Korean Pharmacies: Prescriptions, OTC Medicine & Hours

Using a pharmacy is a basic part of everyday life in Korea, but the system may feel unfamiliar when you first arrive.

Table of Contents

You may visit a pharmacy after seeing a doctor, or you may go directly to one for a minor health problem. The main challenge for many foreign residents is understanding:

Which medicines require a prescription
Which medicines can be purchased directly
Why familiar international brand names may be unavailable
How Korean prescription packaging works
Where to find medicine at night or on a public holiday

The process becomes much easier when you focus on the right information: the active ingredient, strength, dosage form, and instructions.

Quick answer: Prescription-only medicine in Korea generally requires a prescription from a doctor or dentist. Over-the-counter medicine can be purchased directly from a pharmacy, usually after speaking with a pharmacist. Convenience stores sell only a limited list of officially designated medicines.

The Basic Structure of the Korean Pharmacy System

Korea generally separates the roles of prescribing and dispensing medicine.

In a typical outpatient situation:

A doctor or dentist examines the patient.
The medical provider issues a prescription when prescription medicine is needed.
The patient takes the prescription to a pharmacy.
A pharmacist dispenses the medicine and explains how to use it.

There are legal exceptions in which medicine may be dispensed directly within a medical institution, but foreign residents will most commonly experience the clinic-to-pharmacy process described above.

Korea’s Pharmaceutical Affairs Act defines a pharmacy as a place where a licensed pharmacist or Korean medicine pharmacist prepares medicine for patients. The law also distinguishes over-the-counter medicine from prescription-only medicine and defines medication counseling as providing information about names, dosage, effects, storage, side effects, and interactions.

Essential Korean Pharmacy Vocabulary

Pharmacy: 약국

A pharmacy is called yakguk (약국) in Korean.

Look for a sign containing:

약국
약
Pharmacy

Many pharmacies are located near clinics and hospitals because patients frequently visit them immediately after receiving a prescription.

Pharmacist: 약사

A pharmacist is called yaksa (약사).

A Korean pharmacist can:

Dispense medicine according to a valid prescription
Explain how and when to take medicine
Provide information about side effects and interactions
Help customers select an appropriate OTC product
Advise a customer to visit a clinic when medical evaluation is necessary

A pharmacist can discuss symptoms to help you select an OTC product, but pharmacists do not normally make a medical diagnosis.

Prescription: 처방전

A prescription is called cheobangjeon (처방전).

It is a document issued by a doctor or dentist that normally includes:

The patient’s information
The prescribed medicine
The strength and dosage
The number of treatment days
Directions for use
The prescription’s permitted usage period

A prescription is not the medicine itself. You must take it to a pharmacy to have the medicine dispensed.

Over-the-Counter Medicine: 일반의약품

OTC means over the counter.

The Korean legal category is called ilban uiyagpum (일반의약품), meaning general medicine.

Under the Pharmaceutical Affairs Act, this category includes medicine that can generally be used without a doctor’s or dentist’s prescription and has relatively low risks of misuse or serious adverse effects when used correctly.

Examples may include certain products for:

Headaches or mild fever
Cold symptoms
Indigestion
Diarrhea or constipation
Mild allergies
Muscle pain
Minor skin irritation
Small cuts or burns

The classification applies to individual products. Two medicines used for similar symptoms may not necessarily belong to the same legal category.

Prescription-Only Medicine: 전문의약품

Prescription-only medicine is called jeonmun uiyagpum (전문의약품).

Under Korean law, medicines that are not classified as OTC medicines fall into the prescription-medicine category.

You cannot normally purchase these medicines simply by requesting them at the counter. A doctor’s or dentist’s prescription is generally required.

Safe and Readily Available Medicine: 안전상비의약품

Anjeon sangbi uiyagpum (안전상비의약품) refers to a limited group of medicines that may be sold outside pharmacies by properly registered retailers.

These are often called convenience-store medicines, but not every convenience store is automatically authorized to sell them.

After-Hours Pharmacy

An after-hours pharmacy is a pharmacy that operates during evenings, late-night hours, weekends, or public holidays.

