Most medicine crosses the Korean border without a glance — the traveller with blood-pressure pills and a blister pack of antihistamines is not who the rules are watching. The rules are watching controlled substances, and they do not care whose doctor signed the prescription: for narcotic and psychotropic medication, Korea requires its own permission, obtained before you fly.
What needs what
| Your medication | What it needs |
|---|---|
| OTC and ordinary prescriptions (blood pressure, antibiotics, contraceptives, insulin…) | Nothing formal — original packaging, prescription copy wise |
| Stimulant ADHD meds (amphetamine family — Adderall, Vyvanse) | MFDS advance approval — mandatory |
| Methylphenidate ADHD meds (Ritalin, Concerta) | MFDS advance approval |
| Opioid painkillers (oxycodone, hydrocodone, morphine…) | MFDS advance approval |
| Some sleep / anxiety meds (benzodiazepines, zolpidem) | MFDS advance approval |
| Cannabis, THC, most CBD | Banned — no approval path for travellers |
Each row unpacked below, then the application itself.
Ordinary medicine: pack it and go
Note: Personal-trip quantities, original packaging, prescription or pharmacy label alongside
No declaration, no form. The prescription copy is not for customs so much as for continuity — it is what a Korean doctor or pharmacist works from if you lose a bag or run out. Common OTC painkillers — ibuprofen, acetaminophen — are unrestricted and sold at any Korean pharmacy anyway.
One quiet exception: some combination cold and codeine products sold OTC elsewhere are prescription-class in Korea. In trip quantities this goes unremarked; just do not arrive with a suitcase stock.
Controlled medication: the approval is not optional
Note: The offence is possession without Korean authorisation — a valid US, EU or Indian prescription is evidence of treatment, not permission to import
Korea's narcotics law classifies amphetamine-type stimulants among its most tightly controlled substances. This lands directly on ADHD travellers: Adderall and its relatives are unavailable in Korea and illegal to carry in without approval — airport detection means a drug investigation, not a fine. Methylphenidate, opioid painkillers and the benzodiazepine family sit in the same approval system.
The system exists and works: Korea grants self-treatment import approvals to travellers routinely. It simply does not grant them retroactively at the arrivals hall.
The MFDS application, step by step
Note: Apply via the MFDS self-treatment narcotics import application — allow up to two weeks' processing
What the application wants:
-
The form — the MFDS "application for import of narcotics for self-treatment", filed in advance of travel.
-
Your prescription — current, matching the exact medication and dosage you will carry.
-
A doctor's statement — diagnosis, medication, daily dose, treatment duration; in English is accepted.
-
Travel details — dates and quantity carried, which should match the trip plus a sensible margin, not a six-month stash.
Approved, you receive a document to carry with the medication — original packaging, prescription and approval letter together as one kit. Keep it in hand luggage; the kit is useless in a checked bag you cannot open at inspection.
Cannabis: the rule with no application form
Note: Korean drug law follows Korean nationals abroad and applies to visitors at the border — "it was legal where I bought it" has no standing
No THC products, full stop — and CBD occupies enough legal grey that carrying it is a bad trade for any traveller. Leave the gummies at home; this is the one category where Korea's enforcement reputation is fully earned.
The rest of the pharmacy picture
Korean pharmacies are excellent, dense and cheap for everything non-controlled — running out of ordinary medicine here is an errand, not an emergency. For the trip-planning layer around this: and .
