PEP stands for Post-Exposure Prophylaxis. Post means ‘after’ and prophylaxis means ‘prevention’. PEP is a month-long course of anti-HIV medication that can prevent HIV from taking hold in the body. PEP needs to be commenced within 72 hours of a possible exposure to HIV to protect against infection.

If someone you know has been exposed to HIV in the past 72 hours call 1800 887 889 or visit for the location of a clinic that can assess your need for PEP.

PEP is free if you have had a medium or high-risk possible exposure to HIV.
