Iron Sucrose Injection USP is a medication used to treat iron deficiency anemia in adults who have chronic kidney disease (CKD) or are undergoing hemodialysis. It delivers elemental iron directly into the bloodstream, where it is transported to the bone marrow and incorporated into hemoglobin. This helps replenish iron stores and stimulates the production of red blood cells, improving symptoms of anemia and increasing hemoglobin levels. Iron Sucrose Injection USP is indicated for the treatment of iron deficiency anemia in adult patients with CKD, including those on dialysis and those not on dialysis.
