Allopurinol and iron metabolism in man.

Oral and intravenous ferrokinetic studies were carried out in 9 patients with gout or hyperuricemia to determine the effect of allopurinol on iron absorption, storage, and red cell incorporation. Two studies were carried out in each patient: one during the control period and the other while receiving allopurinol. Allopurinol had no measurable effect on iron metabolism.
