Patient Education

Allopurinol


Allopurinol is used to treat gout, high levels of uric acid in the body caused by certain cancer medications, and kidney stones. Allopurinol is in a class of medications called xanthine oxidase inhibitors. It works by reducing the production of uric acid in the body. High levels of uric acid may cause gout attacks or kidney stones. Allopurinol is used to prevent gout attacks, not to treat them once they occur.

Lesinurad


Lesinurad is used in combination with a xanthine oxidase inhibitor to treat hyperuricemia (high levels of uric acid) in people with gout (sudden attacks of redness, swelling, pain, and heat in one or more joints) whose disease is not controlled with their current medication. Lesinurad is in a class of medications called selective uric acid reabsorption inhibitors. It works by helping the kidneys to remove uric acid from the body.
