Pharmacies in Thailand: no secrets. Which medicines are worth bringing from Poland, and what can you buy more cheaply locally?
March 1, 2026
Are you planning a trip to Thailand? Paradise beaches, the smells of street food… How exciting! But there is one issue that causes concern: medicines in Thailand. What can I bring with me? Do I need a certificate? What if my medicine is banned? I’ve been through this myself, scouring dozens of forums and asking myself what medicines to take to Thailand. I want to spare you this stress. In this guide, based on my own experience, I will explain how to safely and legally prepare your medicines for a trip to Thailand. Peace of mind when travelling is priceless – let’s take care of it together.
Importing medicines into Thailand – what are the key rules of the Thai FDA?
Before you pack your first aid kit, familiarise yourself with the rules of the Thai Food and Drug Administration (FDA). It is the FDA that decides whether the transport of medicines to Thailand will go smoothly, and understanding its guidelines is essential for a peaceful journey.
What are the current Thai FDA guidelines for tourists importing medicines?
The key rule is simple: you can bring in medicines for your own use for a maximum of 30 days. This applies to most standard medicines that do not contain psychotropic substances or narcotics (drugs). Remember that “personal use” is the key phrase. Carrying medicines for someone else is considered smuggling.
This 30-day rule is a starting point. As usual, the devil is in the details, especially when it comes to specialised medicines.
Where can I find the official list of medicines prohibited for import into Thailand?
The official list of controlled substances, which is essentially a list of medicines prohibited in Thailand, can be found on the Thai FDA website, in the Narcotics Control Division section. The website, which is part of the Thai Ministry of Public Health, can be a little confusing, so here’s a tip: look for PDF documents named “List of Controlled Substances” or “Narcotics Act”. There you will find a breakdown into categories (e.g. Category 2 Narcotics, Category 2, 3, 4 Psychotropic Substances), which determine the rules for importing a given drug. Always check the regulations just before you leave, as they may change. Do not rely on information from forums from years ago – only the current regulations matter here.
Do ordinary headache and cold medicines need to be declared when entering Thailand?
No, common over-the-counter medicines such as paracetamol, ibuprofen or aspirin do not need to be declared as long as you have a reasonable amount for your own use. The same applies to plasters, basic anti-diarrhoea medicines for Thailand or motion sickness. However, there is one very important exception: cold and runny nose medicines containing pseudoephedrine. In Thailand, this is a controlled substance and its import is illegal. Always check the ingredients!
Prescription and medical certificate for Thailand – what documentation do you need to prepare?

Paperwork – no one likes it, but when it comes to medicines, it is your protective shield. The right documents prove to Thai customs officers that you care about your health and are not smuggling goods. Think of it as an investment in your peace of mind.
Do I need to have a prescription for the medicines I am taking to Thailand?
Yes, when it comes to prescription medicines to Thailand, you should have a copy of the document for each of them. However, a Polish prescription alone is not enough. It is only a supplement to a more important document – a certificate from a doctor in English.
What should a doctor’s certificate for importing medicines to Thailand look like?
The medical certificate is your most important document. It must be in English, preferably on the clinic’s letterhead, and contain all the key information. The official at the airport must be able to understand at a glance who you are, what you are suffering from and why you need these medicines.
Elements that must be included in the certificate:
- Your full details (first name, surname, address, passport number).
- Doctor’s and clinic details (name, address, licence number).
- Medical diagnosis (name of the disease/condition in English).
- A list of all medicines being imported, including their international names (active ingredient) and trade names.
- The exact dosage of each medication.
- Specify the total amount of medication needed for the duration of the trip (e.g. “supply for 30 days”).
- Date of issue, legible signature of the doctor and stamp (doctor’s and/or clinic’s).
Does the medical documentation for imported medicines have to be translated into English?
Absolutely yes. The customs officer in Bangkok does not speak Polish, so all documentation – the certificate and any additional opinions – must be in English. Translation of the documentation is therefore absolutely essential. Ask your doctor for this; many have ready-made templates. If they refuse, you will need to use the services of a certified translator. Do not take the risk of hoping that “somehow it will work out” – this is a sure way to have your medicines confiscated and get into serious trouble.
Does a medical certificate for Thailand need to have a wet stamp from the clinic and the doctor’s signature?
Yes, authenticity is crucial. The certificate must be an original, with the doctor’s handwritten signature and official stamp. A simple computer printout without these elements is worthless. It is the stamp and signature that confirm to the official that the document is not a forgery. Make a copy and take a photo with your phone just in case, but always keep the original in your hand luggage.
How to transport medicines to Thailand? Original packaging, hand luggage and quantity limits

