Delayed adverse reactions to total-dose intravenous iron polymaltose.

摘要

The rate of infusion reactions to total-dose intravenous iron polymaltose is very low, but the frequency and severity of adverse reactions following the infusion are unknown. In 50 consecutive patients, adverse reactions developed up to 2 days after the infusion in 26% and lasted 1-8 days (median 4). Severe systemic reactions occurred in 8%. Patients should be warned of the chance of delayed reactions and an alternative iron preparation should be considered if parenteral iron is again indicated.
