Several medications are approved for treating insomnia (trouble sleeping). And some techniques can be used to help improve sleep. 

If you’re thinking about taking diazepam off-label for sleep, keep in mind that diazepam is a controlled substance.

How diazepam is taken

Diazepam comes as a tablet that you take by swallowing, with or without food. In some cases, it’s taken two to four times per day. But for some conditions or in people of certain ages, it’s taken once per day.

As your treatment with diazepam ends, your doctor may slowly decrease your dosage. Doing so can help prevent withdrawal symptoms. (Withdrawal symptoms can occur when you stop taking a drug your body is dependent on. With dependence, your body needs the drug in order to function like usual.)*
