Korean Medicine vs Japanese Medicine: Banned Items & Swaps

## Korean medicine vs Japanese medicine: what actually changes when you cross over If you are hopping from Tokyo to Seoul and wondering whether to stock up at Don Quijote first, here is the short answer. Korean medicine and Japanese medicine cover the same symptoms with different brand names, and a few Japanese drugstore favourites are now illegal to bring into Korea. The most famous example is EVE, the pink-box painkiller. Since April 2025 the Korea Customs Service has treated most EVE products as controlled substances because they contain allylisopropylacetylurea, a sedative that Korea classifies as a psychotropic drug. Bring it in and it gets confiscated, plus you fill out a violation report. So the safer plan is simple - buy your Korean medicine in Korea, where a pharmacy sits on almost every block and pharmacists are trained to match a Korean medicine to your symptoms without an appointment. I have done the Japan-then-Korea trip four times now, and each time I learned something the hard way. Let me save you the trouble. ## Which Japanese medicines are banned or restricted in Korea? The main problem ingredient is allylisopropylacetylurea, found in EVE A, EVE Quick and EVE Quick DX. Korea's Narcotics Control Act Enforcement Decree lists it as a psychotropic substance, so importing or possessing it is prohibited. The Korea Customs Service added EVE to its watch list in April 2025 after a rise in travellers carrying it in. One product in that family is the exception - EVE Three Shot Premium uses only ibuprofen, acetaminophen, caffeine and magnesium oxide, with no sedative. But honestly, standing at customs trying to explain which box is which is not how you want to start a trip. | Japanese product | Status in Korea | What to buy in a Korean pharmacy instead | | --- | --- | --- | | EVE A / EVE Quick | Banned (contains allylisopropylacetylurea) | Easy-N Six (이지엔6), ibuprofen soft capsules | | Loxonin S (loxoprofen) | Prescription-only in Korea | Naproxen or ibuprofen OTC, ask the pharmacist | | Motilium-M (domperidone) | Prescription-only in Korea | Bearse (베아제) or Festal (훼스탈) for indigestion | | Salonpas / Loxonin Tape | Fine to carry, easy to replace | Ketotop, Trast patch, Shinshin Pas | | Cabagin Kowa | Fine to carry, easy to replace | Bearse, Doctor Bearse, Festal Plus | A note on quantity. Personal-use amounts of ordinary Japanese medicine are generally fine, but "personal use" means a trip's worth, not a suitcase. If you are carrying more than a couple of boxes of anything, expect questions. ## Is Korean medicine stronger or weaker than Japanese medicine? Korean medicine tends to be dosed closer to Western strengths, while Japanese OTC formulas are often deliberately milder. That is the single biggest practical difference people notice. A Japanese cold remedy usually blends several ingredients at gentle doses. A Korean pharmacist is more likely to hand you a targeted product at a standard adult dose. Take painkillers, the category where the Korean medicine and Japanese medicine gap is most visible. In Japan you will see a lot of combination tablets with caffeine and a sedative. In Korea the shelf is dominated by single-ingredient options - Tylenol for acetaminophen, Easy-N Six for ibuprofen, Naproxen products for longer-lasting relief. Geworin and Saridon-A exist as combination options, but the default advice from a Korean pharmacist is usually the simpler one. The other difference is the buying experience. Japan splits things between full pharmacies and drugstores, and the drugstore staff may not be a licensed pharmacist. In Korea, every 약국 (yakguk) is staffed by a licensed pharmacist, full stop. You describe your symptom, they pick the product, and you pay. There is no self-service aisle of Korean medicine to browse, which surprises a lot of first-timers.

Korean pharmacies usually close between 7pm and 8pm, and many shut entirely on Sundays and holidays. After hours you have two options - a designated late-night pharmacy, or the 13-item safety medicine list at any 24-hour convenience store. That convenience store list of Korean medicine is fixed by law and identical at CU, GS25, 7-Eleven and Emart24. It covers: - Tylenol products (acetaminophen, for pain and fever) - Two cold remedies - Pancol-A (판콜에이) and Panpyrin-T (판피린티) - Four digestive aids - Bearse, Doctor Bearse, Festal Gold, Festal Plus - Two pain patches - Jeil Cool Pap (제일쿨파프) and Shinshin Pas Arex (신신파스아렉스) That is it. No antihistamines, no cough syrup, no antibiotics. For anything else you need a late-night pharmacy (심야약국, simya yakguk), typically open until around 1am. As of 2026 there are roughly 240 of them nationwide with about 39 in Seoul. You can call 1339, the multilingual health information line, or check e-gen.or.kr to find the closest one open right now. And one rule that catches almost every foreign visitor - all antibiotics in Korea are prescription-only. If you are used to buying amoxicillin over the counter somewhere else, that will not work here. You see a doctor, get a printed 처방전 (prescription), and take it to any pharmacy. ## What I learned carrying medicine between Japan and Korea Here is the trip that taught me the most. In late 2025 I flew Osaka to Incheon with a Don Quijote haul that included two boxes of EVE Quick for my partner's migraines. I genuinely did not know about the ban. Customs pulled the bag, found the boxes, and the officer was polite but firm - the medicine was confiscated, I filled out a short report, and it went on my record. Total cost was about 1,800 yen of product and forty minutes of my life. Not a disaster, but avoidable. The next morning I walked into a pharmacy near Hongdae, said "두통약 주세요" (headache medicine please), and walked out ninety seconds later with a box of ibuprofen soft capsules for around 5,000 won. It worked exactly as well. That was the moment I stopped treating Japanese medicine as irreplaceable and started trusting Korean medicine to fill the same gap. A few other things I picked up along the way. Korean medicine is often sold as a small blister of 4 to 10 tablets rather than a 200-count bottle, which is perfect for a short trip and much cheaper than it sounds. Prices for basic Korean medicine are low - most common OTC items land between 3,000 and 12,000 won. And pharmacists near tourist districts like Myeongdong, Hongdae and Itaewon frequently speak enough English to handle a symptom conversation, though pointing at the body part that hurts works everywhere. There is a fair counter-argument to all of this, and I want to be honest about it. If a specific Japanese product genuinely works for you and has no restricted ingredient, there is no reason to abandon it. Cabagin, Salonpas, most Japanese eye drops - carry them, they are fine. The point is not that Korean medicine is superior. It is that a Korean medicine equivalent almost always exists here, so there is no need to risk a customs problem over a box you can replace for a few thousand won. One last practical tip. Keep medicine in original packaging with the ingredient list visible. Loose pills in a pill organiser are far more likely to trigger a question at the border, and you will not be able to prove what they are. ## Frequently asked questions

Can I bring Japanese medicine into Korea for personal use?

Yes, for most products, in reasonable personal quantities. The exception is anything containing a controlled ingredient - most notably allylisopropylacetylurea in EVE painkillers, which has been prohibited since April 2025. Keep items in original packaging and carry only what you need for the trip.

What is the Korean equivalent of EVE painkiller?

Ask a Korean pharmacy for ibuprofen, sold most commonly as Easy-N Six (이지엔6). For period pain specifically, pharmacists often suggest ibuprofen or naproxen. Tylenol (acetaminophen) is the alternative if you cannot take NSAIDs. All of these Korean medicine options are available without a prescription.

Do Korean pharmacists speak English?

Many do in tourist areas such as Myeongdong, Hongdae, Itaewon and Gangnam, though it varies. Showing a translated symptom on your phone works reliably when you are asking for a specific Korean medicine. The multilingual health line 1339 can also help you locate an open pharmacy and explain your situation.

Is Korean medicine cheaper than Japanese medicine?

Usually yes for basic OTC items. Common Korean medicine such as painkillers, cold remedies and digestive aids typically costs 3,000~12,000 won, partly because pharmacies sell small quantities rather than large bottles. Japanese drugstores can be cheaper for bulk supplements and skincare.

Where can I buy medicine in Korea at 3am?

Any 24-hour convenience store stocks the 13 legally designated safety medicines - Tylenol, two cold remedies, four digestive aids and two pain patches. For anything else, find a late-night pharmacy (심야약국) via 1339 or e-gen.or.kr. Roughly 240 operate nationwide, with about 39 in Seoul.
