TIKOSYN is indicated for the maintenance of normal sinus rhythm in patients with atrial fibrillation/atrial flutter of greater than one week duration who have been converted to normal sinus rhythm.

TYKOSIN is indicated for the conversion of atrial fibrillation/atrial flutter to normal sinus rhythm.

To minimize the risk of induced arrhythmia, patients initiated or re-initiated on TIKOSYN should be placed for a minimum of 3 days in a facility that can provide calculations of creatinine clearance, continuous electrocardiographic monitoring, and cardiac resuscitation. TIKOSYN is available only to hospitals and prescribers who have received appropriate TIKOSYN dosing and treatment initiation education.

TIKOSYN can cause serious ventricular arrhythmias, primarily torsades de pointes type ventricular tachycardia, a polymorphic ventricular tachycardia associated with QT interval prolongation. Calculation of creatinine clearance and QTc for all patients must precede administration of the first dose of TIKOSYN. Renal function and QTc should be re-evaluated every 3 months or as medically warranted.

TIKOSYN is contraindicated in patients with congenital or acquired long QT syndromes, severe renal impairment, or known hypersensitivity to TIKOSYN.

TIKOSYN is also contraindicated with verapamil, hydrochlorothiazide (alone or in combination, such as with triamterene), and cation transport system inhibitors such as cimetidine, ketoconazole, trimethoprim (alone or in combination with sulfamethoxazole), prochlorperazine, and megestrol.

The most common adverse events reported with a frequency of >5% were headache, chest pain, dizziness, respiratory tract infection, dyspnea, and nausea.
