Pediatric Iron Deficiency and Iron Deficiency Anemia Management

Dosing Recommendations

• For breast-fed infants who receive insufficient iron from supplementary foods by age 6 months, the Centers for Disease Control and Prevention recommends administering 1 mg/kg/day of iron drops 1
• For breast-fed infants who were preterm or had low birthweight, the Centers for Disease Control and Prevention recommends administering 2-4 mg/kg/day of iron drops (maximum 15 mg/day) starting at 1 month after birth until 12 months 1
• When exclusive breastfeeding is stopped, the Centers for Disease Control and Prevention recommends providing an additional source of iron (approximately 1 mg/kg/day), preferably from supplementary foods 2
• For children with chronic kidney disease, the National Kidney Foundation recommends standard oral iron supplementation of 2-3 mg/kg/day of elemental iron in divided doses 3, 4
• For children on parenteral nutrition who cannot tolerate enteral iron, the European Society for Clinical Nutrition and Metabolism recommends providing 50-100 μg/kg/day up to a maximum of 5 mg/day 5, 6

Iron Formulations and Administration

• The National Kidney Foundation recommends that ferrous sulfate is the preferred formulation due to better clinical response, fewer side effects, and cost-effectiveness, with 65 mg elemental iron per 325 mg tablet 4
• The National Kidney Foundation recommends administering oral iron between meals or at bedtime for optimal absorption 4
• Food can reduce iron absorption by up to 50% if eaten within 2 hours before or 1 hour after an iron supplement, according to the National Kidney Foundation 4

Monitoring and Common Pitfalls

• The American Society of Hematology recommends assessing response to therapy by measuring hemoglobin after 1 month of treatment 7
• The American Society of Hematology defines adequate response as hemoglobin rise of ≥1.0 g/dL and normalization of ferritin and transferrin saturation 7
• The European Society for Clinical Nutrition and Metabolism recommends regularly monitoring iron status (at least ferritin and hemoglobin) to prevent iron deficiency or overload in patients on long-term parenteral nutrition 6, 8
• The European Society for Clinical Nutrition and Metabolism warns that exceeding recommended doses can lead to significant adverse effects, including hepatocellular damage 5, 6
• The National Kidney Foundation notes that aluminum-based phosphate binders can reduce iron absorption 4
• The Centers for Disease Control and Prevention warns that cow's milk consumption exceeding 24 oz daily can interfere with iron absorption and contribute to iron deficiency 1, 2
• The Centers for Disease Control and Prevention recommends including vitamin C-rich foods with meals to improve iron absorption 2

Iron Deficiency Anemia Treatment in Pediatric Patients

Critical Safety Considerations

• The American Journal of Kidney Diseases recommends that for IV iron dextran test dosing, 10 mg should be used for children <10 kg, 15 mg for children 10-20 kg, and 25 mg for children >20 kg, and personnel trained in emergency treatment should be available when administering IV iron, with immediate access to epinephrine, diphenhydramine, and corticosteroids 9

CDC Guidelines for Pediatric Iron Supplementation and Screening

Infants (0–12 Months)

Term, Breastfed Infants

• For exclusively breastfed term infants, iron supplementation is unnecessary until 6 months of age; thereafter provide 1 mg elemental iron per kg per day if complementary foods do not supply sufficient iron. 10

• Between 6 and 12 months, if iron‑rich complementary foods provide less than 1 mg kg⁻¹ day⁻¹, give iron drops at 1 mg kg⁻¹ day⁻¹. 10

• Introduce iron‑fortified infant cereal at 4–6 months; offering two or more servings daily generally meets the infant’s iron requirement. 10

Term, Formula‑Fed Infants

• Use only iron‑fortified infant formula (containing 4–8 mg L⁻¹, equivalent to ≈0.6–1.2 mg kg⁻¹ day⁻¹) from birth through 12 months. 10

• Do not give low‑iron milks (cow, goat, or soy milk) before 12 months of age. 10

Preterm or Low‑Birth‑Weight Infants (Breastfed)

• Begin iron drops at 1 month of age at 2–4 mg kg⁻¹ day⁻¹ (maximum 15 mg day⁻¹) and continue until 12 months to support catch‑up growth and compensate for low neonatal iron stores. 10

Preschool Children (1–5 Years)

• Children should obtain iron mainly from diet, emphasizing iron‑fortified foods and meat products as primary sources. 10

• Limit intake of cow’s, goat’s, or soy milk to ≤ 24 oz (≈ 710 mL) per day to avoid interference with iron absorption. 10

• Include vitamin C‑rich foods with meals to enhance non‑heme iron absorption. 10

Screening Recommendations

High‑Risk Populations

• For children identified as high‑risk (e.g., low‑income, WIC‑eligible, migrant, or refugee), screen for iron deficiency at 9–12 months, repeat 6 months later, and then annually from ages 2 to 5 years. 10

Standard‑Risk Populations

• In standard‑risk children, perform selective screening only when specific risk factors are present. 10
