Toxicity of parenteral iron dextran therapy.

Parenteral iron dextran is efficacious and safe for iron repletion in patients with iron-deficiency anemia. The risk for developing reactions to parenteral iron infusion can be attenuated if patients are carefully selected. Patients with underlying autoimmune disease, malnutrition with indolent infection, and risk for iron overload syndromes should be carefully monitored for complications. Further, the rate of infusion and the route of administration of iron dextran play roles in the risk of adverse reactions. The purpose of this review is to identify and elucidate the mechanisms of the acute and chronic toxicities associated with parenteral iron dextran use.
