PEP (Post-Exposure Prophylaxis) is emergency medication that can stop HIV after it’s entered your body. But timing is everything—you must start it within 72 hours (3 days) of possible exposure. The sooner, the better.
PEP is free from NHS sexual health clinics and hospital A&E departments. Find your nearest clinic here, and if clinics are closed, go to A&E—don’t wait.
PEP is for emergencies. If you’re having sex that puts you at risk of HIV more than once, PrEP might be a better option. Learn whether PrEP might be right for you.
