PrEP is a course of HIV drugs taken by HIV negative people before sex to reduce the chance of getting HIV. Results in trials have been very successful, with PrEP significantly lowering the risk of becoming HIV positive and without major side effects.
Truvada for PrEP provides 92%-99% reduction in HIV risk for HIV-negative individuals who take the pills every day as directed. If a daily dose is missed, the level of HIV protection may decrease. It only works if you take it. People who use PrEP correctly and consistently have higher levels of protection against HIV.
