PrEP (Pre-Exposure Prophylaxis) is the term used for HIV medication taken before sex to reduce the risk of HIV infection. This is not currently provided on the NHS outside clinical trials, but SHiP Derriford Hospital can provide information on whether you may benefit from PrEP, how to access PrEP medication and advice on safety monitoring whilst taking it.

PrEP medication is not currently available on the NHS. Many people buy their PrEP from reputable online retailers, such as Please get in touch with us if you would like to discuss routine monitoring tests if you decide to access PrEP via this route. We strongly advise against obtaining PrEP from unlicensed vendors, either online or in person.

We are sorry but the treatment spaces allocated for the National PrEP trial, IMPACT, are now full.

PrEP is not the same as PEP (Post-Exposure Prophylaxis) which is HIV medication that can be taken within 72 hours after sex to prevent becoming infected with HIV infection.
