Increased myocardial depression with any anti-arrhythmic. The dose of flacainide should be halved.AmprenavirAmprenavir possibly increases plasma concentration of Flecainide; increased risk of ventricular arrhythmias. ADVICE: Avoid concomitant use.MajorDisopyramideHalofantrine (HCl)NelfinavirNevirapineParoxetineRitonavirSodium CitrateSodium Citrate may decrease the excretion and increase the serum levels of Flecainide (Acetate), possibly increasing their pharmacologic effects.Verapamil (HCl)VORICONAZOLEAdditive QTc prolongation may occur.
