Post exposure prophylaxis (PEP)

Post exposure prophylaxis (PEP)


Post exposure prophylaxis (PEP) for HIV PEP is available and free for people who feel that they have been at high risk of exposure to HIV for example unprotected anal sex between men when their HIV status is not known.

PEP is a course of anti HIV medication taken twice a day for 28 days in order to prevent the HIV virus entering the body’s blood cells. If you are not sure whether you need PEP please speak to one of our team so we can assess the risk and advise you further.

PEP is available from our Sexual Health clinics in Crawley, Chichester and Worthing during opening hours. Outside of these hours you should attend your local A&E department.


Pre Exposure Prophylaxis (PrEP) is taking a tablet every day or on demand before and after sex to prevent you getting HIV.  

PrEP has been shown to be highly effective in studies in gay men. It is NOT currently available on the NHS (this means we cannot prescribe this for you).

PrEP is available from other sources (online) and there is information available to help support you in deciding whether this is right for you (see links).

It’s really important that if you’re on PrEP you have regular monitoring (blood tests and urine tests). We recommend you make an appointment to discuss this with a doctor at one of our clinics who can advise you further. We recommend HIV testing and STI screening every 12 weeks.