Related Korean terms include:

휴일지킴이약국 — holiday or duty pharmacy
심야약국 — late-night pharmacy
공공심야약국 — public late-night pharmacy
연중무휴약국 — pharmacy open throughout the year

These labels do not necessarily mean that a pharmacy is open 24 hours.

Prescription Medicine vs. OTC Medicine in Korea

Category	Korean term	Prescription required?	Where it is obtained
Prescription medicine	전문의약품	Generally yes	Licensed pharmacy
OTC medicine	일반의약품	No	Licensed pharmacy
Designated convenience-store medicine	안전상비의약품	No	Registered retailers and pharmacies
Health functional food	건강기능식품	No	Pharmacies and other retailers

The most important distinction is between prescription medicine and OTC medicine.

However, “available without a prescription” does not mean “safe for everyone.”

OTC medicines can still cause:

Allergic reactions
Drowsiness
Stomach irritation
Drug interactions
Accidental overdoses
Problems during pregnancy or breastfeeding
Incorrect dosing in children

How to Fill a Prescription in Korea

Step 1: Visit a Clinic or Hospital

If the doctor decides that prescription medicine is appropriate, the clinic will normally issue a prescription.

Paper prescriptions remain common, although the administrative process may vary between medical institutions.

Step 2: Check the Prescription Before Leaving

Confirm that the prescription shows the correct:

Patient name
Date of issue
Treatment period
Prescription usage period
Clinic information

The permitted usage period should be printed on the document. Do not assume that an old prescription can be used weeks or months later.

Step 3: Take the Prescription to a Pharmacy

You can normally take the prescription to a community pharmacy that is able to stock and dispense the medicine.

The pharmacy located next to the clinic is often the easiest option because it is likely to carry medicines frequently prescribed by that clinic. However, you are not generally required to use the closest pharmacy.

A different pharmacy may also fill the prescription if it:

Has the prescribed medicine
Can verify and process the prescription
Is able to complete any necessary safety checks

Step 4: Tell the Pharmacist About Important Medical Information

Before the medicine is dispensed, tell the pharmacist about:

Drug allergies
Pregnancy
Breastfeeding
Chronic health conditions
Medicine prescribed by another clinic
OTC medicines you are already taking
Vitamins, herbal products, or supplements
Previous serious side effects

Do not assume that all of this information is automatically visible to the pharmacist.

Step 5: The Pharmacist Reviews and Dispenses the Medicine

The pharmacist enters or reviews the prescription, checks the medicine, prepares the required quantity, and explains how to take it.

Korea uses a national Drug Utilization Review, or DUR, system. Doctors and pharmacists use the system during prescribing and dispensing to receive safety information about issues such as duplicate ingredients, age-related restrictions, pregnancy-related restrictions, incompatible combinations, and certain suspended medicines.

DUR is an important safety system, but it does not replace a direct conversation with the doctor or pharmacist. You should still disclose your medicines, allergies, and medical conditions.

Step 6: Confirm the Dosage Instructions

Before leaving the pharmacy, make sure you understand:

What each medicine is for
How many times a day to take it
How much to take each time
Whether to take it before or after food
Whether it may cause drowsiness
Whether you should avoid alcohol
Whether it must be refrigerated
How many days you should use it
What to do if you miss a dose

Do not begin taking the medicine until the basic schedule is clear.

Why Korean Prescription Medicine May Come in Small Pouches

Many Korean pharmacies package oral prescription medicines by dose.

For example, all tablets intended to be taken after breakfast may be placed together in one small pouch. Another pouch may contain the evening dose.

A pouch may show information such as:

Patient name
Date
Morning, afternoon, or evening
Before or after meals
Pharmacy name
Number of doses

This packaging can be convenient, but it may make it difficult to identify each tablet later.

Keep the following until the treatment is finished:

The original prescription
The pharmacy instruction sheet
The medicine bag
A photo of any printed dosage information

Can You Reuse a Korean Prescription?

Do not treat a Korean prescription as an automatic refill authorization.

A prescription is issued for:

A specific patient
A specific medical condition
Specific medicines and strengths
A limited quantity
A defined treatment period

Follow the usage period printed on the prescription.

