Valium 10 mg tablets contain diazepam, a benzodiazepine used to treat severe anxiety, muscle spasms, seizures, and alcohol withdrawal. It works by increasing GABA (a calming chemical) in the brain to sedate the nervous system. It is usually taken 1–2 times daily, but it is habit-forming and meant for short-term use.
