From the Research

Maalox is not recommended for children under 12 years old without a doctor's supervision, and for a 9-year-old child, it's best to consult with a pediatrician before giving Maalox. The medication contains aluminum hydroxide and magnesium hydroxide, which may not be appropriate for young children at standard adult doses 1, 2. If a doctor does approve Maalox use, they would likely recommend a reduced dose based on the child's weight and specific condition.

Alternative Options

Instead of Maalox, consider more age-appropriate options like:

  • Children's Pepto-Bismol
  • Tums (calcium carbonate) which have specific pediatric dosing guidelines 2. For temporary relief of minor stomach discomfort in children, non-medication approaches like:
  • Small sips of clear fluids
  • Bland foods
  • Rest may help 3, 4.

Reason for Caution

The reason for caution is that children metabolize medications differently than adults, and antacids can potentially mask symptoms of more serious conditions that would require different treatment 5. It is crucial to prioritize the child's safety and consult with a pediatrician before administering any medication, including Maalox.
