Take diazepam only as directed by your doctor.

Your doctor will tell you how much of this medicine you should take. The dose varies from person to person depending on age and the condition being treated and whether you are taking any other medicines.

The usual adult dose is usually between 5 and 40 mg daily. Children, elderly and very ill patients may need to take less.
