Camzyos Dosage and Administration
Adult
Swallow whole. Individualize. Initially 5mg once daily; allowable subsequent titration doses are 2.5mg, 5mg, 10mg or 15mg once daily. When initiating or titrating, first consider LVEF then consider the Valsalva LVOT gradient and patient clinical status to guide appropriate dosing; see full labeling. Concomitant with weak CYP2C19 or moderate CYP3A4 inhibitors: initially 5mg once daily (in those who are on stable therapy with a weak CYP2C19 or a moderate CYP3A4 inhibitor). Reduce Camzyos dose by one level (eg, 15mg to 10mg; 10mg to 5mg; or 5mg to 2.5mg) in those who are on Camzyos therapy and intend to initiate a weak CYP2C19 or a moderate CYP3A4 inhibitor; avoid in those who are on a stable treatment with Camzyos 2.5mg, as a lower dose is not available.
