Importing Medicines into Thailand: FDA Personal-Use Rules
Personal-use medication import is permitted up to 30-day supply with prescription. Larger quantities require FDA permit. Controlled substances face strict rules under the Narcotics Code B.E. 2564.
TL;DR
Personal-use medication import is permitted up to a 30-day supply per traveller with the original prescription under Drug Act B.E. 2510 (1967) and FDA-Thai Notifications. Larger quantities require an FDA-Thai import permit. Controlled substances (narcotics, psychotropics) face strict rules under the Narcotics Code B.E. 2564 (2021) and Psychotropic Substance Act — prior FDA permission and import-quota system apply.

FAQs