After the prescribed quantity has been dispensed, you will generally need another medical consultation and a new prescription to obtain more prescription-only medicine. The doctor may prescribe a longer supply for some stable chronic conditions, but this depends on the medicine and clinical judgment.

Can You Use a Prescription Issued in Another Country?

A foreign prescription can be useful as supporting medical information, but you should not assume that a Korean pharmacy will treat it as a domestic prescription that can be dispensed immediately.

For prescription-only medicine, you may need to:

Visit a Korean clinic.
Show the doctor your foreign prescription or medical records.
Explain the active ingredient, strength, and usual dosage.
Receive a Korean prescription when medically appropriate.
Take the Korean prescription to a pharmacy.

Bring as much information as possible:

Original prescription
Doctor’s letter
Diagnosis or reason for treatment
Active ingredient
Strength, such as 5 mg or 500 mg
Dosage form
Normal daily dose
Photograph of the packaging
Recent medical records

Plan ahead if you take medicine for a long-term condition. Do not wait until your overseas supply is completely finished.

Additional restrictions may apply to narcotics, psychotropic medicines, sedatives, strong pain medicines, stimulants, and other controlled products.

How to Buy OTC Medicine at a Korean Pharmacy

You do not need to know the name of a Korean medicine before entering the pharmacy.

You can describe your symptoms and ask the pharmacist whether an OTC option may be appropriate.

The pharmacist may ask:

When did the symptoms begin?
Do you have a fever?
How severe are the symptoms?
How old is the patient?
How much does the child weigh?
Are you pregnant or breastfeeding?
Do you have any allergies?
Are you taking other medicines?
Do you have high blood pressure, diabetes, asthma, or another condition?
Have you already taken a painkiller or cold medicine today?

Korean law permits pharmacists to provide medicine information and help customers select OTC medicine without making a diagnostic judgment.

The pharmacist may recommend an OTC product, or advise you to visit a doctor when your symptoms require examination.

Common Reasons to Visit a Pharmacy Without a Prescription

Foreign residents commonly ask pharmacists about mild symptoms such as:

Headache
Mild fever
Runny nose
Sore throat
Cough
Indigestion
Heartburn
Diarrhea
Constipation
Motion sickness
Mild allergy symptoms
Minor muscle pain
Insect bites
Small cuts
Mild skin irritation

The symptom alone does not determine which medicine is suitable.

For example, a cold medicine may be unsuitable for someone who:

Has high blood pressure
Is pregnant
Is taking another product with the same pain-relief ingredient
Must drive or operate machinery
Has a particular allergy
Is below the approved age for the product

The Engineer Dad Rule: Compare Data, Not Package Design

A familiar brand name from your home country may not be sold in Korea.

Even when Korea has a medicine with the same medical purpose, it may have:

A different brand name
A different manufacturer
A different strength
A different combination of ingredients
A different dosage form
Different instructions

The reliable comparison is not:

“Does the package look similar?”

The reliable comparison is:

Active ingredient + strength + dosage form

For example:

Active ingredient: acetaminophen
Strength: 500 mg
Dosage form: tablet

This information is much more useful than showing the pharmacist only a foreign brand name.

How to Search for Korean Medicine Information

The Ministry of Food and Drug Safety operates Drug Safety Korea, also known in Korean as Nedrug or 의약품안전나라.

The database allows users to search for information including:

Product name
Active ingredient
Manufacturer
Prescription or OTC classification
Approved uses
Dosage instructions
Precautions
Product status

The official search system includes separate filters for prescription and OTC products and fields for indications, dosage, and precautions.

The website is primarily designed for Korean-language use. A browser translation tool may help, but medicine information should still be confirmed with a doctor or pharmacist.

Do Not Identify Medicine by Color or Shape Alone

Avoid requesting medicine by saying:

“I need the small white pill I took last time.”

Many unrelated medicines can have similar:

Colors
Shapes
Sizes
Coatings
Score lines

Instead, provide at least one reliable identifier:

Product package
Prescription
Pharmacy instruction sheet
Active ingredient
Strength
Manufacturer
Printed tablet code
Clear photo of both sides of the tablet
Previous pharmacy receipt or medicine bag

Appearance may help narrow a search, but it should not be the only basis for taking an unidentified medicine.

Can You Buy Medicine at a Convenience Store?

