The toxic dose depends on the quantity of elemental iron in the preparation, which in turn depends on the iron formulation. While the minimum toxic dose remains controversial, ingestion of more than 40 mg/kg of elemental iron may result in toxicity, while ingestion of more than 60 mg/kg of elemental iron is associated with severe morbidity and possible mortality.
