Korea has roughly 25,000 pharmacies (약국) across the country, with most neighbourhoods having several within walking distance. The system is fast and well-stocked, but specific rules trip up foreign residents: what is OTC versus prescription, what is sold at convenience stores, what requires ID, and how late-night care works. This guide walks through each.
How the system is structured
Since 2000, Korea has enforced 의약분업 (separation of prescribing and dispensing). That means:
- Doctors prescribe at clinics (의원) and hospitals. They do not dispense medication.
- Pharmacists dispense at pharmacies (약국). They do not prescribe.
For prescription medications, you always do two things: see a doctor, then visit a pharmacy. For OTC items, you go directly to a pharmacy or, for a short list, a 24-hour convenience store.
Physical layout
Korean pharmacies are standalone storefronts, often with a green cross sign. Typical hours:
- Weekdays: 9 AM - 8 or 9 PM (some near hospitals open until 10 PM)
- Saturdays: 9 AM - 5 PM
- Sundays: closed (most), some open noon-6 PM
- Public holidays: closed
Inside, the pharmacist works behind a counter with a small consultation area. Prescriptions are filled in 5-15 minutes. OTC items can sometimes be self-selected from a shelf, but at most pharmacies you ask the pharmacist by naming your symptom.
Prescription vs OTC: the basic split
전문의약품 (prescription only)
Examples of what needs a prescription in Korea:
- All antibiotics (amoxicillin, azithromycin, etc.)
- All controlled psychiatric medications (SSRIs, SNRIs, benzodiazepines, stimulants)
- Most sleep medications (zolpidem, etc.)
- Pseudoephedrine (Sudafed), requires ID
- Codeine-containing products (some cough syrups)
- Strong painkillers (tramadol, stronger opioids)
- Most blood pressure, cholesterol, diabetes medications
- Oral contraceptives (in most cases, though some generics are OTC)
- Anti-acne treatments (tretinoin, isotretinoin)
- Strong allergy medications (some nasal steroids)

안전상비의약품 (convenience store essentials)
A fixed list of 13 items can be sold at 24-hour convenience stores (CU, GS25, 7-Eleven, Emart24). This list has been in place since 2012:
Pain and fever (5)
- Tylenol 500mg (타이레놀정 500mg)
- Tylenol 160mg (타이레놀정 160mg)

This is NOT a complete pharmacy substitute. For anything beyond these 13 items, you need an actual 약국.
Late-night and emergency pharmacies
Most pharmacies close between 8 and 9 PM. For after-hours needs:
Safety essential medicines at 24/7 convenience stores
As above. Sufficient for mild fever, cold onset, muscle soreness.
Late-night and holiday pharmacies
Two separate systems cover after-hours and holiday needs, and it helps to know both names so you can search correctly:
- Public night pharmacies (공공심야약국): a government-funded network typically open from 10 PM to 1 AM. Coverage is limited and not every district has one, so check before you travel.
- Holiday-watch pharmacies (휴일지킴이약국): a separate pharmacist-association rotation that covers Sundays, public holidays, and evenings from around 6 PM.
True 24/7 pharmacies are rare. The realistic late-night window runs to about 1 AM, with the hospital ER as the fallback after that.
To find the nearest open pharmacy:
- Call 1339 (KDCA health information line, multilingual): ask "심야약국 어디 있나요?"
- Check e-gen.or.kr, emergency portal that lists open pharmacies
- Check pharm114.or.kr, the holiday-watch pharmacy (휴일지킴이약국) locator
- Use the 응급의료정보제공 app (E-Gen app) for the same data
Emergency medication at ERs
If you need a prescription for an emergency (severe asthma, urgent antibiotic need, seizure medication) outside pharmacy hours, the hospital ER will prescribe and dispense. See our ER guide.
NHIS coverage at the pharmacy counter
Most Korean prescription medications are on the NHIS formulary. With your NHIS card and a valid 처방전:
- Copay: a flat 30% of the medication cost for general adult patients (lower for infants, children under 6, and some seniors aged 65 and over)
- Dispensing fee: a tiered dispensing-fee bundle set by NHIS, of which you pay 30%, so your patient-facing portion usually lands between ₩1,700 and ₩2,500 per prescription for a short course
- Typical costs vary by drug, generic versus branded, and dosage. Use the HIRA pharmacy cost calculator to estimate your own. Generic prescriptions on the formulary are inexpensive; imported brand-name drugs and non-formulary therapies cost more, often a lot more.
