Efficacy of high-dose intravenous iron in middle-aged to elderly iron-deficient patients.

Iron deficiency (ID) impacts about fifty percent of elderly patients with many symptoms present before iron deficiency anaemia . If left untreated, ID may increase morbidity and mortality. Oral iron is often not tolerated or the absorption is suboptimal. We describe our initial experiences of using high-dose intravenous ferric derisomaltose (Monofer®) infusions of 500 and 1000mg for iron deficiency and iron deficiency anaemia respectively in the outpatient setting. Rapid correction of laboratory parameters and improvement in common symptoms (such as fatigue) were observed. Intravenous iron may be an option for symptomatic iron deficient patients unsuitable for oral iron.
