How does oxazepam work?
As a benzodiazepine, oxazepam enhances the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABAA receptor, resulting in increased inhibitory effect in the brain. This action leads to sedative, hypnotic, anxiolytic, anticonvulsant, and muscle relaxant properties [2].
What is the typical dosage for oxazepam?
Dosages for oxazepam vary depending on the condition being treated and the patient's response. For anxiety, typical dosages range from 10 mg to 30 mg, taken three to four times daily [1]. For insomnia, a dose of 15 mg to 30 mg is usually taken at bedtime [1].

Oxazepam typically begins to take effect within 30 to 60 minutes after administration [4]. Its effects can last for several hours.

Oxazepam carries a risk of dependence and withdrawal. Abrupt cessation after prolonged use can lead to withdrawal symptoms such as anxiety, insomnia, and irritability [3]. It should be used with caution in elderly patients and those with impaired liver or kidney function [1]. Combining oxazepam with alcohol or other central nervous system depressants can increase the risk of severe sedation and respiratory depression [1].
