What is dronedarone?
Dronedarone is a heart rhythm medicine that helps maintain normal heartbeats in certain people with life-threatening rhythm disorders of the atrium (the upper chambers of the heart that allow blood to flow into the heart).
Dronedarone helps lower your risk of needing to be hospitalized for a heart rhythm disorder called atrial fibrillation. Dronedarone is for people who have had this disorder in the past, but now have normal heart rhythm.
Dronedarone may also be used for purposes not listed in this medication guide.
You should not use dronedarone if you have severe liver disease, if you are pregnant or breast-feeding, or if you have ever used amiodarone and then had liver or lung problems. You should not use dronedarone if you have a serious heart condition such as very slow heartbeats, "sick sinus syndrome," or "AV block" (unless you have a pacemaker).
Dronedarone can double your risk of death if you have certain heart conditions. You should not use this medicine if you have severe heart failure, if you were recently hospitalized for worsening heart failure symptoms, or if you have a "permanent" type of atrial fibrillation (this will be determined by your doctor).
Check your pulse often, and tell your doctor right away if you notice an irregular rhythm.
Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact with dronedarone, and some drugs should not be used together.
Dronedarone can cause liver problems. Call your doctor at once if you have symptoms such as nausea, loss of appetite, unusual tiredness, dark urine, or yellowing of your skin or eyes.
Before taking this medicine
You should not use dronedarone if you are allergic to it, or if:
you have severe liver disease;
you have a serious heart condition such as "sick sinus syndrome," "AV block" (unless you have a pacemaker), or very slow heartbeats that have caused you to faint;
you are pregnant or breast-feeding; or
you used a medicine called amiodarone and then had lung problems or liver problems.
Dronedarone is used to treat intermittent or "temporary" heart rhythm disorders. In some people with "permanent" atrial fibrillation, dronedarone increased the risk of stroke, hospitalization, and death. Dronedarone can double your risk of death if you have certain heart conditions. You should not use this medicine if:
you have severe heart failure;
you have a "permanent" atrial fibrillation that cannot be changed back to a normal rhythm (this will be determined by your doctor).
Some medicines can cause unwanted or dangerous effects when used with dronedarone. Your doctor may need to change your treatment plan if you use any of the following drugs:
other heart rhythm medicines;
To make sure dronedarone is safe for you, tell your doctor if you have ever had:
other heart problems;
an electrolyte imbalance (such as low levels of potassium or magnesium in your blood); or
liver or kidney disease.
Do not use dronedarone if you are pregnant. It could harm the unborn baby or cause birth defects. Use effective birth control to prevent pregnancy while you are using this medicine and tell your doctor if you become pregnant.
It is not known whether dronedarone passes into breast milk or if it could harm a nursing baby. You should not breast-feed while taking dronedarone.
