PEP: The Emergency Treatment After HIV Exposure

PEP (Post-Exposure Prophylaxis)
Is an emergency medication for people who are HIV-negative and may have been exposed to HIV. If you think you were exposed to HIV, go immediately to a clinic or emergency room and ask for PEP.

How do I know if I need PEP?
If you are HIV-negative, PEP can protect you if you had anal or vaginal sex without a condom (or your condom broke) with someone who has HIV or may have HIV. PEP can stop HIV if you were the victim of sexual assault. PEP can also stop HIV if you were exposed while injecting drugs. You may be at higher risk of HIV infection if you were the receptive (or “bottom”) partner in anal or vaginal sex (if you had a partner’s penis in your anus or vagina). Receptive partners have a greater chance of exposure to HIV through semen or blood.

How do I start PEP?
PEP works best if started right away. Go to an emergency room or clinic as soon as possible after the exposure to HIV and ask about PEP. You should begin PEP no more than 36 hours after exposure. PEP is taken in pill form for 28 days. You need to take PEP each day to keep enough medicine in your body to stop HIV.



How does PEP stop HIV?

PEP contains some of the same medicines that people with HIV take to stay healthy. If you are exposed to HIV, it takes a few days for an HIV infection to take hold in your body. As soon as you start PEP, these medicines begin to stop the virus from multiplying. As you continue taking PEP for the full 28–days, cells with HIV die and the virus stops spreading to the rest of your body.

condom protection even when using PEP If I take PEP, do I still have to use condoms?
PEP does not provide full protection against HIV. Condoms give you and your partners additional protection, even while on PEP. Condoms also protect against other sexually transmitted infections (STIs) and unintended pregnancy. PEP is for emergency situations. If you worry about regular exposure to HIV through sex or while injecting drugs, PrEP may be a better option for you.
