Using PrEP Medication to End HIV
Pre-exposure prophylaxis (PrEP), a daily regimen of two oral antiretroviral drugs in a single pill, has proven to be highly effective in preventing HIV infection for individuals at high risk, reducing the risk of acquiring HIV by up to 97 percent. (hiv.gov)
PrEP & PEP
PrEP is an HIV prevention strategy in which HIV-negative people take anti-HIV medications before coming into contact with HIV to reduce their risk of becoming infected. PrEP protects against HIV infection much like a malaria pill protects against malaria or a birth control pill protects against pregnancy. PrEP is different from post-exposure prophylaxis (PEP). PEP is taken within 72 hours after HIV exposure and involves a month-long course of anti-HIV medications. If PrEP protects against HIV infection like the birth control pill for pregnancy, think of PEP like the morning-after pill. PrEP does not protect against other sexually transmitted infections (STIs) or pregnancy and is not a cure for HIV.
