Hypertension in South Korea: Medications, Healthcare and Emergency Protocols
South Korea's hot, humid summers and strict MFDS medication rules create specific planning needs for hypertension travellers.
What changes when you travel to South Korea with hypertension
South Korea's summers (June to August) bring high temperatures and intense humidity under the influence of the North Pacific high-pressure system, both of which can affect blood pressure regulation and medication tolerability. A meta-analysis of Korean studies found that cardiovascular deaths increased by 6% for every 1ยฐC rise in summer temperature, making seasonal timing a real planning variable.[1]
This guide covers what you need before you fly: medication import rules under the Ministry of Food and Drug Safety (MFDS)[8], local brand names for common antihypertensives, how to access a cardiologist in Seoul or other cities, and what to say to Korean clinicians in an emergency. Storing your International Patient Summary (IPS) on Nomedic means your diagnosis, medications, and allergies are readable by any clinician, even without a shared language.

Key risks
Key risks for hypertension travellers in South Korea
Summer heat and humidity
Seoul recorded 39.6ยฐC on 1 August 2018, the highest temperature in 111 years, with humidity-driven heat indices significantly higher. Heat causes vasodilation, fluid loss, and can sharply amplify the effects of antihypertensives; see the In Country tab for day-to-day management strategies.
Medication import quantity limits
The MFDS permits a maximum three-month supply of non-narcotic prescription medications[7] for personal use. Carry original prescriptions and a doctor's letter confirming your condition and all medications you are importing, or the Korean Customs Service at Incheon Airport may confiscate them[6].[2]
Foreign prescriptions not accepted at Korean pharmacies
Korean pharmacies require a prescription issued by a Korean doctor before dispensing any prescription medication. If you run out of a medication, you must visit a local clinic first โ bring your Nomedic IPS and your original prescription to speed up the consultation.[3]
Amlodipine and simvastatin interaction
If you take both amlodipine and simvastatin, the FDA recommends not exceeding 20 mg daily of simvastatin due to the risk of myopathy. This interaction does not change in South Korea, but if a Korean clinician prescribes or adjusts a statin, flag this combination explicitly using your IPS.
High-sodium diet in Korean cuisine
Korean cuisine is characteristically high in sodium, largely driven by fermented condiments[9], soups, and stews such as kimchi jjigae and doenjang guk. Requesting less sauce (์์ค ์ ๊ฒ, sosseu jeogge) or choosing grilled dishes over broth-heavy options can help reduce daily sodium intake during the trip.
Preparation checklist
- Book a pre-travel cardiology review โ Confirm your blood pressure is stable and get a letter stating your diagnosis, all medications, and doses on headed paper.
- Obtain a three-month supply of all antihypertensives โ The MFDS personal-use limit is three months; do not rely on refilling in Korea without a local prescription.
- Get prescriptions with INN names โ Ensure each prescription lists both the brand name and International Nonproprietary Name so Korean pharmacists can find an equivalent.
- Download your Nomedic IPS โ Your IPS stores your diagnosis, medications, allergies, and emergency contacts offline with a QR code any clinician can scan.
- Check your travel insurance covers hypertension โ Confirm hypertension is explicitly listed as a covered pre-existing condition on your policy schedule.
- Identify a cardiologist near your destination โ Use Nomedic's provider search to locate a cardiology department (์ํ๊ธฐ๋ด๊ณผ) before departure and save the address offline.
- Pack medications in hand luggage only โ Do not check antihypertensives in hold luggage; delays or lost bags can leave you without medication for days.
- Pack a printed doctor's letter and original prescriptions โ Korean Customs at Incheon Airport may require these if the quantity of medication appears to exceed personal use.
- Save South Korea emergency numbers offline โ Ambulance and fire: 119. Police: 112. Save both in Nomedic before you travel.
- Check summer travel dates and plan heat mitigation โ If travelling June through August, plan outdoor activities before 10:00 and after 17:00 to avoid peak heat.
Documents to carry
Documents to carry when travelling to South Korea with hypertension
Korean clinicians cannot access foreign medical records, so carrying structured documentation โ ideally through the Nomedic app โ is the fastest way to receive safe, accurate care.
