Can Diazepam Help You Sleep If You Have Anxiety? Diazepam, commonly known by its brand name Valium, is a benzodiazepine medication primarily used to treat anxiety, muscle spasms, and seizures. It also has sedative properties, which means it can help promote sleep - especially for individuals whose insomnia is triggered by anxiety.
