The main function of iron dispersible tablets is to provide the body with iron, which is an important raw material for the synthesis of hemoglobin, therefore, iron dispersible tablets can treat iron deficiency anemia with good effect. The rise in reticulocytes in the blood can begin after one week of oral administration of iron dextran dispersible tablets, and the rise in reticulocytes reaches its peak in 10-14 days. 2-4 weeks later, the hemoglobin increases significantly. Under normal circumstances, taking dextran iron dispersible tablets for 1-3 months can normalize the hemoglobin and will restore the iron storage in the body. After the hemoglobin has returned to normal, it is necessary to reduce the dosage by half and continue taking iron dextran dispersible tablets for 2-3 months.
