Flecainide is an antiarrhythmic medication used to prevent and treat certain serious irregular heartbeats (arrhythmias), such as paroxysmal supraventricular tachycardia (PSVT) and life-threatening ventricular arrhythmias. It belongs to the Class IC antiarrhythmic drug class and works by slowing the conduction of electrical impulses in the heart, helping to restore normal heart rhythm.
Used to treat serious irregular heartbeats (arrhythmias) such as PSVT and life-threatening ventricular arrhythmias.
Flecainide can worsen or cause new life-threatening arrhythmias, especially in patients with heart disease. It should only be used in patients with life-threatening arrhythmias who have not responded to other therapies or when other therapies are not tolerated. Careful monitoring is required.
Outcome:
Increased risk of flecainide toxicity
Mechanism:
Amiodarone inhibits flecainide metabolism.

Mechanism:
Additive effects on cardiac conduction.
Outcome:
