Post-exposure prophylaxis (PEP)

Post-exposure prophylaxis (PEP) is a preventative medical treatment given after potential exposure to a harmful virus, such as HIV, to reduce the chance of infection. It involves taking specific medications immediately or soon after the exposure, ideally within 72 hours, and completing the full course as prescribed. PEP is most effective when started promptly and is used in situations like contact with HIV-infected blood or sexual exposure. It is not a guarantee but significantly lowers the risk of developing the infection if administered correctly and promptly.
