Table of contents:

Multaq generically known as Dronedarone is a prescription drug that is indicated to reduce the risk of hospitalization for atrial fibrillation (AFib). Multaq belongs to a class of drugs called Antidysrhythmics, III. It works by blocking potassium, sodium, and calcium channels and exhibits antiadrenergic properties. It works directly on the heart tissue and slows the nerve impulses in the heart, which helps to maintain normal heart rhythm.

Dronedarone can be indicated in patients with paroxysmal or persistent atrial fibrillation (AF) or atrial flutter (AFL), with a recent episode of AF/AFL and associated cardiovascular risk factors hypertension, diabetes, prior cerebrovascular accident, left atrial diameter, left ventricular ejection fraction, who are in sinus rhythm or who will be cardioverter.

Uses and Dosage

Multaq is available in tablet form to be taken orally with food. You should take it twice daily, following your doctor's instructions. Typically, it is taken once with your morning meal and once with your evening meal. Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

The recommended dosage of MULTAQ for adults is 400 mg twice a day, and it should be taken as one tablet in the morning with breakfast and one tablet in the evening with dinner. Do not stop taking dronedarone without asking your doctor first. Keep taking this medication even if you feel well.
