PrEP and PEP, in plain language

Sep 1

2 min read

PrEP is medicine you take to greatly reduce the chance of getting HIV if you are negative. PEP is a short emergency course after a possible exposure. Neither one is a personality. Neither one replaces talking, testing, or the rest of your sexual health. This is how gay and bisexual men can ask a clinic without theatre.

PrEP: before, not after

PrEP (pre-exposure prophylaxis) is for HIV-negative men. Daily pills are the most familiar form. In some places, on-demand (event-based) dosing is an option for anal sex if a clinician agrees it fits you. Long-acting injections exist in some health systems. What is licensed near you is a local fact, so ask rather than guess from a social-media thread.

PrEP is excellent at HIV and does nothing for gonorrhoea, chlamydia, syphilis, or hepatitis. You still need screens. You still need a kidney check and an HIV test before you start, because PrEP is not treatment.

PEP: the emergency course

PEP (post-exposure prophylaxis) is for after a risk: a broken condom, an assault, a weekend you cannot piece together, a partner whose status you learned too late. It works best when started as soon as possible. Ideally start it within 24 hours, and it must be started within 72 hours (3 days). It is a full course of HIV drugs, not a single pill at the club.

Go to emergency care or a sexual health clinic that does PEP. Do not wait for Monday because you are embarrassed. Embarrassment is not a virus. HIV can be.

How to ask

Say you are a man who has sex with men and you want PrEP or you think you need PEP. You do not owe a life story. You may be asked about last sex, condoms, other drugs, and partners. Answer enough that they can prescribe safely. If a clinician is hostile, that is their failure. Find the next clinic. Many cities have MSM-competent services even when the first GP does not.

Bring a list of other medicines. If you use party drugs, say so for interaction and safety reasons, not for a moral lecture. Chemsex: harm reduction without shame is the longer conversation.

Cost, access, and the rest of the stack

In some countries PrEP is free or cheap. In others it is a fight. Ask about generic, insurance, and sexual health programmes. PEP is time-critical. Do not lose hours comparing prices if emergency care can start you on it now.

PrEP sits next to U=U and testing, not in place of them. For a relationship in which one of you is positive, read When one of you is living with HIV. For appointments, use real clinics. For community, join Unite Gay Network.
