Abstract

Background: Improperly disposed medicines could adversely affect the environment and increase the risk of drug misuse or accidental poisoning. Objective: To evaluate the disposal practices of unused and expired medicines among the general population in Bandung, Indonesia. Method: This was a descriptive cross-sectional survey conducted among 497 respondents in Bandung, Indonesia. Data were collected through interviews using a prevalidated structured questionnaire. Descriptive statistics were calculated using the Statistical Package for Social Science (SPSS) version 23. Ethics approval was obtained. Main outcome measure: General public knowledge and attitude regarding unused and expired medication disposal practice. Results: Approximately 95% of the respondents had unused medicines stored in their homes, with nonsteroidal anti-inflammatory drugs (NSAIDs), vitamins/nutritional supplements, and antibiotics were the most common types of medicines left unused. The majority of the respondents checked the expiration date of the drugs before purchasing (72.8%). The most common disposal method of unwanted medicines was throwing away in household garbage (82.1%). A significant percentage of them never received information about proper medication disposal practice (79.5%). Furthermore, more than half of the respondents were unaware that unsafe medication disposal practices could harm the environment and population health (53.1%). Conclusion: Disposal of unwanted pharmaceutical products through environmentally unsafe route was prevalent among the respondents. There is also a lack of awareness of the impact of improperly disposed of medicines for the ecosystem. These findings call upon the strategies to strengthen the pharmaceutical waste management program.
