Japan OTC Medicine Guide for Foreigners: Objective Procedures for Buying Cold Medicine and First Aid at Drugstores

This article is written by a Japanese local.

When you fall ill at night or on a holiday when hospitals are closed in Japan, your first line of defense is the “OTC (over-the-counter) medicines” sold at drugstores. However, with countless packages lined up on the shelves, all describing their efficacy in Japanese, foreigners face a severe infrastructure wall where “every box looks the same.”

Furthermore, Japanese OTC medicines have unique rules, such as lower dosage levels compared to Western medicines, and specific categories that require pharmacist approval for purchase. This article explains objective procedures to bypass the language barrier and lists the recommended OTC medicines you should stock up on immediately after relocating.

1. Classification and Purchase Restrictions of Japanese OTC Medicines

[Summary] Highly effective “Category 1 Medicines” legally require face-to-face explanation and written confirmation from a resident pharmacist. They cannot be purchased at night or when the pharmacist is absent.

OTC medicines sold in Japanese drugstores are classified from “Category 1” to “Category 3” based on the risk of side effects, and the rules for purchasing them are strictly regulated.

“Category 1 Medicines” (Dai-ichi-rui Iyakuhin), which are the most effective and include strong painkillers and stomach medicines, are kept behind the cash register or out of reach. To purchase these, it is an objective legal requirement to receive direct confirmation regarding side effects and your current medications from a licensed “Pharmacist” (Yakuzaishi), not just a registered salesperson. You must understand the practical limitation that even at a 24-hour drugstore, these medicines legally cannot be sold late at night or early in the morning after the pharmacist has clocked out.

2. Objective Indicators: “Cold Medicine” and “Painkillers” Expats Should Stock

[Summary] The most reliable practical procedure is to ask specifically for “Pabron” or “Lulu” for general cold symptoms, and “Loxonin S” or “EVE” for fever and pain relief.

Trying to decipher and compare the Japanese on packages is inefficient. The safest and most secure approach is to execute a “named purchase” of the following standard medicines that many Japanese people keep in their homes.

  • Comprehensive Cold Medicine: “Pabron” and “Lulu” are Japan’s standard household medicines, broadly addressing multiple symptoms like fever, sore throat, and runny nose.
  • Antipyretic Analgesics (Painkillers): For headaches, menstrual cramps, and fevers, choose “EVE” (active ingredient: Ibuprofen) or “Loxonin S” (active ingredient: Loxoprofen; *Category 1 Medicine). These function as direct alternatives to overseas medications like Advil or Motrin.

3. First Aid for Injuries and Burns: Japan’s “Moist Wound Healing” Infrastructure

[Summary] For scrapes and cuts, the current standard first aid procedure in Japan is “Moist Wound Healing”: wash the wound with water (do not use disinfectants) and apply a “Kizu Power Pad” directly.

The selection of adhesive bandages (Band-Aids) for children’s falls or burns during cooking has undergone unique evolution in Japan. Currently, the mainstream approach for first aid in Japanese medical settings and homes is “Moist Wound Healing,” which prevents the wound from drying out.

Products using hydrocolloid materials, such as “Band-Aid Kizu Power Pad,” are widely sold in drugstores. When using these, applying disinfectants (like hydrogen peroxide) will actually delay the healing process. Follow the objective procedure: wash the dirt away with tap water and apply the pad directly to the wound.

4. Practical Q&A (Dosage Strength and English Consultations)

[Summary] Japanese OTC medicines contain lower active ingredient dosages compared to Western medicines. When looking for medicine in-store, presenting a “memo of your symptoms” via a translation app is an essential defensive measure.

Q. I feel that Japanese OTC medicines are weaker than those in my home country.

A. This is due not only to differences in body size but also to legal regulations on ingredients. Japanese OTC medicines are designed with safety as the top priority, and the amount of active ingredient per dose is set lower compared to Western OTC drugs (like Tylenol). Simply because the effect feels weak, taking “more than the prescribed dose” drastically increases the burden on your internal organs and the risk of side effects, and must be absolutely avoided. If your condition does not improve with OTC medicine, transition to the procedure of visiting a clinic immediately.

Q. Can I consult a drugstore clerk about my symptoms in English?

A. Outside of a few stores in central urban areas, it is extremely rare for pharmacists or clerks to be able to provide medical explanations in English. Instead of trying to explain verbally, execute an objective defensive procedure: create a memo on your smartphone in advance translating your symptoms (e.g., Headache, Fever, Cough) and your drug allergy history into Japanese, and present this to the staff so they can select the right medicine for you.

Conclusion: Build Your “First Aid Kit” Immediately After Relocation

Holding up a translation app in front of the shelves of an unfamiliar Japanese drugstore after suddenly experiencing a midnight fever or injury is highly inefficient both mentally and physically. To establish a solid living foundation in Japan, execute a roadmap: immediately after your arrival, confirm the operating hours of your neighborhood drugstore and purchase a basic first aid kit containing “cold medicine, painkillers, stomach medicine, and bandages” to keep at home.
