PEP (post exposure prophylaxis) The Eddystone Trust

What is PEP?


If administered within 72 it could stop you – or someone you’ve had sex with – getting HIV after possible exposure to the virus (unsafe sex or if a condom breaks). 

How do I take it?

PEP is a 28-day course of anti-HIV drugs that work to prevent the virus from entering cells in the body, thus halting infection. It is not a cure for HIV.

It isn’t 100% effective and the longer you leave it the less effective it is, so it is important to take it as soon as possible after possible exposure. 

What do I need to do to take it?

There are certain criteria for who can be prescribed PEP, and it is only a doctor who can make the final decision whether a person meets the criteria or not.

The main one is whether it has been less than 72 hours since possible exposure to HIV. After 72 hours PEP will not be prescribed.

An HIV test will be required both before and after the course of treatment. 

Remember PEP won’t protect you from all the other STIs or an unwanted pregnancy, using condoms remains the most effective method for protecting yourself against these.

It’s important if you go for regular STI screenings.
