Pre-exposure prophylaxis (or PrEP) is when people at very high risk for HIV take HIV medicines daily to lower their chances of getting infected. PrEP can stop HIV from taking hold and spreading throughout your body. It is highly effective for preventing HIV if used as prescribed, but it is much less effective when not taken consistently.

Daily PrEP reduces the risk of getting HIV from sex by more than 90%. Among people who inject drugs, it reduces the risk by more than 70%. Your risk of getting HIV from sex can be even lower if you combine PrEP with condoms and other prevention methods. What is PrEP?

Pre-exposure prophylaxis (or PrEP) is when people at very high risk for HIV take HIV medicines daily to lower their chances of getting infected. A combination of two HIV medicines (tenofovir and emtricitabine), sold under the name Truvada® (pronounced tru vá duh), is approved for daily use as PrEP to help prevent an HIV-negative person from getting HIV from a sexual or injection-drug-using partner who’s positive. FDA has approved Truvada® for PrEP for HIV-negative adults and adolescents weighing at least 35 kg (approximately 77 lbs.) Studies have shown that PrEP is highly effective for preventing HIV if it is used as prescribed. PrEP is much less effective when it is not taken consistently. Why Take PrEP?

For those at very high risk for HIV, PrEP can significantly reduce your risk of HIV infection if taken daily. Daily PrEP use can lower the risk of getting HIV from sex by more than 90% and from injection drug use by more than 70%. You can combine additional strategies with PrEP to reduce your risk even further. Should I Consider Taking PrEP?

PrEP is for HIV-negative adults and adolescents who are at very high risk for getting HIV from sex or injection drug use. The federal guidelines recommend that PrEP be considered for people who are HIV-negative and in an ongoing sexual relationship with an HIV-positive partner.

If you have a partner who is HIV-positive and are considering getting pregnant, talk to your doctor about PrEP if you’re not already taking it. PrEP may be an option to help protect you and your baby from getting HIV infection while you try to get pregnant, during pregnancy, or while breastfeeding.

Because PrEP involves daily medication and regular visits to a health care provider, it may not be right for everyone. And PrEP may cause side effects like nausea in some people, but these generally subside over time. These side effects aren’t life threatening. See Is PrEP safe?, below .

PrEP can cause side effects like nausea in some people, but these generally subside over time. No serious side effects have been observed, and these side effects aren’t life threatening. If you are taking PrEP, tell your health care provider about any side effects that are severe or do not go away. How Can I Start PrEP?
