BRAND® (common name) is contraindicated in patients with known hypersensitivity reactions to mirabegron or any inactive ingredients of the tablet.

BRAND monotherapy or in combination with solifenacin succinate can increase blood pressure in adults. Periodic blood pressure determinations are recommended, especially in hypertensive patients. BRAND is not recommended for use in patients with severe uncontrolled hypertension (defined as systolic blood pressure ≥ 180mm Hg and/or diastolic blood pressure ≥ 110mm Hg).   Worsening of pre-existing hypertension was reported infrequently in patients taking BRAND

Since BRAND is a moderate CYP2D6 inhibitor, the systemic exposure to CYP2D6 substrates is increased when co‐administered with BRAND. Therefore, appropriate monitoring and dose adjustment may be necessary, especially with narrow therapeutic index drugs metabolized by CYP2D6.
