What is HIV post-exposure prevention (PEP)?
HIV post-exposure prophylaxis (PEP) is treatment with medicine. If you've had contact with HIV, this treatment can help prevent the virus from taking hold and spreading in your body. PEP is only for people who've been exposed but aren't yet infected. It must be started no later than 3 days after exposure.
How is HIV post-exposure prevention (PEP) given?
PEP must be started within 3 days (72 hours) after you've been exposed to HIV. Your doctor will do an HIV test to be sure you're not already infected. You may get other tests. You'll take the PEP medicine for 28 days. You'll get another HIV test at the end of your treatment.
