What is diazepam?
Diazepam is in a group of drugs called benzodiazepines (ben-zoe-dye-AZE-eh-peens). Diazepam affects chemicals in the brain that may become unbalanced and cause anxiety.
Diazepam is used to treat anxiety disorders, alcohol withdrawal symptoms, or muscle spasms. Diazepam is sometimes used with other medications to treat seizures.
Diazepam may also be used for other purposes not listed in this medication guide.
Diazepam may be habit-forming and should be used only by the person it was prescribed for. Diazepam should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.
You should not use this medication if you are allergic to diazepam, or if you have:
- myasthenia gravis (a muscle weakness disorder);
- severe liver disease;
- narrow-angle glaucoma;
- a severe breathing problem; or

If you have certain conditions, you may need a dose adjustment or special tests to safely take diazepam. Before taking diazepam, tell your doctor if you are allergic to any drugs, or if you have:
