Multaq, also known as dronedarone, received Food and Drug Administration approval in 2009, notes the FDA. Common side effects are indigestion, diarrhea, nausea and feeling weak. More serious side effects include low potassium; liver failure; altered kidney function; and inflammation, scarring and thickening of lung tissue, explains Multaq.com.

While it can be helpful to some patients, Multaq is not for those with a form of atrial fibrillation known as permanent AFib. Medicine can’t restore the normal heart rhythm of these patients, reports the National Heart, Lung and Blood Institute. Taking Multaq with permanent AFib increases the risk of heart failure, stroke and death. Multaq is not suitable for patients with a type of arrhythmia known as heart block.

About 2.7 million Americans have AFib, according to the American Heart Association. It usually develops among people over 65, with age and heart disease being common causes. Other risk factors for developing the condition include sleep apnea, hyperthyroidism, diabetes, emphysema and blood clots in the lungs, according to Everyday Health.
