Other Comments
Febuxostat may be taken without regard to food or antacid use.
After initiation of febuxostat, an increase in gout flares is frequently observed. This increase is due to a reduction in serum uric acid levels resulting in mobilization of urate from tissue deposits. Febuxostat need not be discontinued due to a flare. Flare prophylaxis with a nonsteroidal anti-inflammatory drug (NSAID) or colchicine is recommended for up to six months upon initiation of febuxostat.
Testing for the target serum uric acid level of less than 6 mg/dL may be performed as early as 2 weeks after initiating febuxostat therapy.