Having the documents is half the battle. The other half is packing your medicines correctly. Thai regulations are precise and aim to identify substances quickly. I will show you how to do this to avoid a nervous search of your suitcase at the airport.
What is the maximum amount of medication you can bring into Thailand for personal use (30-day supply)?
The limit is a supply for a maximum of 30 days of stay, specified in dosage, not number of packages. If your stay is longer and you need more medication, the situation requires special permission from the Thai FDA. In practice, for a standard holiday, take as many tablets as your dosage requires, plus a small supply in case of delays. Do not take your entire annual supply of medication with you – this will arouse the suspicion of Thai Customs.
Do medicines brought into Thailand have to be in their original packaging?
Yes, and this is one of the most important rules. All medicines must be in their original pharmacy packaging, with the name and expiry date clearly visible. Forget about transferring tablets to travel organisers. Customs officers must be able to quickly identify the medicine and compare it with the certificate. The box with the leaflet is your proof. If the packaging is large, ask the pharmacy for a smaller one or take one, but always the original.
Can liquid medicines over 100 ml be carried to Thailand in hand luggage?
Yes, liquid medicines, aerosols and gels that are medically necessary are exempt from the 100 ml limit in hand luggage. However, you must have a certificate from your doctor in English confirming the need to carry the medicine with you. During the security check, remove these medicines from your luggage and report them for separate inspection. The liquid may be checked additionally. This will allow you to easily carry, for example, a larger bottle of syrup, and the whole process of transporting medicines in your hand luggage to Thailand will become much simpler.
Psychotropic drugs and strong painkillers – what do you need to pay special attention to?

