What is a Prep Treatment?
PrEP, or pre-exposure prophylaxis, is medicine people at risk for HIV take to prevent getting HIV from sex or injection drug use. PrEP can stop HIV from taking hold and spreading throughout your body.
PrEP is highly effective at preventing HIV when taken as indicated.
PrEP reduces the risk of getting HIV from sex by about 99% when taken as prescribed. Among people who inject drugs, it reduces the risk by at least 74% when taken as prescribed. PrEP is much less effective when it isn’t taken consistently.
