Product / population
Adult oral BPH product.
Renal measure
Not specified; verify before use
Adult regimen

Start 0.4 mg once daily, about 30 minutes after the same meal each day. If the response is inadequate after 2-4 weeks, 0.8 mg daily may be used. After an interruption of several days, restart at 0.4 mg daily. Swallow capsules intact.

Renal statement and uncertainty

The label requires no renal dose adjustment. End-stage disease with creatinine clearance <10 mL/min/1.73 m2 was not studied. A separate dialysis regimen is not established by that statement.
