PEP or Post-exposure prophylaxis can stop you from getting the human immunodeficiency virus (HIV) in an emergency situation. This medication is available in Ireland and you can use it after potential exposure to HIV, such as unprotected sex, sexual assault or a needle-stick injury.

The most important thing to remember about PEP is time is critical. You must start taking the medication as soon as possible, and no later than 72 hours (3 days) after the possible exposure. It’s a course of medication you take for 28 days (4 weeks) that works by preventing the virus from settling in your body.

If you think you might need PEP, a doctor or nurse needs to check you first. You can get this assessment at STI clinics or at hospital Emergency Departments (EDs) across Ireland. It’s usually best to go to an STI clinic if you can, and only use the ED if it’s a true emergency or if you can’t get to an STI clinic within that 72-hour window such as the weekend. If you think you’ve recently been exposed to HIV, you can find a list of STI clinics where PEP is available here.

Knowing about PEP, and acting quickly if needed, is an important part of protecting your health. PEP is free in Ireland.
