Interactions between your drugs

Moderate

lidocaine topical carvedilol

Applies to: DermacinRx Lidotral (lidocaine topical) and carvedilol

Consumer information for this interaction is not currently available.

MONITOR: Some beta-blockers may increase lidocaine levels and risk of toxicity. This interaction may also apply to topical formulations of lidocaine. The proposed mechanism is inhibition of CYP450 metabolism and/or decreased cardiac output and hepatic blood flow resulting in decreased hepatic metabolism of lidocaine. In addition, beta-blockers and lidocaine may also have additive negative inotropic effects on the heart. Data have been conflicting and variable. The degree of systemic absorption of topical lidocaine may be dependent on the duration of application and the applied surface area.

MANAGEMENT: Patients receiving concurrent therapy should be monitored for drowsiness, mental status changes, bradycardia, and hypotension. Lidocaine levels should be obtained when clinically necessary. If toxicity is suspected, the lidocaine infusion should be decreased, as possible or the topical formulation of lidocaine should be discontinued.
