Emergency contraception

Emergency contraception can be used to help reduce the risk of pregnancy after unprotected sex, although it must be used within 5 days. The most effective method is the emergency IUD (copper coil).

If you have had unprotected sex and are not using a regular method of contraception, or if you have had a problem with your regular method (eg missed pill, broken condom), we would recommend you attend a walk-in clinic to discuss emergency contraception. Please call the clinic on 020 8321 5718 for advice if you are unable to attend the walk-in.

Out of hours, you can access emergency contraception from most local pharmacies or you can attend your nearest A&E/Urgent Care Centre. 

Post Exposure Prophylaxis (PEP)

Post Exposure Prophylaxis (PEP) is medication used following potential exposure to HIV. PEP should be started as soon as possible after a potential risk, ideally within 24 hours but within a maximum of 72 hours. 

If you think you need PEP, please call us Mon–Fri on 020 8321 5718. Out of hours, you can call NHS 111 for advice or go to your nearest A&E/Urgent Care Centre for PEP.
