Korean Pharmacies for Foreign Residents: Prescription Drugs, OTC, and English-Friendly Options

Korean pharmacies are fast, well-stocked, and close by, there are roughly 24,000 of them across the country, with most neighbourhoods having 3-5 within walking distance. But the system has specific rules that 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 (십자가) sign. Typical hours:

• Weekdays: 9 AM - 10 PM (9 PM common)
• 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)

일반의약품 (over the counter)

Common OTCs available without prescription at any pharmacy:

Pain and fever

• Tylenol (Acetaminophen / paracetamol)
• Brufen, Ibuprofen, Easy-Prin (ibuprofen)
• Aspirin

Cold and flu

• Pancholdin (종합감기약): multi-symptom cold medicine
• Colgen Kowa
• Amanta
• Cough syrups (including some with dextromethorphan)

Allergy

• Claritin (loratadine)
• Zyrtec (cetirizine)
• Cough-Plus (diphenhydramine, similar to Benadryl)

Digestive

• Gaviscon
• Pepcid (famotidine)
• Pepto Bismol (bismuth subsalicylate): harder to find, substitute with Korean 비위소
• Anti-diarrheal: Smecta, loperamide (sometimes requires pharmacist consultation)

Skin

• Mucogyne (hydrocortisone)
• Baspan (antifungal)
• Fucidin (topical antibiotic, sometimes requires prescription)

Muscle and joint

• Pain patches (파스): Salonpas, Jointrong, Cataflam patches
• Muscle rubs
• Joint cream

안전상비의약품 (convenience store essentials)

A short list of items can be sold at 24-hour convenience stores (CU, GS25, 7-Eleven, Emart24):

• Tylenol (pain/fever)
• 판피린 / 판콜에이 (cold medicine)
• 베아제 / 훼스탈 (digestives)
• 제일쿨파프 (muscle rub)
• Tiger Balm variants

This is NOT a complete pharmacy substitute. For anything beyond these, you need an actual 약국.

Late-night and emergency pharmacies

Most pharmacies close at 10 PM. For after-hours needs:

Safety essential medicines at 24/7 convenience stores

As above. Sufficient for mild fever, cold onset, muscle soreness.

심야약국 (late-night pharmacy)

Every Korean city and district has designated 심야약국 that stay open until midnight or 2 AM, some 24/7. They rotate branches by district.

To find the nearest open pharmacy:

• Call 1339 (Ministry of Health line): ask "심야약국 어디 있나요?"
• Check e-gen.or.kr, emergency portal that lists open pharmacies
• Use the 응급의료정보제공 app (E-Gen app) for the same data
• In Seoul: 서울시 약국 정보 (Seoul city pharmacy information) on the city website

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: 20-40% of the medication cost (depends on medication tier)
• Dispensing fee: ₩400-₩2,000 per prescription (flat)
• Typical total for a 30-day supply of an SSRI: ₩5,000-₩10,000
• Typical total for a 10-day course of antibiotics: ₩3,000-₩8,000

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

Without NHIS

If you are a tourist, a brand-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.

The pharmacy visit: what to expect

For a prescription fill

1. Receive the 처방전 from your doctor (printed, two copies: one for pharmacy, one for your records)
2. Walk into any 약국, no appointment needed
3. Hand over the 처방전 and your NHIS card
4. Pharmacist counsels you: dosing, timing, potential side effects. This is required by law.
5. Pay your copay. Credit card accepted almost everywhere.
6. Leave with your medication plus a printed medication guide.

Time: 5-15 minutes depending on queue.

For an OTC purchase

1. Walk into pharmacy
2. Describe your symptom to the pharmacist (in Korean if possible; in English at foreigner-heavy areas like Itaewon, Hannam)
3. Pharmacist recommends product; hands you options
4. Pay cash or card
5. 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 directory listings, Seoul Global Center maintains a list of English-friendly pharmacies. Search "English-speaking pharmacy Seoul" for community recommendations.

Bringing medication into Korea

Personal use guidelines:

• Up to 3 months supply: generally allowed if you carry a doctor's note (English is fine) and original packaging

• Amphetamines (Adderall, Vyvanse, Dexedrine): prohibited regardless of prescription
• Cannabis-based (including most CBD): prohibited
• Injectable medications (insulin, some biologics): allowed with prescription; declare at customs

Always carry:

• 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.

2. Save 1339 in your phone for after-hours medication needs.
3. Download the E-Gen app for emergency pharmacy location on the go.
4. If you take regular medication: schedule a visit with a Korean doctor to transition your prescription to a Korean-available equivalent before running out.