What's NOT covered
- Brand-name imports when a Korean generic exists (you pay full price or the price difference)
- Cosmetic dermatology products (topical retinoids marketed for acne/wrinkles)
- Some elective treatments (IVF drugs, rare disease medications sometimes covered via separate channels)
- Non-Korean-approved medications brought in on special permission
NHIS coverage also requires both the prescribing facility and the dispensing pharmacy to be NHIS-contracted (요양기관). Almost all are, but some private or cosmetic clinics are not, so confirm before you assume a prescription is covered.
Without NHIS
If you are a tourist, a new arrival without NHIS yet, or a short-term visitor, you can still fill a Korean prescription but pay the full cash price (3-5x the NHIS copay). Keep receipts for any travel insurance claim.
Western medications: common substitutes
If you arrived in Korea on a specific home-country medication, here is what to expect:
Pain and fever
- Tylenol → Tylenol, 타이레놀 (OTC)
- Advil / Motrin → Brufen, Ibuprofen (OTC)
- Aspirin → Aspirin, 아스피린 (OTC)
- Excedrin → no direct equivalent; combine Tylenol + Aspirin + Caffeine manually
Allergy and cold
- Claritin (loratadine) → Clarityne, Claritin (OTC)
- Zyrtec (cetirizine) → Zyrtec (OTC)
- Allegra (fexofenadine) → Allegra Tab 120mg is OTC in Korea (approved as 일반의약품 in 2022). The fexofenadine + pseudoephedrine combination (Allegra-D) follows different rules because of the pseudoephedrine.
- Benadryl (diphenhydramine) → sold mainly as an OTC sleep aid (단자민정); ask the pharmacist for a diphenhydramine sleep aid (수면유도제)
- Sudafed (pseudoephedrine) → Rx + ID required in Korea
- Flonase, Nasonex (nasal steroids) → Rx in Korea
Digestive
- Pepcid (famotidine) → Pepcid (OTC)
- Nexium, Prilosec (PPIs) → Rx in Korea typically
- Imodium (loperamide) → OTC but pharmacist consultation
- Tums (calcium carbonate) → easy to find, various brands
Other common
- Sleep aids (melatonin) → synthetic melatonin is Rx-only in Korea (registered for short-term insomnia in patients 55 and over, as a 2mg sustained-release tablet). The US-style OTC melatonin supplement is not available in Korean pharmacies. OTC sleep alternatives are diphenhydramine-based products (단자민정) and herbal sleep aids.
- Birth control → most Rx; some emergency contraception (Postinor, 72시간 피임약) is Rx with walk-in consultation
- Erectile dysfunction (Viagra) → Rx
- Minoxidil (hair loss) → topical minoxidil solution (마이녹실, 동성 미녹시딜액) is OTC at any pharmacy, same as the US. Oral minoxidil tablets are Rx (used off-label for hair loss; the registered indication is high blood pressure).
What you CANNOT get in Korea
- Adderall, Vyvanse, Dexedrine (amphetamine-based stimulants): prohibited
- CBD products: classified as cannabis; most prohibited
- Some newer antidepressants not yet approved in Korea
- Certain US-approved prescription painkillers with formulations not registered in Korea
If your medication is unavailable, schedule a visit with a Korean doctor 1 to 2 months before you run out to discuss substitutes.
The pharmacy visit: what to expect
For a prescription fill
- Receive the 처방전 from your doctor (printed, two copies: one for pharmacy, one for your records)
- Walk into any 약국, no appointment needed
- Hand over the 처방전 and your NHIS card
- Pharmacist counsels you: dosing, timing, potential side effects. This is required by law.
- Pay your copay. Credit card accepted almost everywhere.
- Leave with your medication plus a printed medication guide.
Time: 5-15 minutes depending on queue.
For an OTC purchase
- Walk into pharmacy
- Describe your symptom to the pharmacist (in Korean if possible; in English at foreigner-heavy areas like Itaewon, Hannam)
- Pharmacist recommends product; hands you options
- Pay cash or card
- Basic instructions given verbally
Pharmacists in Korea are well-trained and often give better advice on minor ailments than a general practitioner. Use them as your first line for common issues.
