About HIV PrEP Samui

About us: HIV prevention on Koh Samui, at any hour

HIV PrEP Samui is the HIV prevention and testing service of a 24-hour medical clinic in Chaweng. We started it because worry does not keep office hours, and on an island many people are only here for a few days.

How we work

Three promises behind every visit

Any hour, same care

A licensed doctor is on site day and night, so a 3am visit is never a rushed one.

Only what is needed

We ask what matters medically and nothing more. A first name is enough to start.

Straight answers

Clear explanations of PEP, PrEP and test results, including what a result cannot tell you yet.

Who we see

Holidaymakers, island hoppers, long-stayers and locals

Many of the people we help are visitors: couples on holiday, backpackers coming over from Koh Phangan and Koh Tao, divers, and remote workers staying for a season. Others live and work on Samui.

Whoever you are, the approach is the same: no judgement, no unnecessary questions, and a plan that fits the time you have on the island.

Our care follows current HIV prevention guidance for PEP, PrEP and testing, and every page on this site is reviewed by our medical lead.
