Propafenone is a class IC antiarrhythmic that slows electrical conduction in the heart. On the FDA-approved human label, it is indicated for certain life-threatening ventricular arrhythmias and some supraventricular arrhythmias.
In veterinary medicine, propafenone has been studied and used off-label in dogs for certain arrhythmias, though it is used less often than other antiarrhythmic options. This information is not a substitute for veterinary diagnosis, prescribing, or monitoring.
This medication is generally started and monitored closely by a veterinary cardiologist or under direct veterinary supervision, often with periodic ECG monitoring. Commonly reported effects include decreased appetite, lethargy, and gastrointestinal upset; it can also worsen certain existing heart rhythm problems, so close monitoring is important. Tell your veterinarian about all other medications your dog is taking, since propafenone has significant drug interactions.
