Diazepam is used to treat anxiety, acute alcohol withdrawal, and seizures. It is also used to relieve muscle spasms and to provide sedation before medical procedures. This medication belongs to a class of drugs called benzodiazepines which act on the brain and nerves (central nervous system) to produce a calming effect. It works by enhancing the effects of a certain natural chemical in the body (GABA). This medication may also be used to prevent extremely bad nightmares (night terrors).
