PEP should be used only in emergency situations and initiated within 72 hours after a potential HIV exposure and continued for a duration of 28 days. Ideally, PEP should be initiated within hours of an exposure. In cases involving a high risk for transmission, PEP may be considered after a longer delay of therapy initiation (eg, 1 week). For prolonged delays in initiating PEP, the risks of ART most likely outweigh its benefits, although the exact period in which this is determined has not been defined.
