Dronedarone

Pronounced

"DROE-NE-da-rone"

Common brand names:

Multaq

Uses

This medication is used if you have had certain types of irregular heartbeat (paroxysmal or persistent atrial fibrillation) in the past but now have a normal heart rhythm. It helps you keep a normal heart rhythm and lowers your chance of having to go to the hospital for atrial fibrillation. Dronedarone is known as an antiarrhythmic drug.

This medication should not be used if you have permanent atrial fibrillation because of the increased risk of very serious side effects. See also Warning section.

How to Use This Medication

Read the Medication Guide provided by your pharmacist before you start taking dronedarone and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with food as directed by your doctor, usually twice daily (once with your morning meal and once with your evening meal).

Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. Do not stop taking dronedarone without asking your doctor first. Keep taking this medication even if you feel well. Your doctor may direct you to also take another medication ("blood thinner"/anticoagulant) to lower the risk of getting serious blood clots. Follow your doctor's instructions carefully.

Get medical help right away if your heartbeat or pulse becomes fast or irregular.
