Adverse Reactions
Clinical Trials Experience: Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
A total of 2757 subjects with hyperuricemia and gout were treated with Febuxostat 40 mg or 80 mg daily in clinical studies. For Febuxostat 40 mg, 559 patients were treated for ≥ 6 months. For Febuxostat 80 mg, 1377 subjects were treated for ≥ 6 months, 674 patients were treated for ≥ 1 year and 515 patients were treated for ≥ 2 years.
Most Common Adverse Reactions: In three randomized, controlled clinical studies (Studies 1, 2 and 3), which were 6 to 12 months in duration, the following adverse reactions were reported by the treating physician as related to study drug. Table summarizes adverse reactions reported at a rate of at least 1% in Febuxostat treatment groups and at least 0.5% greater than placebo. (See table.)

The most common adverse reaction leading to discontinuation from therapy was liver function abnormalities in 1.8% of Febuxostat 40 mg, 1.2% of Febuxostat 80 mg, and in 0.9% of allopurinol-treated subjects.
In addition to the adverse reactions presented in Table, dizziness was reported in more than 1% of Febuxostat-treated subjects although not at a rate more than 0.5% greater than placebo.
Less Common Adverse Reactions: In phase 2 and 3 clinical studies the following adverse reactions occurred in less than 1% of subjects and in more than one subject treated with doses ranging from 40 mg to 240 mg of Febuxostat. This list also includes adverse reactions (less than 1% of subjects) associated with organ systems from Precautions.

Cardiovascular Safety: Cardiovascular events and deaths were adjudicated to one of the pre-defined endpoints from the Anti-Platelet Trialists' Collaborations (APTC) (cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke) in the randomized controlled and long-term extension studies. In the Phase 3 randomized controlled studies, the incidences of adjudicated APTC events per 100 patient-years of exposure were: Placebo 0 (95% Cl 0.00-6.16), Febuxostat 40 mg 0 (95% Cl 0.00-1.08), Febuxostat 80 mg 1.09 (95% Cl 0.44-2.24), and allopurinol 0.60 (95% Cl 0.16-1.53).
In the long-term extension studies, the incidences of adjudicated APTC events were: Febuxostat 80 mg 0.97 (95% Cl 0.57-1.56), and allopurinol 0.58 (95% Cl 0.02-3.24).
Overall, a higher rate of APTC events was observed in Febuxostat than in allopurinol-treated patients. A causal relationship with Febuxostat has not been established. Monitor for signs and symptoms of MI and stroke.
