Pharmacies, prescriptions and medicines in Thailand
Pharmacies are easy to find in much of Thailand, but that does not mean every medicine from home is legal to bring in or suitable to replace your usual product. The rules for controlled medicines depend on the exact ingredient, and any Thai FDA permit needs to be arranged before you fly.

The short answer
How should a family plan medicines before moving to Thailand?
Thai FDA guidance allows ordinary finished medicines for personal use up to 30 days, in original containers with a prescription. Narcotic Schedule II/III medicines require an FDA permit and may be allowed up to a prescribed 90-day supply; psychotropic Schedule II–IV medicines need a certificate for up to 30 days and a permit for 31–90 days. Apply at least 15 days before travel where a permit is required and verify the exact ingredient in the official portal.
One record per person
Create a medicine record using active ingredients
A brand name alone may not identify the same medicine in another country. Keep this record with the original documents and a secure offline copy so border officials, doctors and pharmacists can understand the exact treatment.
Active ingredient
Use the generic/INN name—not only the brand used in your home country.
Strength + form
For example 5 mg tablet, 100 units/mL pen or 10 mg/5 mL liquid.
Dose + purpose
How, when and why it is taken, including child weight where relevant.
Legal category
Ordinary prescription, psychotropic, narcotic/controlled, refrigerated or device-linked.
Prescription documents
Signed prescription or letter, diagnosis where appropriate, contact details and travel dates.
How you will get more
Local doctor, named pharmacy or hospital, lead time, rules for alternatives and an emergency backup.
Check every active ingredient before travel

Plan how to obtain repeat medicines
Match each medicine to the right local provider
The aim is not simply to find a box. You need safe prescribing, a legitimate product, any required monitoring and a backup when the usual pharmacy or clinic cannot help.
| Need | Where to start | What to check before relying on it | Backup |
|---|---|---|---|
| Regular repeat prescription | Create a local prescriber and pharmacy route before the carried supply runs low. | Ingredient, formulation and locally registered product; appointment and order lead time. | A hospital pharmacy or specialist who can select a clinically appropriate alternative. |
| Controlled or psychiatric medicine | Confirm import legality, then identify a locally authorised prescriber and dispensing route. | National category, permit/quantity, prescription rules and continuity without postal imports. | Pre-travel treatment review; never stop or substitute abruptly without clinical advice. |
| Refrigerated / device-linked treatment | Map compatible product, needles/device, storage and power from airport to home. | Labelled temperature range, excursion rule, pharmacy stock and backup refrigeration. | Named clinic/hospital capable of storing and supplying it during an outage. |
| Child medicine | Use a paediatric clinician/pharmacist for weight-based dose and local concentration. | Current weight, mg dose, mg/mL concentration and suitable measuring device. | Hospital/urgent care when the child is very young, seriously unwell or dosing is unclear. |
| Antibiotic or acute treatment | Seek assessment rather than choosing a familiar box or using leftovers. | Diagnosis, allergies, interactions, dose/duration and when review is required. | Clinic/hospital escalation; avoid fragmented courses from several sellers. |
At the pharmacy counter
Five checks before taking a newly supplied medicine
Repeat the checks whenever the product, pharmacy, supplier or packaging changes.
Provider
Use a licensed pharmacy or hospital dispensary and confirm a pharmacist is available for prescription, interaction and substitution questions.
Product
Match product name, active ingredient, strength, dosage form, manufacturer, registration number, batch and expiry against the national regulator where possible.
Pack
Reject broken seals, loose unlabelled units, altered expiry/batch details, damaged cold-chain packaging or a leaflet that does not match the medicine.
Record
Keep prescription, receipt, box and pharmacist/doctor details; photograph both sides before discarding travel packaging.
Counselling
Ask what changed from the previous product, how to take/store it, interactions, missed-dose action and which symptoms need urgent care.
Similar does not always mean equivalent
How to check whether a medicine is a suitable match
Changing products can be routine and safe when a qualified professional confirms the details. The table explains why one matching feature is not enough.
| What matches | Enough? | Why it is not enough by itself | What to confirm |
|---|---|---|---|
| Same brand | No | A brand can have different ingredients, strengths or formulations between countries. | Active ingredient + exact strength + dosage form + release mechanism. |
| Same active ingredient | Not always | Modified-release, salt, concentration, device and route can change use and exposure. | Prescriber/pharmacist confirms the complete product and dose. |
| A pharmacist says it is equivalent | Useful evidence | It still needs to be tied to the prescription, patient and local substitution rules. | Record product, advice, dose and who supplied it. |
| Regulator search result | Necessary check | Registration supports legitimacy but does not prove current stock or suitability for this patient. | Active registration plus licensed seller, intact pack and clinical fit. |
| Online listing or social recommendation | No | A listing can be counterfeit, unlicensed, wrongly stored or copied from a genuine product. | Move the purchase into a licensed clinical/pharmacy route. |
Heat, freezing and power cuts
Protect medicines throughout the journey and at home
“Keep cool” is not a precise storage instruction. Follow the labelled conditions and advice from the manufacturer or pharmacist for the exact product.
