Proper Use

Midazolam will be given to you or to your child in a hospital or clinic by a doctor trained to use this medicine. If you or your child will be receiving midazolam during surgery, your doctor or anesthesiologist will give you the medicine.

After you receive midazolam, you or your child will be watched closely to make sure this 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.

Precautions

If you will be receiving midazolam before surgery, your doctor will give you the medicine and closely follow your progress, to make sure this medicine is working properly and to check for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using this medicine, tell your doctor right away.

For patients going home within 24 hours after receiving midazolam:

• Midazolam may cause some people to feel drowsy, tired, or weak for 1 or 2 days after it has been given. It may also cause problems with coordination and one's ability to think. Therefore, do not drive, use machines, or do anything else that could be dangerous if you are not alert until the effects of the medicine have disappeared or until the day after you receive midazolam, whichever period of time is longer.
• Do not drink alcoholic beverages or take other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness) for about 24 hours after you have received midazolam, unless otherwise directed by your doctor. To do so may add to the effects of the medicine. Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; other sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; medicine for seizures; and muscle relaxants.
