Drug Class and Mechanism
Zyloprim is a xanthine oxidase inhibitor. It works by lowering the body's production of uric acid.
Uric acid is a breakdown product of purines in foods. Uric acid forms crystals in the tissues of the body to cause the inflammation of gout. Elevated blood uric acid levels can also cause kidney disease and stones. Allopurinol can be used to prevent uric acid kidney stones and to prevent recurrent gouty arthritis attacks.
Take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the dose you missed and take only your next regularly scheduled dose. Do not take a double dose of this medication.
