Drug Interaction Report

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with vibegron may increase the plasma concentrations and effects of drugs that are substrates of the P-glycoprotein (P-gp) efflux transporter. The exact mechanism for this interaction has not been established. When a single dose of vibegron (100 mg) was administered to healthy volunteers, the peak plasma concentration (Cmax) and systemic exposure (AUC) of the P-gp substrate digoxin increased by 21% and 11%, respectively. The risk of adverse reactions related to these substrates may be increased.

MANAGEMENT: Caution is advised if vibegron is coadministered with substrates of P-gp, particularly sensitive substrates or those with a narrow therapeutic range. The prescribing information for concomitant medications should be consulted to assess the benefits versus risks of coadministration and for any dosage adjustments that may be required.

Consuming large amounts of certain fruit juices, including grapefruit, orange and apple, may decrease the levels of fexofenadine in your body. Fexofenadine should be taken with water and refrain from drinking large amounts of grapefruit, orange, or apple juice. This will make it easier for your body to absorb the medication.
