Medicine in Japan: Compare US & Japanese OTC Medicines | Japanese Pharmacist

Looking for a medicine in Japan that contains the same active ingredient as one you use at home?

A Japanese pharmacist compares OTC medicines sold in Japan. You can compare active ingredients and strengths.

Brand names and packaging may look similar—or completely different—between countries. Even when two products contain the same active ingredient, the strength, dosage, additional ingredients, and approved uses may differ.

This site does not assume that two medicines are equivalent. Instead, it provides factual comparisons to help you understand the differences between overseas and Japanese OTC medicines.
