am – took the pill 11 hours late
Monday (8pm) – took the 2nd day pill
Answer
Hi, how are you doing?
Did you take a following dose on Tuesday?
As you had started with you had sex after your second pill, on-demand PrEP would require 2 further days of pills to be taken after sex.
In this case 8pm Monday and 8pm Tuesday.
You did take 2 pills on the Monday. This would provide some protection and some PrEP is definitely better than no PrEP.
As you had recently started with a double dose there would be PrEP in your body, but it may not be as effective as if taken following a normal regimen. This would still be considered relatively low risk.
Was this a risky exposure?

Hello Jay and thanks for getting in touch
It’s absolutely great as a dosing schedule, you were covered, since you had more than 4 doses in a week

Hi,
I would like to know if I have taken Prep correctly.
17 Feb Mon – 2 pills @ 3pm (no sex)
18 Feb Tue – No sex , 0 pills
19 Feb Wed – 2 pills @ 8:30pm (no sex)
20 Feb Thurs – 1 pill @ 8:30pm
20 Feb Thurs – Sex 10pm-2am
21 Feb Fri – 1 pill @ 6pm
22 Feb Sat – 1 pill @ 8pm
23 Feb Sun – 1 Pill @ 8pm (unsure but most likely)
I’m unsure if i took the pill on Sunday. Is there enough protection with what I have already taken before Sunday?
Thank you.
