Essential Information

1

Warn families that stools may turn tarry green/black and constipation is common—this is not GI bleeding unless accompanied by pain or dizziness.

2

Separate iron from calcium, dairy, and antacids by 2 hours to enhance absorption and limit GI upset.

3

Store iron securely in child-resistant packaging; accidental overdose can be life-threatening.

Clinical Overview

Nausea, abdominal cramps, constipation, and dark stools are expected. Rarely, liquid formulations stain teeth or cause hypersensitivity.

Parent Communication Guide

Age-Appropriate Explanations

Infants (0-12 months)

For babies taking Elemental Iron, watch for signs of side effects. This medication is generally well-tolerated in infants when used as directed.

Toddlers (1-3 years)

If your toddler is taking Elemental Iron, they might feel different. This is usually temporary and normal.

Children (4-12 years)

This medicine helps your blood carry oxygen. Your poop may look darker—that is normal. Drink water and tell us if your tummy hurts.

Adolescents (13+ years)

Take iron with juice, not dairy, and space it from other meds. Lock it up so younger siblings cannot access it.

A: Try dosing after a small snack or at bedtime. If discomfort continues, contact the clinic for dosing adjustments.

When to validate: Call if vomiting or pain persists beyond 48 hours.

Q: Constipation
