PEP is only given to people who are HIV negative but think they have come into contact with HIV. If you have been raped or sexually assaulted, are a person who injects drugs and shares needles, or you had sex without a condom, PEP is for you.
Note: PEP should be used only in emergency situations – it doesn’t replace other proven HIV prevention methods. Consider taking PrEP if you’ve been on PEP more than once in a 6-month period.
It is very important that you take PEP within 72 hours (3 days) of being exposed to HIV.
Remember! PEP can prevent HIV when taken correctly but it is not 100% effective. While you’re on PEP treatment, make sure you continue to use condoms with sex partners and use safe injection practices if you’re a person who injects drugs. This way, you’re protected from being exposed to HIV again and you can reduce the chances of transmitting HIV to others if you become infected while on PEP.
