PrEP and PEP

PrEP (Pre-Exposure Prophylaxis)

Learn general information about PrEP and how the pill can protect you from getting HIV.

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.

Alejandro and his partner have been together for several years and they are a mixed status couple-- one HIV-negative, the other positive. Here, Alejandro describes some of the things he and his partner thought about when they were deciding whether or not to use PrEP.

Jonathan recently ended a long-term monogamous relationship. He's been a little depressed but he's also chatting online and dating quite a bit. Like many of us, he doesn't always use condoms. Listen to Jonathan talk about how PrEP has helped ease his mind as he's working through this new stage in his life

Marcus is just starting out on his own: he just got his own apartment, he's exploring his interest in music and getting out on the dating circuit. Here, Marcus talks about not always using a condom and why PrEP may be right for him. He wonders if it's enough if the other guy tells him he's negative. 

PrEP is short for Pre-Exposure Prophylaxis. It is a HIV prevention method in which people who have a negative HIV status 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 by 92%.

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

PEP (Post-Exposure Prophylaxis)

PEP is a month-long course of drugs that, if taken within 72 hours of a HIV exposure, can prevent a person becoming infected with HIV. 

This is a time sensitive treatment. If you feel like you need PEP, contact the STD Clinic at Denver Public Health (303.602.3540), your healthcare provider or an emergency room as soon as possible. HeyDenver does not distribute PEP but we can give you more information on it!
