</p>
Contra Indications
<p>Hypersensitivity reaction to vibegron or any components of product<br />
</p>
Precautions
<p>Urinary retention<br />
Urinary retention reported<br />
Risk increased in patients with bladder outlet obstruction and patients taking muscarinic antagonists medications; closely monitor patients during treatment<br />
Monitor for signs and symptoms of urinary retention<br />
Discontinue in patients who develop urinary retention</p>
<p>Angioedema<br />
Angioedema of the face and/or larynx reported with use; angioedema reported to occur hours after first dose or after multiple doses; angioedema, associated with upper airway swelling, may be life-threatening<br />
If involvement of the tongue, hypopharynx, or larynx occurs, immediately discontinue therapy and provide appropriate therapy and/or measures necessary to ensure a patent airway; therapy is contraindicated in patients with known hypersensitivity to drug or excipients</p>
Pregnancy-Lactation
<p>Pregnancy<br />
No data available on use in pregnant females to evaluate for drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes</p>
<p>Animal data<br />
Delayed fetal skeletal ossification was observed in rabbits at ~898-fold clinical exposure, in presence of maternal toxicity<br />
Developmental toxicity was observed in offspring at ~458-fold clinical exposure, in the presence of maternal toxicity<br />
No effects on offspring at 89-fold clinical exposure</p>
<p>Lactation<br />
No data available on presence in human milk, effects on breastfed infants, or effects on milk production</p>
<p>When a single oral dose of radiolabeled vibegron was administered to postnatal nursing rats, radioactivity was observed in milk</p>
<p>If drug is present in animal milk, it is likely that drug will be present in human milk<br />
</p>
Interactions
<p>Digoxin<br />
Vibegron increases digoxin maximal concentrations and systemic exposure<br />
Monitor serum digoxin concentrations before initiating, during therapy, and for dose titration<br />
Continue monitoring digoxin concentrations after discontinuing vibegron and adjust digoxin dose as needed<br />
</p>

Mechanism of Action
<p>Selective human beta-3 adrenergic receptor agonist<br />
Activation of beta-3 adrenergic receptor increases bladder capacity by relaxing the detrusor smooth muscle during bladder filling</p>
