Question

Do I need to re-start event based PrEP?

27 March 2023. Related: Adherence, All topics, PrEP.

I am on event based prep, starting my 2 dose on Tuesday but end up not having sex, so I didn’t take my daily prep on Wednesday and Thursday. I want to have sex on Saturday, do I take 1 dose or 2 dose on Saturday morning?

I have taken 2 doses, is that going to be a problem? The guideline says I will need to take 2 doses as I didn’t complete the 2 daily doses required.

Hi, how are you?

Taking the double dose is correct. As you did not continue with your daily PrEP on Wednesday and Thursday, a second double dose would be required for event based PrEP.

Taking 2 doses is not going to be a problem. Taking a double dose is regularly done and will not have an impact on how it works.
