Pre-exposure prophylaxis (PrEP) is a preventive medication for individuals at high risk of contracting HIV. It involves taking a daily pill that contains antiretroviral drugs, which help reduce the chances of getting infected if exposed to the virus. When taken consistently, PrEP can lower the risk of HIV transmission by more than 90%. PrEP is most effective when combined with other preventive measures, such as using condoms and regular testing for HIV and other sexually transmitted infections. It is important for individuals considering PrEP to consult with a healthcare provider to discuss their risk factors and determine if it is the right option for them.
