Complete Guide to Taiwan Medication Import Rules: Prescription Drugs, OTC Medicines, and Required Procedures
Taiwan has high medical standards, and common pharmaceuticals are readily available locally. However, when importing medications from Japan, you must comply with Taiwan's strict pharmaceutical regulations. This article, compiled from a pharmacist's perspective, covers Taiwan's medication import rules, prohibited substances, and necessary documentation.
Pharmacist's note Medication imports to Taiwan are limited to quantities for "personal use" only. As of 2026, Taiwan's pharmaceutical management strictly distinguishes between prescription drugs and non-prescription medicines. We recommend regularly checking the official website of Taiwan's "Taiwan FDA (Food and Drug Administration)" (TFDA) for the most current detailed information.
Basic Rules for Importing Medications to Taiwan
Definition of "Personal Use" and Quantity Limits
Taiwan's customs and health authorities determine "personal use" based on the following criteria:
| Type of Medication | Permitted Quantity | Notes |
|---|---|---|
| Prescription drugs (external) | One course of treatment (typically ~30 days) | Doctor's prescription required |
| Prescription drugs (oral) | One course of treatment (typically ~30 days) | Doctor's prescription required |
| OTC medications | Reasonable quantity | Aim for 12 units or fewer |
| Vitamins and supplements | Reasonable quantity | May be treated as dietary supplements |
| Medical devices (blood glucose monitors, etc.) | One personal set | Spare batteries separate |
Key point: Quantities exceeding "personal use" may be classified as for resale purposes and subject to confiscation and fines.
Permissible Medications and Documentation Requirements
Essential Documentation for Importing Prescription Drugs
When importing prescription drugs (especially psychiatric medications, cardiac medications, and hormone preparations), the following documents may be required:
Required Documents Checklist:
- ✓ Doctor's prescription (original or copy)
- ✓ Doctor's English-language medical certificate or explanation letter (English or simple Chinese preferred)
- ✓ Photocopy of passport
- ✓ Japanese medication name and ingredient list on packaging (photograph acceptable)
Pharmacist's note Prescriptions often don't need to be originals—copies usually suffice. However, for psychiatric medications and narcotic painkillers, an English-language explanation letter from your doctor streamlines customs inspection. Having "For personal use only" clearly stated is effective.
Generally Permissible OTC and General Medications
The following OTC and general-use medications can be imported relatively easily:
| Medication Category | Examples | Active Ingredients | Precautions |
|---|---|---|---|
| Cold medicines | Lulu, Pabron | Acetaminophen, dextromethorphan | ~30 days' supply generally acceptable |
| Digestive aids | Seirogan, Biofermin S | Wood creosote, Bifidobacterium | Seirogan has been confiscated as folk remedy |
| Headache medicines | Loxonin S | Loxoprofen sodium | ~15 days' supply recommended |
| Allergy medicines | Allegra FX, Alerzine | Fexofenadine, epinastine | Second-generation antihistamines are safe |
| Skin ointments | Zarne, Muhi | Heparinoid, cream base | External medications generally tolerated |
| Laxatives | Colax | Bisacodyl | 1-2 weeks' supply |
| Pain relief patches | Loxonin Tape | Loxoprofen NS | 10-20 patches acceptable |
| Eye drops | Rohto Medicquark, Sante Medical | Ketotifen, tetrahydrozoline | Routine amounts only |
| Lozenges and gargles | Lozenges, propolis | Lysozyme, iodine solution | Generally no issues |
| Vitamins and supplements | Chocola BB, Yunkel | B vitamins, herbal ingredients | Treated as supplements (see details below) |
Prohibited and Restricted Medications in Taiwan
Absolutely Prohibited Medications
The following medications are likely to result in confiscation and fines, so avoid importing them:
| Prohibited Substance/Medication | Reason | Alternative |
|---|---|---|
| Narcotic painkillers (morphine, oxycodone, codeine-containing drugs) | Class I controlled substance under Taiwan narcotics law | Fentanyl patches also require prior approval |
| Certain psychotropic drugs (alprazolam, midazolam, etc.) | Regulated as abuse substances | Obtain local doctor's prescription |
| Diphenoxylate-containing antidiarrheals (Loperamium, etc.) | Abuse risk | Purchase Taiwan OTC antidiarrheal |
| Asbestos-containing medications (asbestos-containing plasters) | Carcinogenic substance | Do not use |
| Unapproved or unlicensed medications | Difficult to distinguish from counterfeit | Purchase only through authorized channels |
Pharmacist's note Codeine-containing combination cold medicines (e.g., Ascolin combination oral liquid) and chlorpromazine-containing medications are also regulated in Taiwan. Many seemingly "cold medicines" actually contain narcotic or psychotropic components, so checking ingredient lists is essential.
