Is PEP recommended if I am on PrEP?

PEP stands for post-exposure prophylaxis and involves taking a combination of three HIV meds for one month.

PEP is rarely used, but if you need it, the earlier you start PEP, the more likely it will work. PEP can be prescribed up to 72 hours after sex but is most effective if started within 24 hours

  • If you have a risk when you haven’t been taking PrEP, or enough PrEP, contact a clinic to discuss whether you might need PEP.
  • Taking a double-dose of PrEP (if you still have some left) is a good idea as the earlier PEP is started the better it works.
  • PEP is sometimes used as a response after a sexual assault. In this case, it is important to get care and support as soon as possible.
