Dronedarone (
Multaq®) 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.
As with any medicine, dronedarone may cause side effects.
As with other arrhythmia medications, some dronedarone side effects can be life-threatening. However, it is expected that this drug may be less likely to cause some serious side effects, compared to similar arrhythmia medications.
Some of the most common side effects include, but are not limited to:
- Diarrhea
- Nausea
- Abdominal pain (stomach pain)
- Vomiting
- General weakness.
