Medications for atrial fibrillation are used to treat irregular heart rhythm. These medications also have other uses, such as controlling high blood pressure, preventing stroke, and easing chest pain. They work by either slowing down your heart rate, preventing blood clots, or restoring normal heart rhythm. Common classes include beta blockers, anticoagulants, and antiarrhythmics. Beta blockers like propranolol (Inderal) are usually taken as oral pills. Anticoagulants, such as warfarin (Coumadin) and apixaban (Eliquis), come in oral forms. Antiarrhythmics like flecainide (Tambocor) and dofetilide (Tikosyn) are also taken orally. Some medications, like digoxin (Lanoxin), are available in both oral and injectable forms. These options help manage your atrial fibrillation in different ways.
