Warning

Midazolam may cause serious or life-threatening breathing problems such as shallow, slowed, or temporarily stopped breathing. Your child should only receive this medication in a hospital or doctor's office that has the equipment that is needed to monitor his or her heart and lungs and to provide life-saving medical treatment quickly if his or her breathing slows or stops. Your child's doctor or nurse will watch your child closely after he or she receives this medication to make sure that he or she is breathing properly. Tell your child's doctor if your child has a severe infection or if he or she has or has ever had any airway or breathing problems or heart or lung disease.

Why is this medication prescribed?

Midazolam is given to children before medical procedures or before anesthesia for surgery to cause drowsiness, relieve anxiety, and prevent any memory of the event. Midazolam is in a class of medications called benzodiazepines. It works by slowing activity in the brain to allow relaxation and sleep.

How should this medicine be used?

Midazolam comes as a syrup to take by mouth. It is usually given as a single dose by a doctor or nurse before a medical procedure or surgery.

What works?

  • Intravenous midazolam infusion for sedation of infants in the neonatal intensive care unit Intravenous midazolam infusion for sedation of infants in the neonatal intensive care unit
    There is no evidence to show the benefit of midazolam as a sedative for newborn babies in neonatal intensive care. Newborn babies undergoing uncomfortable procedures in intensive care units may need sedation to reduce stress and avoid complications. It is difficult to measure their pain so sedatives or pain killers are sometimes overlooked for newborn babies. Midazolam is a short acting sedative increasingly used in neonatal intensive care. The review of trials found no evidence to support the use of midazolam as a sedative for neonates undergoing intensive care. Babies receiving midazolam stayed in hospital longer and had more adverse effects. More research is needed to address the safety and effect of midazolam.
