An Iron Sucrose injection is offered by us that is given as an infusion into a vein. A healthcare provider will give you this injection. This medicine is sometimes given slowly, and the infusion can take up to 2.5 hours to complete. Iron Sucrose injection is used treat iron-deficiency anemia (a lower than normal number of red blood cells due to too little iron) in people with chronic kidney disease (damage to the kidneys which may worsen over time and may cause the kidneys to stop working).
