Zyloprim is used for treating gout. It is used to treat high uric acid levels in the blood or urine caused by certain types of cancer chemotherapy. It is also used to treat certain patients with calcium oxalate kidney stones and high amounts of uric acid in the urine. Zyloprim is a xanthine oxidase inhibitor. It works by lowering the body’s production of uric acid.
