Ferrous Sulfate Dosing in Pediatrics: A Comprehensive Guide

Introduction
Ferrous sulfate is a commonly prescribed iron supplement for treating and preventing iron deficiency anemia in children. Proper dosing is critical to ensure efficacy while minimizing side effects such as gastrointestinal discomfort. This article provides evidence-based guidelines for ferrous sulfate dosing in pediatric patients.

Recommended Dosage for Children
The American Academy of Pediatrics (AAP) recommends the following ferrous sulfate dosing for pediatric patients:

– Infants (1–12 months): 3–6 mg/kg/day of elemental iron, divided into 1–2 doses.
– Toddlers & Preschoolers (1–5 years): 3–6 mg/kg/day, up to a maximum of 60 mg/day.
– School-Age Children (6–12 years): 3–6 mg/kg/day, up to 120 mg/day.
– Adolescents (13–18 years): 60–120 mg/day, depending on severity of deficiency.

Elemental iron content varies by formulation—ferrous sulfate typically contains 20% elemental iron (e.g., 325 mg tablet = 65 mg elemental iron).

Administration Tips
– Give between meals for optimal absorption (vitamin C can enhance uptake).
– Avoid concurrent administration with calcium-rich foods or antacids.
– Monitor for constipation, nausea, or dark stools—common but manageable side effects.

Monitoring & Follow-Up
– Recheck hemoglobin levels after 1 month of therapy.
– Continue supplementation for 2–3 months after hemoglobin normalizes to replenish iron stores.

Conclusion
Correct ferrous sulfate dosing in pediatrics is essential for treating iron deficiency anemia safely and effectively. Always tailor the dosage based on age, weight, and clinical response while monitoring for adverse effects. Consult a pediatrician for personalized recommendations.
