Comparing the Dosing Period in Package Inserts of Antimicrobial Agents Between Japan and the United States

The duration of antimicrobial therapy is a critical evaluation index of antimicrobial stewardship (AS). The inclusion of the dosing period on package inserts provides a strong reason for clinical intervention by pharmacists in cases where physicians prescribe inappropriate dosing periods. This study investigated differences in the description of dosing periods in antimicrobial package inserts between Japan and the U.S.

It was found that the information on the duration of administration was missing from the package insert in Japan compared to the U.S. Lack of information on the duration of administration may lead to long-term administration by the treating physician and also make it difficult for the pharmacist to inquire about the administration.
