Valium, also known as diazepam, is a prescription medication commonly prescribed for anxiety disorders, muscle spasms, and alcohol withdrawal symptoms. As a benzodiazepine, it enhances the effects of gamma-aminobutyric acid (GABA) in the brain, producing a calming effect. Valium should be used cautiously due to the risk of dependency and side effects like drowsiness and dizziness. It's essential to obtain Valium through a licensed healthcare provider's prescription.
