Traveling to Korea with prescription medication is straightforward — but only if you prepare the right paperwork in advance. Korean customs and the Ministry of Food and Drug Safety (MFDS) have clear rules about what you can bring, how much, and what documentation you need. Skip this step and you risk having medication confiscated at Incheon International Airport.
What Korea Allows: Quantities and General Rules
For personal use, Korea generally allows travelers to bring up to a 30-day supply of most prescription medications without prior approval. If you need more than 30 days’ worth — for a longer stay or as a safety buffer — you must obtain an import permit from the MFDS before you arrive.
Controlled substances require extra scrutiny regardless of quantity. This includes opioids, benzodiazepines (such as Valium or Xanax), ADHD medications like Adderall or Ritalin, and sleep aids in the Z-drug family (zolpidem, zopiclone). Korea classifies these under its Narcotics Control Act, and carrying them without proper documentation — even for clearly legitimate medical use — can result in detention and questioning by the Korea Customs Service at arrivals halls in Incheon (Terminal 1 or 2) or Gimpo Airport.
Over-the-counter medications from your home country may also be classified as prescription-only in Korea, so check before you pack.
Documents You Must Carry
Having the right paperwork makes the customs process smooth. At minimum, carry all of the following:
- Original prescription — printed on your doctor’s letterhead, with your full name, the drug name (generic and brand), dosage, and reason for use.
- Pharmacy dispensing label — the label attached to the bottle or blister pack, showing pharmacy name, patient name, and prescriber.
- Doctor’s letter in English — a brief letter explaining your diagnosis and why you must carry this medication. Korean customs officers do read English-language documents.
- MFDS import permit — required only if you exceed the 30-day limit or carry a controlled substance. Apply online at the MFDS official portal (www.mfds.go.kr) at least 2–3 weeks before departure. The permit is issued free of charge.
Keep medications in their original packaging. Do not transfer pills into a weekly pill organizer without also keeping the original labeled bottle. Loose, unlabeled pills raise flags regardless of the documentation you carry.
Arriving at Incheon: What to Expect
Most travelers carrying a routine supply of medication (blood pressure pills, thyroid medication, antidepressants, insulin) pass through Incheon customs without being stopped. Declare your medications honestly on your customs declaration form — there is a checkbox for “medicines and health supplements.” Failing to declare and then being found with controlled substances is treated as smuggling, which carries penalties up to 5 years imprisonment under Korean law.
If you are pulled aside for inspection, customs officers at Incheon are generally professional. Show your documents calmly. The inspection counter near the green “nothing to declare” lane at Terminal 1 (Arrivals Level 1) has English-speaking staff during peak hours (06:00–22:00) — part of what to expect during your first hour in the Korea arrival hall. At Terminal 2, the customs inspection area is directly after baggage claim on the same level.
Insulin and injectable medications: bring a letter from your doctor explicitly stating that you require syringes. Korean customs allows insulin syringes but requires documentation. Sharps containers are sold at most Korean pharmacies (약국, yak-guk) nationwide — a small travel-size container costs around 1,000–2,000 KRW.
Running Out of Medication in Korea: Your Options
If you lose medication or need a refill, Korea has excellent healthcare infrastructure. A visit to a local clinic (의원, ui-won) costs roughly 5,000–15,000 KRW with the national health insurance co-pay, but as a foreign visitor without Korean National Health Insurance (NHIS), expect to pay full price: typically 30,000–80,000 KRW for a consultation depending on the clinic and specialty.
International hospitals with English-speaking staff include:
- Severance Hospital (Sinchon, Seoul) — International Health Care Center, open Mon–Fri 08:30–17:00, tel. 02-2228-5800
- Samsung Medical Center (Irwon-dong, Seoul) — International clinic on the 1st floor of the main building
- Busan St. Mary’s Hospital (Busan) — English interpretation available on request
- Jeju National University Hospital (Jeju City) — serves high volumes of international tourists
After receiving a Korean prescription, take it to any pharmacy (녹십자, CJ Olive Young pharmacies, or independent yak-guk). Common medications like antihistamines, antacids, and basic antibiotics cost 3,000–15,000 KRW per course. Controlled substances cannot be dispensed without a Korean specialist prescription and are subject to daily dispensing limits.

Should You Carry Your Medicine, Ship It, or Buy It Locally?
Once you know the customs rules, the practical question is which approach actually suits your trip: carrying your full supply from home, having a family member courier a top-up mid-trip, or relying on a Korean prescription once you land. Each option has trade-offs that aren’t obvious until you’re standing at a pharmacy counter in Seoul wondering why the staff don’t recognise your brand name.
Carrying your own supply is the right choice for anyone on a stable, well-documented regimen — blood pressure tablets, thyroid hormone, contraceptives, or antidepressants that have a direct or near-equivalent in Korea. It avoids the cost and hassle of a local consultation entirely and means you’re never dependent on a Korean doctor recognising an unfamiliar overseas brand name. The trade-off is bulk: travellers on multiple daily medications for a month-long trip can end up with a surprisingly heavy toiletry bag, and the carry-on liquid rules for Korea flights still apply to liquid or gel-form medicines carried in hand luggage, so pack anything over 100ml in checked luggage with the original box.
Shipping a refill to yourself mid-trip is tempting but rarely worth it. Korean customs treats inbound parcels containing medicine under the same MFDS import rules as personal luggage, and packages get held at the Incheon international mail centre for review — a process that can take 1–2 weeks even when the paperwork is correct. If you’re travelling for longer than 30 days, it is far more reliable to apply for the MFDS import permit before departure and simply pack the full quantity than to gamble on a resupply parcel arriving on time.
Buying locally works well for short-term, non-controlled medications — allergy tablets, reflux medicine, mild pain relief — and is often cheaper than at home even without insurance, since a full course of common generics typically runs 3,000–15,000 KRW (as of 2026 — prices can change, so treat this as a rough guide rather than a quote). It suits travellers who’d rather travel light and top up as needed. It does not suit anyone on a controlled substance, since Korean pharmacies cannot dispense those without a Korean specialist’s prescription and daily quantity limits that are stricter than in many home countries.
One tip rarely mentioned in official guidance: if your medication needs refrigeration (insulin, some biologics), Korean convenience stores such as CU and GS25 will usually let you store a small insulated pouch in their staff fridge for an hour or two if you ask politely at the counter — useful during long KTX transfers between cities when your hotel is hours away. It isn’t an official service, so don’t rely on it for anything beyond a short gap, and always carry a proper insulated travel case as your primary method of temperature control.