Your International Patient Summary (IPS)
The IPS is a standardised clinical document that contains your diagnosis, current medications (with INNs), allergies, and relevant history in a format readable by any clinician worldwide. In South Korea, where most clinicians read English-language medical documents but may not speak it fluently, a machine-readable IPS removes ambiguity in an emergency.
Nomedic generates your IPS to the HL7 FHIR standard and stores it offline with a QR code. Tap Share in the app and any clinician can scan it instantly โ no app download required on their end.

Medications advice
Bringing your hypertension medications to South Korea
Common antihypertensives such as amlodipine, losartan, and lisinopril do not contain narcotics or amphetamines, so they fall under the general personal-use import rule: up to a three-month supply is permitted, provided you carry the original prescriptions and a doctor's letter specifying your condition and all medications.[2] The Korean Customs Service at Incheon Airport has final authority over what is admitted, so documentation must be complete and in the original packaging.
Do not post your medication to South Korea.
Mailing prescription medications into South Korea is subject to import approval procedures and may result in confiscation. Always carry antihypertensives in your hand luggage on the flight.
Hypertension medications: brand names, INNs, and South Korea availability
Most common antihypertensives are available in South Korea, but under different brand names; the table below lists South Korean equivalents so you can communicate clearly with a local pharmacist or clinician.
Store below 30ยฐC; avoid prolonged exposure to humidity during summer travel.
Diuretic effect increases fluid loss in hot weather; monitor hydration carefully in summer.
Amlodipine and simvastatin: do not exceed 20 mg simvastatin daily
Co-administration of amlodipine with simvastatin doses above 20 mg daily increases the risk of myopathy, including rhabdomyolysis. If a Korean clinician prescribes a statin or adjusts your existing statin dose, show them your full medication list on your Nomedic IPS and specifically flag this combination. This is a known interaction listed in the amlodipine prescribing information.
Travelling with injectable therapies
If your hypertension management includes any injectable medication, these steps apply regardless of your destination within South Korea.

Nomedic stores your medication name, INN, dosage, and frequency โ readable by any clinician worldwide.
At your destination
Healthcare and prescriptions in South Korea
South Korea's national health system is the National Health Insurance (NHI) service, but it does not extend to foreign visitors without a Korean NHI card. All visitors pay the full unsubsidised cost of treatment and must settle accounts at the time of service.[3] A private clinic consultation in Seoul typically costs โฉ30,000โโฉ80,000 (~$22โ$59 / ~โฌ20โโฌ54), with additional fees for any diagnostic tests. Foreign prescriptions are not accepted at Korean pharmacies; if you need a local prescription, visit a clinic first, then take the issued prescription to the nearest pharmacy (์ฝ๊ตญ, yakguk).
Most common antihypertensives are available at Korean retail pharmacies under local brand names, but the pharmacist will require a Korean-issued prescription before dispensing. Psychotropic medications may not be stocked at retail pharmacies, but standard cardiovascular medications such as amlodipine, losartan, bisoprolol, and valsartan are widely available.
Antihypertensives are dispensed via retail pharmacies
Standard antihypertensives are stocked at retail pharmacies (์ฝ๊ตญ) throughout South Korea. In an emergency, go to the nearest clinic or hospital outpatient department, present your Nomedic IPS and original prescription, and obtain a local prescription to take to any pharmacy. Major hospitals in Seoul such as Seoul National University Hospital and Samsung Medical Centre have international patient centres with English-speaking staff.
Finding a hypertension specialist
Cardiologists in South Korea practice within internal medicine, specifically in departments called ์ํ๊ธฐ๋ด๊ณผ (sunhwangi naekwa, cardiovascular internal medicine), found in all major hospitals and university centres. Most large hospitals in Seoul, Busan, and Daegu have international patient centres that provide English-speaking appointment coordination; walk-in access is generally available at clinic level, though waiting times at public hospitals can be 1โ3 hours. Identify the nearest cardiology department before you travel and save the address and phone number offline in Nomedic.
Search for providers near your destination
Use Nomedic's provider search to find hypertension specialists in South Korea. Save the address and phone number offline before you travel.
