PrEP is used by people who are HIV negative to help prevent them from getting HIV. It involves taking a prescription pill that contains two medications, emtricitabine and tenofovir. It is very important to take the pill as prescribed for it to work.
Taking PrEP also involves seeing a doctor or nurse every three months for HIV testing, screening for other sexually transmitted infections (STIs), monitoring for possible side effects, and ongoing support.
PrEP is for people who are at ongoing risk for HIV. PrEP may be a good option for anyone who is HIV negative and:
- sometimes has vaginal or anal sex without using a condom and doesn’t know the current HIV status of one or more of their sex partners
- has a sex partner who is HIV positive and is not maintaining an undetectable viral load while on treatment
- sometimes uses injection drugs and shares needles
People who are interested in taking PrEP should talk to a medical professional to see if PrEP is right for them. Learn more about PrEP:CATIE-PrEPbrochure-2021-en
