Clinical Characteristics of Over‐The‐Counter Drug Misusers in Psychiatric Practice in Japan: Comparison Between Codeine Misusers and Dextromethorphan Misusers

Furthermore, preventive education incorporating perspectives on mental-health-focused suicide prevention, as well as regulatory measures for OTC medication sales, are urgently needed.
