This summary is based on the Rapid Response Report developed by the Canadian Agency for Drugs and Technologies in Health: High dose and watchful dosing of benzodiazepines: a review of the safety and guidelines Full Report (PDF) Key Findings No “watchful dose” for benzodiazepines was identified. Benzodiazepines may be used in higher than 10 mg diazepam-equivalent doses in some circumstances, but data were limited.
