Febuxostat — Uses, Dosage, Side Effects & Safety

Drug class: Xanthine oxidase inhibitor (antigout agent)

Overview

Febuxostat is a prescription medication used to lower uric acid levels in adults with gout, a type of arthritis caused by the buildup of uric acid crystals in the joints. It is not used to treat sudden gout attacks, but rather to prevent future flare-ups by keeping uric acid levels under control. Febuxostat works by blocking an enzyme called xanthine oxidase, which is responsible for producing uric acid in the body. By reducing uric acid production, febuxostat helps prevent the formation of painful crystals in the joints and kidneys. Key points for patients: Take febuxostat exactly as prescribed, even if you feel well. It may take several weeks to see the full benefit. Do not use febuxostat to treat an acute gout attack. Let your doctor know if you have a history of heart disease, liver problems, or kidney disease before starting this medication.
