When you think of HIV prevention, condoms are probably the first thing that comes to mind (which is great, because they should! Condoms are a proven method to reduce your risk for HIV and other sexually transmitted infections during intercourse.) But there is another option for those who may be at higher risk for HIV—pre-exposure prophylaxis, or PrEP.
PrEP involves taking a pill once daily to prevent HIV infection in someone who is HIV-negative. The pill—approved by the Food and Drug Administration (FDA) as PrEP in 2012 and marketed under the brand name Truvada—contains a combination of two antiretroviral drugs that stop the virus from reproducing in the body. When taken consistently, every day, PrEP has been shown to reduce the risk of HIV infection in people who are at high risk by more than 90%.
