Objectives: This case series would like to highlight hypophosphatemia related to ferric carboxymaltose and its adverse clinical consequences.
Background: Intravenous iron supplementation is a good alternative to oral iron replacement in iron deficiency anaemia due to its ability to correct iron deficit with minimal infusions without incurring the gastrointestinal side effects of oral iron replacement. Ferric carboxymaltose is one common formula for intravenous iron supplementation.
