Low incidence of adverse events following 90-minute and 3-minute infusions of intravenous iron sucrose in children on erythropoietin.

Aim: To define the adverse events following two different rates and methods of intravenous iron sucrose infusions in children with anaemia due to chronic renal impairment.
