If you have atrial fibrillation, a common heart rhythm disorder, your doctor may prescribe anti-arrhythmic medications to help prevent future episodes of atrial fibrillation. Medications may include:
- Dofetilide (Tikosyn)
- Propafenone (Rythmol)
- Amiodarone (Cordarone, Pacerone)
Although these drugs may help maintain a normal heart rhythm, they can cause side effects, including:
Rarely, they may cause ventricular arrhythmias — life-threatening rhythm disturbances originating in the heart's lower chambers. These medications may be needed indefinitely. Even with medications, the chance of another episode of atrial fibrillation is high.
