How to Read Korean Medicine Labels: Dosage, Warnings & Expiry

## The Five Korean Words That Tell You Everything on a Medicine Box If you only memorize five things from this guide, make them these: 일반의약품 (OTC), 효능·효과 (what it treats), 용법·용량 (how much and how often), 사용상의 주의사항 (warnings), and 사용기한 (expiry date). Every Korean medicine label prints these in the same order, in the same places, on almost every box sold in a Korean pharmacy. Once you can find those five blocks, a Korean medicine label stops being a wall of Hangul and becomes a form you already know how to read. Below I break down an actual Korean medicine label from a box I bought, translate the dosage phrases you will actually see, and show you the government database that tells you what a loose pill is when the box is long gone. ## What Is Actually Printed on a Korean Medicine Label? A Korean medicine label is legally required to carry the product name, classification, active ingredients, indications, dosage, precautions, storage conditions, lot number, and expiry date. That list comes from the Ministry of Food and Drug Safety labeling regulation, so the same Korean medicine label structure holds whether you buy a 3,000 won antacid or an imported painkiller. Here is the thing nobody tells you before you land. Korean pharmacies do not hand you a paper leaflet in English the way many European pharmacies do. The box itself is the leaflet. The tiny folded insert inside, called the 첨부문서, repeats everything in denser type. So learning to scan a Korean medicine label is not optional if you want to dose yourself safely. The very first thing to check is the classification line, usually printed in a small colored bar at the top corner: | Korean term | Romanization | What it means | Why you care | |---|---|---|---| | 일반의약품 | ilban-uiyakpum | Over-the-counter | You can buy it at any pharmacy, no prescription | | 전문의약품 | jeonmun-uiyakpum | Prescription only | A pharmacist legally cannot sell it to you without a script | | 안전상비의약품 | anjeon-sangbi-uiyakpum | Convenience store item | Sold 24/7 at CU, GS25, 7-Eleven | | 의약외품 | uiyak-oepum | Quasi-drug | Not a medicine. Think medicated patches, mouthwash | I once spent twenty minutes in a Jongno pharmacy convinced the pharmacist was refusing to sell me something out of stubbornness. The box I had photographed online said 전문의약품. She was not being difficult. She was following the law. ## How Do You Read the Dosage Line on a Korean Medicine Label? Korean dosage instructions follow a fixed pattern: frequency per day, then quantity per dose, then timing relative to meals. Read any Korean medicine label left to right and the dosage line decodes cleanly. "1일 3회 1회 1정 식후 30분 복용" means three times a day, one tablet each time, taken 30 minutes after meals. Break the pieces apart and you can handle any variation: - 1일 3회 - three times per day. Swap the number for 1회 or 2회 as printed. - 1회 1정 - one tablet per dose. 정 is tablet, 캡슐 is capsule, 포 is a powder sachet, mL appears for syrups. - 식후 30분 - 30 minutes after a meal. This is the default on most Korean medicine labels. - 식전 - before eating. Common on stomach motility drugs. - 식간 - between meals, meaning roughly two hours after eating. Not "with food." - 취침 전 or 자기 전 - before bed. - 공복에 - on an empty stomach. The 식후 30분 convention deserves a note because it confuses a lot of visitors. Korean pharmacists use it as a standard partly to protect the stomach lining and partly because tying doses to meals makes people remember them. It is a habit of practice more than a hard pharmacological rule, and Korean health authorities have publicly said some drugs work better taken at other times. If a pharmacist tells you something different from the box, follow the pharmacist. Age limits sit right underneath the dosage line on a Korean medicine label. Look for 만 15세 이상 (ages 15 and over), 소아 (children), 7세 미만 (under 7). Korean age limits on a medicine label use 만, which means the international age count, not the old Korean age system. ## Which Warnings Should You Actually Stop and Read? Scan the 사용상의 주의사항 block for four phrases: 졸음, 음주, 임부, and 운전. Those four cover the Korean medicine label warnings most likely to ruin your day as a traveler. - 졸음이 올 수 있음 - may cause drowsiness. Extremely common on Korean cold and allergy medicine, because first-generation antihistamines are still widely used in Korean OTC combination products. - 음주 금지 or 금주 - do not drink alcohol. - 운전이나 기계 조작 주의 - caution when driving or operating machinery. - 임부·수유부 - pregnant or breastfeeding women. - 고혈압, 녹내장, 전립선 비대 - hypertension, glaucoma, enlarged prostate. These show up as contraindications on decongestant-containing cold remedies. There is one dosage difference that genuinely catches people out. Korean OTC acetaminophen typically starts at 500mg per tablet, while the standard US over-the-counter tablet is 325mg. If you take "two tablets, like at home" without checking the 함량 (content per tablet) line, you have just taken 1,000mg instead of 650mg. That is still within normal adult dosing, but it stacks fast if you are also taking a cold combination product that already contains acetaminophen. I check the 함량 number on every box now, and it takes about three seconds. For a deeper breakdown of the brands involved, our [Korean painkillers OTC guide](https://beautydir.co/korean-painkillers-otc-tylenol-gaebolin-brufen-guide) walks through Tylenol, Gaebolin and Brufen side by side. ## How Do You Read Expiry Dates and Storage on Korean Packaging? Look for 사용기한 or 유효기간 followed by a date, usually written year, month, day, and often ending in 까지, which means "until." So 사용기한 2028.05.31 까지 means usable until 31 May 2028. Two more date words show up on a Korean medicine label and they are not the same thing: - 제조일자 - date of manufacture. Not the expiry. - 개봉 후 - after opening. When a syrup or eye drop says 개봉 후 1개월, the clock starts the day you break the seal, regardless of the printed expiry. That second one matters more than people expect. I kept a bottle of Korean eye drops for a full year because the printed date said 2027, then noticed the 개봉 후 line said one month. Eye drops and multi-dose syrups are the usual offenders. Storage lines are short and easy: - 실온 보관 - room temperature, defined in Korean pharmacopoeia terms as 1 to 30 degrees Celsius. - 서늘한 곳에 보관 - store in a cool place. - 냉장 보관 - refrigerate. - 직사광선을 피하고 - avoid direct sunlight. Korean summers run hot and humid, so if a box says 실온 보관 and you are leaving medicine in a car in August, you are outside the label conditions. ## What If You Only Have Loose Pills and No Box? Korean pharmacies often dispense pills in small sealed paper packets called 약포지, with no box and no label, so the government runs a public pill identification database for exactly this situation. This is probably the single most useful thing in this article, because it recovers the entire Korean medicine label from a pill alone. Every tablet and capsule legally sold in Korea carries an identification marking, regulated separately from the Korean medicine label itself. You can look it up: 1. Go to the MFDS drug portal at [의약품안전나라](https://nedrug.mfds.go.kr/searchDrug). 2. Choose the 낱알 (individual pill) search rather than text search. 3. Enter the imprint code, then select shape and color from the dropdowns. 4. The result gives you the product name, manufacturer, and full label content. The [Korea Pharmaceutical Information Center](https://www.pharm.or.kr/search/drugidfy/) runs a parallel pill identification search that some people find easier to use. Both are in Korean, but the forms are mostly dropdowns and images, so a browser translation handles them fine. Here is how it played out for me. A friend left a strip of white oval tablets in my bag after a hiking trip and I had no idea what they were. Imprint code, white, oval, three dropdown clicks, and the database returned a common Korean muscle relaxant with the full dosage line. Total time was under two minutes. ## Three Habits That Make Korean Medicine Labels Easy After a couple of years of reading Korean medicine labels here, these are the habits that actually stuck. Photograph the box before you throw it away. The 효능·효과 and 용법·용량 blocks are what you will want at 2am, and the box is usually already in a bin at that point. Ask for the 성분명, not the brand name. Korean brand names rarely match what you know from home. The ingredient name is printed on the box and pharmacists will write it down for you if you ask. Knowing a few phrases helps here, and our [what to say at a Korean pharmacy](https://beautydir.co/what-to-say-korean-pharmacy-phrases-prescription-rules) guide covers the exact sentences. Use your camera translation on the warnings block, not the whole box. Translating an entire Korean medicine label produces a soup of pharmacological terms. Point it at 사용상의 주의사항 only and you get something readable. A fair caveat to close on. Camera translation still stumbles on Korean medical compound nouns, and a mistranslated contraindication is worse than no translation at all. If you have a chronic condition, take regular prescription medication, are pregnant, or are buying for a child, show the pharmacist your existing medication and ask directly. Korean pharmacists are trained to counsel on OTC selection, and most in central Seoul handle basic English comfortably. Reading a Korean medicine label well is a tool for confidence, not a substitute for asking. ## Frequently Asked Questions

