Hazardous Benzodiazepine Regimens in the Elderly: Effects of Half-Life, Dosage, and Duration on Risk of Hip Fracture

Abstract

Even at modest doses, including some low doses currently advocated in prescribing guidelines for older patients, treatment with benzodiazepines appears to increase the risk of hip fracture. Patients appear to be particularly vulnerable immediately after initiating therapy and after more than 1 month of continuous use. Benzodiazepines with shorter half-lives appear to be no safer than longer half-life agents. Clinicians should be aware of these risks and weigh them against potential benefits when prescribing for elderly patients.
