If there's a possibility of HIV exposure from a high-risk source, you may need PEP within 72 hours — please call NHS 111, go to the Ambrose King Centre (Royal London Hospital, Mount Terrace, E1 2BB) or A&E if it's out of hours. PEP is most effective the sooner it's started. We don't provide PEP at this clinic.
For testing — you can't reliably test in the first few days. We'd typically advise testing for chlamydia/gonorrhoea at 2 weeks, HIV at 4–6 weeks, syphilis at 6–12 weeks. Symptoms appearing earlier (discharge, ulcer, rash) warrant immediate consultation — come in.
If you've been sexually assaulted, please contact The Havens (Sexual Assault Referral Centre) — 020 3299 6900 — they provide free specialist care including HIV PEP, emergency contraception, forensic examination and psychological support. You don't have to involve the police.
