A Cochrane review of controlled trials comparing [[Intravenous iron infusion|intravenous (IV) iron therapy]] with [[Iron supplement|oral iron]] supplements in people with [[chronic kidney disease]], found low-certainty evidence that people receiving IV-iron treatment were 1.71 times as likely to reach their target [[hemoglobin]] levels. <ref name=":1">{{Cite journal |last=O'Lone |first=Emma L |last2=Hodson |first2=Elisabeth M |last3=Nistor |first3=Ionut |last4=Bolignano |first4=Davide |last5=Webster |first5=Angela C |last6=Craig |first6=Jonathan C |date=2019 |editor-last=Cochrane Kidney and Transplant Group |title=Parenteral versus oral iron therapy for adults and children with chronic kidney disease |url=https://doi.wiley.com/10.1002/14651858.CD007857.pub3 |journal=Cochrane Database of Systematic Reviews |language=en |doi=10.1002/14651858.CD007857.pub3 |pmc=PMC63840966384096 |pmid=30790278}}</ref>Overall, hemoglobin was 0.71g/dl higher than those treated with oral iron supplements. Iron stores in the liver, estimated by serum [[ferritin]], were also 224.84 µg/L higher in those receiving IV-iron. <ref name=":1" />However there was also low-certainty evidence that allergic reactions were more likely following IV-iron therapy. It was unclear whether type of iron therapy administration affects the risk of death from any cause, including cardiovascular, nor whether it may alter the number of people who may require a blood transfusion or dialysis. <ref name=":1" />
 
Soluble iron salts have a significant risk of adverse effects and can cause toxicity due to damage to cellular macromolecules. Delivering iron parenterally has utilised various different molecules to limit this. This has included [[dextrans]], [[sucrose]], carboxymaltose and more recently Isomaltoside 1000.{{citation needed|date=July 2015}}
