General:
-This drug should not be used to treat asymptomatic hyperuricemia or as monotherapy.

-If gout flares occur during treatment, manage concurrently; discontinuation of this drug should not be necessary.
-This drug is not expected to be effective in patients with severe renal impairment, end stage renal disease, or on dialysis.

Monitoring:
-Serum creatinine levels should be obtained at baseline and periodically during treatment; in patients with CrCl of 45 to less than 60 mL/min or serum creatinine 1.5 to 2 times pretreatment levels, more frequent monitoring is advised.
-Serum creatinine should be promptly assessed in patients reporting signs/symptoms of acute uric acid nephropathy (e.g., acute flank pain, nausea, vomiting).

Patient advice:
-Instruct patients to keep well hydrated while using this drug (e.g., 2 L fluid per day).
-Inform patients that gout flares may occur, and they should not stop taking this drug if a gout flare occurs.
-Patients should be instructed to report signs/symptoms of acute nephropathy to health care provider.
-Patients should be advised to speak to healthcare provider if pregnant, intend to become pregnant, or are breastfeeding; patients using hormonal contraception to prevent pregnancy will need to speak with their health care provider about using a non-hormonal back-up method of birth control during therapy.
