You do not need to memorize a long list of medicine names before buying medicine at a pharmacy in Korea. Once you enter the pharmacy, first explain where you feel unwell and when the symptoms began, then add information about any medicines you are currently taking, drug allergies, pregnancy, or breastfeeding. This helps the pharmacist understand what needs to be checked next. It is also fine if you do not know the Korean name of a medicine. You can show the pharmacist the medicine bag, outer packaging, English ingredient name, or a photo. This article covers Korean pharmacy phrases that are particularly useful while traveling, including symptoms, how long they have lasted, how to use medicine, finding a pharmacy on a holiday, and the difference between 119 and 1330.
What should you say when buying medicine at a Korean pharmacy? Start with your symptoms, how long they have lasted, and your current medications
You do not need to know a product name before entering a Korean pharmacy. You can begin with 「약을 찾고 있는데요」 to say that you are looking for medicine, then explain your physical condition. If you do not have a specific product in mind and want the pharmacist to help assess your needs, you can also say 「약사님과 상담하고 싶어요」 directly.
The most useful information in a pharmacy conversation generally includes where you feel unwell, when the symptoms began, whether you are currently using other medicines, and whether you have allergies or need to disclose that you are pregnant or breastfeeding. Instead of preparing one long sentence, it is better to give these pieces of information separately.
- Example: 약을 찾고 있는데요.
Romanization: yak-eul-chat-go-it-neun-de-yo.
Translation: I’m looking for medicine.
「-는데요」leaves the sentence open while waiting for the other person to respond, making it a suitable way to begin a conversation after entering the pharmacy. You can then add your symptoms or what you need. - Example: 목이 아픈데, 약사님과 상담하고 싶어요.
Romanization: mok-i-a-peun-de-yak-sa-nim-gwa-sang-dam-ha-go-si-peo-yo.
Translation: My throat feels uncomfortable, and I would like to consult the pharmacist.
The sentence explains the discomfort first and leaves the next assessment to the pharmacist, so you do not have to name a particular medicine in advance. - Example: 이 약은 어떻게 복용하면 돼요?
Romanization: i-yak-eun-eo-tteo-ke-bok-yong-ha-myeon-dwae-yo?
Translation: How should I take this medicine?
「복용하다」is a more formal way to say “take medicine” and sounds natural when asking how to use an oral medicine at a pharmacy.
Common Korean pharmacy vocabulary: Symptoms, medicines, usage, and precautions
You do not need to memorize all the Korean used at pharmacies as medicine names. Being able to explain “headache, cough, and where it hurts,” along with words such as “take, apply, allergy, and side effect,” is already enough to handle many basic exchanges.
The vocabulary below is only for describing your physical condition and asking for information. It does not indicate what type of medicine should be used for a particular symptom.
| Korean | Romanization | English meaning | Common usage |
| 약국 | yak-guk | Pharmacy | 약국이 어디예요? |
| 약사 | yak-sa | Pharmacist | 「약사님」is commonly used when addressing a pharmacist |
| 증상 | jeung-sang | Symptom, discomfort | 증상이 있어요 |
| 두통 | du-tong | Headache | 두통이 있어요 |
| 기침 | gi-chim | Cough | 기침이 계속돼요 |
| 알레르기 | al-le-reu-gi | Allergy | 알레르기가 있어요 |
| 약물 알레르기 | yak-mul-al-le-reu-gi | Drug allergy | Important information to volunteer at a pharmacy |
| 복용하다 | bok-yong-ha-da | To take medicine | Used for oral medicine |
| 바르다 | ba-reu-da | To apply | Often used for ointments |
| 부작용 | bu-jak-yong | Side effect | 부작용이 있나요? |
| 주의사항 | ju-ui-sa-hang | Precautions | 주의사항이 있나요? |
| 처방전 | cheo-bang-jeon | Prescription | 처방전이 필요해요? |
Buying medicine at a Korean pharmacy ①｜Use 「아파요」 and 「불편해요」 to explain where you feel unwell
When a particular part of your body hurts, you can use 「noun＋이／가 아파요」. For example, 「머리가 아파요」means that your head hurts, while 「배가 아파요」means that your stomach hurts.
If the discomfort is difficult to describe clearly as pain, such as when your stomach feels strange or part of your body simply feels uncomfortable, you can also use 「불편해요」. This word has a broader range than 「아파요」and does not directly limit the symptom to pain.
