Multaq Side Effects
Some of the common side effects reported with Multaq include diarrhea, fatigue, and nausea. While most side effects of the drug are mild and do not require medical attention, you should notify your healthcare provider immediately if you experience muscle cramps, fainting, or disorientation.
An Introduction to Multaq Side Effects
As with any medicine, side effects are possible with Multaq® (dronedarone). As with other arrhythmia medications, some of the side effects of Multaq 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.
(This article covers many, but not all, of the possible side effects with Multaq. Your healthcare provider can discuss a more complete list of Multaq side effects with you.)
Common Side Effects of Multaq
Multaq has been studied thoroughly in clinical trials. In some (but not all) of these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people taking a placebo (a "sugar pill" with no active ingredients). This way, it is possible to see what side effects occur, how often they appear, and how they compare to the groups not taking the medicine.
In these studies, the most common Multaq side effects included:
- Diarrhea -- in up to 9 percent of people
- General weakness or fatigue -- up to 7 percent
- Nausea -- up to 5 percent
- Skin reactions (such as rashes, itching, or eczema) -- up to 5 percent
- Abdominal pain (stomach pain) -- up to 4 percent
- A slow heart rate (bradycardia) -- up to 3 percent
- Vomiting -- up to 2 percent
- Indigestion or heartburn -- up to 2 percent.
Some of these common side effects are also dangerous (see the following section for more information about serious side effects of Multaq).
