Postexposure prophylaxis, often abbreviated as PEP, refers to a short course of medication taken after a potential exposure to an infectious agent to prevent infection. This medical intervention is most commonly discussed in the context of human immunodeficiency virus (HIV) infection, where it is known as post-exposure prophylaxis for HIV, or PEP-HIV. PEP-HIV is a critical tool for preventing seroconversion when individuals have had unprotected sexual contact with someone whose HIV status is unknown or positive, or if they have shared needles or experienced a needle-stick injury. The medication regimen typically consists of antiretroviral drugs taken for 28 days, and it must be initiated as soon as possible after the exposure, ideally within hours, and no later than 72 hours.

Beyond HIV, the concept of postexposure prophylaxis also applies to other infectious diseases. For instance, rabies postexposure prophylaxis involves a series of vaccinations and, in some cases, immunoglobulin, given after a bite or scratch from a potentially rabid animal. Similarly, hepatitis B postexposure prophylaxis may involve the administration of hepatitis B immune globulin and/or hepatitis B vaccine to individuals who have been exposed to the virus. The specific medications and duration of treatment for PEP vary depending on the infectious agent and the route of exposure. It is crucial for individuals who believe they may have been exposed to an infectious disease to seek immediate medical advice to determine if postexposure prophylaxis is appropriate.
