Generic Name: diazepam (dye-AZ-e-pam)
Brand Name: Generic only. No brands available.
Diazepam is used for:
Treating anxiety disorders or for the short-term relief of the symptoms of anxiety. It is also used to treat seizures, certain types of muscle spasms, and symptoms of alcohol withdrawal (eg, agitation, tremor, hallucinations). Diazepam is also used before surgery or other medical procedures to help reduce anxiety and tension. It may also be used for other conditions as determined by your doctor.
Diazepam is a benzodiazepine. It works by increasing the action of a certain chemical (gamma-aminobutyric acid [GABA]) in the brain and nervous system. This helps to reduce anxiety. It also helps to reduce seizure activity in the brain and to reduce muscle spasms.
Do NOT use diazepam if:
- you are allergic to any ingredient in diazepam
- you have acute narrow-angle glaucoma or untreated open-angle glaucoma, certain muscle problems (eg, myasthenia gravis), severe liver problems, severe breathing problems, or sleep apnea

When used for long periods of time or at high doses, diazepam may not work as well and may require higher doses to obtain the same effect as when originally taken. This is known as TOLERANCE. Talk with your doctor if diazepam stops working well. Do not take more than prescribed.
