Use the generic name
Find the active ingredient on the pharmacy label or prescription. Enter that name into the Thai FDA checker and select the exact match.
Check before carrying
Taking medication
into Thailand.
Start with the active ingredient, current Thai classification and official instructions. A doctor’s letter is not sufficient in every case.
01
Search by active ingredient, not only brand name.
02
Some substances require prior permission and some are prohibited.
03
Never change prescribed treatment based on a travel article.
01
Identify the substance correctly
Thai rules apply to the active ingredient and its legal schedule, not the familiar US product name.
Check every medicine
Combination products can contain more than one active ingredient. Check each substance and do not assume an over-the-counter US medicine has the same status in Thailand.
Record dose and quantity
Keep the medicine name, strength, instructions, total quantity and intended number of days consistent with the medical documents.
Ask the authority when unclear
If the checker and guidance do not resolve the situation, contact the Thai FDA before travelling rather than relying on an online forum or retailer.
02
Understand the broad categories
The official Thai FDA summary sets different conditions for narcotics, psychotropic substances and other medicines.
Schedule I substances
The Thai FDA says import of Schedule I narcotics and Schedule I psychotropic substances is prohibited even when carried by a patient.
Schedule II narcotics
The Thai FDA says these may be carried for up to 90 days of use only when permission has been granted by the FDA.
Psychotropic Schedules II–IV
The official summary permits up to 30 days with the required medical certificate. Quantities from 31 to 90 days require Thai FDA permission.
Other prescription medicine
The Thai FDA says medicines outside the narcotic and psychotropic categories may be carried for 30 days of use and recommends a valid prescription or physician’s medical document.
03
Prepare the evidence
Correct documentation reduces ambiguity but does not turn a prohibited substance into a permitted one.
Original labelled packaging
Keep medicine in the pharmacy or manufacturer packaging that identifies the patient, medicine, strength and instructions.
Medical document
Ask the prescriber for a signed document that identifies the condition, medicine, dose, quantity and prescriber details in clear English.
Permit when required
Use the Thai FDA process early enough to resolve questions and obtain any required approval before flying.
Cabin-baggage plan
Keep essential medicine and documents accessible, while checking airline security rules for liquids, needles, batteries or refrigerated devices.
04
What the planner will not do
Medication is too important for a general travel form to issue a definitive clearance.
No diagnosis or substitute
The site does not advise changing, stopping or replacing prescribed treatment. Discuss clinical decisions with the prescriber.
No stored medicine name
The discovery-tour planner asks only whether a controlled-medicine check may be needed. It does not request or store a medication name.
No promise of local availability
Availability, brand names, strengths and dispensing requirements can differ. Plan continuity with the prescriber before departure.
No reliance on old lists
Use the current Thai FDA checker and guidance immediately before travel because classifications and procedures can change.
Primary sources
Verify before relying.
