Diazepam is mainly used to treat anxiety, insomnia, panic attacks, and symptoms of acute alcohol withdrawal. It is also used as a premedication for inducing sedation, anxiolysis, or amnesia before certain medical procedures (e.g., endoscopy). In 2020, it was approved for use in the United States as a nasal spray to interrupt seizure activity in people with epilepsy.Diazepam is the most commonly used benzodiazepine for “tapering” benzodiazepine dependence due to the drug’s comparatively long half-life, allowing for more efficient dose reduction. Benzodiazepines have relatively low toxicity in overdose.
