Question: how long does it take to get your ferritin levels up?
Answer: Parenteral iron Intravenous infusion results in a rapid replenishment of iron stores with peak ferritin concentrations at 7–9 days after infusion. In our experience the haemoglobin should rise within 2–3 weeks in the majority of patients. There are several intravenous iron preparations available in Australia (Table 5).
