PEP stands for post-exposure prophylaxis. It is not a specific drug, but rather a type of medication used to prevent HIV infection after a possible exposure.
How PEP Works:
PEP involves taking a combination of antiretroviral medications for a specific period, typically 28 days. These medications work by preventing the HIV virus from replicating and spreading within the body.
When to Use PEP:
PEP is recommended for individuals who may have been exposed to HIV through:
- Unprotected sex: This includes anal, vaginal, or oral sex without a condom.
- Needle stick injuries: This includes accidental needle pricks or sharing needles.
- Other bodily fluids: This includes contact with blood, semen, vaginal fluids, or breast milk.
Important Considerations:
- PEP must be started as soon as possible after exposure, ideally within 72 hours.
- PEP is most effective when started within 24 hours of exposure.
- PEP is not a substitute for safer sex practices.
Availability and Access:
PEP is available through healthcare providers, including hospitals, clinics, and emergency rooms. It is important to contact a healthcare professional immediately after a potential exposure to discuss PEP options.
