Concomitant use of Vibegron increases digoxin maximal concentrations (Cmax) and systemic exposure as assessed by area under the concentration-time curve (AUC). Serum digoxin concentrations should be monitored before initiating and during therapy with Vibegron and used for titration of the digoxin dose to obtain the desired clinical effect. Continue monitoring digoxin concentrations upon discontinuation of Vibegron and adjust digoxin dose as needed.