- Example: 머리가 아파요.
Romanization: meo-ri-ga-a-pa-yo.
Translation: My head feels very uncomfortable／I have a headache.
This is the most basic way to identify the affected area. If you need to add when the symptom began, you can follow it with a time expression such as 「아침부터」or 「어제부터」. - Example: 어제부터 배가 아파요.
Romanization: eo-je-bu-teo-bae-ga-a-pa-yo.
Translation: My stomach has felt uncomfortable since yesterday.
「어제부터」adds when the symptom began, giving the pharmacist one more useful piece of information than simply saying 「배가 아파요」. - Example: 배가 좀 불편한데요.
Romanization: bae-ga-jom-bul-pyeon-han-de-yo.
Translation: My stomach feels a little uncomfortable.
When the condition is not clearly painful, 「불편하다」is more suitable than directly using 「아프다」. 「좀」also makes the description sound closer to everyday conversation.
Buying medicine at a Korean pharmacy ②｜Use 「부터」 and 「며칠째」 to say how long your symptoms have lasted
When a pharmacist asks about your condition, the time the symptoms began is also useful information. 「어제부터」means “since yesterday,” and 「오늘 아침부터」means “since this morning.” If the symptoms have continued for several days, you can use 「며칠째」.
「며칠째」does not simply mean “several days”; it indicates that something has continued up to the present, making it suitable for describing ongoing conditions such as a cough or throat discomfort.
- Example: 오늘 아침부터 목이 아파요.
Romanization: o-neul-a-chim-bu-teo-mok-i-a-pa-yo.
Translation: My throat has felt uncomfortable since this morning.
「부터」identifies the point when the symptom began and can be directly replaced with expressions such as 「어제부터」or 「이틀 전부터」. - Example: 기침이 며칠째 계속돼요.
Romanization: gi-chim-i-myeo-chil-jjae-gye-sok-dwae-yo.
Translation: My cough has continued for several days.
Combining 「며칠째」with 「계속돼요」clearly describes a condition that has continued for several days and has not yet stopped. - Example: 갑자기 머리가 아프기 시작했어요.
Romanization: gap-ja-gi-meo-ri-ga-a-peu-gi-si-jak-hae-sseo-yo.
Translation: My head suddenly started to hurt.
「갑자기」means “suddenly,” while 「-기 시작하다」indicates that a condition began. It is useful for explaining that the symptom did not build gradually.
Buying medicine at a Korean pharmacy ③｜Mention drug allergies, current medications, pregnancy, or breastfeeding first
Drug allergies, the use of other medicines, pregnancy, and breastfeeding are all pieces of information that should be volunteered before buying or using medicine. If you know the name of the medicine or ingredient, you can provide it directly. If you are unsure of the Korean name, showing the medicine bag, outer packaging, or a photo is usually clearer than guessing the name yourself.
「지금 복용 중인 약이 있어요」is slightly more formal than 「지금 먹고 있는 약이 있어요」, but both will be understood at a pharmacy. When you specifically need to mention a drug allergy, you can use 「약물 알레르기가 있어요」.
- Example: 약물 알레르기가 있어요.
Romanization: yak-mul-al-le-reu-gi-ga-i-sseo-yo.
Translation: I have a drug allergy.
If you know the medicine or ingredient that causes the allergy, it is best to add the name directly or give the pharmacist your existing records to check. - Example: 지금 복용 중인 약이 있어요.
Romanization: ji-geum-bok-yong-jung-in-yak-i-i-sseo-yo.
Translation: I am currently taking medicine.
「복용 중인 약」means medicine that you are currently taking. This sentence alone is still not enough to determine whether medicines can be combined, so you need to provide the actual medication information afterward. - Example: 임신 중이라서 약을 먹어도 되는지 먼저 확인하고 싶어요.
Romanization: im-sin-jung-i-ra-seo-yak-eul-meo-geo-do-doe-neun-ji-meon-jeo-hwak-in-ha-go-si-peo-yo.
Translation: I’m pregnant, so I would like to check first whether I can take this medicine.
The sentence does not independently decide whether the medicine can be used. Instead, it first makes the situation requiring special confirmation clear. If you are breastfeeding, you can begin by saying 「수유 중이에요」.
