As an antiarrhythmia medication, amiodarone (Cordarone®, Pacerone®, Nexterone®) is prescribed to help treat certain irregular heartbeats called ventricular arrhythmias. It comes in the form of a tablet and as an injection. Amiodarone injections are given slowly through a tube inserted into the vein (an intravenous, or IV, infusion). The tablets are usually taken by mouth once daily.
Your individual dosage of amiodarone will depend on the severity of your heart arrhythmia, other medications you are taking, and various other factors.
You will start treatment in a hospital, where a healthcare provider can closely monitor you. You will likely need to stay in the hospital for one to three weeks. When receiving amiodarone injections, the initial dosage is about 1000 mg given as a continuous infusion over a 24-hour period. After your arrhythmia is adequately controlled, you will be switched over to amiodarone tablets.
