When taken as prescribed, PrEP – the HIV prevention pill – is highly effective! If you’re exposed to HIV while taking PrEP, the medicine can block HIV from taking hold in the body. In a major study of gay and bi men, as well as trans women, daily PrEP use lowered their risk of getting HIV by an estimated 99 percent – that’s pretty amazing!
If you decide to start PrEP, remember that it will take some time for the pill to reach maximum effectiveness – at least seven days for men who have sex with men, and longer if you are a woman having vaginal sex.
