PMDA Alert for Proper Use of Drugs provides information on the proper use of pharmaceutical products for which patients applied for relief benefits or cases of adverse reactions were reported repeatedly, in spite of the fact that precautions for those drugs had been already issued in package inserts or in other ways. This page is intended to make easy-to-understand explanations using graphic illustrations on such safety matters to which healthcare professionals should pay attention, encouraging them to thoroughly continue the proper use of drugs.
