Iron Deficiency Anemia Treatment in Infants

Dosing Recommendations

For a 6-month-old infant with iron deficiency anemia, the Centers for Disease Control and Prevention recommends administering Maltofer (iron polymaltose) syrup at 3 mg/kg/day of elemental iron, given between meals for optimal absorption 1, 2, 3
The American Academy of Pediatrics suggests that breastfed term infants require 1 mg/kg/day if complementary foods provide insufficient iron after 6 months 5, 4
Preterm or low birthweight infants should receive 2-4 mg/kg/day (maximum 15 mg/day) starting at 1 month of age 5, 4

The World Health Organization recommends continuing iron supplementation for 2 months after hemoglobin normalizes, totaling approximately 3 months of treatment 3, 4
Hemoglobin should be rechecked after 4 weeks of treatment; an increase of ≥1 g/dL confirms iron deficiency anemia and indicates treatment is working 1, 2, 3

The National Institutes of Health suggests adding vitamin C-rich foods (fruits, vegetables, juice) with iron administration to improve absorption 1, 2, 5, 6
Excessive cow's milk consumption (>24 oz or 720 mL daily) should be limited, as it is a leading cause of iron deficiency in this age group 5, 6
Iron-fortified cereals (2+ servings daily) and pureed meats should be introduced after 6 months 2, 5, 6

The Centers for Disease Control and Prevention notes that iron polymaltose complex (Maltofer) is generally dosed equivalently at 3 mg/kg/day for treatment of iron deficiency anemia 1, 2, 3
