Benzodiazepine use in general practice--is it a problem?

Abstract

Aims: The aim of this study was to describe benzodiazepine use in a general practice.

Methods: A prevalence study in an Auckland general practice was undertaken to describe the benzodiazepines prescribed, patterns of use and compliance. An associated case control study compared benzodiazepine users and nonusers.

Results: The age standardised prevalence rate of benzodiazepine use in this Auckland general practice was 3.4% for patients over 20 years of age. The benzodiazepine users described were predominantly elderly (70% over 60 years of age) and female (62.5%). They had significantly more medical and psychiatric complaints than matched controls. Triazolam and diazepam accounted for 60.9% of the benzodiazepines prescribed. Over one-third of the patients using benzodiazepines were concurrently prescribed other psychotropic medications, primarily tricyclic antidepressants.

Conclusion: This rate suggests an overall decline in benzodiazepine use since previous studies. Benzodiazepines continue to be prescribed predominantly in the elderly, a group at considerable risk from side effects. Doctors should continue to inform their patients about the side effects of benzodiazepines, the risks of dependence and difficulties of withdrawal.
