Hello, Thanks for your query. Iron deficiency anemia develops when body stores of iron drop too low to support normal red blood cell (RBC) production. Inadequate dietary iron, iron absorption, bleeding, or loss of body iron in the urine may be the cause. Treatment of iron deficiency anemia consists of: Oral ferrous iron salts are the most economical and effective form Ferrous sulfate is the most commonly used iron salt Better absorption and lower morbidity have been claimed for other iron salts Toxicity is generally proportional to the amount of iron available for absorption Reserve parenteral iron for patients who are either unable to absorb oral iron or who have increasing anemia despite adequate doses of oral iron I do hope that you have found something helpful and I will be glad to answer any further query. Take care
