Check the active ingredient before packing a prescription medicine. The brand name and a prescription from home do not settle its legal status in Korea. If the medicine contains a controlled narcotic or psychotropic substance, obtain advance MFDS approval. Keep the actual permit with your documents; an application receipt is not permission to bring the medicine in.
Last reviewed: September 16, 2026. This is a practical travel guide, not medical or legal advice. Rules and controlled-substance schedules can change. Confirm your exact active ingredient with MFDS and Korea Customs before departure, and never stop or alter prescribed treatment without consulting your clinician.
Can you bring prescription medication to Korea?
For many travelers, the answer is yes when the medicine is for personal treatment, carried in a reasonable travel quantity, and supported by clear documentation. The important exception is medication that Korea classifies as a narcotic or psychotropic substance. Those medicines need an MFDS permit before entry.
This distinction can surprise visitors. A medicine may be routinely prescribed in your country yet controlled in Korea. Korea Customs specifically warns travelers to check the ingredient in cold medicine, sleeping pills, diet pills and other products—not simply the product name.
| Your situation | Best action before flying |
|---|---|
| Ordinary prescription medicine with no controlled ingredient | Keep it in labeled original packaging and carry a prescription or doctor’s letter. Confirm unusual products or large quantities with MFDS or Customs. |
| Medicine may contain a narcotic or psychotropic ingredient | Check the active ingredient and obtain the MFDS self-treatment permit before entry. |
| You cannot identify the ingredient | Ask your pharmacist for the generic/active ingredient in English and contact MFDS before packing it. |
| CBD, medical cannabis or a cannabis-derived product | Do not assume it is permitted because it is medical or legal at home. Korea treats cannabis-related substances strictly; obtain direct official guidance. |
| Medicine will be mailed after you arrive | Do not use shipping as a shortcut. Postal or courier imports follow separate clearance rules and can be detained. |
Check the active ingredient—not just the brand
Two packages with different brand names may contain the same controlled ingredient. Conversely, similar-looking products may have different formulas in different countries. Find the line marked “active ingredient,” “generic name,” or “INN” on the label or prescription.
Korea Customs lists examples that can trigger controlled-substance rules, including codeine, oxycodone, morphine, methylphenidate, zolpidem, alprazolam, lorazepam, clonazepam, dextromethorphan and cannabis-related substances. This is not an exhaustive list, and inclusion can depend on the ingredient, form and concentration. ADHD medication, sleep medication, strong pain medication, anxiety medication, cough products and weight-loss medication deserve an early check.
Practical rule: Never search only the brand name. Write down the active ingredient, strength, daily dose and total number of tablets or units.
When an MFDS permit is required
MFDS states that anyone entering Korea with medicine containing a controlled narcotic or psychotropic substance for personal treatment must obtain approval. The rule applies to Korean citizens and foreign visitors alike.
The official process is called the Self Treatment Narcotics Bring-in Permit. MFDS says online applications have been available since December 27, 2024. The public notice does not promise that a late application will be approved before your flight, so apply several weeks before travel whenever possible and allow time to correct missing documents.
Start with the official MFDS permit notice and the English portal at NEDrug. Use the newest forms and instructions shown there.
Submitted is not approved: An application receipt or pending status is not a bring-in permit. Before packing a controlled medicine, obtain the actual approval and check that its medicine, quantity and travel details match your trip. If the application is incomplete, ask MFDS what must be corrected rather than assuming the original submission date guarantees approval.
Quantity is not the same as permission: Korea’s INCB country sheet dated January 10, 2025 lists up to 90 days’ worth for narcotic and psychotropic medicines, with the quantity and duration stated in the prescription. Treat that as an upper reference for controlled medicine—not automatic entry permission. MFDS approval is still required, and the approved quantity must match what you carry.
Documents to prepare
The exact checklist in the current MFDS application controls. A traveler should generally be ready with:
- a clear copy of the passport identity page;
- arrival and departure details, including the full period involving Korea;
- the medicine’s brand name and active ingredient;
- strength, dosage, prescribed quantity and total quantity carried;
- a valid prescription showing the patient and medicine details;
- a doctor’s letter describing the condition and treatment need;
- any export or import certificate requested for the traveler’s country or product;
- the completed MFDS application forms.
Names, dates, quantities and dosage should agree across every document. A prescription saying “take as directed” may be less useful than one that clearly states the daily dose and total quantity. Ask the clinician to use the generic ingredient name as well as the brand name.
What to ask MFDS when the ingredient is uncertain
Have your pharmacist identify the ingredient and strength first. Then use the official contact route shown in the current MFDS instructions. Korea’s 2025 country information published by INCB lists narcotics@korea.kr as the competent-authority contact.
