  • Sotalol is used to treat abnormal heart rhythms such as ventricular arrhythmias (for example, ventricular tachycardia) that are life threatening and atrial fibrillation. It is not used for less severe abnormal heart rhythms.
  • Sotalol should not be used in patients with bronchial asthma, sinus bradycardia, second and third degree AV block, unless a functioning pacemaker is present.
  • It also should not be used in people with congenital or acquired long QT syndromes, cardiogenic shock, uncontrolled congestive heart failure, and people who are allergic to sotalol.


Common side effects of sotalol include:

  • shortness of breath,
  • dizziness,
  • fatigue,
  • palpitation,
