You can bring adrenaline auto-injectors such as EpiPen or Jext into Thailand without a permit: adrenaline is not a controlled drug there, so the ordinary rule applies (pharmacy-labeled packaging, paperwork from your doctor, up to 30 days' use, as of October 2026). Bring all you need from home, keep the pens out of the heat, and know that the ambulance number is 1669.
For someone with a severe allergy, Thailand is manageable with preparation. The risks are the familiar ones, food, insect stings and medicines, with a few local twists: peanuts and shellfish in many dishes, a hot climate that is hard on auto-injectors, and pharmacies where medicines can be bought without the checks you may be used to.
This page is about medical preparedness: carrying adrenaline, keeping it usable and getting help fast. It is not medical advice. Your allergy specialist or doctor should give you a written action plan before you go, and that plan comes first.

Bringing adrenaline pens into Thailand
Only medicines that Thailand's Food and Drug Administration (FDA) classes as narcotics or psychotropics need special paperwork to enter Thailand. Adrenaline appears in neither of its September 2025 tables. The general procedure for medicines is set out in our overview of prescription medicine at Thai customs; for auto-injectors, the ordinary rule is all that applies.
Under that rule, the Royal Thai Embassy in London says, a traveler may carry enough for up to 30 days, labeled as dispensed and supported by the doctor's prescription or a letter. For auto-injectors, which you carry in case you need them rather than use daily, a letter that names the device and says you must carry it at all times is the useful document.
The NHS tells people at risk of anaphylaxis to carry two adrenaline auto-injectors at all times, to check the expiry dates regularly and to replace them before they expire. Check the dates before you book the trip, not the week you leave; a pen that expires halfway through a holiday is a real gap.
Auto-injectors at airport security
An auto-injector contains liquid, so the cabin liquid rule matters. Since March 2026 the Thai aviation regulator's limit is 100 ml per container and one liter per passenger, but Suvarnabhumi Airport's official guide lists medicines among the exceptions. The condition is a label, certificate or other medical document with your name on it, a quantity that fits the journey, and that you hand the pens to the officers at screening. Our guide to airport security in Thailand explains the full liquids rule.
The Thai airport guide does not mention needles or auto-injectors by name. Keep the pens in their boxes with the pharmacy label, carry the doctor's letter in the same bag, and ask your airline in advance if you are unsure. Never put your only pens in checked luggage: you need them on the plane, and a delayed bag leaves you without them on arrival.
Keeping auto-injectors usable in the heat
The NHS warns against leaving adrenaline auto-injectors anywhere too hot or too cold, naming the fridge and outside in the sun as examples. Thailand is warm all year and very hot from about March to May; our guide to heat and sun in Thailand covers the heat index. The manufacturer's leaflet in your box gives the storage range for your product.
- Carry the pens on you, in a small bag in the shade, rather than leaving them in a hot car, a scooter seat box or a beach bag in the sun.
- Do not put them in the hotel fridge. Cold is a problem too, according to the NHS.
- Look at the window on the pen, if it has one, and follow the leaflet's advice if the liquid looks discolored.
- Teach a travel companion how and when to use your auto-injector; the NHS recommends practicing with a trainer pen.
Do not count on buying a replacement pen in Thailand. We could not confirm from the Thai FDA or any official source that EpiPen or another adrenaline auto-injector is registered and stocked in Thai pharmacies. The UK Foreign Office also warns that some medicines prescribed abroad may not be available in Thailand. Bring enough from home, including spares.
Food allergies: where the risk lies
Peanuts, shrimp, shellfish, fish sauce and egg turn up in many Thai dishes, often where you cannot see them. Our guide to ordering Thai food has the Thai words for common allergens, the dishes where they hide and advice on writing an allergy card; use it before your first meal out.
From a preparedness point of view, three habits matter more than any phrase. Keep your auto-injectors with you at every meal, including breakfast at the hotel. Eat where you can talk to the cook, especially at the start of a trip. And remember that a busy street stall shares one wok and one mortar for every order; our page on eating street food safely covers the hygiene side.
Packaged food from a supermarket or convenience store has a Thai-language label that identifies allergens, which a translation app can read. That makes packaged snacks the most predictable food on a long bus or boat journey.
Stings and medicine allergies
The NHS lists insect stings, such as wasp and bee stings, and medicines such as antibiotics and anti-inflammatory painkillers among the common causes of anaphylaxis. Both deserve thought in Thailand.
Stinging insects are part of outdoor life on jungle walks, waterfalls and temple grounds; our article on dangerous animals in Thailand covers the wider picture. If you react badly to stings, keep your pens in your day pack on every trek and boat trip.
Medicine allergies need care in pharmacies. Many common medicines can be bought over the counter in Thailand, as our guide to what Thai pharmacies sell without a prescription explains. The UK Foreign Office notes that outside the major chains, standards vary and pharmacists may not always check for interactions, while private and international hospital pharmacies are more reliable. Always say what you are allergic to, by the name of the active ingredient, and read the box before you take anything.
If a reaction happens
Follow the action plan your doctor gave you. The NHS's general steps for suspected anaphylaxis are to use the adrenaline auto-injector, call an ambulance and say you think it is anaphylaxis, and lie down, sitting up slowly only if breathing is difficult. The NHS also says not to stand or walk, even if you feel better, and that anaphylaxis needs treatment in hospital.
In Thailand the ambulance number is 1669. If you cannot get through, the UK Foreign Office suggests 191, the general police number, and asking for an ambulance. Our list of Thai emergency numbers explains what to say when you call, and a few basic Thai phrases help if the person answering speaks little English.
Name the nearest hospital before you check in. On a small island or in a national park, the nearest hospital can be a long boat or road trip away. Look it up when you book, save its address and phone number, and keep your insurer's assistance number with your pens.
The UK Foreign Office says all Thai hospitals require a guarantee of payment before treatment, so your insurance details matter in an emergency. Our guides to hospitals in Thailand and travel insurance explain deposits and guarantees. Declare your allergy when you buy the policy.
The NHS also suggests a medical alert bracelet or similar jewelry that tells other people about your allergy. In Thailand, where a bystander may not read English, adding the allergy in Thai on a card in your wallet is a sensible extra.
Frequently asked questions
Can I bring an EpiPen to Thailand?
Yes. Thailand does not control adrenaline as a narcotic or psychotropic, so you need no permit. Carry the pens in their pharmacy boxes together with your prescription or a note from your doctor, keep them in your hand luggage and show them at airport security.
Can I buy an EpiPen in Thailand?
We could not confirm that any adrenaline auto-injector is registered and sold in Thai pharmacies. Do not plan on buying one locally. Bring at least two from home, check the expiry dates before the trip and keep them with you at all times.
How do I keep an EpiPen cool in Thailand?
Keep it with you in a bag in the shade, never in direct sun or a hot car, and not in a fridge, because the NHS warns against both heat and cold. The leaflet in the box gives the storage range for your product.
What number do I call for anaphylaxis in Thailand?
Call 1669, Thailand's emergency medical number, and say you think it is anaphylaxis. If you cannot get through, call 191 and ask for an ambulance. Use your auto-injector as your action plan says, and stay lying down while you wait.
