What every medicine page answers
Every page lists its sources and the date they were last checked. How we build our pages →
Plain-English explainers on Thai medicine rules, written from official sources.
The 30-day personal-use rule, what paperwork to carry, and which medicines need a permit.
LawHow Thai narcotic and psychotropic categories work, and what each means for patients.
CannabisWeed, THC and CBD rules in 2026: prescriptions, tourists, bringing products in, and the new medical-only bill.
PharmaciesWhat pharmacies can sell over the counter, and when you need to see a doctor.
How-toLook up a registration number, Thai trade name or active ingredient yourself.
For most ordinary medicines, yes. The Thai FDA allows travellers to bring a quantity for personal use of up to 30 days, in the original packaging, with the prescription or a doctor’s letter. Psychotropic medicines need a Thai FDA permit for more than 30 days’ supply, narcotic medicines always need one, and Category 1 substances are not allowed at all.
Search the medicine or its active ingredient on DrugsThailand. Each page shows whether the ingredient appears in a Thai narcotic or psychotropic category, what that category means, and links to the official Thai FDA traveller permit service.
Some medicines are sold by pharmacists without a prescription, while others must be dispensed against a doctor’s prescription, and controlled medicines are tightly restricted. Each medicine page shows the Thai classification so you know what to expect.
Registration details come from the Thai FDA’s public medicine database, which records Thai and English trade names, active ingredients, registration numbers and licence holders. Controlled status comes from the Thai FDA Narcotics Control Division. Every page lists its sources and when they were last checked.
Not always. The same active ingredient is often sold under a different brand in Thailand. Search by active ingredient (for example semaglutide rather than Ozempic) to see every Thai registered product that contains it.
