What is PrEP

PrEP is medication you take before sex or sharing a needle to protect yourself from HIV. PrEP is for people of all genders and more than 99% effective against HIV when taken as directed.

PrEP comes in the form of a pill or a shot. You can take it even if you drink alcohol, use drugs, take hormones, or use birth control.

Four medications are FDA-approved for PrEP. Compare your options for PrEP below to decide which one is right for you.