If you miss a dose or run out of medication in South Korea
A single missed dose of most antihypertensives does not produce an immediate crisis, but do not assume this applies to your specific regimen without confirming with your prescribing clinician. Beta-blockers in particular should not be stopped abruptly; check your product leaflet for the specific guidance for your medication.
Managing heat, humidity and sodium day to day in South Korea
South Korea's summer (JuneโAugust) is characterised by high temperatures and very high humidity under the North Pacific high-pressure system, with Seoul reaching up to 39.6ยฐC. A meta-analysis of Korean data found that cardiovascular deaths rose 6% for every 1ยฐC increase in summer temperature, making heat the primary environmental consideration for hypertension travellers.[5]
Plan outdoor activity before 10 am and after 5 pm to avoid peak heat. South Korea operates a network of public cooling shelters (๋ฌด๋์์ผํฐ, mudeoui swimteo) including libraries, community centres, and subway stations โ these are free to use and air-conditioned. Korean cuisine is high in sodium; request less sauce (์์ค ์ ๊ฒ ์ฃผ์ธ์, sosseu jeogge juseyo) or choose grilled proteins over broth-heavy soups to manage daily sodium load. Stay well hydrated with water or low-sugar drinks and avoid excessive alcohol, which amplifies vasodilation. If you take a diuretic, monitor for signs of dehydration more actively in hot weather.
Dizziness from heat is not always a hypertensive crisis
Vasodilation, sweating, and mild drops in blood pressure are expected responses to South Korea's summer heat and may feel like warning signs. Rest in a cool, shaded area, rehydrate, and allow 15โ20 minutes before re-evaluating. If symptoms include a severe headache, visual changes, chest pain, or confusion that persist after cooling down, follow the guidance in the Emergency tab.
Korean phrases for clinicians
Show your Nomedic IPS first โ it removes the need to explain your diagnosis verbally. If verbal communication is needed:
“์ ๋ ๊ณ ํ์์ด ์์ต๋๋ค.”
I have hypertension.
“ํ์์ด ์ํํ๊ฒ ๋์์ก์ต๋๋ค.”
My blood pressure has risen dangerously.
“์ฌ์ฅ ์ ๋ฌธ์๊ฐ ํ์ํฉ๋๋ค.”
I need a cardiologist.
“์ ๋ ํ์์ฝ์ ๋ณต์ฉํ๊ณ ์์ต๋๋ค.”
I take blood pressure medication.
“๊ฐ์ฅ ๊ฐ๊น์ด ์ฌ์ฅ๋ด๊ณผ๋ ์ด๋์ ๋๊น?”
Where is the nearest cardiology department?
“ํ์์ฝ์ ๊ธด๊ธ์ผ๋ก ์ฒ๋ฐฉ๋ฐ๊ณ ์ถ์ต๋๋ค.”
I need an emergency supply of blood pressure medication.
Insurance considerations
What to know about travel insurance
Many general travel policies exclude cardiovascular conditions unless declared and specifically underwritten. Emergency hospitalisation for a hypertensive crisis in South Korea at a private international hospital can run to โฉ500,000โโฉ3,000,000 (~$370โ$2,200 / ~โฌ340โโฌ2,020) per day before procedures, making adequate cover essential.
What to look for in a policy
Not just 'pre-existing conditions covered'. Your condition should be named on the policy schedule.
Covers repatriation to your home country if local care is insufficient or specialist follow-up is required.
Covers emergency replacement if your antihypertensives are lost, damaged, or delayed in transit.
So someone can communicate with Korean clinicians on your behalf, particularly in secondary hospitals where English may be limited.
What to declare at application
Declare thoroughly. Incomplete disclosure can invalidate your entire policy, not just the hypertension-related claim.
State whether your hypertension is primary or secondary, and whether it is currently controlled or uncontrolled.
Use the INN alongside the brand name. For example: amlodipine (Norvasc), losartan (Cozaar).
Insurers often ask for the most recent reading and the date of last GP review.
Declare any comorbidities including diabetes, chronic kidney disease, dyslipidaemia, or coronary artery disease.
Your policy number and emergency assistance line, saved alongside your IPS and accessible offline.
South Korea has no reciprocal healthcare agreement with EU or EEA member states, so an EHIC or GHIC card provides no benefit here. All foreign visitors pay the full unsubsidised cost of treatment and must settle bills directly with the provider. Comprehensive travel insurance with hypertension cover is therefore essential regardless of your nationality.
