Valium, the brand name for diazepam, is a prescription medication that belongs to the benzodiazepine class. It is commonly used to treat anxiety, muscle spasms, seizures, and alcohol withdrawal symptoms. Valium is prescribed for the treatment of anxiety disorders, muscle spasms, seizures, alcohol withdrawal symptoms, and for sedation before medical procedures. It may also be used to manage symptoms of panic disorders. Diazepam works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity, leading to a calming effect on the nervous system.
