Sotalol is a beta-blocker that affects the heart and circulation within the atrium and ventricles (the upper and lower chambers of the heart that allow blood to flow into and out of the heart).
Sotalol is used to help keep the heart beating normally in people with certain heart rhythm disorders, such as atrial fibrillation, atrial flutter, ventricular tachycardia, and ventricular fibrillation.
Sotalol may also be used for purposes not listed in this medication guide.
