Discharge Instructions for Hypermagnesemia (Child)

Choose a preferred language


Your child has too much magnesium in their blood. This is called hypermagnesemia. This can happen if a child's kidneys are failing. It also can be caused by medicines that contain magnesium, such as laxatives, antacids, or magnesium salts. A baby can be born with this problem if too much magnesium was taken during pregnancy. In the hospital, treatments are given to lower blood magnesium levels. Here's what you need to know to care for your child at home.


Diet changes

Limit your child's intake of all foods that have magnesium in them. These include the following:

  • Spinach.
  • Nuts.
  • Soy products.
  • Whole-grain cereals (bran flakes, shredded wheat, oatmeal).
  • Millet, wheat bran, wheat germ.
  • Brown rice.
  • Dried beans.
  • Avocado.
  • Dried apricots.


Other home care

  • Don't give your child antacids or laxatives unless told to by your child's doctor.
  • Don't give your child an enema that has magnesium in it. If your child needs an enema, read the label carefully.
  • Tell your child's doctor about all prescription and over-the-counter medicines, supplements, or herbal drugs your child takes. Some of them can increase magnesium levels.
  • Give your child all medicines exactly as directed.
  • Learn to take your child's pulse. Tell your child's doctor if your child's pulse rate is slower than 60 beats a minute.


Follow-up care

  • Follow up with your child's doctor, or as advised.
  • Have your child's magnesium levels checked as directed.
  • Keep all follow-up appointments. Your child's doctor needs to watch your child's condition closely. This is very important if your child has another medical problem causing the hypermagnesemia.


When to contact your doctor

Contact your child's doctor right away if your child has:

  • Weakness or fatigue.
  • Trouble breathing or shortness of breath.
  • Irregular or slow heartbeat (pulse).
  • Fainting or loss of consciousness.
  • Dizziness or lightheadedness.
  • Confusion or changes in behavior.
  • Chest pain.