How do you ask about using medicine at a Korean pharmacy? A complete comparison of 「먹다」, 「복용하다」, 「사용하다」, and 「바르다」
After receiving a product, you do not always ask how to use it with 「어떻게 먹어요?」. For oral products, you can use 「먹다」or the more formal 「복용하다」. 「바르다」is commonly used for ointments, while 「사용하다」can describe how to use a product more generally.
At a pharmacy, clarifying the frequency, timing, and precautions is more useful than simply remembering a product name. The actual way to take or use the product should still follow the information provided by the pharmacist and the product label.
「먹다」vs「복용하다」｜Everyday “take medicine” vs formal “administer orally”
「먹다」originally means “to eat,” and it is also extremely common in everyday Korean for taking medicine. 「복용하다」means “to take medicine” in a more formal register and is common in pharmacies, medical explanations, and written medication information.
- Example: 이 약은 어떻게 먹어요?
Romanization: i-yak-eun-eo-tteo-ke-meo-geo-yo?
Translation: How do I take this medicine?
This is the most direct everyday question and is completely usable in a pharmacy conversation. - Example: 이 약은 어떻게 복용하면 돼요?
Romanization: i-yak-eun-eo-tteo-ke-bok-yong-ha-myeon-dwae-yo?
Translation: How should I take this medicine?
「복용하다」sounds more formal, but its meaning is close to the previous sentence. - Example: 하루에 몇 번 복용하면 돼요?
Romanization: ha-ru-e-myeot-beon-bok-yong-ha-myeon-dwae-yo?
Translation: How many times a day should I take it?
「하루에 몇 번」directly asks about the daily frequency, so you do not need to guess the abbreviations on the packaging.
「바르다」vs「사용하다」｜Applying ointment vs general use
You do not use 「먹다」for a topical ointment. The Korean verb 「바르다」means “to apply,” so when you see a product such as 「연고」, you can ask 「어떻게 발라요?」directly.
- Example: 이 연고는 어떻게 발라요?
Romanization: i-yeon-go-neun-eo-tteo-ke-bal-la-yo?
Translation: How do I apply this ointment?
The polite conversational form of 「바르다」is 「발라요」, which is suitable for asking directly about topical use. - Example: 하루에 몇 번 발라요?
Romanization: ha-ru-e-myeot-beon-bal-la-yo?
Translation: How many times a day should I apply it? - This also uses 「하루에 몇 번」to ask about frequency, but the verb changes to 「바르다」, which suits a topical product.
- Example: 사용할 때 주의할 점이 있나요?
Romanization: sa-yong-hal-ttae-ju-ui-hal-jeom-i-it-na-yo?
Translation: Is there anything I should be careful about when using it?
If you are not sure which precautions to ask about, this sentence lets you ask broadly, and you can then confirm the details based on the pharmacist’s explanation.
How do you ask for medicine at a Korean pharmacy? Differences among 「있어요?」, 「찾고 있는데요」, and 「상담하고 싶어요」
At a Korean pharmacy, you can simply ask whether something is available, say that you are looking for it, or directly state that you would like to consult the pharmacist. All three approaches are natural, but they begin the conversation from different points.
| Expression | Main meaning | Suitable situation | Focus of the conversation |
| 두통약 있어요? | Do you have headache medicine? | You already know what type of product you need | Check whether the product is available |
| 두통약을 찾고 있는데요. | I’m looking for headache medicine | You want the other person to help you find it | Leave room for the other person to respond |
| 두통이 있는데 상담하고 싶어요. | I have a headache and would like a consultation | You need to explain your condition first | Allow the pharmacist to ask further questions |
「약 있어요?」and「약을 찾고 있는데요」｜Asking directly vs opening a conversation
「있어요?」is the most direct question about whether something exists or is available. There is no problem using it when you already know the type of product you want. 「찾고 있는데요」carries the nuance of “I’m currently looking for…” and the final 「는데요」naturally waits for the other person’s response, making it more like an opening line.
- Example: 감기약 있어요?
Romanization: gam-gi-yak-i-sseo-yo?
Translation: Do you have cold medicine? This short, clear sentence directly checks whether a certain type of product is sold. - Example: 감기약을 찾고 있는데요.
Romanization: gam-gi-yak-eul-chat-go-it-neun-de-yo.
Translation: I’m looking for cold medicine.
「는데요」does not fully close the statement, so the pharmacist will naturally continue by asking about your symptoms or what type of product you need. - Example: 목이 아프고 기침이 있는데, 약사님과 상담하고 싶어요.
