PEP (Post-Exposure Prophylaxis) 

PEP (Post-exposure prophylaxis) is a 4-week course of anti-HIV medication that is shown to be effective in preventing HIV infection if started within 72 hours of exposure.

The key to PEP is accessing it as soon as possible after you think you may been exposed to HIV. PEP is most effective within up to 24 hours of exposure and unlikely to work if not taken within 72 hours (three days) of the suspected exposure to HIV.

If you believe you have been exposed to HIV, or have exposed someone to HIV, access PEP from local sexual health clinic, hospital emergency department or go to http://www.getpep.info/ for more information.
