What is PEP?
An emergency medicine that stops HIV before it takes hold
PEP (post-exposure prophylaxis) is a 28-day course of antiretroviral tablets taken after a possible exposure to HIV, such as condomless sex, a broken condom, sexual assault or a needle-stick injury. It works by stopping the virus from establishing infection in your body.

FAQ
Your questions, answered honestly
Can’t find what you need? Message us and a nurse will reply, usually within minutes.
How soon do I need to start PEP?
As soon as possible — ideally within a few hours, and no later than 72 hours after the possible exposure. The sooner PEP is started, the better it works. After 72 hours PEP is no longer recommended, but you should still get tested and advised.
How effective is PEP?
When started early and taken every day for the full 28 days, PEP greatly reduces the chance of HIV infection. It is not 100%, which is why daily adherence and follow-up testing matter.
What does the treatment involve?
A short consultation, a baseline HIV test (plus kidney and hepatitis B checks where needed), then a 28-day course of antiretroviral tablets, usually taken once or twice daily. You take your first dose at the clinic.
Are there side effects?
Modern PEP regimens are generally well tolerated. Some people have mild nausea, headache or tiredness in the first days, which usually settles. Your doctor will tell you what to watch for.
Is my visit confidential?
Yes. Your consultation and results are strictly confidential. You can register with a first name only, and nothing is shared with employers, embassies or insurers.
