 The purpose of this study was to assess the rational drug use of elderly patients visiting a primary care center. A survey was conducted to gather information about the drug usage habits of these patients. The results showed that 53.3% of the participants kept leftover medications at home. Additionally, when asked about their unprescribed drug usage, 60.8% of the participants reported not using any unprescribed drugs. This suggests that there is a need for better education regarding rational drug use among elderly patients. This article was authored by Bahadur Yazissioglu and Aleph Dikmetis Yarden.
