Oxazepam is an intermediate-acting benzodiazepine prescribed for the treatment of anxiety disorders, panic disorders, alcohol withdrawal, and insomnia. It is characterized by relatively low potency compared to other benzodiazepines, a slow onset of action, and a simple metabolic profile that makes it less susceptible to variability based on age or liver function. It is notably an active metabolite of both diazepam and temazepam. Higher doses may produce amnesia and lowered inhibitions.
