In iron-deficiency anemia with initial Hb 8.8 g/dL after iron therapy, an Hb 10.5 g/dL and Hct 36% is observed. What is the next step?

• A. Continue the current dose of ferrous sulfate and recheck labs in 1 to 2 months
• B. Discontinue the supplemental iron and encourage an iron-enriched diet
• C. Increase the ferrous sulfate dose to 4 to 6 mg/kg/day of elemental iron
• D. Refer the child to a pediatric hematologist to further evaluate the anemia

Answer: (A)

The main idea here is that you monitor how the blood counts respond to iron therapy to judge adequacy of treatment. A meaningful rise in hemoglobin after starting iron indicates the body is effectively correcting the iron deficiency, so you continue the current dose and watchful recheck. In this case, hemoglobin increased from 8.8 g/dL to 10.5 g/dL, an improvement of about 1.7 g/dL. That shows a good, expected response to oral iron, so the appropriate next step is to keep the same ferrous sulfate dose and recheck labs in 1–2 months to ensure continued improvement and that iron stores are being replenished. It isn’t necessary to stop iron yet, nor to raise the dose since the response is already adequate. Referral to a hematologist would be reserved for a poor or absent response, relapse after initial improvement, or suspicion of another cause of anemia. If the Hb stop improving or falls again, then reassess adherence, absorption, or consider additional evaluation for other conditions.