- 1
Ask the manufacturer or pharmacist
Record the labelled range, allowed excursions, light/moisture limits and what counts as a spoiled dose.
- 2
Protect the journey
Keep essential medicine in hand luggage, preserve original labels and use an approved insulated system—never direct contact with loose ice.
- 3
Check storage at home
Check actual room or refrigerator temperature, backup power and whether children or household staff can access the medicine.
- 4
Plan the outage
Name a pharmacy, clinic or hospital with appropriate storage and transport; decide how long the current pack remains usable.
- 5
Do not guess after failure
If heat, freezing, water or a power cut may have compromised the product, quarantine it and ask the manufacturer/pharmacist before use.
Useful local labels
Four terms that make the handover clearer
Show the written active ingredient and prescription as well; pronunciation alone is not medicine identification.
Pharmacy / drug shop.
Pharmacist.
Active ingredient; useful in Thai FDA searches.
Controlled medicine; ask which exact legal category applies.
Availability is local
Compare pharmacies and prescribing access by family base
A national product registration does not mean the medicine will be stocked in the city, island or exact pharmacy where the family will live.
Bangkok
What you can accessDeep hospital, specialist and pharmacy choice.
What to checkExact branch stock, Thai registration, prescriber route and travel time outside office hours.
Chiang Mai
What you can accessStrong routine private/hospital access, with fewer substitutes for some specialties.
What to checkOrder cycle and Bangkok referral/supply route for the exact formulation.
Phuket and islands
What you can accessConvenient routine pharmacies but island logistics can affect specialist/cold-chain stock.
What to checkHospital pharmacy, delivery conditions and storm/ferry/road disruption buffer.
Five assumptions to avoid
Do not rely on shortcuts for essential medicines
Each shortcut replaces an important legal, clinical or supply check with an assumption.
30 days treated as a controlled-drug rule
It is the ordinary-medicine traveller limit; narcotics and psychotropics follow different schedules and permit rules.
Cannabis or hemp product in a supplement
A product legal elsewhere may be prohibited or separately controlled for import.
Brand match without formulation match
Confirm ingredient, strength, form and release mechanism with a pharmacist/doctor.
Pharmacy sale replacing a diagnosis
Seek assessment for children, serious symptoms, antibiotics, psychiatric or long-term changes.
Posting repeats
The traveller exemption applies to accompanied personal effects, not a standing mail-order pathway.
Connect the care plan
Put medicine continuity inside the wider move
Prescriptions depend on the healthcare, insurance, emergency and location decisions around them.
Common questions
Questions about medicines and pharmacies in Thailand
Can I use a foreign prescription at a pharmacy in Southeast Asia?
Do not assume it can be dispensed directly. Your existing prescription and clinician’s letter are valuable clinical and border evidence, but a local doctor or locally valid prescription may be required. Confirm the route for the exact medicine, especially controlled, injectable, psychiatric and paediatric products.
Should I search for my medicine by brand name?
Start with active ingredient, exact strength, dosage form, route and release mechanism. Brand names differ between countries and an identical-looking name may not mean an identical product. A prescriber or pharmacist should confirm any switch.
Is medicine bought from a large online marketplace safe?
A popular platform or convincing listing does not prove licensing, registration, authenticity or storage. Use a licensed pharmacy or hospital route, verify the product through the national regulator where available and retain the receipt and intact pack.
Can medicines be posted from home after we move?
Do not build continuity around post. Postal imports are regulated separately and may require licences, prescriptions or exemptions; controlled medicines may be prohibited. Confirm the current regulator and customs rules before sending anything and create a lawful local prescribing route.
How should medicines be carried on a flight?
Keep essential medicine and documents in hand luggage in original labelled packaging, within airline liquid/sharps rules. Split an appropriate backup only when lawful and clinically suitable. For temperature-sensitive products, obtain product-specific handling instructions rather than improvising with ice.
What should parents check before giving a child a local medicine?
Confirm the active ingredient, concentration, formulation, child’s current weight, dose unit, measuring device, maximum daily dose and whether another cold/fever product duplicates an ingredient. Seek clinical advice for uncertainty or serious symptoms.
How much ordinary prescription medicine can I take into Thailand?
Thai FDA guidance allows a traveller to carry a finished modern medicine for personal use for no longer than 30 days, kept in its original container with the prescription. First check that the ingredient is not a narcotic, psychotropic or otherwise prohibited/controlled product.
Do I need a Thai FDA permit for ADHD, anxiety or sleep medication?
Possibly. Thai schedules—not the category used in your home country—control the answer. Thai FDA lists substances such as methylphenidate, zolpidem, midazolam and some benzodiazepines within psychotropic rules. Use the official ingredient checker and apply at least 15 days before travel if the category or quantity requires a permit.
