Uses
This medication is used to treat a certain sleep problem (insomnia). It may help you fall asleep faster, stay asleep longer, and lessen how often you wake up during the night, so you can get a better night's rest. Flurazepam belongs to a class of drugs called benzodiazepines. It acts on your brain to produce a calming effect.
Use of this medication is usually limited to treatment periods of 1 to 2 weeks or less. If your insomnia continues for a longer time, talk to your doctor to see if you need other treatment.

Although unlikely, this drug can rarely cause temporary short-term memory loss. To lessen the chance of this, do not take a dose of this drug unless you have time for a full night's sleep of at least 7 to 8 hours. If you have to wake up before that, you may have some memory loss.
