Persons with congestive heart failure should not take Multaq®. This prescription drug (dronedarone) is prescribed to treat atrial fibrillation or atrial flutter, different types of abnormal heart rhythms.

The label insert of Multaq® carries a black box warning saying patients with severe heart failure should not take Multaq®. This is also true for patients with worsening mild or moderate heart failure that has required recent hospitalization or treatment at a specialized heart failure clinic.

Symptoms of Heart Failure

Heart failure patients are divided into classes of severity defined by the New York Heart Association.

• Class I patients experience no limitation on ordinary physical activity and do not have undue fatigue, palpitations, or shortness of breath.
• A description of Class II heart failure includes slight limitation of physical activity, being comfortable at rest, but ordinary physical activity causes fatigue, heart palpitations, or shortness of breath
• Class III heart failure is characterized by definite limitation of physical activity. Patients are comfortable at rest, but less than ordinary activity causes fatigue, palpitations, and shortness of breath.
• Class IV designates severe heart failure characterized by being unable to perform any physical activity without discomfort and symptoms of cardiac insufficiency while at rest.

A black box warning on the package insert with Multaq® says that a greater than two-fold increase in death was found among classes II, III, and IV heart failure patients who took the medication in a large study.

New or Worsening Heart Failure in Multaq® Patients

Multaq® is contraindicated (should not be taken) in patients with mild to moderate (classes II and III) heart failure who experience new or worsening symptoms and need to be hospitalized or treated at a specialized heart failure clinic. These patients, like patients with Class IV disease, are at greatly increased risk of death if they take Multaq®.

Heart Failure Treatment

If you are diagnosed with heart failure, doctors advise you to take the following precautions:

• Limit salt intake
• Weigh yourself daily and contact your doctor if you gain a significant amount of weight
• Exercise at levels that the doctor recommends
• Take medications prescribed by the doctor
• Visit the doctor frequently