Emergency protocol
Get to the nearest emergency department immediately
A severe headache, blurred vision, chest pain, or confusion alongside very high blood pressure readings requires immediate emergency care. Contact your travel insurer's assistance line before or alongside calling 119 โ they can arrange direct billing with Korean hospitals and provide an interpreter.
When you arrive โ follow in order
Full clinical picture in seconds, no verbal explanation needed.
Hand your phone to the triage nurse:
์ ๋ ๊ณ ํ์ ์๊ธฐ ์ํ์ ๋๋ค. ์ฆ์ ์ง๋ฃ๊ฐ ํ์ํฉ๋๋ค.
I am having a hypertensive crisis. I need immediate care.
Your Nomedic IPS includes all current antihypertensives โ clinicians need this before giving any emergency medication.
If you take both, flag it explicitly before any statin is adjusted in the emergency setting.
Calls and location
Call 119 for ambulance and fire services. Call 112 for police. For English-speaking operator assistance with Korean emergency services, call +82-2-3210-0404 (South Korea International Emergency Call Centre) and ask for an English speaker. Give your location as precisely as possible, including the nearest subway station or landmark.
In hospital
Several antihypertensives interact with anaesthetic agents and can cause significant intraoperative hypotension. Tell the attending clinician the names, INNs, and doses of all your blood pressure medications before any procedure, and share your Nomedic IPS immediately on arrival.
After any emergency
Before you leave the hospital if possible.
Required for insurer reimbursement and continuity of care with your home clinician.
Open Nomedic and tap Share to generate a QR code any clinician can scan.
Frequently asked questions
Can I bring my hypertension medication into South Korea?
Yes. Standard antihypertensives (amlodipine, losartan, lisinopril, bisoprolol, valsartan) do not contain narcotics or amphetamines, so the general rule applies: up to a three-month personal-use supply is permitted with original prescriptions and a doctor's letter.[3]
Do not post medication to South Korea
Mailing prescription drugs into Korea requires import approval and risks confiscation. Always carry in hand luggage.
Are hypertension medications available in South Korea pharmacies?
Yes, the major antihypertensive classes are stocked at Korean retail pharmacies (์ฝ๊ตญ, yakguk), but you must first visit a local clinic to obtain a Korean-issued prescription, as foreign prescriptions are not accepted. Expect a clinic consultation fee of โฉ30,000โโฉ80,000 (~$22โ$59 / ~โฌ20โโฌ54) and a medication cost of approximately โฉ20,000 (~$15 / ~โฌ14) for a one-week supply of a common generic.

How can I communicate my hypertension diagnosis in an emergency in South Korea?
Show your Nomedic IPS first. If verbal communication is needed:
“์ ๋ ๊ณ ํ์์ด ์์ต๋๋ค.”
I have hypertension.
“์ ๋ ํ์์ฝ์ ๋ณต์ฉํ๊ณ ์์ต๋๋ค.”
I take blood pressure medication.
How does South Korea's summer heat affect blood pressure management?
South Korea's summer (JuneโAugust) brings high temperatures and humidity that cause vasodilation and increased fluid loss, both of which can amplify the effects of antihypertensives and cause dizziness or hypotension. Diuretics in particular require more careful hydration monitoring in this climate.
Use public cooling shelters
South Korea operates free air-conditioned public cooling shelters (๋ฌด๋์์ผํฐ) in subway stations, libraries, and community centres โ a practical resource during heat waves. Plan outdoor activity before 10:00 and after 17:00.
Do I need special travel insurance to visit South Korea with hypertension?
Yes. South Korea has no reciprocal healthcare agreement with most countries, meaning all visitors pay the full unsubsidised cost of care. Standard travel policies often exclude pre-existing cardiovascular conditions, and emergency hospitalisation at a private Seoul hospital can reach โฉ500,000โโฉ3,000,000 (~$370โ$2,200 / ~โฌ340โโฌ2,020) per day before procedures.
Declare thoroughly
Subtype, current medication, last blood pressure reading, and all associated conditions. Incomplete disclosure invalidates the entire policy.
