PEP stands for Post-Exposure Prophylaxis.
Post-Exposure Prophylaxis (PEP) is an urgent medical response involving the use of antiretroviral (HIV) medicines to prevent HIV infection after a potential exposure. It is a critical intervention designed to stop the virus from taking hold in the body.
Understanding Post-Exposure Prophylaxis (PEP)
PEP is a course of HIV medicines taken within a specific timeframe after a possible exposure to HIV. This treatment aims to prevent the virus from establishing a permanent infection.Key facts about PEP include:
- Timing is Crucial: For PEP to be effective, it must be started as soon as possible, ideally within hours of exposure, and no later than 72 hours (3 days) after a possible exposure to HIV. Every hour counts in the effectiveness of the treatment.
- Mechanism: PEP works by inhibiting the HIV virus from replicating and spreading throughout the body if it has entered. By taking a combination of HIV medications, the goal is to prevent the virus from taking root.
- Emergency Use Only: It is important to understand that PEP is intended for emergency situations only. It is not designed for routine or regular use by individuals who might be frequently exposed to HIV. For ongoing prevention for individuals at high risk, other strategies like Pre-Exposure Prophylaxis (PrEP) are available.
- Types of Exposure: PEP can be used after various types of potential HIV exposure, including unprotected sex, sharing injection drug equipment, or occupational exposures (e.g., healthcare workers experiencing needle sticks).
