Getting a prescription in Thailand as a foreigner

Every case is different. This guide reflects the situation as of 13 November 2026. A Thai doctor decides what to prescribe, and controlled medicines are handled more strictly than everyday ones.

Does a foreign prescription work?

Not on its own. A prescription from home helps a Thai doctor or pharmacist see what you normally take, but it is not a Thai prescription. For anything controlled or specialist, expect a local consultation first.

Where to go

• Private hospitals in Bangkok, Phuket, Chiang Mai and Pattaya have international departments, English-speaking doctors and their own pharmacies. They are the easiest option for repeat prescriptions and controlled medicines, but the most expensive.
• Private clinics are cheaper and fine for common conditions.
• Government hospitals cost less again, but expect longer waits and less English.
• Telemedicine. Licensed Thai clinics and hospitals can diagnose you and issue an electronic prescription over video, and a licensed pharmacy can dispense and deliver the medicine.

What to bring

• Your passport
• Your current medicine in its packaging, or clear photos of the label
• Your prescription or a letter from your doctor, with the generic name, strength and dose
• Recent test results for chronic conditions, if you have them

Controlled medicines

Strong painkillers, benzodiazepines, ADHD medicines and some others are usually only prescribed by hospital doctors, often after a full assessment. Do not count on getting them quickly. If you depend on one, plan your supply before you travel, using our guide to bringing medicine into Thailand.

Taking a Thai-prescribed narcotic home

If a Thai doctor prescribes you a narcotic medicine and you want to take it out of Thailand, you need a separate Thai FDA permit. See leaving Thailand with medicine.
