A 13-month-old with iron deficiency anemia has completed one month of ferrous sulfate therapy. What is the best management now?

• A. Obtain a complete blood count
• B. Continue the medication for another two months
• C. Obtain a serum iron level
• D. Replace with a diet high in iron

Answer: (B)

The main idea here is that treating iron deficiency anemia in a toddler requires continuing iron therapy for several months to replenish iron stores, not just to correct the hemoglobin quickly. After one month of ferrous sulfate, the appropriate step is to keep giving the iron for about two more months, aiming for a total of roughly three months of therapy. Hemoglobin often rises within weeks, but the body's iron stores take longer to rebuild, and completing a full course helps prevent relapse. Choosing to obtain a complete blood count now isn’t the priority because the plan is to continue the existing therapy to finish replenishing stores. Checking a serum iron level isn’t routinely helpful for monitoring response, since iron levels can be unreliable and don’t reflect stores as well as other measures. Replacing with a diet high in iron is supportive but insufficient by itself to correct the deficiency promptly, especially in a growing child. Focus on adherence to the prescribed course, monitor for GI side effects, and recheck clinically and with labs after the full course or as guided by the clinician.
