second exposure PEP

Apr 7, 2012

After being on Aspen Lamzid PEP for about 3 weeks, I had a possible exposure. Would I have to extend the treatment? If I just finish the month course after having a second exposure would I be at risk of getting HIV? Would I have to extend the treatment for an additional 3 weeks?

Response from Dr. Young

Hello and thanks for posting.

There isn't good scientific literature on this topic, particularly since one could consider your curent PEP as a pre-exposure prophylaxis (PrEP) too.

That uncertainty said, I'd be inclined to suggest treatment for an additional 3 weeks. Don't forget that when you speak to your health care provider to mention this; you should be (re)screened for other sexually transmitted infections (other than HIV).

If you have repeated risky exposures to HIV, it might also be worth a conversation about whether PrEP is suitable.

Be well, BY

PrEP duration
detectable after 2 years and a half
