Product Information

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.

What are the available dosage forms and strengths?



How should you take Dronedarone (Multaq)? 

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use exactly as directed by your healthcare provider.

Dronedarone comes as a 400mg tablet to take by mouth twice a day.

Dronedarone works best if taken around the same time each day; with your morning meal and an evening meal.

Your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG) every 3 months. This will help your doctor determine how long to treat you with dronedarone. Your liver and kidney function may also need to be checked.

Check your own pulse often, and call your doctor right away if you notice an irregular rhythm.

Use dronedarone regularly even if you feel fine or have no symptoms. Get your prescription refilled before you run out of medicine completely.

You should not stop using dronedarone suddenly. Stopping suddenly may make your condition worse.

If you forget to take a dose, skip the missed dose and take the next regularly scheduled dose. Do not use extra medicine to make up the missed dose.

Store at room temperature away from moisture, heat, and light.

Who should not take Dronedarone (Multaq)?

You should not use dronedarone if you are allergic to it, or if:

  • you have severe liver or kidney 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.

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.

What to avoid while taking Dronedarone (Multaq)?

Grapefruit and grapefruit juice may interact with dronedarone and lead to unwanted side effects. Avoid the use of grapefruit products while taking dronedarone.

What should I tell my healthcare provider before using Dronedarone (Multaq)?

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 were recently hospitalized for worsening heart failure symptoms (shortness of breath, chest tightness, night-time breathing problems, swelling, rapid weight gain); or

  • you have a "permanent" atrial fibrillation that cannot be changed back to a normal rhythm (this will be determined by your doctor).

  • other heart problems;

  • an electrolyte imbalance (such as low levels of potassium or magnesium in your blood); or

  • liver or kidney disease.

What are the possible side effects of Dronedarone (Multaq)?

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue. Call your doctor at once if you have:

  • shortness of breath (even with mild exertion), swelling, rapid weight gain;

  • chest pain, wheezing, trouble breathing, dry cough, or coughing up mucus;

  • breathing problems while lying down trying to sleep;

  • severe dizziness, fainting, fast or pounding heartbeats;

  • slow heart rate, feeling like you might pass out;

  • a new or a worsening irregular heartbeat pattern;

  • kidney problems–little or no urination, swelling in your feet or ankles, feeling tired or short of breath; or

  • liver problems–nausea, upper stomach pain, itching, unusual tiredness, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).