Yes, but the selection is very limited.

Registered retailers may sell 13 officially designated safe and readily available medicine products in categories such as:

Fever and pain relief
Cold medicine
Digestive medicine
Medicated pain-relief patches

The Ministry of Health and Welfare’s current policy page states that registered sellers must meet requirements such as operating a 24-hour store, completing required training, and using a barcode system that can block the sale of recalled or unsafe products. The rules also include package-sale limits and prohibit sales to children under the age of 12.

A convenience store is not a substitute for a pharmacy.

At a convenience store:

No pharmacist is present
The product selection is limited
You will not receive individualized medication counseling
Staff cannot assess drug interactions
The product you need may not be included in the approved list

Visit a pharmacy when you are unsure which product is appropriate.

Are All Convenience Stores Allowed to Sell Medicine?

No.

The store must be registered to sell safe and readily available medicine and must satisfy the applicable requirements.

Even at a registered convenience store, a particular product may be:

Out of stock
Temporarily unavailable
Removed from sale
Not included in that store’s inventory

Look for a designated medicine display or ask:

안전상비의약품 있나요?
Anjeon sangbi uiyagpum innayo?
“Do you have convenience-store medicine?”

Typical Pharmacy Opening Hours

Pharmacies are independently operated, so there is no single national schedule.

A neighborhood pharmacy may operate during the daytime and early evening. Pharmacies close to hospitals may open earlier or remain open later.

A pharmacy may be closed:

On Sundays
On public holidays
During a lunch break
Earlier on Saturdays
When the nearby clinic is closed
On designated weekly closing days

Operating hours shown on map applications may be outdated.

Always verify the hours when:

It is late at night
It is Sunday
It is a national holiday
You need medicine for a baby
You need an uncommon prescription product
You must travel a long distance

How to Find an After-Hours Pharmacy in Korea

Option 1: Use E-Gen

E-Gen is Korea’s official emergency medical information portal.

It provides location-based information about:

Emergency rooms
Hospitals
Clinics
Pharmacies
Institutions operating on holidays

The Korea Disease Control and Prevention Agency’s National Health Information Portal directs users to E-Gen for official emergency medical information.

Search results should still be confirmed by phone because operating information may change.

Option 2: Use Pharm114

Pharm114, commonly called the Holiday Keeper Pharmacy service, allows users to search for pharmacies operating during weekends, holidays, and other special hours.

The service is operated by the Korean Pharmaceutical Association.

The website is mainly in Korean, but browser translation can make it easier to use.

Useful search information includes:

City or province
District
Neighborhood
Date
Approximate time

Option 3: Search Your Local Government Website

Local governments may publish separate lists of:

Public late-night pharmacies
Holiday pharmacies
Pharmacies open throughout the year
Pharmacies offering foreign-language support

Availability and operating hours vary by city and district.

Do not assume that a public late-night pharmacy operates all night. Many programs use a fixed evening schedule, and the exact hours differ by region and pharmacy.

Option 4: Call Before You Leave

Call the pharmacy before traveling, especially when:

It is after normal business hours
It is a holiday
You need a specific prescription drug
You need a particular strength or dosage form
The patient is a baby or young child
The pharmacy is far away

A pharmacy may be open but may not stock the medicine you need.

What Is a Public Late-Night Pharmacy?

A public late-night pharmacy is a designated pharmacy that operates during vulnerable late-night hours with support or recognition from the government or local authorities.

Its purpose is to improve access to:

Basic medicine
Pharmacist counseling
Prescription dispensing
Medication safety information

“Public late-night” does not necessarily mean “24-hour.”

Check the exact closing time for the specific pharmacy on the date you plan to visit.

How Much Does Medicine Cost?

Prescription Medicine

The amount paid at the pharmacy may depend on:

National Health Insurance eligibility
Whether the medicine is covered
The number of treatment days
The prescribed quantity
The medicine selected
Dispensing-related charges
Night, weekend, or holiday surcharges when applicable

The pharmacist calculates the amount after processing the prescription.

OTC Medicine

OTC medicine is normally purchased directly by the customer.

