Iron Deficiency Anemia Treatment in Children

Treatment and Administration

• The Centers for Disease Control and Prevention recommends administering 3 mg/kg/day of elemental iron in the form of drops, preferably between meals, for children with iron deficiency anemia 1, 2
• Treatment should continue for 2 months after hemoglobin levels normalize, for a total of approximately 3 months of treatment 3
• Administering iron between meals improves absorption, although it may increase gastrointestinal side effects 3

Monitoring and Follow-up

• Hemoglobin testing should be repeated after 4 weeks of treatment 2
• An increase in hemoglobin concentration ≥1 g/dL or hematocrit ≥3% confirms the diagnosis of iron deficiency anemia 2
• If iron deficiency anemia is confirmed, dietary counseling should be reinforced and iron treatment continued for 2 more months 2

Special Considerations

Primary Prevention

• For children aged 1-5 years, cow's milk, goat's milk, or soy milk consumption should be limited to no more than 24 oz (approximately 720 ml) per day 4
• Foods rich in vitamin C (fruits, vegetables, or juices) should be included to improve iron absorption, preferably with meals 4
• Meat purees should be introduced after 6 months or when the baby is ready to consume this type of food 4

Risk Factor Evaluation

• Children at higher risk of iron deficiency anemia include:
  • Premature or low-birth-weight infants 4
  • Children consuming more than 24 oz of cow's milk daily 4
  • Children with special medical needs 4

Situations Requiring Special Attention

Lack of Response to Treatment

• If anemia does not respond to iron treatment after 4 weeks, despite adherence to the supplementation regimen and absence of acute illness, further evaluation of anemia is necessary through laboratory tests, including MCV, RDW, and serum ferritin concentration 2
• A serum ferritin concentration ≤15 μg/L confirms iron deficiency, while a concentration >15 μg/L suggests that iron deficiency is not the cause of anemia 2, 5