Romanization: mok-i-a-peu-go-gi-chim-i-it-neun-de-yak-sa-nim-gwa-sang-dam-ha-go-si-peo-yo.
Translation: My throat feels uncomfortable and I have a cough, so I would like to consult the pharmacist.
When there is more than one symptom, stating the symptoms first makes it easier to continue the conversation than deciding on a product name yourself.
How do you ask 「같이 먹어도 돼요?」? Provide information about the medicine you are currently taking first
「같이 먹어도 돼요?」means “Can I take them together?” and there is nothing wrong with the sentence itself. What is easy to overlook is the prerequisite information: if the pharmacist does not know exactly what the other medicine is, this sentence is still not enough for them to check.
A more complete approach is to say first that you are currently taking another medicine, then show the outer packaging, medicine bag, photo, or ingredient information.
- Example: 지금 복용 중인 약이 있는데요.
Romanization: ji-geum-bok-yong-jung-in-yak-i-it-neun-de-yo.
Translation: I am currently taking another medicine.
「있는데요」indicates that there is more information to add and also tells the pharmacist that your existing medication needs to be checked next. - Example: 이 사진을 보여 드려도 될까요?
Romanization: i-sa-jin-eul-bo-yeo-deu-ryeo-do-doel-kka-yo?
Translation: May I show you this photo?
「-아／어도 될까요」politely asks for permission. If you are unsure of the medicine’s name, you can directly show a photo of the product or medicine bag. - Example: 이 약과 같이 먹어도 되는지 확인해 주세요.
Romanization: i-yak-gwa-ga-chi-meo-geo-do-doe-neun-ji-hwak-in-hae-ju-se-yo.
Translation: Please check whether I can take it together with this medicine.
The sentence gives the pharmacist the actual medication information to check instead of asking only “Can I take them together?” without clearly identifying the other product.
What if Korean pharmacies are closed? Holiday pharmacies, late-night pharmacies, 119, and 1330 explained
While traveling in Korea, not every pharmacy is open at night or on holidays. 「휴일지킴이약국」can be used to search for open and late-night pharmacies. Actual opening information may still change at short notice, so it is safer to check again before leaving.
If you need travel information or language assistance, or do not know which service to contact next, you can use the Korea Tourism Organization’s 1330 service. If you already have a medical emergency or need an ambulance, call 119 directly and do not treat 1330 as an emergency number.
How do you find a holiday pharmacy in Korea? 「지금 문 연 약국」and late-night pharmacy searches
When you suddenly need to find a pharmacy that is still open, 「문을 열다」means to open or operate, and 「문 연 약국」means a pharmacy that is currently open.
- Example: 근처에 약국이 있나요?
Romanization: geun-cheo-e-yak-guk-i-it-na-yo?
Translation: Is there a pharmacy nearby?
This is the most direct way to ask when you do not know where a pharmacy is. - Example: 지금 문 연 약국이 어디예요?
Romanization: ji-geum-mun-yeon-yak-guk-i-eo-di-ye-yo?
Translation: Where is a pharmacy that is open now?
When looking for a pharmacy at night or on a holiday, this adds the condition that it must currently be open, unlike simply asking 「약국이 어디예요?」. - Example: 오늘 늦게까지 하는 약국이 있나요?
Romanization: o-neul-neut-ge-kka-ji-ha-neun-yak-guk-i-it-na-yo?
Translation: Is there a pharmacy that stays open late today?
「늦게까지 하다」means to stay open late and is suitable when asking hotel reception staff or a local service worker.
Korean emergency medical number 119 vs travel assistance 1330: Which should you call?
If your physical condition is already an emergency, you should not remain at the stage of deciding which pharmacy to find. Korea’s fire and emergency medical number is 119. The Korea Tourism Organization’s 1330 service provides travel consultation and multilingual support and can help with travel information and language communication.
- Example: 119에 전화해 주세요.
Romanization: il-il-gu-e-jeon-hwa-hae-ju-se-yo.
Translation: Please call 119.
In an emergency, you can directly ask someone nearby to call 119 without first organizing a long explanation in Korean. - Example: 응급실에 가야 할 것 같아요.
Romanization: eung-geup-sil-e-ga-ya-hal-geot-ga-ta-yo.
Translation: I think I need to go to the emergency room.
