Multaq(R) is contraindicated in patients with NYHA Class IV heart failure or NYHA Class II-III heart failure with a recent decompensation requiring hospitalization or referral to a specialized heart failure clinic. In a placebo-controlled study in patients with severe heart failure requiring recent hospitalization or referral to a specialized heart failure clinic for worsening symptoms (the ANDROMEDA study), patients given dronedarone had a greater than two-fold increase in mortality. Such patients should not be given dronedarone.
Multaq(R) is also contraindicated in second- or third-degree atrioventricular (AV) block or sick sinus syndrome (except when used in conjunction with a functioning pacemaker), bradycardia <50 bpm, QTc Bazett interval greater than or equal to 500 ms and severe hepatic impairment.
Multaq(R) should not be given to patients who are or may become pregnant (Category X) or nursing.
Multaq(R) should not be coadministered with strong CYP 3A inhibitors or medicinal products that prolong the QT interval.
In patients with new or worsening heart failure, the suspension or discontinuation of Multaq(R) should be considered.
Serum creatinine levels increase by about 0.1mg/dL following Multaq(R) treatment initiation. The elevation has a rapid onset, reaches a plateau after 7 days and is reversible after discontinuation.
Hypokalemia and hypomagnesemia may occur with concomitant administration of potassium-depleting diuretics. Potassium levels should be maintained in the normal range pre and during administration.

About Atrial Fibrillation/Atrial Flutter
Atrial fibrillation is the leading cause of hospitalization for arrhythmia in the U.S. and represents one-third of hospitalizations for arrhythmia in Europe. Hospitalization associated with AF has increased dramatically (two-to-three fold) in recent years in the U.S. Atrial fibrillation is a complex disease that increases the risk of stroke up to five-fold, worsens the prognosis of patients with cardiovascular risk factors, and doubles the risk of mortality. Atrial flutter, another type of arrhythmia generating in the atrium, occurs less frequently, and may evolve into atrial fibrillation.
