indicates that PEP can prevent infection with
HIV, but it is not 100% effective. 1, PEP is
more likely to be effective when the treatment
starts shortly after the risk occurred, and most

any later than 72 hours after HIV exposure
(risk). The sooner after the risk you begin PEP,
the better the chance that it will work.
