They analyzed the clinical data of about 167,000 older Medicare sufferers who gained IV iron formulations between 2013 and 2018. The formulations incorporated iron dextran, ferumoxytol, ferric gluconate, iron sucrose and ferric carboxymaltose.
All 5 carried an overly low chance of a life-threatening allergy (anaphylaxis), however the very best charges had been for iron dextran (10 sufferers in line with 10,000) and ferumoxytol (4 sufferers in line with 10,000).
“Quantifying the chance of anaphylaxis from present intravenous iron formulations is essential as a result of such a lot is unknown,” mentioned learn about lead creator Chintan Dave, an assistant professor within the Middle for Pharmacoepidemiology and Remedy Science at Rutgers College in New Brunswick, N.J.

‘We conclude via announcing that the charges of anaphylaxis had been very low with all IV iron merchandise, however three- to eightfold larger for iron dextran and ferumoxytol when put next with iron sucrose,” mentioned Dave, who may be a professor on the Ernest Mario Faculty of Pharmacy at Rutgers.
The learn about used to be printed within the magazine Annals of Inside Medication.
The researchers famous that hypersensitive reactions happen extra usally in older sufferers, however it is not transparent why IV iron-boosting formulations on occasion abruptly motive a serious allergy.
Now not handiest that, however “anaphylaxis is simply one of the elements to believe when settling on which IV iron system to manage,” Dave defined. “Those come with now not handiest the chance of anaphylaxis but in addition different elements such because the medical indication, selection of IV iron administrations required, chance of different hostile reactions and value.”
The researchers mentioned there used to be certain information referring to one often-used product.
The findings “supply reassuring knowledge with recognize to the chance of anaphylaxis with ferric carboxymaltose, which has noticed a speedy building up in use following favorable medical trial knowledge in numerous medical indications,” mentioned learn about co-lead creator Dr. Soko Setoguchi, a professor of medication and epidemiology at Rutgers Clinical Faculty and Faculty of Public Well being.
“Via clarifying the chance of this uncommon, however serious hostile response, this data can be utilized to give a contribution to the selection of IV iron arrangements,” she mentioned within the free up.