「응급실」means the emergency room. This sentence expresses that what you need may no longer be a regular pharmacy service. - Example: 통역 도움을 받을 수 있을까요?
Romanization: tong-yeok-do-um-eul-ba-deul-su-i-sseul-kka-yo?
Translation: Could I get interpreting assistance?
If language communication becomes difficult, you can ask directly whether translation or interpreting assistance is available instead of forcing yourself to explain complex information in Korean.
Practical Korean pharmacy conversations: Three situations travelers commonly encounter
You do not need to give all the information at once during a pharmacy conversation. It is closer to a real exchange to explain the main discomfort first, then add how long it has lasted, any allergies, or current medication after the pharmacist asks follow-up questions.
▌Situation ①｜Your stomach has felt uncomfortable since yesterday
A：어제부터 배가 불편한데, 약사님과 상담하고 싶어요.
eo-je-bu-teo-bae-ga-bul-pyeon-han-de-yak-sa-nim-gwa-sang-dam-ha-go-si-peo-yo.
My stomach has felt uncomfortable since yesterday, and I would like to consult the pharmacist.
B：지금 복용 중인 약이나 약물 알레르기가 있으세요?
ji-geum-bok-yong-jung-in-yak-i-na-yak-mul-al-le-reu-gi-ga-i-sseu-se-yo?
Are you currently taking any medicine, or do you have any drug allergies?
📌 Grammar Point: 「어제부터」first states when the symptoms began, while 「-는데」connects the condition to the request for a consultation. The pharmacist’s question checks both current medication and allergy information.
▌Situation ②｜Checking how to use an oral medicine after receiving it
A：이 약은 어떻게 복용하면 돼요?
i-yak-eun-eo-tteo-ke-bok-yong-ha-myeon-dwae-yo?
How should I take this medicine?
B：복용 방법은 여기 적혀 있어요. 주의사항도 같이 확인해 주세요.
bok-yong-bang-beop-eun-yeo-gi-jeok-hyeo-i-sseo-yo-ju-ui-sa-hang-do-ga-chi-hwak-in-hae-ju-se-yo.
The directions are written here. Please check the precautions as well.
📌 Grammar Point: 「어떻게 복용하면 돼요?」asks directly about how to use the medicine without guessing how many times a day it should be taken. The actual frequency and precautions should be confirmed according to the pharmacist’s instructions and the product label.
▌Situation ③｜Showing a photo first when you already take another medicine
A：지금 복용 중인 약이 있는데, 이 사진을 보여 드려도 될까요?
ji-geum-bok-yong-jung-in-yak-i-it-neun-de-i-sa-jin-eul-bo-yeo-deu-ryeo-do-doel-kka-yo?
I am currently taking another medicine. May I show you this photo?
B：네, 보여 주세요. 약물 알레르기가 있는지도 알려 주세요.
ne-bo-yeo-ju-se-yo-yak-mul-al-le-reu-gi-ga-it-neun-ji-do-al-lyeo-ju-se-yo.
Yes, please show me. Please also tell me whether you have any drug allergies.
📌 Grammar Point: 「-아／어도 될까요」is used to ask whether you may do something. 「-는지」turns “whether you have a drug allergy” into information that needs to be confirmed.
Cultural Notes:
- Korean pharmacy signs usually display the character 「약」directly, so a large 「약」sign seen during a trip will usually help you identify a pharmacy. Once inside, you do not need to force yourself to memorize a particular Korean brand name. It is more practical to explain your condition first and let the pharmacist ask follow-up questions.
- Medicine names are not necessarily identical across countries. Even if you have used a particular product before, it is not appropriate to look for a Korean version based only on the outer box color or the Chinese product name. A photo of the box, the English ingredient name, or the original medicine bag is easier to use for confirmation.
- 「어떻게 먹어요?」is not impolite and is also common at pharmacies. 「어떻게 복용하면 돼요?」simply uses a register closer to written medication instructions. Travelers do not need to replace every everyday expression for “taking medicine” with a formal term just to sound professional.
How do common Korean pharmacy phrases compare with Japanese pharmacy expressions?
Communication at Korean and Japanese pharmacies is very similar. When you need to buy medicine, you can describe your symptoms first and ask the pharmacist to assess the situation. If you are taking other medicine, have a drug allergy, or are not sure whether self-medication is appropriate for your current condition, you can also provide the relevant information directly.
