Discontinuation of long-term benzodiazepine use: 10-year follow-up

Background. Several interventions aiming at discontinuation of long-term benzodiazepine use have been proven effective in the short term. However, data on the persistence of discontinuation are lacking. Objectives. To assess 10-year follow-up status in patients who succeeded in stopping benzodiazepine use after a discontinuation letter from the patient's own GP. To identify determinants of successfull discontinuation on the long term. Methods. Follow-up data of patients who participated in a large prospective, controlled stepped care intervention programme among long-term benzodiazepine users in primary care. Results. At 10-year follow-up, the percentage of benzodiazepine abstinence was 58.8%. Non-abstinent patients used lower doses of benzodiazepine. Being abstinent at 21 months after the intervention predicted abstinence at 10-year follow-up. Conclusions. Ten years after a minimal intervention to decrease long-term benzodiazepine use, the majority of patients who were able to discontinue benzodiazepine use initially, does not use benzodiazepines at 10-year follow-up. Patients who did not succeed in maintaining abstinence from benzodiazepines appear to use lower or average dosages.
