01 — The short answer
Buying PrEP in Thailand: prescription first.
If you want to buy PrEP in Thailand, you need a doctor’s prescription, so the pharmacy counter is not the place to start.
PrEP is a daily or event-based tablet, usually tenofovir with emtricitabine, that greatly lowers your chance of getting HIV. Because it is an HIV medicine, Thai rules route it through clinics, hospitals and licensed online doctors. The legal route is quick, affordable and gives you a supply you can rely on month after month.
This guide covers why tests come first, how the routes compare, what to check before you order online and how to plan refills. For dosing and first-visit details, see our main guide to PrEP in Pattaya.
02 — Why a prescription
Three checks that come before the pills.
You take PrEP for months or years, so a doctor first confirms it is safe for you. Three checks matter most:
- A negative HIV test. PrEP contains two drugs, which is not enough to treat HIV. If someone already has HIV without knowing it, taking only these two can let the virus become resistant, which narrows future treatment options.
- Kidney function. Tenofovir leaves the body through the kidneys, so a simple blood test at the start, and later as advised, keeps an eye on them.
- Hepatitis B status. Both PrEP drugs also act on hepatitis B. For people who carry it, stopping suddenly can trigger a flare, and the on-demand schedule is not suitable.
None of these checks is slow. At a clinic they usually happen in the same visit as your prescription, and you leave with your first bottle. The HIV test is then repeated about every three months; see HIV testing in Pattaya for how that works.
03 — The reality
What happens at a Thai pharmacy counter.
Many medicines are easy to buy across the counter in Thailand, so it is natural to assume a PrEP pill in Thailand works the same way. It doesn’t: antiretrovirals are meant to be supplied through hospitals and clinics on prescription.
In practice, rules are not always followed. A peer-reviewed survey of generic HIV medicines in Thailand and Vietnam found that researchers could obtain some of them from private drug stores with no prescription.
If a PrEP Thailand pharmacy sale does happen, here is what you miss:
- No HIV test, so an existing infection could go unnoticed and turn resistant.
- No kidney or hepatitis B checks, so nobody spots a reason to adjust or avoid the medicine.
- No 3-monthly reviews, which is where problems are caught early.
- No way to check the product, its expiry date or how it was stored.
04 — Your options
Four routes to PrEP and how they differ.
Clinics and licensed online doctors are the two routes that combine a legal prescription with ongoing care.
Ways to get PrEP in Thailand compared
| Route | Tests included | Ongoing supply |
|---|---|---|
| Private sexual health clinic | HIV, kidney and hepatitis B at the first visit | Refills at 3-monthly reviews |
| Hospital | Yes, often through an outpatient department | Possible, but appointments can be slow |
| Licensed telemedicine | Arranged with a lab or partner clinic | Delivered after each review |
| Pharmacy counter or unverified website | None | Whatever you can find each time |
For most people in Pattaya, a clinic visit is simplest: tests, prescription and tablets in one place. Our page on our HIV prevention services shows how PrEP sits alongside testing and STI checks.
05 — What’s in the bottle
Generic or branded: does it matter?
Thailand makes and registers its own generic PrEP tablets in Thailand, and they are widely used. The best-known, Teno-EM, is made by the state-owned Government Pharmaceutical Organization and contains the same two ingredients at the same strengths as Truvada. A bioequivalence study found it is absorbed in the same way as the original.
According to PrEPWatch’s Thailand country profile, oral tenofovir/emtricitabine PrEP was approved in Thailand in 2016, and generic versions are approved as well.
Generic vs branded PrEP
| Point | Thai generic | Branded (e.g. Truvada) |
|---|---|---|
| Active ingredients | Tenofovir disoproxil and emtricitabine | The same |
| Protection | Equivalent when taken as advised | Equivalent when taken as advised |
| Cost | Lower | Higher |
| Where to get it | Clinics, hospitals, licensed online doctors | Mainly private clinics and hospitals |
The quality question is less about generic versus branded and more about where the bottle came from. A registered product dispensed by a clinic has a batch number, an expiry date and a traceable supplier. The same name on a parcel from an unknown seller tells you very little.
06 — Ordering online
Buying PrEP online: the honest trade-offs.
You can buy PrEP online in Thailand legally, as long as a licensed Thai doctor reviews you and prescribes. Many people find PrEP online in Thailand handy for refills once they have been seen in person. The problem is sites that skip the doctor entirely.
Pros and cons of buying PrEP online
| Aspect | Upside | Downside |
|---|---|---|
| Convenience | Refills delivered to your door | Delivery delays can leave you short |
| Privacy | No waiting room | Unclear who handles your data on some sites |
| Medical checks | Good services book lab tests for you | Poor ones never ask for results |
| Product | Licensed pharmacies dispense registered stock | Unverified sellers may ship expired or fake tablets |
Before you pay, check for these signs of a proper service:
- A named, licensed doctor reviews you before anything ships.
- Recent test results are required, including HIV, kidney function and hepatitis B.
- A 3-monthly HIV test is built in before each new supply.
- Packs arrive sealed and labelled with your name, dose and expiry date.
07 — Staying supplied
Keeping your PrEP tablets going without gaps.
The goal is not a single purchase but a steady rhythm of tests and refills.
Clinics usually hand over one to three months of PrEP tablets in Thailand per visit, depending on your results and the doctor’s judgement. After that, each refill is linked to a fresh HIV test.
Your PrEP supply plan
| Stage | What happens | Typical supply |
|---|---|---|
| First visit | Consultation, HIV, kidney and hepatitis B tests | One to three months |
| Around month one | Optional check-in on side effects | Continue your bottle |
| Every 3 months | HIV test, STI screen, kidney check as advised | Next one to three months |
| Before long travel | Review and paperwork for customs | Enough for your trip, as agreed |
Set a reminder two weeks before your bottle runs low. If you run out and then have condomless sex, don’t wait for the next refill: check the 72-hour PEP window, because PEP may be needed.
08 — Trips and home
Buying for a trip or to take home.
Some visitors want to buy PrEP in Thailand because it costs less than at home. That is fine when it comes with a prescription, a test record and packs in their original labelled boxes. Our guide to taking PrEP to Thailand covers carrying tablets through customs and the limits on personal medicine.
Approximate private prices are listed on our PrEP page, and we confirm the full cost before you start. If you’re still deciding between medicines, our comparison of PEP vs PrEP for travellers helps. The same prescription logic applies to emergency treatment, as explained in can you buy PEP at a pharmacy.

Questions
Buying PrEP: quick answers.
Written by the HIV PEP Pattaya team, based on WHO and PrEPWatch guidance. Last updated 29 September 2026.
Is PrEP over the counter in Thailand?
No. It is a prescription medicine supplied through clinics, hospitals and licensed online doctors after an HIV test and a few safety checks.
Can I buy Truvada at a Thai pharmacy?
Not legally without a prescription. Most people in Thailand use registered generic versions with the same ingredients, prescribed by a doctor.
Are generic PrEP pills safe?
Registered Thai generics contain the same drugs as Truvada and work the same way. The risk lies with unknown sellers, where you can’t check storage, expiry or authenticity.
Can I buy a 3-month supply of PrEP?
Often, yes. Clinics commonly give one to three months per visit, depending on your test results and the doctor’s assessment.
Can I order PrEP online in Thailand?
Yes, through licensed telemedicine that reviews your test results. Avoid sites that ship tablets without asking about your HIV status.
