This medicine is used to treat serious irregular heartbeats. It helps to restore a normal heart rhythm and maintain it. It should be used during pregnancy only if clearly needed and with caution while breastfeeding.

Indications

Flecainide Acetate tablets belong to a group of medicines called anti-arrhythmics. Anti-arrhythmics work by controlling the rate and rhythm of the heart. Flecainide Acetate tablets are 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.

Pharmacology

Flecainide blocks fast inward sodium channels and slowly unbinds during diastole, prolonging the refractory period of the heart. This blockade also shortens the duration of action potentials through the Purkinjie fibers. Flecainide also prevents delayed rectifier potassium channels from opening, lengthening the action potential through ventricular and atrial muscle fibers. Finally, flecainide also blocks ryanodine receptor opening, reducing calcium release from sarcoplasmic reticulum, which reduces depolarization of cells.

Dosage & Administration

Important:
Do not take any medication without a doctor's prescription. Self-medication can be dangerous.
Supraventricular arrhythmias (Irregular heart beat that starts in the upper chambers of your heart): The recommended dose is one 50 mg tablet twice a day. Your doctor may prescribe up to a total dose of 300 mg daily.

Ventricular arrhythmias (Irregular heart beat that starts in the lower chambers of your heart): The recommended dose is 100 mg tablet twice a day. Your doctor may prescribe up to a total dose of 400 mg daily.

For elderly patients, and patients with kidney or heart problems, the doctor may tell you to take a lower dose.
