What is PEP for HIV?

PEP or Post PEP or Post Exposure Prophylaxis for HIV is a most effective HIV prevention strategy following a high risk exposure or potential exposure to HIV. Post exposure prophylaxis is to be started within 72 hours of possible exposure to HIV. Doctors recommend to start PEP as early as possible after the exposure for best results. PEP is highly effective in lowering the risk of HIV transmission, if taken correctly and consistently for 28 days.
