PrEP is a daily pill taken to lower a person’s risk for getting HIV. It works best as part of a program of preventive services that includes regular HIV testing.
Global research during the past decade shows that a combination of two antiretroviral medicines is more than 90% effective at preventing HIV.
The Centers for Disease Control and Prevention (CDC) and many expert guidelines recommend PrEP for those at high risk for HIV, including
- men who have sex with men
- heterosexual men and women who have high-risk exposure (such as having a partner with known HIV infection, exchanging sex for drugs or money, or having sex with a person at high risk for HIV)
- people who inject drugs
- transgender women.
