PEP Guide

PEP PEP (after exposure)

Post-exposure prophylaxis (PEP) is an HIV prevention strategy for people without HIV. Anti-HIV medication is taken to reduce the risk of becoming infected after a potential HIV exposure.

PEP is used in emergency situations when someone may have been exposed to the virus and has to be started within 72 hours. PEP is very effective at reducing the risk for HIV infection if started within the 72-hour timeframe and then taken for 28 days.
