Function
Milk of magnesia contains magnesium hydroxide, a substance that does not dissolve in water. When used to treat constipation, the laxative draws water into the intestines and helps eliminate waste. The medication also works as an antacid to relieve heartburn and indigestion. Magnesium hydroxide helps neutralize too much stomach acid when the hydroxide ions mix with the hydrogen ions in hydrochloric acid.
Administration
Magnesium hydroxide is available in liquid or chewable tablets. Older children may take chewable tablets with ease, while younger children may do better with the liquid form. Give tablets and liquid medication with extra water or juice if your child has trouble with the taste or texture of milk of magnesium. Follow the instructions provided by your doctor or read the label for age-appropriate dosing.
Side Effects
Several side effects, including diarrhea, nausea, upset stomach and allergic reaction, may occur when taking magnesium hydroxide. Your child may experience frequent and loose bowel movements as a result of taking a laxative. Encourage fluids and contact your pediatrician if excessive diarrhea occurs. Magnesium hydroxide may irritate your child's stomach and lead to nausea or vomiting. Contact your pediatrician immediately if your child experiences facial swelling, shortness of breath, fever or a rash. These symptoms may indicate an allergic reaction, which may be life-threatening if left untreated.
