As part of a population study on the prevalence of psychopathology, users of "Over-The-Counter" Psychotropics (OTC-Ps) were studied. First, their mental health profile was examined by a number of subjective and objective assessments. Second, the medical consumption of the users was studied with special attention to the psychotropic drugs prescribed. The prevalence of psychological problems and symptoms of psychological distress was higher among OTC-P users than among non-users. Somatic problems and symptoms were comparable in the two groups; social support was better in the OTC-P users. Half of the users were known to have mental health problems by their Primary Care Physician (PCP). The DSM IV Axis I disorders were mostly mood and anxiety disorders. A benzodiazepine had been prescribed to one-third of the OTC-P users. No other psychotropic drugs had been prescribed, and the medical consumption was comparable in the two groups. PCPs should be aware of concomitant OTC-Ps use.
