Starting flecainide as outpatient gasex

Because there are no adequate and well-controlled studies in pregnant women, Flecainide should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.It is not known whether the use of Flecainide during labor or delivery has immediate or delayed adverse effects on the mother or fetus, affects the duration of labor or delivery, or increases the possibility of forceps delivery or other obstetrical intervention.Results from a multiple dose study conducted in mothers soon after delivery indicates that Flecainide is excreted in human breast milk in concentrations as high as 4 times (with average levels about 2.5 times) corresponding plasma levels; assuming a maternal plasma level at the top of the therapeutic range (1 mcg/mL), the calculated daily dose to a nursing infant (assuming about 700 mL breast milk over 24 hours) would be less than 3 mg.The safety and efficacy of Flecainide in the fetus, infant, or child have not been established in double-blind, randomized, placebo-controlled trials (see Since Flecainide elimination from plasma can be markedly slower in patients with significant hepatic impairment, Flecainide should not be used in such patients unless the potential benefits clearly outweigh the risks. Many patients develop QRS complexes with a duration of 0.12 seconds or more. The primary reason for not being discharged on Ic agent was due to detection of proarrhythmia (n = 15) or ischemia (n = 1) with treadmill testing (5.3%). Since Flecainide elimination is much slower when urine is very alkaline (pH 8 or higher), theoretically, acidification of urine to promote drug excretion may be beneficial in overdose cases with very alkaline urine. The 2A guidelines that are new this year -- as compared to 2001 -- is they now state that in patients with lone afib without structural heart disease, initiation of propafenone or flecainide can be beneficial on an outpatient basis in patients with paroxysmal atrial fibrillation who are in … Of 19 patients in the literature with chronic atrial fibrillation (CAF), 10.5% (2) experienced VT or VF.Flecainide IS NOT RECOMMENDED FOR USE IN PATIENTS WITH CHRONIC ATRIAL FIBRILLATIONCase reports of ventricular proarrhythmic effects in patients treated with Flecainide for atrial fibrillation/flutter have included increased PVCs, VT, ventricular fibrillation (VF) and death.As with other Class 1 agents, patients treated with Flecainide for atrial flutter have been reported with 1:1 atrioventricular conduction due to slowing the atrial rate.

In adolescents (age 12 to 15) the plasma elimination half-life is approximately 11 to 12 hours. Flecainide toxicity can result in increased cardiovascular instability which can significantly alter patient outcome if not recognised early. Flecainide acetate doses may be increased in increments of 50 mg bid every four days until efficacy is achieved. The use of Flecainide is not recommended in patients with less severe ventricular arrhythmias even if the patients are symptomatic.Because of the proarrhythmic effects of Flecainide, its use should be reserved for patients in whom, in the opinion of the physician, the benefits of treatment outweigh the risks.Flecainide should not be used in patients with recent myocardial infarction (see Use of Flecainide in chronic atrial fibrillation has not been adequately studied and is not recommended (see As is the case for other antiarrhythmic agents, there is no evidence from controlled trials that the use of Flecainide favorably affects survival or the incidence of sudden death.Flecainide is contraindicated in patients with preexisting second- or third degree AV block, or with right bundle branch block when associated with a left hemiblock (bifascicular block), unless a pacemaker is present to sustain the cardiac rhythm should complete heart block occur. Atrial fibrillation affects up to 1.5% of the population in the United Kingdom, 1 about 200 000 of whom have recurrent episodes. Conclusions Based on PVC suppression, it appears that plasma levels of 0.2 to 1 mcg/mL may be needed to obtain the maximal therapeutic effect. Treadmill testing is of incremental value and should be completed in all patients after loading Class Ic antiarrhythmic.Peer review under responsibility of Indian Heart Rhythm Society.We use cookies to help provide and enhance our service and tailor content and ads. Ventricular proarrhythmic effects range from an increase in frequency of PVCs to the development of more severe ventricular tachycardia, e.g., tachycardia that is more sustained or more resistant to conversion to sinus rhythm, with potentially fatal consequences. The QRS complex increases on average about 25% (0.02 seconds) and as much as 150% in some patients. The median time-before-recurrence of PAF in patients receiving placebo was about 2 to 3 days, whereas for those receiving Flecainide the median time-before-recurrence was 15 days.In patients without structural heart disease, Flecainide is 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.Use of Flecainide for the treatment of sustained VT, like other antiarrhythmics, should be initiated in the hospital. Flecainide does not undergo any consequential presystemic biotransformation (first-pass effect). Food or antacid do not affect absorption.
