Pharmaceutical Regulation in Thailand: The Overview

TL;DR

Thai pharmaceutical regulation centres on the Drug Act B.E. 2510 (1967) (modern drugs), Traditional Medicine Act B.E. 2542 (1999), the Narcotics Code B.E. 2564 (2021), and the Psychotropic Substance Act B.E. 2518 (1975). The Food and Drug Administration (FDA-Thai, MoPH) handles registration, manufacturing GMP, import licensing, and pharmacovigilance. Pharmacist supervision is required at retail pharmacies under the Pharmacy Profession Act B.E. 2537 (1994).

FAQs

1. Online pharmacy legal in Thailand?

Only with valid pharmacy licence + pharmacist present + drug-class compliance; recent FDA notifications add e-commerce-specific rules.

The Regulatory Framework

Medicines in Thailand are regulated by the Thai Food and Drug Administration (FDA) under the Ministry of Public Health, primarily through the Drug Act B.E. 2510 (1967) and its amendments. A product must be registered (granted a marketing authorisation) before it can be manufactured, imported or sold, and the business needs the appropriate licence for each activity — manufacture, import, or sale. Drugs are classified by control level — for example dangerous drugs (พ.ร.บ. ยา categories requiring a pharmacist), specially-controlled drugs (prescription-only), and household remedies that can be sold more freely — and the classification drives who may dispense the product and under what conditions.

Licensing and Compliance

A modern pharmacy generally needs a valid sale licence with a pharmacist physically present during operating hours, and must observe the rules for its drug classes; recent FDA notifications extend controls to online sale of medicines. Manufacturers and importers must meet Good Manufacturing Practice (GMP) and post-marketing obligations including adverse-event reporting, and advertising of drugs to the public is tightly restricted and requires prior approval. Non-compliance — selling unregistered or misclassified products, operating without a licence, or advertising without approval — carries fines and imprisonment, and the FDA can suspend or revoke licences and order recalls.

2. Can I import medicine for personal use?

Small quantities of prescribed medicine for personal use are generally tolerated with supporting documentation, but controlled substances and unregistered products are restricted — check the current FDA and Narcotics Control rules before travelling.
