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 to attend the clinic within 72 hours of potential exposure to HIV. See our clinics and services page for appointment 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.
