What Is PrEP and How Does It Work?

PrEP (Pre-Exposure Prophylaxis) is an antiretroviral medication used to prevent HIV infection before exposure to the virus. It works by blocking the virus from replicating and spreading in the body. When taken consistently and at the same time every day, PrEP can reduce the risk of HIV transmission by nearly 100%. It is a highly effective prevention method, particularly for individuals who engage in higher-risk behaviors.

Starting PrEP the Right Way

To ensure maximum effectiveness, PrEP should be taken at least 7 days before any potential sexual exposure and must be continued daily—one pill at the same time each day. Skipping doses or inconsistent use may reduce the level of the drug in the bloodstream, lowering its ability to protect against HIV. Discipline and consistency are key factors in making PrEP a reliable part of your prevention strategy.

PrEP Should Be Used Under Medical Supervision

PrEP should always be used under the guidance of a qualified healthcare provider. Before starting the medication, you will need a full health assessment, including HIV testing, to confirm that you are not already infected. Regular follow-ups are also necessary to monitor your health and ensure the medication is working safely and effectively. Your doctor will help guide you through this process with expert care and advice.

Effective for HIV, But Not for Other STIs

While PrEP is extremely effective in preventing HIV, it does not protect against other sexually transmitted infections such as syphilis, gonorrhea, or genital warts. Therefore, it is strongly recommended to use condoms in conjunction with PrEP for broader protection. Combining these methods helps protect both you and your partners from a wide range of infections.

Knowledge Is the Key to Protection

Understanding what PrEP is and how to use it correctly is a vital step toward better sexual health in today’s world. It’s not just about disease prevention—it’s about empowerment, making informed choices, and reducing stigma around HIV. PrEP is more than just a pill; it’s a tool that allows individuals to live freely, confidently, and safely, with control over their own health.
