Post exposure prophylaxis (PEP)

What is HIV post exposure prophylaxis (PEP)?

HIV post exposure prophylaxis (PEP) is a course of HIV medication that aims to prevent HIV infection following a recent exposure to HIV, such as condomless sex, sharing needles or pricking yourself with an infected needle.

PEP must be started within 72 hours (3 days and nights) after a possible exposure to HIV, and sooner if possible. 

A full course of PEP is for 28 days (4 weeks).

Where do I get PEP?

PEP is available in many STI clinics. If it is not possible to get PEP from your STI clinic within 72 hours, PEP can be accessed in a number of emergency departments.
