Post Exposure Prophylaxis (PEP) is an anti-HIV medication that is prescribed to a HIV negative person within 72 hours of potential exposure to HIV. Ideally it should be started within 24 hours. It needs to be taken for 28 days. A&E departments are able to start PEP when the clinic is closed.
PEP is recommended if there is a greater than 1 in 1000 chance of catching HIV. PEP is not recommended for human bites, discarded needlestick injury, or oral sex. For other situations we offer a discussion of risks versus benefits for taking PEP. Please call our central booking line on 01904 721111 or attend Q&W8 within 72 hours of potential exposure to HIV. See our clinics and services page for Q&W8 times.
PEP is more effective the sooner it is taken, so please attend the clinic or A&E as soon as possible for a discussion if you think you need it.
