The sooner you start PEP after a potential exposure to HIV the better, to prevent HIV infection. Clients will need to seek immediate assistance from a PEP navigator, their primary care physician, or the emergency room if they suspect a recent exposure to HIV. Possible exposures include the following:
Unprotected sex with a partner of unknown HIV status
Unprotected sex with a partner living with HIV that is not Undetectable
Sharing needles with others who are living with HIV and not Undetectable or of unknown status
Workplace accidents (e.g., frontline workers who suffer from a needle-stick injury).
PEP is not an alternative to other prevention methods, such as condoms and unused needles because PEP does not guarantee protection against HIV infection and it does not protect against sexually transmitted infections. PEP is not recommended to those who are exposed to HIV frequently.
