The fastest way to get PEP

If you had a possible HIV exposure in the last 72 hours, don’t wait for a reply before setting off. Come straight to the clinic: walk-ins are welcome for PEP, and most people take their first dose within about an hour of arriving.

If you would like to check something first, LINE or WhatsApp is usually the quickest way to reach us, and you can also call. Use the booking form above for PrEP, HIV testing or STI screening, or if you prefer to plan a time. Not sure whether you need PEP at all? Our guide to HIV risk and whether you need PEP can help you decide.

What to bring

  • Your first name. No ID or passport is required.
  • A list of medicines you take, including vitamins, supplements and antacids, so the doctor can choose PEP medicines that are safe with them.
  • The date and time of the exposure, as accurately as you can, and any details you know about the other person’s HIV status or treatment.
  • Your phone, so we can send you follow-up test reminders if you would like them.

What happens after you message or book

  1. We reply and answer any quick questions. You don’t need to explain everything in writing; a short message is fine.
  2. You come in. You’ll be shown to a private room.
  3. You see a doctor. An English- or Thai-speaking doctor talks through what happened and arranges any tests.
  4. You leave with a plan, whether that is a PEP course, PrEP, test results or treatment. See our PEP, PrEP, HIV and STI testing services for what each visit includes.

While you are on your way, our guide to what to do after a possible HIV exposure explains the next steps calmly.

Getting here by BTS or MRT

The clinic is in the Sukhumvit area, near BTS Asok and MRT Sukhumvit. Both stations are easy to reach by public transport from most parts of central Bangkok, and taking the train is often faster than a taxi at busy times. You can plan your journey with the BTS Skytrain route map and journey planner. For our exact location, use the map above.

Opening hours

We are open Monday to Sunday, 09:00–21:00, including weekends. If you need PEP outside these hours, go to a hospital emergency department rather than waiting until morning, then contact us for follow-up.

Our privacy promise

Everything you tell us stays confidential. Consultations take place in private rooms, you only need to give a first name, and anonymous HIV testing is available. There is no judgement here, only care.
