Pre-exposure prophylaxis (PrEP)

Pre-exposure prophylaxis (or PrEP) is when people at very high risk for HIV take HIV medicines daily to lower their chances of getting infected. A combination of two HIV medicines sold under the name Truvada, is approved for daily use as PrEP to help prevent an HIV-negative person from getting HIV from a sexual or injection-drug-using partner who’s positive.

For those at very high risk for HIV, PrEP can significantly reduce your risk of HIV infection if taken daily.  Daily PrEP use can lower the risk of getting HIV from sex by more than 90% and from injection drug use by more than 70%. You can combine additional strategies with PrEP to reduce your risk even further.

PrEP can be prescribed only by a health care provider, so talk to yours to find out if PrEP is the right HIV prevention strategy for you. You must take PrEP daily for it to work. Also, you must take an HIV test before beginning PrEP to be sure you don’t already have HIV and every 3 months while you’re taking it, so you’ll have to visit your health care provider for regular follow-ups.

You should not stop using condoms because you are taking PrEP. PrEP doesn’t give you any protection against other STDs, like gonorrhea and chlamydia. Also, while PrEP can significantly reduce your risk of HIV infection if taken daily, you can combine additional strategies like condom use with PrEP to reduce your risk even further. If used the right way every time you have sex, condoms are highly effective in preventing HIV and some STDs you can get through body fluids, like gonorrhea and chlamydia. However, they provide less protection against STDs spread through skin-to-skin contact, like human papillomavirus or HPV (genital warts), genital herpes, and syphilis
