Iron anaemia and iron-deficient erythropoiesis are treated with oral iron supplements. For chronic haemodialysis or in the case of therapy failure or intolerance to oral iron therapy, intravenous supplements are administered. The costs of iron supplements borne by statutory health care insurance had strongly increased during the observation period from 2006 to 2010. Based on the invoice data of a large health insurance company with a market share of around 18 %, prescription data of iron preparations and laboratory tests were analysed and extrapolated to the Swiss population. During the 5-year observation period, costs of intravenous iron substitution increased by 16.5 m EUR (340.3 %) and the number of individuals treated by 243.5 %. A sharp rise was observed in women of menstruating age, which was mainly due to prescriptions issued by primary care physicians. More than 8 % of intravenous iron substitutions were administered without prior laboratory analysis,and must therefore be regarded as off-label use. A cost-benefit analysis is needed to demonstrate the additional value of intravenous over oral iron supplementation, and intravenous iron supplementation should be administered only to patients with proven iron deficiency.
