Allopurinol is a prescription medication tablet used for the prevention of kidney or bladder stones. It is also used to prevent increased uric acid levels in pets receiving cancer-related chemotherapy. Allopurinol works by reducing the amount of uric acid made by the body, which can cause gout and kidney problems. Customers may receive this drug under the name Zyloprim.
This medication is formulated for the management of pets with signs and symptoms of primary or secondary gout, pets with leukemia, lymphoma and malignancies who are receiving cancer therapy which causes elevations of serum and urinary uric acid levels. It is also indicated for pets with recurrent calcium oxalate calculi, whose daily uric acid excretion exceeds 800 mg/day in males and 750 mg/day in female pets.
