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 is looking at ways to provide it to patients who cannot get onto a trial. Please check this page for updates, or call us to discuss.

In the meantime, we can provide information on whether you may benefit from PrEP, how to access PrEP medication and advice on safety monitoring whilst taking it. Please call us to discuss.

Because PrEP medication is not currently available on the NHS, many people buy their PrEP from reputable online retailers, such as We strongly advise against obtaining PrEP from any other unlicensed vendors, either online or in person. Another source of information on PrEP is

The Terrence Higgins Trust has set up the Mags Portman fund to support those who need PrEP but can’t afford to buy it themselves. They provide voucher codes that can be used to order PrEP online free of charge.

Please get in touch with us if you are taking or want to take PrEP. We can help you decide if PrEP is right for you, and offer you the necessary 3-monthly monitoring tests, free of charge.

The treatment spaces allocated for the National PrEP trial, IMPACT, are now full. However, please get in touch with us if you would like to go on the waiting list.

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.
