Safety and efficacy of intravenous iron administration for uterine bleeding or postpartum anaemia: a narrative review

The management of iron deficiency anaemia (IDA) consists of oral or intravenous administration of iron supplements. The aim of this narrative review is to summarise information regarding the treatment of IDA in women who have postpartum anaemia or uterine bleeding with intravenous (IV) or oral iron supplements. Fourteen randomised control studies comparing IV to oral iron treatment for IDA in 2913 women with uterine bleeding or postpartum haemorrhage are included. All reviewed studies suggest that IV iron administration is important in treating the IDA in such women and in improving their physical performance and quality of life. Comparisons among intravenous iron supplements show advantages of ferric carboxymaltose over others in time of reaching desired haemoglobin and ferritin values and in adverse reactions. Despite the limitation that the above evidence emerges from not systematically collected data, our review highlights that new forms of IV iron supplements seem safe and efficient in treating IDA.
