Pre-exposure prophylaxis, or PrEP, is a once-daily pill that significantly reduces the risk of HIV infection in individuals who may be exposed to the virus through sexual contact or injection drug use.

​

When taken consistently as prescribed, PrEP is up to 99% effective at preventing HIV transmission through sex and at least 74% effective among people who inject drugs. It’s a powerful tool in protecting your long-term health and is recommended for anyone who may be at higher risk.
