Abstract

Iron deficiency without anaemia is a widespread health problem that often remains undetected. In this context, neurological and psychopathological problems like fatigue and poor concentration are a major issue, but also in Restless-Legs-Syndrome (RLS) iron deficiency is a key element.The exact pathogenesis is often unknown, however, it is known that iron is involved in several very important metabolic processes in the human body. In particular when it comes to fatigue and RLS, it's assumed that reduced activity of tyrosine hydroxylase - a central iron-dependent element of dopamine synthesis - can lead to deficiencies.As part of the therapy, oral iron supplementation is considered to be treatment of choice since it's most cost-effective and well tolerated. Intravenous iron treatment is indicated if primary attempts were not sufficient or not tolerated. To successfully replenish iron storages, about 500-1000 mg are needed. Doses of 200 mg can be administered (iron sucrose) or 1-2 single doses as for ferric carboxymaltose. A check of ferritin-levels not earlier than 8 weeks after last administration is recommended.
