A member asked:

I have just been given pep!(48 hours after exposure via unprotected insertive anal sex with a prostitute) how much does this reduce my risk of hiv by?

A doctor has provided 1 answer

Very effective: To be effective, pep must begin as soon as possible, but always within 72 hours of exposure. There have been cases where pep has not prevented HIV but overall it appears very effective.