This is the highest risk section. If you plan to take psychotropic drugs on your trip to Thailand, your preparations must be perfect. Thailand has some of the strictest anti-drug laws in the world, and many psychotropic and opioid substances are classified as drugs. There is no room for error here.
Can psychotropic drugs be brought into Thailand and what documents are required?
Yes, but the procedure is complicated and for many substances requires an import permit to be obtained before departure. These drugs are classified as Category 2 narcotics or Category 2, 3 or 4 psychotropic substances. A simple medical certificate is not sufficient. For Category 2 Narcotics, you must obtain a “Permit for Importation/Exportation of Narcotics” (IC-2 form) by submitting an application at least two weeks in advance.
How do I obtain an IC-2 permit to import medicines into Thailand?
Start the process at least one month before departure. Here are the steps:
- Go to the Thai FDA (Narcotics Control Division) website.
- Check if your medicine is on the Category 2 Narcotics list.
- Download the current IC-2 form.
- Fill it out carefully.
- Gather all the necessary documents: the form, a copy of your passport, a doctor’s certificate in English, and a copy of your prescription.
- Send everything by email to the address provided on the FDA website.
- Wait for official permission. Once you receive it, print it out and take it with you.
Without this document, importing drugs from this group is illegal and may result in arrest and deportation.
What are the restrictions on transporting Diazepam and other benzodiazepines to Thailand?
Diazepam (Relanium), alprazolam (Xanax) and other benzodiazepines are classified as Category 2 or 4 psychotropic substances. Their import is controlled. They do not require an import permit (IC-2 form), but you must carry a certificate from your doctor in English confirming the need for their use. The supply must not exceed 30 days.
Can a tourist enter Thailand with Tramadol or codeine-containing medicines?
This is a tricky subject. Tramadol is a strictly controlled drug. Codeine is classified as a category 2 narcotic, so its import requires prior authorisation (form IC-2). Attempting to bring it in without this document, even with a prescription, can have serious consequences. I strongly advise against taking any codeine-based medicines to Thailand without completing the official procedure. The safest option is to talk to your doctor and find a legal alternative painkiller for your trip.
Are cold medicines containing pseudoephedrine legal for tourists in Thailand?
Absolutely not. Pseudoephedrine is a controlled substance in Thailand because it is used to produce methamphetamine. This is one of the most common mistakes made by tourists. Many cold medicines popular in Poland (e.g. some versions of Cirrus, Acatar, Sudafed) contain it. Always check the ingredients of your “flu” medicines. Possession of pseudoephedrine is treated very seriously. You can buy effective and legal cold medicines for pennies at any local pharmacy.
Is it legally safe to bring strong sleeping pills into Thailand?
It depends on the active ingredient. Medicines such as zolpidem (e.g. Stilnox) and zopiclone are classified as psychotropic substances and are subject to the same restrictions as benzodiazepines – they require a medical certificate in English. Check which category Thai law classifies the active ingredient in your medicine as. If in doubt, send an email to the Thai FDA – it is better to ask than to take a risk.
Chronic illnesses and common medications – how to prepare for a trip to Thailand?
Travelling with a chronic illness requires additional planning, but it should not stop you from exploring the world. The key is to prepare carefully and understand the rules regarding your medications.
How to prepare for travel when taking regular medication for chronic conditions?
Make an appointment with your doctor at least 4-6 weeks before departure. Ask them for a certificate in English, in accordance with the guidelines described above. Check the active ingredients of your medications on the Thai FDA lists to make sure they do not require additional permission. Always carry your medication in your hand luggage, in its original packaging. Take enough for the entire trip plus a few extra days. Never assume that you will be able to buy your medication locally.
What are the restrictions on importing ADHD medications (e.g. Concerta, Medikinet)?
ADHD medications containing methylphenidate are classified as Category 2 drugs in Thailand. This means that they can only be imported legally after obtaining an IC-2 permit from the Thai FDA. The procedure is the same as for codeine. You must submit your application with all the necessary documents well in advance. Attempting to import these medications without a permit is treated as drug smuggling.
What are the rules for diabetics travelling to Thailand with insulin and needles?
People with diabetes can easily carry insulin, pens, needles and a blood glucose meter. Insulin is not a controlled substance, but as it is a prescription drug, a certificate from your doctor in English is required. This will explain to customs officials why you are carrying the liquid, needles and specialised equipment. Pack all these items in your hand luggage, preferably in a thermal bag, and inform the staff during security checks.
Do I need special permits to bring asthma inhalers into Thailand?
Standard asthma inhalers, e.g. with salbutamol, generally do not require special permits as they are not on the list of controlled substances. Nevertheless, I always recommend taking a certificate from your doctor in English. This is good practice, as it will immediately clarify the situation if any questions arise. Carry your inhaler in your hand luggage and in its original packaging.
Can antibiotics be freely carried in hand luggage to Thailand?
Yes, if you have a prescription and a medical certificate. Antibiotics are not on the list of controlled drugs, but as prescription drugs they require documentation. Carry them in your hand luggage, in their original packaging and in the amount prescribed by your doctor. It is worth knowing that in Thailand you can buy many antibiotics in a pharmacy without a prescription after consulting a pharmacist, but it is safer to have a medicine that you are familiar with.
Are contraceptive pills considered reportable drugs in Thailand?
No, contraceptive pills are not controlled medicines and do not require special permits or declarations. For the sake of order, it is worth carrying them in their original packaging in your hand luggage, but you do not need to obtain a special certificate for them.
What are the current regulations on importing medical marijuana products into Thailand?
There is an absolute ban. Despite a period of liberalisation of the regulations, since June 2025, cannabis has once again been classified as a controlled substance. The import of any products containing cannabis, including THC and CBD (even oils), is strictly prohibited for tourists. It does not matter if you have a prescription for them in your country. Attempting to import medical cannabis will be treated as drug smuggling, which is punishable by arrest and deportation, a fine, and in the worst case, many years in prison.
Travel first aid kit and procedures at Bangkok airport – what you need to know
Now that you know what is and is not allowed, it’s time to put it into practice. The question “what to pack in a first aid kit for Thailand?” keeps many travellers awake at night. And how should you behave at Bangkok or Krabi airport to ensure a smooth check-in? Here are some proven tips.
What should a safe and legal first aid kit for Thailand contain?

