The elderly are more likely to have chronic medical conditions that require multiple drug therapies. Purposes of this study are to reveal necessity of elderly patient education by pharmacists, and to induce appropriate policy. We carried out literature research. Taking several drugs together increases risk of drug interactions and adverse reactions. We suggest that pharmacists have the legal authority to monitor prescription for efficient drug management, pharmacovigilance system be efficiently operated, and medication education fee be provided to allow pharmacists give more time to the elderly.
