PrEP is an HIV prevention method for people who are HIV-negative. It involves taking one pill daily to prevent HIV infection. Several studies have shown that, when taken as directed, PrEP dramatically reduces the risk of becoming infected when combined with other prevention services. The Centers for Disease Control and Prevention currently recommends PrEP for all individuals who are at high risk for HIV infection.
The pill (brand name Truvada®)
is a combination of two anti-HIV medications (tenofovir and
emtricitabine). Truvada® is commonly used to treat HIV positive
individuals in combination with other anti-HIV medications. In
2012 the Food and Drug Administration approved Truvada for
the prevention of HIV-infection in HIV-negative individuals.
