Heart Home > Cordarone Loading Dose
As an antiarrhythmia medication, Cordarone® (amiodarone hydrochloride) is prescribed to help treat certain irregular heartbeats called ventricular arrhythmias. It comes in the form of a tablet that is taken once or twice a day.
You will start treatment in a hospital, where a healthcare provider can closely monitor you. The recommended initial dosage of Cordarone for treating ventricular arrhythmias in most adults is usually between 800 mg and 1600 mg a day. This large initial amount of Cordarone is called a loading dose.
Loading doses will continue until the healthcare provider determines that the arrhythmia is adequately controlled. This usually takes one to three weeks. Once the arrhythmia is adequately controlled, the Cordarone dosage will be gradually reduced. Your healthcare provider will try to find the lowest effective maintenance dose that controls your arrhythmia and reduces your risk for side effects.