In Korean, 「약사님과 상담하고 싶어요」is commonly used to say that you would like to consult a pharmacist, while in Japanese you can say 「薬剤師さんに相談したいです」. If you do not know the product name, neither language requires you to force yourself to name a specific medicine. You can begin by describing the symptoms, when they appeared, and the medicines you are currently using.
◆ Similar expressions: Common phrases at Japanese pharmacies
Common expressions at Japanese pharmacies generally do not require complex medical terminology. If you first explain that you would like a consultation, that you are taking another medicine, or that you want to know whether you should seek medical care, the pharmacist can continue asking questions based on that information.
- Example: 薬剤師さんに相談したいです。
Kana: やくざいしさんにそうだんしたいです。
Translation: I would like to consult a pharmacist.
This corresponds to the Korean 「약사님과 상담하고 싶어요」. Both the Japanese 「相談したいです」and the Korean 「상담하고 싶어요」state the purpose of seeking a consultation first, without assuming that a certain medicine must be suitable for the current condition. - Example: 今、飲んでいる薬があります。
Kana: いま、のんでいるくすりがあります。
Translation: I am currently taking medicine.
This corresponds to the Korean 「지금 복용 중인 약이 있어요」. Japanese uses 「飲んでいる薬」, while Korean uses 「복용 중인 약」, which is common in pharmacy and medical contexts. If you know the medicine’s name, you can then show the medicine bag, prescription, or product photo. - Example: 病院に行ったほうがいいですか。
Kana: びょういんにいったほうがいいですか。
Translation: Would it be better to go to a hospital?
This corresponds to the Korean 「병원에 가는 게 좋을까요?」. The Japanese 「〜たほうがいいですか」and the Korean 「-는 게 좋을까요?」both ask which course of action is more appropriate; they do not independently conclude that a hospital visit is definitely necessary.
◆ Key differences from common Korean pharmacy phrases:
Both Japanese and Korean allow you to describe your physical condition using everyday vocabulary without first memorizing complete medical terminology. Korean pharmacies commonly use forms such as 「아파요」「증상이 있어요」「복용 중이에요」, while Japanese commonly uses 「痛いです」「症状があります」「飲んでいます」to convey the same information. What actually affects communication is whether the symptom information is complete, including when the symptoms began, where they occur, what medicines you are currently taking, and whether you have allergies. If you do not know a product name, you can first say that you would like to consult a pharmacist in either language, then supplement the information with a medicine bag, prescription, product photo, or translation screen.
You do not need to memorize the Korean used to buy medicine at a Korean pharmacy as an entire dialogue. First explain “where you feel unwell and when it began,” then volunteer information about current medications, allergies, pregnancy, or breastfeeding. After receiving the product, confirm how to use it and what precautions you need to follow.
The distinction that truly matters is between “Korean for buying medicine” and “deciding for yourself which medicine to take.” You can prepare sentences for the former, but the latter should be left to a pharmacist or medical professional. If you encounter an emergency while traveling, seek help from 119 directly; you do not have to speak complete Korean first.
FAQs
You can begin with 「약을 찾고 있는데요」, which means “I’m looking for medicine.” If you do not have a specific product in mind, you can also say 「약사님과 상담하고 싶어요」to indicate that you would first like to consult the pharmacist, then add where you feel unwell and how long the symptoms have lasted.
You can say 「지금 복용 중인 약이 있어요」, meaning “I am currently taking medicine.” If you have the medicine bag, outer packaging, a product photo, or the ingredient name, it is best to provide it as well because simply saying that you take another medicine is still not enough to identify the actual product.
Both can be used when discussing oral medicine. 「먹다」is the everyday verb “to eat,” and 「약을 먹다」is very natural. 「복용하다」is the more formal “to take medicine” and is more common in pharmacies, medical contexts, and product instructions. You can ask either 「어떻게 먹어요?」or 「어떻게 복용하면 돼요?」.
You can use 「휴일지킴이약국」to search for pharmacies that are currently open, including holiday and late-night pharmacies. You can also ask 「지금 문 연 약국이 어디예요?」in Korean. Opening hours may change at short notice, so it is still appropriate to check again before going.
Korea’s emergency medical number is 119. The 1330 service primarily provides Korea travel information and multilingual assistance and should not replace emergency services. If your physical condition is already an emergency, contacting 119 directly is more appropriate.
