What HYPNOVEL is used for
HYPNOVEL tablets are used for the short term treatment of insomnia.
HYPNOVEL tablets may be given to you before an operation to produce sleepiness or drowsiness and to relieve anxiety.
HYPNOVEL belongs to a group of medicines called benzodiazepines. They are thought to work by their action on brain chemicals. HYPNOVEL tablets will cause sedation, and help you to sleep.
Your doctor, however, may have prescribed HYPNOVEL for another purpose. Ask your doctor if you have any questions about why HYPNOVEL has been prescribed for you.
If you will be receiving HYPNOVEL before minor surgery, your doctor will give you the medicine and closely follow your progress.
This medicine is available only with a doctor's prescription.
