Corvert FDA Warning


Corvert can cause potentially fatal arrhythmias, particularly sustained polymorphic ventricular tachycardia, usually in association with QT prolongation (torsades de pointes), but sometimes without documented QT prolongation. In registration studies, these arrhythmias, which require cardioversion, occurred in 1.7% of treated patients during, or within a number of hours of, use of Corvert. These arrhythmias can be reversed if treated promptly. It is essential that Corvert be administered in a setting of continuous ECG monitoring and by personnel trained in identification and treatment of acute ventricular arrhythmias, particularly polymorphic ventricular tachycardia. Patients with atrial fibrillation of more than 2 to 3 days' duration must be adequately anticoagulated, generally for at least 2 weeks.


Patients with chronic atrial fibrillation have a strong tendency to revert after conversion to sinus rhythm and treatments to maintain sinus rhythm carry risks. Patients to be treated with Corvert, therefore, should be carefully selected such that the expected benefits of maintaining sinus rhythm outweigh the immediate risks of Corvert, and the risks of maintenance therapy, and are likely to offer an advantage compared with alternative management.
