Hello and thank you for your post on e health forum.
From the history it seems that you have iron deficiency anemia and your doctors have suggested Parenteral iron therapy for correction of the iron defecit.
Iron therapy (Venofer - iron sucrose injection) is used intravenously to replenish body iron stores in patients with iron deficiency anemia.
Iron sucrose is a medication superior to oral iron in achieving a rise in Hb â¥1.0 g/dL and achieving significant high iron stores in the body and is much safer than other parental iron preparations currently in use.
I hope this information here is helpful.
