Post-exposure prophylaxis

Post-exposure prophylaxis (PEP) is a preventive medical treatment given after potential exposure to an infectious disease, like HIV, to reduce the chance of becoming infected. It typically involves taking a combination of antiviral medications for a specified period, usually 28 days. PEP is most effective when started promptly, ideally within hours of exposure, and is used in situations such as contact with infected blood or sexual exposure. It doesn’t guarantee prevention but significantly lowers the risk when administered early and correctly. PEP should be initiated under medical guidance to ensure proper treatment and follow-up.
