Dosage & Administration

The usual adult dose for oral use is 1 tablet (100 mcg of imidafenacin) twice daily, after breakfast and evening meal. If the efficacy is insufficient, the dose may be increased up to 2 tablets (200mcg) twice daily. Or as prescribed by the physician.

Increase in dosage should be considered when 1 tablet twice daily of imidafenacin provides insufficient efficacy and there are no safety problems. Efficacy and safety have not been established for the initial dose of imidafenacin at 2 tablets twice daily. For patients with moderate to severe hepatic impairment and with severe renal impairment, dosage of imidafenacin should be kept at 1 tablet twice daily.