Prices may vary depending on:

Brand
Manufacturer
Active ingredients
Package size
Pharmacy
Dosage form

You can ask:

가격이 얼마인가요?
Gagyeogi eolmaingayo?
“How much is it?”

You can also ask whether a less expensive product with the same active ingredient is available:

같은 성분으로 더 저렴한 제품이 있나요?
Gateun seongbuneuro deo jeoryeomhan jepumi innayo?

Important Medication Safety Rules

1. Check for Duplicate Active Ingredients

Cold, headache, fever, and pain medicines often contain combinations of several ingredients.

Two products with different brand names may contain the same:

Pain reliever
Fever reducer
Antihistamine
Cough suppressant
Decongestant

Taking both can result in an accidental overdose.

Show the pharmacist all medicines you have already taken that day.

2. Mention Pregnancy and Breastfeeding

Do not assume an OTC product is automatically safe during pregnancy or breastfeeding.

Tell the pharmacist before purchasing:

Tablets
Syrups
Creams
Patches
Herbal medicines
Vitamins
Supplements

3. Use the Child’s Current Weight

For children, the pharmacist may need:

Exact age
Current weight
Symptoms
Temperature
Allergies
Current medicine
Time of the previous dose
Amount of the previous dose

Do not estimate a child’s dosage using an adult product.

4. Do Not Share Prescription Medicine

A prescription is issued for a particular patient based on that person’s:

Age
Condition
Medical history
Allergies
Current medicines
Required dose

Do not share leftover:

Antibiotics
Sleeping medicine
Pain medicine
Steroids
Psychiatric medicine
Other prescription drugs

5. Do Not Change the Dosage by Yourself

Contact the doctor or pharmacist if:

You miss a dose
You vomit after taking the medicine
You accidentally take an extra dose
You develop a rash
Your symptoms worsen
You experience severe dizziness
You want to stop the medicine early

6. Keep Medicine in Its Original Packaging

Do not transfer medicine into an unlabeled container unless necessary.

Keep the:

Product name
Active ingredient
Expiration date
Storage instructions
Dosage directions
Pharmacy information

This information is important if you experience a side effect or need emergency treatment.

When You Should Visit a Doctor Instead of Only a Pharmacy

A pharmacy is helpful for mild and familiar symptoms, but it does not replace medical evaluation.

Visit a clinic or seek urgent medical help when:

Symptoms are severe
Symptoms are rapidly worsening
You have difficulty breathing
You have chest pain
You faint or become confused
You have a serious allergic reaction
A high fever continues
A baby or medically vulnerable person is ill
You may need antibiotics
Symptoms repeatedly return
You suspect a drug interaction
You are unsure what medicine was taken
You may have taken too much medicine

For a serious or potentially life-threatening emergency in Korea, call 119. Korea’s emergency medical system uses 119 to connect patients with emergency assistance and ambulance services.

Practical Pharmacy Checklist for Foreign Residents

Before visiting the pharmacy, prepare:

A photo of the medicine package
Active ingredient
Strength
Dosage form
List of current medicines
Allergy information
Pregnancy or breastfeeding information
Child’s age and weight
Prescription, when required
Translation application
Pharmacy phone number
Confirmed opening hours

Before leaving the pharmacy, confirm:

What is this medicine for?
What is the active ingredient?
How much should I take?
How many times a day?
Before or after meals?
Can it cause drowsiness?
Can I take it with my other medicine?
How should I store it?
How many days should I use it?
When should I visit a doctor?

Frequently Asked Questions

Can foreigners buy medicine at a Korean pharmacy?

Yes.

Foreign visitors and residents can purchase OTC medicine from Korean pharmacies. Prescription medicine generally requires an appropriate prescription regardless of nationality.

Do I need a Korean residence card?

A residence card is not usually necessary for a simple OTC purchase.

For medical consultations and insured prescription treatment, you may need identification and insurance-related information. Carry your passport or residence card when visiting a clinic or filling a prescription.

Can a Korean pharmacist speak English?

Some pharmacists speak English, particularly near:

International hospitals
Universities
Tourist areas
Large city centers
Neighborhoods with many foreign residents

English service is not guaranteed.

Use a translation application and prepare written information about symptoms, allergies, and current medicines.

Can a pharmacist prescribe antibiotics?

