Study on withdrawal of hypnotics: questionnaire on hypnotic use and its withdrawal

To investigate the situation and problems contingent to hypnotic use and withdrawal, we conducted a questionnaire of outpatients. Only 41% of the patients were satisfied with their sleep and 53% of the patients took hypnotics. As regards the period, 83% of users had used them for more than 1 year and 19% had used them for more than 10 years. Although 90% of patients perceived efficacy of hypnotics, 67% felt more or less anxious about hypnotic use. Sixty-seven per cent of patients had actually withdrawn from the drugs or decreased dosage before. More than half the patients' conditions worsened after the withdrawal or reducing dosage.