English-speaking pharmacies
Some pharmacies in foreigner-heavy areas have English-capable staff. Ask before you go:
Seoul
- Itaewon, Hannam: multiple pharmacies with English-speaking staff; some have English-labeled shelves
- Gangnam (Apgujeong, Sinsa): larger modern pharmacies often have English-speaking pharmacists
- Yongsan, near US Army base: some pharmacies cater specifically to US military families
- Seoul Station area: some pharmacies accept international clientele
Other cities
- Pharmacies inside or near major hospital international clinics (Asan, Samsung, Severance) typically have English capability
- Foreign-resident-heavy areas (Pyeongtaek, Pohang, Busan Haeundae) have individual English-friendly branches
For recommendations, search "English-speaking pharmacy Seoul" or ask in foreign-resident community groups, and confirm by phone before you go. If you need a doctor for a prescription first, Seoulstart's healthcare directory lists English-speaking clinics and hospitals by district.
Common scenarios
You have a cold at 11 PM
- Go to 24-hour convenience store (CU, GS25, 7-Eleven)
- Buy Pancholdin (cold medicine) and Tylenol
- If symptoms worsen overnight, go to a 24-hour ER or wait for morning
You need antibiotics
- See a doctor at any 의원 (walk-in, 10-30 min wait typical)
- Get 처방전
- Fill at any pharmacy same day
- The doctor visit and the medication are both NHIS-covered, so your out-of-pocket total is modest
You arrived on Adderall
- Do NOT try to fill your US prescription in Korea (it will not work)
- Book a psychiatry appointment at a major hospital or private English-speaking clinic
- Plan for 2 to 4 weeks of diagnostic re-evaluation
- Likely substitution: methylphenidate (Concerta)
- See our mental health care guide for detail
You need birth control
- Visit any OB/GYN clinic (or a general practice clinic)
- Discuss preferences and health history
- Get a 처방전
- Fill at any pharmacy; an NHIS-covered monthly supply is inexpensive
- Note: emergency contraception (morning-after pill) is prescription-only in Korea but accessible same-day walk-in
You need allergy medication during pollen season
- OTC: Zyrtec, Claritin, Allegra 120mg at any pharmacy
- If OTC insufficient: see a doctor for stronger prescriptions (nasal steroids)
You need to refill a home-country prescription
- Book an appointment with a Korean doctor
- Bring a summary of your home-country prescription (generic name, dose, duration)
- The doctor will either prescribe the same, a Korean equivalent, or a substitute
- First-time visits for controlled substances may require bloodwork or diagnostic confirmation
Bringing medication into Korea
Personal use guidelines:
- General (non-controlled) prescription drugs: bring a reasonable personal-use quantity (typically interpreted as 3 to 6 months) if you carry a doctor's note (English is fine) and original packaging
- Controlled substances (benzodiazepines, zolpidem, opioids, methylphenidate): you must apply for self-treatment import approval (자가치료용 마약류 휴대 입출국) from the 식약처 마약정책과 at least 10 business days before arrival, online at nedrug.mfds.go.kr (phone 043-719-2813). Bringing them in without approval is a criminal offense, not a paperwork issue. This is especially important for arrivals carrying chronic-condition medication such as Tramadol from their home country.
- Amphetamines (Adderall, Vyvanse, Dexedrine): prohibited regardless of prescription
- Cannabis-based (including CBD and hemp oil): prohibited regardless of any foreign prescription
- Injectable medications (insulin, some biologics): allowed with prescription; declare at customs
Always carry:
- Original packaging with pharmacy label
- Doctor's note stating diagnosis and prescription
- Letter from your pharmacist or doctor translated into English
- Passport and ARC (or visa on arrival)
If stopped at customs, cooperate fully. Most declared medications pass without issue.
Tips specific to foreign residents
- Build a relationship with one pharmacy near home. They remember you, know your allergies, and can advise on interactions.
- Google Translate works for medications. Point at the package and translate labels before buying.
- Keep prescription records. Save 처방전 copies; take photos. Useful for year-end tax deduction (의료비) and for continuity if switching doctors.
- Ask the pharmacist about drug interactions. They are trained professionals and their advice is free.
- Learn a few Korean symptom phrases. "두통 (headache)", "배탈 (upset stomach)", "기침 (cough)", "콧물 (runny nose)" get you far.
- Keep a basic first aid kit. Korean brands for common needs: 베타딘 (Betadine, antiseptic), Band-Aids (밴드), 파스 (muscle patches), 아이스팩.
What to do next
- Find your nearest pharmacy (약국 in Google Maps or Naver Maps). Note its hours.
- Save 1339 in your phone for after-hours medication needs.
- Download the E-Gen app for emergency pharmacy location on the go.
- If you take regular medication: schedule a visit with a Korean doctor to transition your prescription to a Korean-available equivalent before running out.
- Bookmark this guide and our ER guide for when something urgent happens.