Antibiotics are generally prescription medicines in Korea.

You will normally need a medical examination and a prescription before a pharmacy can dispense them.

Can I buy cold medicine without a prescription?

Some cold medicines are OTC products and can be purchased directly from a pharmacy.

Other products or ingredients may require a prescription. Tell the pharmacist your symptoms and any medicine you have already taken.

Can I buy birth control pills without a prescription?

The classification depends on the exact product.

Some oral contraceptive products may be available without a prescription, while other hormonal products, including emergency contraception, may require a doctor’s prescription.

Ask about the specific product or active ingredient rather than assuming all contraceptives follow the same rule.

Can I buy sleeping pills without a prescription?

Many medicines specifically used to treat insomnia require a prescription, and some are controlled more strictly.

A pharmacist may carry certain OTC products for temporary sleep-related concerns, but these are not equivalent to prescription sleeping medicine.

Ask about:

Active ingredients
Drowsiness
Interactions
Driving restrictions
Recommended duration of use

Are Korean medicines weaker than foreign medicines?

Not necessarily.

Medicine strength should be compared using:

Active ingredient
Milligrams or concentration
Dosage form
Recommended dose

The country, brand name, package size, or number of tablets does not determine whether a medicine is stronger.

Will the pharmacist recognize my foreign brand name?

Possibly, but do not depend on the brand name alone.

Bring:

Active ingredient
Strength
Dosage form
Manufacturer
Photo of the ingredient label

Can I take my prescription to any pharmacy?

A community pharmacy may generally fill the prescription if it has the required medicine and can properly process the document.

Pharmacies near the issuing clinic are often more likely to stock the medicines commonly prescribed there.

What happens if the pharmacy does not have my medicine?

The pharmacist may:

Check whether it can be ordered
Direct you to another pharmacy
Contact the clinic for clarification
Discuss an approved equivalent when legally and clinically appropriate

Confirm the active ingredient, strength, and dosage before accepting an unfamiliar product.

Can the pharmacy replace the prescribed brand?

In some situations, a pharmacist may be able to dispense an approved product containing an equivalent ingredient, subject to Korean dispensing rules and any necessary communication with the prescribing provider.

Do not judge equivalence by package appearance. Confirm:

Active ingredient
Strength
Dosage form
Instructions

Are pharmacies open on Sundays?

Some are, but many are closed.

Use E-Gen, Pharm114, or your local government’s official pharmacy list, and call before visiting.

Are there 24-hour pharmacies in Korea?

True 24-hour pharmacies are not common throughout the country.

A pharmacy described as a late-night or public late-night pharmacy may still close at a fixed time.

Can I buy all OTC medicines at a convenience store?

No.

Convenience stores may sell only the officially designated safe and readily available medicine products. Visit a pharmacy for a wider selection and pharmacist advice.

Can I buy medicine online in Korea?

Do not assume that a website, marketplace seller, or social-media account is legally permitted to sell medicine.

Korean pharmaceutical sales are regulated, and products advertised online may be unauthorized, counterfeit, improperly stored, or illegally distributed.

Use licensed pharmacies and official medical channels.

Can I return medicine after purchasing it?

Returns may be restricted because medicine safety and storage conditions cannot always be verified after a product leaves the pharmacy.

Check the:

Product name
Quantity
Dosage form
Price

before completing the purchase. If the pharmacy made an error, contact it immediately without opening or using the medicine.

Can the pharmacist explain the medicine in English?

English explanations may be available, but they are not guaranteed.

Ask for:

Written dosage instructions
Ingredient name
Photos of the package
A simple morning-afternoon-evening schedule

Do not take the medicine until you understand the dosage.

Final Takeaway

The Korean pharmacy system is easier to understand when you separate it into three categories:

Prescription medicine requires an appropriate prescription in most situations.
OTC medicine can be purchased directly from a pharmacy with pharmacist guidance.
Convenience-store medicine is limited to a small officially designated list.

The most reliable way to compare medicine is to use:

Active ingredient + strength + dosage form

Do not rely only on brand names, package colors, or tablet appearance.

When you are unsure, show the pharmacist your medicine list, explain your allergies and medical conditions, and confirm the instructions before leaving.
