Potential side effects include nausea, diarrhea, and general weakness.
What Is Multaq?
Multaq® (dronedarone) is a prescription medication approved to treat irregular heart rhythms known as atrial fibrillation or atrial flutter. It is chemically related to amiodarone (an older arrhythmia medication) but is easier to dose and appears to be less likely to cause certain dangerous side effects, compared to amiodarone.

How Does Multaq Work?
It is not yet clear exactly how Multaq works to treat arrhythmias. Most arrhythmia medications are classified using the Vaughn-Williams classification system, which divides arrhythmia medications into four classes depending on how they work. At this point, it seems that Multaq has activity that belongs to all four of the classes.
Effects of Multaq
This medication has been thoroughly studied in various different clinical trials. In general, these studies showed that Multaq was more effective than a placebo (a "sugar pill" with no active ingredients) for preventing heart-related hospitalizations. Some studies also showed that this medication could delay the time until the first recurrence of atrial fibrillation or atrial flutter.
