1. Why am I using Hypnovel?

Hypnovel contains the active ingredient Midazolam. Hypnovel belongs to a group of medicines called benzodiazepines. They are thought to work by their action on brain chemicals. Hypnovel can cause sedation, hypnosis, amnesia and/or anaesthesia, depending on the dose.

Hypnovel may be injected as a sedative during some short medical procedures.

Hypnovel may be given to you by injection before an operation to produce sleepiness or drowsiness and to relieve anxiety.

If you are in an intensive care unit, you may receive an infusion of Hypnovel over several hours or days as a sedative.

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.

Hypnovel is only given by a doctor trained to use this medicine. If you will be receiving Hypnovel during surgery, your doctor will give you the medicine and closely follow your progress.

This medicine is available only with a doctor’s prescription.

4. How am I given Hypnovel?

How Hypnovel is given

  • Hypnovel may be given to you as an injection into a vein or muscle. It may also be given through an infusion set in an intensive care unit. Other medications may also be given at the same time.

When and how long Hypnovel is given

  • Hypnovel may be given once before a medical procedure, or continuously by infusion for patients in an intensive care unit.
  • Hypnovel will be stopped once there is no further need for sedation.

How much is given

  • Your doctor will adjust the dose necessary for you.

This depends on which medical procedure you will be having, your age, weight and your general health. Elderly patients may need to receive less.

If you have been given too much Hypnovel

If you think that you have used too much Hypnovel, you may feel drowsy, tired, confused, dizzy, feel weak or become unconscious. If used in combination with other similar medicines, the effects of overdose may be serious and potentially fatal. You may need urgent medical attention.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how Hypnovel affects you.

Hypnovel may cause dizziness, drowsiness, dizziness, fatigue, confusion and forgetfulness in some people and therefore may affect alertness. Make sure you know how you react to Hypnovel before you drive a car or operate machinery, or do anything else that could be dangerous if you are drowsy, dizzy or not alert.

Drinking alcohol

Do not have any alcohol for at least 12 hours after you have been given Hypnovel.

In elderly, or high-risk patients, death has resulted on rare occasions, due to heart attack or a slowdown of the heart and lungs. These life-threatening diseases are more common in adults over 60 years of age and with pre-existing heart and lung conditions when a high dose of Hypnovel is administered or when the injection is given too rapidly. If you belong to these high-risk groups seek medical attention immediately if you notice heart or breathing issues.