Minimalism is key, because Thai pharmacies are well-stocked. It is worth taking a small emergency kit with you, which will allow you to react immediately, without having to search for a pharmacy at midnight.
| What to take from Poland? | What can you buy cheaper/easier in Thailand? |
|---|---|
| Prescription drugs for chronic diseases (a whole supply!) | Paracetamol, Ibuprofen (they have them everywhere, even at 7-Eleven) |
| A proven anti-diarrhoea medicine (e.g. Loperamide) for the “first shot” | Mosquito repellents with DEET (local ones are more effective against local insects) |
| Plasters, small disinfectant liquid and antibiotic ointment | The famous Tiger Balm for muscle pain and insect bites |
| Probiotics to prepare the bacterial flora | Herbal nasal inhalers (Ya Dom) – great for runny nose and congestion |
| Allergy medication, if you have tried and tested strong ones | Creams with high UV filters (they are cheaper and available in a huge selection) |
Are my medicines available without a prescription at Boots or Watsons pharmacies in Thailand?

You may be pleasantly surprised. Pharmacy chains such as Boots and Watsons are well-stocked, and the pharmacists speak English. Many medicines that require a prescription in Poland (e.g. some antibiotics, herpes medicines such as acyclovir) can be purchased in Thailand without any problems after a short consultation. Prices are often much lower. So there is no point in bringing cough syrup from Poland “just in case” – you can buy it locally for a few zlotys.
When do I need to go to the “Red Channel” at the airport with my medicines?

You must go to the “Red Channel” (Goods to Declare) if you are bringing in Category 2 narcotics for which you have obtained an IC-2 permit. There, you present the medicine, permit and passport to the official. This is a crucial moment, as it is the official declaration of medicines at the Thai border. If you have any doubts about the legality of your medicines or their quantity, also choose the red channel. The rule is simple: it is better to declare and explain than to get caught in the “Green Channel”. Honesty is the best strategy.
How to contact the Thai Ministry of Public Health about rare medicines?
If you are taking a rare medicine and cannot find any information about it, contact the Thai FDA (Food and Drug Administration) directly, specifically the Narcotics Control Division. The Thai Ministry of Public Health website should provide an email address for international enquiries (e.g. tnarcotics@fda.moph.go.th). Write a short message in English, giving the international name of the active substance and ask about the import procedure. The answer will give you 100% certainty.
What are the penalties for illegally importing medicines into Thailand?

This topic cannot be ignored. You must be aware that Thai anti-drug laws are ruthless, and ignorance of them is no excuse. Treat this as the most important warning.
What are the consequences for a tourist for possessing illegal drugs without a permit?
The consequences depend on the category of the substance. In the best case scenario, with a lower control category, you will end up with the confiscation of the drug and a heavy fine. In the worst case scenario, if it is a category 1 or 2 substance (e.g. ADHD drugs without a permit, codeine), you face arrest, trial, possible deportation and imprisonment. Thai prisons are not places where you want to spend your holidays.
What are the penalties for importing prohibited narcotic substances?
There are no lenient penalties here. Importing category 1 drugs (e.g. heroin, methamphetamine) or possessing precursors such as pseudoephedrine is treated as smuggling. The penalties are draconian: from long-term imprisonment to life imprisonment and even the death penalty (although rarely enforced for foreigners, it is still included in the penal code).
Can I carry medication in my luggage for a friend living in Thailand?
Absolutely not. By doing someone such a “favour”, you take 100% criminal responsibility upon yourself. You cannot be sure what is in the package and whether your friend has a permit for these medicines. For Thai customs, you are the importer. If the medicines turn out to be controlled, you will face the consequences. Never carry medicines or any packages for third parties. This is a fundamental rule of safe travel.
