PEP — Emergency HIV Prevention
Time-critical. If you may have been exposed, come now, not tomorrow.
About this test
PEP is a 28-day course of HIV medication started after a possible exposure, to stop an infection taking hold. It has a hard deadline: it must begin within 72 hours of the exposure, and the sooner within that window it starts, the better it works. After 72 hours it is no longer offered, because it no longer does what it is for. That deadline is the entire reason this page is short — if you think this applies to you, call the clinic now and read the rest afterwards.
Who should get this test
- Anyone who has had condomless sex with someone whose HIV status they do not know
- Anyone whose condom broke or slipped with a partner living with HIV who is not virally suppressed
- Anyone who has shared injecting equipment
- Anyone who has been sexually assaulted — you do not need to have decided anything else to start PEP
- Healthcare workers after a needlestick or similar injury
When to get tested
- Within 72 hours of the exposure, and as close to it as you can manage. This is the whole of the advice.
- A baseline HIV test is done before starting — PEP is for people who do not already have HIV.
- Follow-up testing is scheduled after the course finishes. The doctor sets the intervals.
Preparation
- Do not wait for an appointment slot. Call, or come in — this is the one service where walking in is the right move.
- Bring anything you know about the exposure: when it happened, and what you know of the other person's status or treatment.
- Expect a blood draw before you start, and expect to be here around 45 minutes.