Medications Requiring Prior Approval for Import
The following medications may be permitted with prior application to Taiwan's Ministry of Health and Welfare:
Examples of medications requiring prior approval:
- Antiepileptic drugs (phenytoin, valproic acid) → Limited to patients with active seizure control
- Immunosuppressants (tacrolimus, cyclosporine) → Clear medical necessity (transplant patients, etc.)
- Insulin preparations and self-injection drugs → Required for diabetes management; doctor's explanation letter essential
- Anticoagulants like warfarin → Doctor's prescription + English explanation letter
- Hormone replacement therapy (HRT) drugs → Female hormone preparations, menopause treatment drugs
Prior approval application process:
- Obtain English-language medical certificate from your Japanese doctor
- Consult in advance with Taiwan's Representative Office in Japan (embassy equivalent)
- Apply directly to Taiwan's TFDA (online application available)
Medication-Specific Precautions
Psychiatric and Neurological Medications
The following medications prescribed in Japan are heavily regulated in Taiwan:
| Medication | Generic Name | Taiwan Classification | Strategy |
|---|---|---|---|
| Depas | Etizolam | Class III controlled substance | Detailed doctor's explanation letter required |
| Xanax | Alprazolam | Class II controlled substance | Difficult to import (local prescription recommended) |
| Halcion | Triazolam | Class II controlled substance | Difficult to import |
| Lunesta | Eszopiclone | Class III controlled substance | Possible with doctor's explanation letter |
Pharmacist's note Sleeping pills and anti-anxiety medications are often treated as medical narcotics in Taiwan, making imports extremely high-risk. For short stays (3 days or less), bringing a prescribed quantity may be possible, but we recommend having your Japanese doctor prepare an English explanation letter and consulting with Taiwan medical facilities or hospitals with Japanese-language support before your trip.
Antibiotics
Bringing antibiotics for preventive use with self-judgment is not recommended.
- Amoxicillin and other common penicillin-based antibiotics → 1-2 weeks' supply acceptable for mild cases
- Fluoroquinolones (Cravit, etc.) → Doctor's prescription and medical certificate advisable
- Oral antifungals (itraconazole, etc.) → Prescription and doctor's explanation letter required
Recommended approach: It's safer to see a local doctor and obtain antibiotics in Taiwan after symptoms develop. Taiwan's medical facilities meet or exceed Japanese standards.
Hormone Medications and Reproductive Health Drugs
Regulations on women's medications are also strict, requiring attention:
| Medication | Active Ingredient | Taiwan Classification | Required Documentation |
|---|---|---|---|
| Oral contraceptives (birth control pills) | Norethindrone, etc. | Doctor prescription required; 1-month supply usually permitted | Prescription copy recommended |
| HRT drugs (menopause treatment) | Estradiol, progesterone | Medical necessity documentation required | Doctor's English medical certificate |
| Ovulation induction drugs | Clomid, etc. | Medical necessity documentation required | Doctor's English certificate + prescription |
Packing and Customs Declaration
Efficient Packing Method
When packing medications to import to Taiwan, follow these guidelines:
Checklist:
- ✓ Keep medications in original packaging (avoid opening or transferring)
- ✓ Group medications together in an easily visible location for customs
- ✓ Store prescriptions and doctor's explanation letters separately (for easy presentation)
- ✓ Keep passport photocopy with medications
- ✓ Liquid medications in carry-on baggage if ≤100ml; fewer restrictions
- ✓ Tablets and powders generally acceptable if ≤100g
How to Fill Out Customs Declaration Form
Taiwan's "Passenger Customs Declaration Form" at entry has a section for medications:
Sample entry:
□ I am carrying pharmaceuticals
Number of types: ○
Main medications: Paracetamol tablets (30 tablets),
Loxoprofen patches (20 patches)
Purpose of use: For personal use during 10-day stay
Doctor's explanation letter: Yes / No
Notes on completion:
- Honest declaration is most important (false declaration is a crime)
- Write in English or simple Traditional Chinese (not Simplified)
- When uncertain, declare that you're carrying items (better than later investigation)
