What is this medication for?

Diazepam belongs to the class of medications called benzodiazepines, a class used for its sedative effects. This medication works by increasing gamma-aminobutyric acid (GABA - a nerve messenger) in the brain. When GABA increases, unwanted nerve activity in the brain decreases. Diazepam is used for the short-term relief of symptoms of excessive anxiety or alcohol withdrawal (such as agitation and hallucinations). It is also used for the reduction of muscle spasms. It may also be used to treat seizure disorders in combination with other medications.

The injectable form of this medication is used to control prolonged seizures.

Your doctor may have suggested this medication for conditions other than those listed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.

How should I use this medication?

The recommended dose of diazepam by mouth for adults ranges from 2 mg to 10 mg 2 to 4 times daily with or without food. For children older than 6 months, the initial dose of diazepam by mouth usually ranges from 1 mg to 2.5 mg 3 or 4 times daily. Doses of diazepam injection vary depending on the condition being treated and range from 2 mg to 20 mg. It is important that the dose be individualized to your specific needs to avoid excessive drowsiness or loss of coordination.

Diazepam is normally used for a short period of time or as an "as needed" medication. It may be habit-forming when taken for long periods of time.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications.
