Flecainide belongs to the group of medicines known as antiarrhythmics. It is used to correct irregular heartbeats to a normal rhythm.
Flecainide produces its helpful effects by slowing nerve impulses in the heart and making the heart tissue less sensitive.
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.
