What is PEP?
28-day course of antiretroviral medication taken after potential HIV exposure. Must start within 72 hours of exposure — the sooner the better. Once daily dosing (TAF/FTC + Dolutegravir). Protects against HIV only — does not cover other STDs.
When to Use
- Unprotected vaginal or anal sex
- Condom breakage or slippage
- Sexual assault
- Shared needles or needle-stick injury
- Partner is HIV-positive or status unknown
