Applies to: Quin-G (quinidine) and Marcaine Spinal (bupivacaine)

Consumer information for this interaction is not currently available.

MONITOR: Amide-type local anesthetics (e.g., lidocaine, bupivacaine, ropivacaine) may have additive cardiac effects when coadministered with class I antiarrhythmic agents. In general, the toxic effects of amide-type anesthetics when coadministered with structurally related antiarrhythmic agents are additive and potentially synergistic which may lead to bradycardia, chest pain, heart block, arrhythmias, ECG abnormalities, and cardiac arrest. The clinical significance of the interaction has not been established.

MANAGEMENT: If coadministration of amide-type local anesthetics with class I antiarrhythmic agents (e.g., procainamide, mexiletine, disopyramide) is required, caution and clinical monitoring are recommended for additive cardiac effects. Advise patients to contact their physician if they experience adverse effects such as chest pain, palpitations, nausea, vomiting, lightheadedness, nervousness, dizziness, or tremors.
