PrEP is short for Pre-Exposure Prophylaxis. It is a new HIV prevention method in which people who do not have HIV take a daily medication to reduce their risk of becoming infected with HIV. When used consistently, PrEP has been shown to reduce the risk of HIV infection among adult men and women at very high risk for HIV infection through sex or injecting drug use.

For some individuals at high risk for HIV infection, PrEP and PEP may represent a much-needed additional prevention method, but it will not be right for everyone and is not intended to be used in isolation, but rather in combination with other methods to reduce the risk of getting HIV infection. If it is delivered effectively and targeted to those at highest risk, PrEP and PEP may play a role in helping to reduce the significant continuing toll of new HIV infections in the United States.

Useful PreP Links: PrEP, short for pre-exposure prophylaxis, is a relatively new HIV prevention strategy in which an HIV-negative person takes a daily pill to reduce the risk for HIV infection. PrEP has made headlines recently-and the messages haven't always been clear. Watch this video to get the facts about how PrEP works and see three PrEP myths busted.

PEP (Post-Exposure Prophylaxis)

PEP is a month-long course of drugs that, if taken within 72 hours of the HIV virus entering the body, can prevent a person becoming infected with HIV. The PEP drugs are the same drugs that people who have the HIV virus use to reduce its impact on the body.

Contact the STD Clinic at Denver Public Health (303.602.3540) or your healthcare provider for more info on PEP. HeyDenver does not distribute PEP.
