Flenide tablets contain the active substance flecainide acetate, which belongs to a group of medicines called anti-arrhythmics. Anti-arrhythmics work by controlling the rate and rhythm of the heart.
Flenide is used to treat:
• Arrhythmias (irregular heart beat)
• Tachycardia (heart beating too fast)
• Atrial fibrillation (rapid contractions of muscles in the heart).
It is important for your doctor to treat these conditions quickly and effectively in order to prevent more serious heart problems from developing.
