Loperamide: Knowledge and Opinions of Its Safety

Background: Loperamide is a widely used over-the-counter antidiarrheal agent. While generally safe at recommended doses, inappropriate loperamide use may lead to constipation and other safety concerns. Understanding knowledge and perceptions of loperamide use is important for safe medication practices and patient counseling. Objective: To assess respondent knowledge and opinions regarding loperamide safety, regulation, and accessibility, and to examine demographic factors associated with these outcomes. Methods: A cross-sectional survey was conducted to collect demographic data and responses to five opinion-based questions and five knowledge-based questions related to loperamide and medication safety. Descriptive statistics were reported as frequencies and percentages. Pearson chi-square tests were used to evaluate associations between demographic variables and survey responses (p < .05). Results: A total of 49 respondents were included. Most respondents were female (72.3%) and reported completing a 4-year degree (67.4%). Opinion-based responses demonstrated high agreement across items. Knowledge-based responses demonstrated an overall average accuracy of 77.7%, with the lowest accuracy observed for the question assessing recommended maximum dosing (54.5%). Education level was significantly associated with two opinion-based items and one knowledge-based item, while years of work experience were associated with one knowledge-based outcome (p < .05). Conclusion: Respondents demonstrated strong agreement regarding loperamide safety and generally high knowledge, however, gaps remain in specific areas such as dosing and treatment selection. Education level and work experience were associated with selected outcomes, suggesting that training and clinical exposure may influence and improve medication safety knowledge and counseling practices.
