市販薬を成分・リスク区分で比較|クスリノコンパス

Starting in March 2027, prescription drugs with the same ingredients as over-the-counter medications (such as Loxonin, Allegra, Hyloid, and 77 other ingredients) will incur an additional "surcharge" of one-quarter of the drug cost. However, almost no one can check from ingredient names whether their own medication is subject to this charge.

This tool allows you to simply photograph your medication handbook or medicine bag with your smartphone to instantly display:

• Which drugs are subject/not subject to the surcharge
• How much the cost will increase (drug price × quantity ÷ 4, calculated separately for 10-30% copay rates)
• Whether there are over-the-counter drugs with the same ingredients

It works with any number of medications on a single image. You can correct the drug names read in the confirmation screen. Results can be sent to family via LINE, so children can check medications for parents living far away.

Drug prices are based on the Ministry of Health, Labour and Welfare's drug price standard list (688 medical products), and target ingredients are estimated based on the Ministry's proposal. Photos are not saved, and only drug names are read—not names or other personal information. No registration required, free, and ad-free. This is not intended to encourage switching to over-the-counter drugs, but rather to provide information for decision-making.
