About this medicine
Boxed warning
WARNINGS Mortality Flecainide acetate was included in the National Heart Lung and Blood Institute's Cardiac Arrhythmia Suppression Trial (CAST), a long-term, multicenter, randomized, double-blind study in patients with asymptomatic non-life-threatening ventricular arrhythmias who had a myocardial infarction more than six days but less than two years previously. An excessive mortality or non-fatal cardiac arrest rate was seen in patients treated with flecainide acetate compared with that seen in patients assigned to a carefully matched placebo-treated group. This rate was 16/315 (5.1%) for flec
What it is used for
INDICATIONS AND USAGE In patients without structural heart disease, flecainide acetate tablets, USP are indicated for the prevention of — paroxysmal supraventricular tachycardias (PSVT), including atrioventricular nodal reentrant tachycardia, atrioventricular reentrant tachycardia and other supraventricular tachycardias of unspecified mechanism associated with disabling symptoms — paroxysmal atrial fibrillation/flutter (PAF) associated with disabling symptoms Flecainide acetate tablets, USP are also indicated for the prevention of — documented ventricular arrhythmias, such as sustained ventricular tachycardia ( sustained VT), that in the judgment of the physician are life-threatening. Use of flecainide acetate tablets, USP for the treatment of sustained VT, like other antiarrhythmics, should be initiated in the hospital. The use of flecainide acetate tablets, USP are not recommended in patients with less severe ventricular arrhythmias even if the patients are symptomatic. Because of the proarrhythmic effects of flecainide acetate tablets, USP, its use should be reserved for patients in whom, in the opinion of the physician, the benefits of treatment outweigh the risks.

How it is taken
DOSAGE AND ADMINISTRATION For patients with sustained VT, no matter what their cardiac status, flecainide acetate tablets, like other antiarrhythmics, should be initiated in-hospital with rhythm monitoring. Flecainide has a long half-life (12 to 27 hours in patients). Steady-state plasma levels, in patients with normal renal and hepatic function, may not be achieved until the patient has received 3 to 5 days of therapy at a given dose. Therefore, increases in dosage should be made no more frequently than once every four days, since during the first 2 to 3 days of therapy the optimal effect of a given dose may not be achieved. For patients with PSVT and patients with PAF the recommended starting dose is 50 mg every 12 hours. Flecainide acetate tablets doses may be increased in increments of 50 mg bid every four days until efficacy is achieved. For PAF patients, a substantial increase in efficacy without a substantial increase in discontinuations for adverse experiences may be achieved by increasing the flecainide acetate tablets dose from 50 to 100 mg bid. The maximum recommended dose for patients with paroxysmal supraventricular arrhythmias is 300 mg/day. For sustained VT the recom
