About Dronedarone
Dronedarone belongs to a group of medications known as 'anti-arrhythmic' primarily used to treat arrhythmia (irregular heartbeat) in patients with paroxysmal (sudden attack) or persistent atrial fibrillation (irregular heartbeat due to poor blood flow). Besides this, Dronedarone is also used to treat 'cardioversion' which is a medical procedure that changes the abnormal heartbeat to a normal rhythm. Arrhythmia is a problem associated with the rate of rhythm at which the heartbeats.
Dronedarone contains 'Dronedarone' a Class III anti-arrhythmic drug that restores normal heart rhythm and reduces heart rate in atrial fibrillation. Dronedarone blocks abnormal electrical signals in the heart. Also, it prevents ventricular fibrillation (a rapid contraction of heart muscle) and ventricular tachycardia (lower chambers of the heart ventricles that beat quickly than normal).
Take Dronedarone as prescribed by your doctor. Your dose and duration of Dronedarone will be advised by your doctor, depending upon your medical condition. In some cases, you may experience slow heartbeat, diarrhoea, nausea and vomiting. Most of these side effects of Dronedarone do not require medical attention and gradually resolve over time.

Patients Concern
Disease/Condition Glossary
Arrhythmia: It is a problem associated with the rate of rhythm at which the heart beats. Generally, in this condition, the heart beats too fast, too slow or with an irregular rate. It can lead to severe heart damage. A cardiac arrhythmia occurs when there are abnormal electrical signals in the heart. When the heart beats too fast, it is known as tachycardia, and if it is too slow, it is called bradycardia. Treatment of arrhythmia includes drugs, medical procedures, implantable devices and sometimes surgery.
FAQs
Dronedarone contains Dronedarone that works as an antiarrhythmic by blocking abnormal electrical signals in the heart. Thus Dronedarone helps to treat the uneven heartbeats and helps in normalising the heart rhythm.
Do not stop using Dronedarone even if you feel better. It should be strictly used as advised by your doctor to avoid the recurrence of symptoms like irregular heartbeat and worsening of the disease.
Dronedarone should be used with caution in cases of any allergic reactions, heart problems like heart failure, slow heartbeat, QT prolongation (heart muscle takes longer than usual to recharge between beats) in the ECG (electrocardiogram), liver, kidney diseases and electrolyte imbalance (low levels of potassium and magnesium).
Store Dronedarone away from direct sunlight and at a temperature not exceeding 30°C. Keep this medicine out of sight and reach of children.
