Flecainide is used to prevent or treat irregular heartbeats (arrhythmias) such as paroxysmal supraventricular tachycardia (PSVT) and paroxysmal atrial fibrillation/flutter (PAF). Flecainide is also used to prevent life-threatening sustained ventricular tachycardia (sustained VT).
Flecainide belongs to the group of medicines known as antiarrhythmics. It works directly on the heart tissue and will slow the nerve impulses in the heart. This helps keep the heart rhythm normal.
There is a chance that flecainide may cause new or make worse existing heart rhythm problems when it is used. Since it has been shown to cause severe problems in some patients, it is only used to treat serious heart rhythm problems. Discuss this possible effect with your doctor.
This medicine is available only with your doctor's prescription.