How do I know if a Korean medicine is over-the-counter or prescription only?

Look for the classification printed in a small box near the top of the package. 일반의약품 means over-the-counter and you can buy it at any pharmacy. 전문의약품 means prescription only and a pharmacist cannot legally sell it without a doctor's prescription. 안전상비의약품 means it is one of the limited items also sold at convenience stores around the clock.

What does 1일 3회 식후 30분 mean on a Korean medicine label?

On a Korean medicine label it means take the medicine three times a day, 30 minutes after each meal. 1일 3회 is the frequency, and 식후 30분 is the timing. The quantity per dose appears next to it as something like 1회 1정, meaning one tablet per dose. Substitute the numbers as printed on your specific box.

Where is the expiry date on Korean medicine packaging?

Look for 사용기한 or 유효기간, usually on the side panel or the bottom flap, printed as year.month.day and often followed by 까지 meaning "until." Do not confuse it with 제조일자, which is the manufacturing date. If the product says 개봉 후 followed by a number of months, that period starts when you open it.

Do Korean medicine labels come in English?

A Korean medicine label is almost never printed in English on domestic products. Korean labeling regulations require the mandatory information in Korean, and imported products sold through Korean pharmacies carry a Korean overlabel. A few products aimed at travelers add English, but you should plan to read the Korean or use camera translation on the key blocks.

How can I identify a Korean pill with no packaging?

Use the pill identification search on the MFDS portal at nedrug.mfds.go.kr or the Korea Pharmaceutical Information Center site. Enter the imprint code stamped on the tablet, then pick the shape and color. Every tablet and capsule legally sold in Korea carries a required identification marking, so the search usually returns an exact match.

Is Korean OTC painkiller dosage stronger than in the US?

Per tablet, often yes. Korean over-the-counter acetaminophen commonly comes as 500mg tablets, while the standard US over-the-counter tablet is 325mg. Check the 함량 line on the box for the amount per tablet before you assume your usual two-tablet habit transfers directly.
