HIV PrEP (Pre Exposure Prophylaxis) is a treatment that provides protection from catching HIV. The medicine needs to be started before you have sex. It is more effective than condoms when taken correctly. However PrEP does not provide any protection against other sexually transmitted infections.

We’re here to help. If you’re taking PrEP, it’s really important to get the right advice, run some tests, check you don’t have Hepatitis B , make sure that any other drugs or supplements you take don’t interact with PrEP and that you don’t have any other health problems that might be an issue.

Watch the videos below before you make an appointment to start PrEP. We also recommend that you read this PrEP leaflet on the ‘i-Base’ website.