I plan to enter Korea on [entry date] and leave on [departure date]. My medicine is [brand], containing [active ingredient] at [strength], in [tablet/liquid/other form]. My prescribed daily dose is [dose], and I intend to carry [total quantity] for my own treatment. Is this exact product subject to advance approval, and which current application instructions should I follow?
This is a question template, not a permit application. Send any requested prescription, passport or health information only through the official private submission channel—not in our comments or a public travel forum. A forum answer about a similarly named product does not establish the status of yours.
A safe timeline before your flight
Four to six weeks before travel
If you plan to bring prescription medication to Korea, begin with the ingredient check before requesting documents.
- List every prescription and non-prescription medicine you plan to carry.
- Ask a pharmacist for each active ingredient and strength.
- Check uncertain ingredients with MFDS rather than relying on a travel forum.
- Request the prescription, medical letter and any required certificate.
Well before entry
Submit a complete permit application if a controlled medicine is involved. Do not treat submission as approval or plan around a fixed turnaround time. Check the current MFDS instructions, monitor the application and leave time to correct missing documents.
Two days before departure
- Print the approval and medical documents.
- Save offline copies on your phone.
- Compare the approved quantity with the medicine actually packed.
- Keep medicine in the pharmacy-labeled container.
- Place essential medicine and documents in carry-on baggage, subject to airline security rules.
Pack medicine and border documents together
The safest way to bring prescription medication to Korea is to make every item easy to identify. Keep tablets, inhalers, injections and liquid medicines in their original labeled packaging whenever possible. Do not combine several medicines in an unmarked bag or daily organizer for border crossing. A pill organizer can be useful after arrival, but the original container helps officials identify what you brought.
Carry only the documented personal-treatment quantity. Keep the MFDS permit beside the relevant controlled medicine. If you have an item that must be declared, use the declaration channel and present the documents calmly. The Korea Customs passenger guide lists narcotics, psychotropic drugs and medicines that may be abused among declarable or restricted goods.
Liquids, syringes, cooling packs and medical devices can also be subject to airline and airport-security rules. Confirm those separately with your airline and departure airport. Border permission and cabin-baggage permission are different questions.
What not to do
- Do not hide medicine or remove identifying labels to avoid questions.
- Do not assume “over the counter” means unrestricted. Some cough or sleep products can contain ingredients controlled in Korea.
- Do not rely on a photo of someone else’s permit. Approval is tied to the traveler, medicine, quantity and travel details.
- Do not mail controlled medicine to your hotel. Shipping is not a workaround and follows separate import procedures.
- Do not replace an approved medicine or increase the quantity without checking whether the permit must be amended.
- Do not stop medically necessary treatment on your own. Ask the prescribing clinician about a lawful alternative if approval is impossible.
If your flight is soon and you have no permit
Contact MFDS immediately with the exact ingredient, quantity and entry date. A pending or last-minute application does not authorize entry, and approval before your flight cannot be assumed. Ask your clinician whether a non-controlled alternative is medically appropriate, or whether treatment can safely be arranged in Korea. Do not make that substitution yourself.
If you arrive with an undeclared restricted medicine, the consequences can be much more serious than losing the product. Korea Customs warns that controlled-drug violations can carry criminal penalties. Honest advance checking is the cheaper and safer route.
Getting medicine after arrival
Foreign prescriptions are useful medical evidence but do not automatically function as Korean prescriptions. A Korean doctor may need to assess you and issue a local prescription before a pharmacy can dispense a prescription-only medicine. Availability, brand, dosage form and insurance coverage may differ.

Frequently asked questions
Is a doctor’s letter enough?
A doctor’s letter supports a controlled-medicine application but does not replace advance MFDS approval. A prescription and labeled container alone are not sufficient when a permit is required.
Can I carry ADHD medication into Korea?
Some ADHD medicines contain ingredients controlled in Korea, including methylphenidate and certain amphetamine-related substances. Check the exact active ingredient with MFDS and obtain approval when required.
Can I bring sleeping or anxiety medication?
Some products contain controlled ingredients such as zolpidem or benzodiazepines. Brand names vary, so verify the generic ingredient and do not travel with them solely on the strength of a foreign prescription.
What about CBD or medical cannabis?
Korea applies strict controls to cannabis-related substances, and Korea Customs lists cannabidiol and tetrahydrocannabinol among controlled cannabis ingredients. Do not bring a CBD oil, gummy, cream or medical-cannabis product without direct written guidance and any required approval.
Should I declare my medicine?
Restricted goods and medicines that may be misused or abused are declarable under Korea Customs guidance. If an item is covered by a permit or you are uncertain, declare it and present the documentation rather than guessing at the border.
