Response to iron therapy can be seen in an increase in reticulocyte count 5-10 days after the initiation of iron therapy, with the hemoglobin level increasing by about 1 g/dL weekly until normal values are restored.
The usual benchmark for successful iron supplementation is a 2-g/dL increase in the hemoglobin level in 3 weeks. However, a meta-analysis suggested that in patients receiving oral iron supplementation, a hemoglobin measurement after 2 weeks that shows an increase of 1.0 g/dL or more over baseline actually predicts a longer term and sustained response to continued oral iron therapy.
