Travelling to Taiwan with medication is generally straightforward-but there are strict rules around quantities, prescriptions and controlled drugs. Whether you’re carrying everyday over-the-counter remedies or specialist prescriptions like ADHD medication or strong painkillers, it’s important to understand what’s allowed before you travel.
This guide breaks down Taiwan’s rules based on guidance from the Taiwan Food and Drug Administration and other official sources.
Over-the-counter (OTC) medications
Most common over-the-counter medications can be brought into Taiwan for personal use without prior approval.
This includes things like:
- Paracetamol and ibuprofen
- Antihistamines
- Cold and flu medicines
- Basic digestive remedies
Limits
Taiwan applies clear quantity limits for OTC medications:
- Up to 12 bottles/boxes total
- No more than 36 units per item (e.g. 36 tablets per type)
If you stay within these limits and the medication is clearly for personal use, you should not have any issues at customs.
Practical tips
- Keep everything in original packaging
- Avoid bringing large quantities that could look commercial
- If possible, carry a receipt or pharmacy label
Prescription medications: general rules
Prescription medication is allowed into Taiwan, but you must be able to show it is for your personal medical use.
Limits
- Up to a 2-month supply of each prescribed medication
Anything beyond this may require special approval before travel.
What you should carry
Even though it’s not always checked, you should have:
- A doctor’s letter
- A copy of your prescription
- Medication in original labelled packaging
Your doctor’s letter should include:
- Your full name (matching your passport)
- Medication name (generic + brand if possible)
- Dosage and frequency
- Total quantity
- Doctor’s name and contact details
My guide to what to include on a doctors letter for travelling medication breaks down what you should include and has real-life examples. If you’re travelling with children, make sure their names are clearly listed too.
Controlled medications (strictly regulated)
This is where travellers most often run into problems.
Taiwan strictly controls certain medications, including:
- ADHD stimulants (e.g. methylphenidate)
- Strong painkillers (opioids)
- Sedatives and sleeping tablets
- Anti-anxiety medications (certain benzodiazepines)
These fall under Taiwan’s controlled drug regulations and are monitored by the Taiwan Food and Drug Administration. To find a list of controlled medications head to this page about the Controlled Drugs Act and click on the link in the blue box which says “Schedules and Items of Controlled Drugs” which will download a word or PDF file with a list of controlled medications and which schedule they fall under in Taiwan.
Limits without prior approval
You can usually bring:
- Up to a 2-month supply for personal use
When you need approval
If:
- Your medication is classified as a controlled substance, and
- You are carrying more than a standard personal-use quantity,
you may need to apply in advance for permission. There is more information from the Taiwan Food and Drug Administration about applying for a permit for medication to come into Taiwan. This has to be sent to Taiwan by post, and once they have everything they will issue the permit within 7 working days and send it to you.
In some cases, travellers are required to submit:
- A doctor’s letter
- Prescription details
- Travel dates
- Medication quantities
Approval is typically handled through Taiwan’s health authorities before arrival.
The Taiwan FDA issued a news update in December of 2025 which includes information about travelling to Taiwan with controlled medication. Here, the TFDA states that those coming to Taiwan with schedule I to III controlled drugs can submit relevant paperwork in advance of travel for future reference.
Special note on ADHD medication
ADHD medications (such as stimulants) are one of the most commonly flagged categories.
Even if you’re within the 2-month supply:
- Carry full documentation
- Be prepared to explain your medication at customs if asked
If you’re unsure whether your medication is controlled in Taiwan, check with the Taiwan Food and Drug Administration before you travel.
Arriving in Taiwan: customs and declarations
When you arrive in Taiwan:
- Medication for personal use usually does not need to be declared if within limits
- However, controlled drugs or large quantities should be declared
Customs officers may:
- Inspect medication
- Ask for documentation
- Question quantities
If everything is clearly labelled and documented, this is usually a quick process.
What happens if you bring too much?
If you exceed the allowed limits or don’t have proper documentation:
- Medication may be confiscated
- You could face delays at customs
- In serious cases, there may be legal consequences
Taiwan has strict drug laws, so it’s not worth taking risks.

Bringing controlled medication to Taiwan FAQ
Can I bring prescription medication into Taiwan?
Yes, you can bring prescription medication into Taiwan for personal use. In most cases, travellers can carry up to a two-month supply without needing special approval. Your medication should be kept in its original labelled packaging, and it is strongly recommended to carry a doctor’s letter and a copy of your prescription. This helps avoid delays if customs officers ask questions when you arrive.
Can I bring ADHD medication to Taiwan?
Yes, but ADHD medication needs extra care because many stimulant medications are classed as controlled drugs in Taiwan. Medicines such as methylphenidate and some amphetamine-based prescriptions may be more closely checked by customs. You should carry the medication in its original packaging along with a doctor’s letter that clearly explains your diagnosis, dosage, and why the medication is required. If you are carrying a larger quantity or are unsure whether your medication is restricted, it is best to check with the Taiwan Food and Drug Administration before travelling.
Do I need to declare my prescription medication at customs?
Most standard prescription medication for personal use does not need to be declared if it is within the allowed limits. However, controlled medications, strong painkillers, sedatives, or larger quantities should be declared to avoid problems. If customs officers inspect your luggage, having your prescription and doctor’s letter ready makes the process much easier.
What drugs are restricted in Taiwan?
Taiwan has strict controls on medications that contain narcotics, stimulants, sedatives, and certain psychiatric medicines. This can include ADHD medication, opioid pain relief, strong sleeping tablets, anti-anxiety medication, and some medicines used for chronic pain or neurological conditions. Some medications that are common in the UK may be treated much more strictly in Taiwan, so it is important to check before you travel.
Does Taiwan have strict drug laws?
Yes, Taiwan has very strict drug laws, especially around controlled substances and narcotic medications. Bringing restricted medication without proper documentation can lead to confiscation, delays, fines, or serious legal consequences. Even prescription medication that is legal in your home country may require extra checks in Taiwan, so preparation is important.
What medications can you take through customs?
You can usually take over-the-counter medicines like paracetamol, antihistamines, allergy tablets, and basic cold remedies, as well as prescription medication for personal use. The key is that the medication should be for personal use only, carried in reasonable quantities, and ideally kept in original packaging. Controlled drugs need more care and should always be supported by a prescription and doctor’s letter.
If you’re travelling around Asia, it’s worth checking country-specific rules – some destinations (like Hong Kong or Japan) have stricter requirements or require pre-approval for certain medications. Head to my Asia guide to start planning your trip with autistic children.
