What is PrEP?

PrEP stands for pre-exposure prophylaxis. It’s a daily pill that can help prevent HIV. PrEP is also known by the brand name Truvada.

Who can use PrEP?
PrEP is for people who don’t have HIV, and are at higher risk for getting HIV.

You may want to talk with a doctor or nurse about PrEP if you:

  • Don’t regularly use condoms.
  • Have a sexual partner who has HIV (sometimes called serodiscordant, serodifferent, magnetic, or mixed status couples).
  • Have a sexual partner who is at high risk for getting HIV (like if they have anal or vaginal sex with other people without condoms, or they’re an injection drug user).
  • Have anal or vaginal sex with many partners, especially if you don’t use condoms regularly.
  • Recently had another STD (like chlamydia, gonorrhea, or syphilis).
  • Do sex work that includes vaginal or anal sex.
  • Have injected drugs, shared needles, or been in treatment for drug use in the past 6 months.
  • If you’re at high risk for HIV and you’re pregnant, trying to get pregnant, or breastfeeding, PrEP may also help you and your baby avoid getting HIV.


What is PEP?

PEP stands for post exposure prophylaxis. PEP is a series of pills you can start taking very soon after you’ve been exposed to HIV that lowers your chances of getting it. But you have to start PEP within 72 hours, or 3 days, after you were exposed to HIV, or it won’t work. The sooner you start, the better it works — every hour matters.
