What is temazepam?

Temazepam is a benzodiazepine (ben-zoe-dye-AZE-eh-peen). It affects chemicals in the brain that may be unbalanced in people with sleep problems (insomnia).

Temazepam is used short term to treat insomnia (trouble falling or staying asleep).

Temazepam works by slowing down the central nervous system (brain), causing drowsiness which helps patients fall asleep.
