Yes, you can get PrEP in Thailand, and visitors do it every day. It is legal, widely used and prescribed by doctors at sexual health clinics and hospitals after a quick HIV test and a couple of safety checks.
The hard part is not finding PrEP. It is knowing which route fits your trip, what to bring and how to keep taking it once you fly home. This guide is the map; each section links to a deeper page when you need more detail.
Is PrEP available and legal in Thailand?
PrEP is fully legal in Thailand. According to PrEPWatch's Thailand country profile, oral PrEP was approved in 2016, and Thailand now also makes its own generic versions.
Thailand is often held up as a regional leader in HIV prevention. Thai nationals can get PrEP through the national health scheme, while visitors and most expats use private clinics and pay for their own care.
This fits World Health Organization guidance on PrEP, which recommends offering it to anyone at substantial risk of HIV. In practice, that means you don't need to justify yourself to a Thai doctor; wanting the protection is reason enough.
Do Thai pharmacies sell PrEP over the counter?
PrEP is a prescription medicine, so the pharmacy counter is the wrong place to start. Even if a shop offers you a box, you would skip the HIV test that makes PrEP safe to take.
If you have HIV without knowing it, PrEP alone is not enough to treat it, and the virus can become resistant. That is why every proper PrEP clinic in Thailand tests first.
Three ways visitors get PrEP in Thailand
Most people fall into one of three groups. Your best route depends on whether you already use PrEP and how long you are staying.
Which route fits your situation
| Your situation | Best route | Main thing to plan |
|---|---|---|
| Already on PrEP at home | Bring your own supply | Enough pills plus spare days |
| New to PrEP, short trip | Start at a clinic on arrival | Time for protection to build |
| Staying months or living here | Local clinic with regular refills | A visit every 3 months |
| Ran out while travelling | Clinic visit for a new supply | An HIV test before restarting |
If you are already a PrEP user, our guide to taking PrEP on your Thailand trip covers timing and how many pills to pack.
If you are new to it, start with what PrEP is and how it works. It takes about two minutes to read and makes the first visit easier.
What happens at your first PrEP visit
A first PrEP visit in Thailand is short and practical. You talk to a doctor, have a few tests and, if everything is fine, leave with a prescription and your first supply.
The checks a doctor will want
- HIV test. It must be negative before you start.
- Kidney function. A simple blood test, because the medicine leaves the body through the kidneys.
- Hepatitis B. This affects which schedules are safe for you.
- STI screen. Recommended, because PrEP does not prevent other STIs.
You can read more about each one in our page on the tests you need before starting PrEP. A doctor will assess your situation and explain the results in plain language.
What to bring with you
- Your passport or another photo ID.
- A list of any medicines you take, including hormones such as oestradiol.
- Recent test results, if you have them from home.
- Your rough travel dates, so the doctor can plan your supply.
How long it takes
Most first visits are done in under an hour, including the tests. Some results come back quickly, while others, such as kidney function, may follow later; the doctor will tell you how they handle that.
Being honest about your sex life and plans helps the doctor choose the right schedule. Nothing you say is shared, and nobody is there to judge.
Daily or on-demand: which schedule?
There are two ways to take oral PrEP. Daily PrEP suits everyone, while on-demand 2-1-1 is an option only for some people having anal sex.
Daily vs 2-1-1 at a glance
| Point | Daily PrEP | On-demand 2-1-1 |
|---|---|---|
| Who it suits | Anyone | Anal sex only |
| Not suitable for | — | Hepatitis B, oestradiol users |
| How you take it | One pill every day | Double dose 2–24 h before sex, then 1 + 1 |
| When protection peaks | About 7 days (anal), 21 days (vaginal or front-hole) | From the double dose, if timed right |
Our guide to how long PrEP takes to work explains these timings in detail. You can also put your own dates into the PrEP planner to see exactly when you reach day 7 or day 21.
Costs, brands and how much you can take home
We don't list prices in this guide, because they depend on a few things. These include the tests you need, whether you choose a Thai generic or a branded medicine, and how many months of supply you take.
For current costs, see our PrEP prices in Pattaya page. Thai generics contain the same active ingredients as branded PrEP; our guide to PrEP brands available in Thailand compares them.
Taking a supply home
Many visitors ask for a few months of PrEP to take home. Doctors usually supply up to the next 3-monthly check, because each refill should follow a fresh HIV test.
Before you leave, check your home country's rules on bringing in personal medicines. Keep the pills in their labelled packs with your prescription.
After you fly home
PrEP works best as an ongoing routine, not a holiday extra. When you get home, book in with a local sexual health service before your Thai supply runs out, and take your Thai test results with you.
If you plan to stop, ask your doctor how long to continue after your last sex. People with hepatitis B should never stop PrEP without medical advice.
Getting PrEP in Pattaya
Pattaya is an easy place to start PrEP. Many people combine a clinic visit with a beach day in Jomtien or a quiet morning in Naklua, and the whole thing fits into one short appointment.
Our step-by-step guide to getting PrEP in Pattaya walks you through the visit, and the HIV PrEP Pattaya homepage has an overview of what we offer. If you only need a check, see our page on HIV testing in Pattaya.
One thing PrEP cannot do is protect you after the fact. If you may have been exposed to HIV in the last 72 hours, you need PEP, not PrEP, and you should act today.

Frequently asked questions
Can you buy PrEP in Thailand without a prescription?
You shouldn't. PrEP is a prescription medicine, and the HIV test that comes with a prescription is what keeps it safe and effective.
Is PrEP common in Thailand?
Yes. Thailand has offered PrEP since 2016 and has a well-established network of clinics, hospitals and community services that prescribe it.
Can tourists get PrEP in Thailand?
Yes. Visitors can see a doctor at a private clinic, have the start-up tests and leave with a supply, usually in a single visit.
Does PrEP protect against other STIs?
No. PrEP only lowers the risk of HIV, so condoms and regular STI checks still matter.
How often do I need check-ups on PrEP?
Every 3 months. Each follow-up includes an HIV test, and kidney checks are repeated as your doctor advises.
