The therapeutic equivalence of oral and intravenous iron in renal dialysis patients.

: Oral and intravenous iron were compared in patients treated with renal dialysis by a cross-over trial. Intravenous iron was given over 2 weeks as an iron dextran (equivalent to 100 mg elemental iron). Oral iron was given daily as ferrous sulphate (equivalent to 100 mg elemental iron) in a wax matrix tablet. Each treatment period lasted 26 weeks. There was no significant difference in therapeutic or unwanted effects between the treatments.
