Leaving Thailand with medicine: permits, limits and your next country
What you need to take medicine bought or prescribed in Thailand out of the country, including the Thai FDA OC-2 permit for narcotics.
Updated 13 November 2026
Check both ends. Thailand's exit rules are only half the picture. Your next country decides what you can bring in. This guide reflects Thai guidance as of 13 November 2026.
Narcotic medicines prescribed in Thailand
If a Thai doctor treated you with a narcotic medicine (Schedule II or III, such as morphine, oxycodone or codeine products) and you want to take it with you, you need a Thai FDA permit, Form OC-2, before you leave.
- Apply online at permitfortraveler.fda.moph.go.th at least two weeks before departure.
- The permit also covers any leftover medicine if you bring it back to Thailand.
- Carry the printed permit or the file on your phone, with the medicine and your medical documents.
Psychotropic medicines
For psychotropic medicines in Schedules 2, 3 and 4, such as many benzodiazepines, Thai FDA guidance allows up to 30 days of prescribed use when you leave, with no permit.
Ordinary medicines
Keep them in their labelled packaging with your Thai prescription or receipt. A medicine you bought without a prescription in Thailand may need one where you are going.
Your destination and transit stops
Many countries treat medicines differently from Thailand. Some, including several in the Middle East and Asia, require advance approval for controlled medicines or ban some entirely. Check the official rules for every country you will pass through.
