Frequently asked questions
How is dronedarone different from amiodarone?
It is related but has fewer thyroid and lung effects. It is also less effective and not suitable for heart failure.
Why are liver tests needed?
Rare cases of severe liver injury have occurred, so blood tests are done, especially early on.
Can I take it if my AF is permanent?
No. It is used to keep normal rhythm, not for permanent AF.
