Typically, for iron replacement therapy, up to 300 mg of elemental iron per day is given, usually as three or four iron tablets each containing 50-65 mg elemental iron given over the course of the day. Ideally, oral iron preparations should be taken on an empty stomach, since foods may inhibit iron absorption. A dose of 200-300 mg of elemental iron per day should result in the absorption of iron up to 50 mgd. Goal of therapy in individuals with IDA is not only to repair anemia, but to provide stores of at least 0.5-1.0 g of iron. Sustained treatment for a period of 6-12 months after correction of the anemia will be necessary to achieve this. Of the complications of oral iron therapy, GI distress is the most prominent and is seen in 15-20 of patients. Typically, reticulocyte count should begin to increase within 4-7 dys after initiation of therapy and peak at IV2 weeks. The amount of iron needed by an individual patient is calculated by the following formula:Body weight kg x 2.3 x 15 - patients hemaglobin, gdL 500 or 100 mg for stores.Also Know:Iron therapy:Dosage-200 mg elemental iron per dayRise of Hb-0.5-1 g per week1st sign of response- Appetite, i fatigue within 12-24 hrs; Reticulocytosis 3-4th DayIndication of Blood transfusion-Hb 7 g or CCFDuration of iron tablets-At least 100 days after correction of HbHb target in various diseases:Thalassemia Hemolytic anemia- 9-10 gMalignancies-- 10-11 gCRT-11-12 g
