AUDIENCE: Consumer, Surgery, Anesthesiology

ISSUE: FDA has approved previously announced label changes regarding the use of general anesthetic and sedation medicines in children younger than 3 years. These changes include:

  1. A new Warning stating that exposure to these medicines for lengthy periods of time or over multiple surgeries or procedures may negatively affect brain development in children younger than 3 years.
  2. Addition of information to the sections of the labels about pregnancy and pediatric use to describe studies in young animals and pregnant animals that showed exposure to general anesthetic and sedation drugs for more than 3 hours can cause widespread loss of nerve cells in the developing brain; and studies in young animals suggested these changes resulted in long-term negative effects on the animals' behavior or learning.

General anesthetic and sedation drugs are necessary for patients, including young children and pregnant women, who require surgery or other painful and stressful procedures. In the U.S., surgeries during the third trimester of pregnancy requiring general anesthesia are performed only when medically necessary and rarely last longer than 3 hours. FDA is advising that in these situations, pregnant women should not delay or avoid surgeries or procedures during pregnancy, as doing so can negatively affect themselves and their infants.

Similarly, surgeries or procedures in children younger than 3 years should not be delayed or avoided when medically necessary. Consideration should be given to delaying potentially elective surgery in young children where medically appropriate.

BACKGROUND: This is an update to the MedWatch alert "General Anesthetic and Sedation Drugs: Drug Safety Communication - New Warnings for Young Children and Pregnant Women", available at: http://bit.ly/2pmujDk, issued on December 14, 2016.

RECOMMENDATION: Health care professionals should continue to follow their usual practices of patient counseling including discussing the benefits and risks of surgeries or procedures that require general anesthesia and sedation drugs. FDA will continue to monitor the use of these drugs in children and will update the public if additional information becomes available.

Parents, caregivers, and pregnant women should talk to their health care professionals if they have any questions or concerns about general anesthesia and sedation drugs.

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. Tell your child's doctor and pharmacist if your child is taking any of the following medications: antidepressants; barbiturates such as secobarbital (Seconal); droperidol (Inapsine); medications for anxiety, mental illness, or seizures; narcotic medications for pain such as fentanyl (Actiq, Duragesic, Sublimaze, others), morphine (Avinza, Kadian, MS Contin, others), and meperidine (Demerol); sedatives; sleeping pills; or tranquilizers.

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.
