MEDICINE FINDER

Know what is in the box.

Japanese over-the-counter medicines, explained from the label, with the brands you know from home.

Look up Japanese over-the-counter medicines by name, ingredient or the brand you use at home.

This shows what each box’s label says: active ingredients, the label’s own uses and the sales class. It does not tell you what to take. Show the box to the pharmacist and ask before you buy, especially if you take other medicines, are pregnant or are buying for a child. Care Compass Japan provides navigational guidance, not medical diagnosis or treatment advice. If you are experiencing symptoms, please consult a qualified healthcare professional or visit an accredited hospital/clinic.
