SN instructed that Temazepam is used to treat sleep problems (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. Temazepam belongs to a class of drugs called sedative-hypnotics. It acts on your brain to produce a calming effect. SN also instructed on side effects such as, dizziness or difficulty with coordination. If either of these effects persists or worsens, tell your doctor or pharmacist promptly. To reduce the risk of dizziness or falling, get up slowly when rising from a sitting or lying position.
