Valium is a brand name for the medication diazepam, which belongs to the benzodiazepine class of drugs. It is primarily prescribed for its anxiolytic (anti-anxiety), muscle relaxant, sedative, and anticonvulsant properties. Valium is commonly prescribed to manage generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder. Valium works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity. This results in calming effects, muscle relaxation, and sedation.
