Interactions

7 DRUG INTERACTIONS Concomitant use of GEMTESA increases digoxin maximal concentrations (C max ) and systemic exposure as assessed by area under the concentration-time curve (AUC) [see Clinical Pharmacology ( 12.3 )] . Serum digoxin concentrations should be monitored before initiating and during therapy with GEMTESA and used for titration of the digoxin dose to obtain the desired clinical effect. Continue monitoring digoxin concentrations upon discontinuation of GEMTESA and adjust digoxin dose as needed. Digoxin : Measure serum digoxin concentrations before initiating GEMTESA. Monitor serum digoxin concentrations to titrate digoxin dose to desired clinical effect. ( 7 )

Warnings

5 WARNINGS AND PRECAUTIONS Urinary Retention : Monitor for urinary retention, especially in patients with bladder outlet obstruction and also in patients taking muscarinic antagonist medications for OAB, in whom the risk of urinary retention may be greater. If urinary retention develops, discontinue GEMTESA. ( 5.1 ) Angioedema : Angioedema of the face and/or larynx has been reported with GEMTESA. ( 5.2 ) 5.1 Urinary Retention Urinary retention has been reported in patients taking GEMTESA. The risk of urinary retention may be increased in patients with bladder outlet obstruction and also in patients taking muscarinic antagonist medications for the treatment of OAB. 4 CONTRAINDICATIONS GEMTESA is contraindicated in patients with known hypersensitivity to vibegron or any components of GEMTESA.
