PrEP involves the use of any anti-HIV agent before, during and usually after sex to prevent infection. Today, PrEP refers primarily to taking the HIV treatment Truvada every day along with using condoms. What we know about PrEP is that even in people who don’t use condoms regularly, it can work amazingly well if taken exactly as prescribed. Two studies have found that daily use could be almost 100-percent effective.
