Korea Medication Import Rules: Complete Guide by Pharmacist
One of the major concerns when traveling internationally is whether you can bring your regular medications with you. When traveling to or conducting business in Korea, the rules for bringing medications—from over-the-counter cold remedies to prescription drugs—are complex and often misunderstood. This article explains Korea's pharmaceutical laws, prohibited ingredients, and required documentation from a pharmacist's perspective to help you understand the import rules clearly.
Basic Rules for Importing Medications into Korea
Permitted Quantities and Duration
The first key criterion for importing medications into Korea is "quantities limited to personal use only."
| Medication Category | Permitted | Quantity Guide | Notes |
|---|---|---|---|
| Prescription medications (prescribed by doctor) | ✓ Yes | Approximately 30 days | English prescription recommended |
| Over-the-counter medications (cold remedies, etc.) | ✓ Yes | 1 month supply | Household staples approximately 1 unit per type |
| Medical prescription drugs | △ Requires confirmation | Limited quantity | Consult Korean embassy in advance |
| Quasi-drugs/supplements (vitamins, etc.) | ✓ Yes | Approximately 2 months | Ingredient composition requires attention |
Critical Point: Korean customs strictly interprets "amounts within the range of normal personal use." Bringing large quantities of multiple types of medications may be deemed for sales purposes, with risks of confiscation or entry denial.
Pharmacist's note
According to Korea's Ministry of Food and Drug Safety (MFDS), the standard for personal use quantities is based on your length of stay. For example, for a one-week stay, a 7-day supply is within reasonable limits. If bringing medications for 10 or more days, a doctor's certification letter helps facilitate smooth processing.
Prohibited and Regulated Medication Ingredients in Korea
Prescription Medications and Prohibited Ingredients
Several ingredients commonly used in Japan are prohibited or restricted in Korea. Below are ingredients that frequently cause import issues:
| Ingredient | Common Medications Containing It | Korea Status | Action |
|---|---|---|---|
| Penicillin V | Amoxicillin-containing preparations | Approved medications only | English prescription copy required |
| Sumatriptan | Imigran (migraine medication) | Medical prescription drug | Doctor's certification letter required |
| Tramadol | Tramcet (pain reliever) | Controlled substance list | Import prohibited |
| Phenobarbital | Sleep aids, anticonvulsants | Controlled substance | Import prohibited |
| Risperidone | Antipsychotic drug | Prescription limited | Doctor's certification + quantity limits |
| Flunitrazepam | Rohypnol (sleep medication) | Illegal drug classification | Absolutely prohibited |
| Ephedrine | Comprehensive cold remedies, bronchial asthma medications (some) | Restricted substance | Permitted with doctor's certification (approximately 15-day supply) |
Caution: Dangerous Ingredients in Over-the-Counter Medications
The following ingredients may be contained in over-the-counter drugs, and importing them unknowingly frequently causes problems:
- Ephedra (Mahuang): Contained in cold medicines and diet supplements → Regulated
- High-dose diphenhydramine preparations: Certain brands of sleep aids → Import restricted
- Disopyramide: Arrhythmia treatment drug → Medical prescription drug classification
Pharmacist's note
Special attention is needed for "herbal medicine components." Herbal medications such as ephedra and Boesenbergia (防風通聖散) may appear safe by appearance but are sometimes classified as illegal diet drugs in Korea. Chinese medicine-based supplements should also be verified beforehand.
Required Documentation for Importing into Korea
Preparation of English Prescriptions and Medical Certificates
When bringing prescription medications, the following documents facilitate smooth customs inspection. Consult your doctor 1-2 weeks before your trip.
| Document Type | Necessity | How to Obtain | Validity Period |
|---|---|---|---|
| English prescription | △ Recommended | Request from your doctor (approximately ¥1,000-2,000) | 3 months from issuance |
| English medical certificate | ○ Strongly recommended | Request from doctor (approximately ¥2,000-3,000) | 6 months from issuance |
| Medication handbook (English translation) | △ Supplementary | Available from pharmacy | Always keep current |
| Medication ingredient list (English) | ✓ Nearly essential | Obtain from pharmacy | Always valid |
Example of English Prescription
Obtain a document from your doctor containing the following information:
Prescription
Patient Name: ___________
Diagnosis: Hypertension
Medication: Amlodipine 5mg
Dosage: Once daily
Duration: 30 days
Indication for travel to Korea: ___________
Issued by: [Dr. Name], License No. [###]
Date: ___/___/20__
Pre-Import Checklist
Confirm the following one week before departure:
- List all medications you will bring on paper
- Know each drug's ingredient name in English (verify at pharmacy)
- Cross-reference with prohibited ingredient list (see Ministry of Foreign Affairs link below)
- Adjust quantities to 30 days or less
- Obtain English prescription for prescription medications
- Keep medications in original containers and boxes
- Do not discard original packaging (exterior boxes)
Pharmacist's note
The biggest pitfall is "removing medications from original containers." Transferring to zip-lock bags or pill cases is suspected as smuggling. Always bring medications in the condition received from the pharmacy when going through customs inspection.
Customs Declaration Procedures and Actual Process
How to Declare Medications at Incheon Airport

Frequently Asked Questions

If You Need Medications in Korea
How to Obtain Medications Locally
If your imported medications are confiscated or you run out:
| Facility | Available Medications | Language Support | Price Range |

Pharmacist's note
Under Korea's "Medical-Pharmacy Separation" system, pharmacies can dispense certain medications without prescriptions. However, consult the pharmacist regarding efficacy and usage. English-friendly large pharmacies are concentrated in Myeongdong and Gangnam districts.
