Uses of This Medicine
Midazolam is used to produce sleepiness or drowsiness and to relieve anxiety before surgery or certain procedures. Midazolam is also given to produce amnesia (loss of memory) so that the patient will not remember any discomfort or undesirable effects that may occur after a surgery or procedure . It is also used to produce loss of consciousness before and during surgery. Midazolam is sometimes used in patients in hospital intensive care units to cause unconsciousness. This may allow the patient to withstand the stress of being in the intensive care unit and help the patient cooperate when a machine must be used to assist with breathing.
Midazolam is given only by or under the immediate supervision of a doctor trained to use this medicine. If you will be receiving midazolam during surgery, your doctor or anesthesiologist will give you the medicine and closely follow your progress.

After you receive midazolam, you will be watched closely to make sure the medicine is working. Your breathing, blood pressure, nervous system, and heart will also be watched closely to make sure the medicine is not causing unwanted side effects.
Drugs and Foods to Avoid
Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.
Before you are given midazolam, make sure your doctor knows if you are using other medicines that may make you sleepy such as sleeping pills, tranquilizers, some cold and allergy medicine, narcotic pain-killers, or medicines that relax your muscles. Tell your doctor if you drink alcohol. You may get too drowsy or sedated if you drink alcohol or use medicines that cause drowsiness with midazolam.
Wait about 24 hours (or as your doctor orders) before drinking alcohol or using medicines that cause drowsiness.
