- If the encounter was within 72 hours, go for PEP today. Don't wait to return home.
- Hospital emergency departments and sexual health clinics in Thailand can assess you.
- Ask for a written prescription and enough medicine to continue the course.
- Online guidance can help you decide quickly and plan follow-up.
You're still in Thailand. Last night didn't go as planned: the condom broke, slipped, or wasn't used. Now you're lying in a hotel room or apartment, heart racing, wondering what to do. The good news is that if you act quickly, you have an effective option, and Thailand is one of the best places in the region to get it.
This guide is for people who are still in Thailand. If you've already returned to India, see our guide on what to do once you're home.
Step 1: Count the Hours
PEP (Post-Exposure Prophylaxis) must be started within 72 hours of exposure, and it works best the sooner it begins. If you're within that window, today is the day to act. Don't wait for your flight home, the weekend to end, or symptoms to appear. Read more about why every hour matters.
Step 2: Go to the Right Place
Hospital emergency departments
Large public and private hospitals across Bangkok, Pattaya, Phuket, Chiang Mai and other cities can assess you at any hour and start PEP. Private hospitals often have English-speaking staff and international patient services.
Sexual health and HIV clinics
In Bangkok, the Thai Red Cross Anonymous Clinic offers HIV testing, PEP and PrEP. Private sexual health clinics in tourist areas also provide same-day PEP.
Late at night?
Go to a hospital emergency department. Don't wait for a clinic to open in the morning if the hours are running out.
Step 3: What to Say and Expect
You don't need to give a long explanation. Say: "I need assessment for PEP after a possible HIV exposure," and give the time it happened. Expect:
- Questions about the type of contact and timing.
- A rapid HIV test and possibly other blood tests.
- A prescription for a 28-day PEP course if appropriate.
- Advice on side effects and follow-up testing.
Not every encounter needs PEP. Oral sex and protected sex with an intact condom, for example, usually carry very low risk. If you're unsure, our guide on assessing your real HIV risk explains the factors.
Step 4: Take Your Plan With You
Before leaving the clinic, make sure you have:
- A written prescription with the exact medicine names.
- Enough tablets to reach home, or ideally the full course.
- Copies of any test results.
- Advice on when to have follow-up tests.
Keep medicine in your hand luggage when flying.
Step 5: Take Care of Yourself
- Take each dose at the same time every day.
- Avoid sex, or use condoms consistently, until follow-up testing is complete.
- Limit alcohol, which makes missed doses more likely.
- Rest and eat well; mild side effects usually settle.
Our article on PEP side effects offers practical tips.
Don't Forget STDs
PEP prevents HIV but not other infections like gonorrhoea, chlamydia or syphilis. Plan STD testing after about two weeks for gonorrhoea and chlamydia and at about six weeks for syphilis, alongside HIV follow-up tests.
If You're Travelling Onward
If you're moving to another country before returning home, check that you can carry PEP medicines legally, keep them in original packaging with the prescription, and know where you could obtain more if needed. Set your dose alarm to a consistent time, adjusting gradually across time zones.
Dealing With the Panic
Fear, guilt and racing thoughts are normal. Focus on what you can control right now: getting to care, starting PEP if advised, and following the plan. Once PEP is started, many people feel the panic ease.
How We Can Help From India
Dr. Yuvraj Monga can help you decide quickly whether PEP is likely to be needed and where to go, through an online consultation. If you start PEP in Thailand and return to India, he can continue your care: reviewing your regimen, arranging supply in India, managing side effects and planning follow-up tests.
Act Now, Worry Less Later
The hours after a risky encounter matter more than any others. Getting assessed today is the single most effective thing you can do for your health. Act first, and let the worry be handled with support afterwards.
Frequently Asked Questions
What should I say at the hospital?
Simply say you need assessment for PEP after a possible HIV exposure, and give the time it happened. Staff are used to this request.
Do I need to stay in Thailand for 28 days?
No. You can start PEP in Thailand and continue the course after returning home, as long as you have enough medicine and follow-up arranged.
How much does PEP cost in Thailand?
Costs vary widely between public and private facilities. Ask the clinic before treatment if cost is a concern, but don't let cost delay you.
