Diazepam is a medication that belongs to the benzodiazepine class of drugs. It's commonly used to treat anxiety, muscle spasms, seizures, and alcohol withdrawal symptoms. Diazepam works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain, which leads to a calming effect.It's available in various forms, including tablets, oral solution, and injection. However, it's typically prescribed for short-term relief due to its potential for tolerance, dependence, and withdrawal symptoms if used long-term.
