To minimize the risk of induced arrhythmia, patients initiated or reinitiated on IV sotalol or converted from IV to oral therapy should be placed in a facility that can provide continuous cardiac monitoring and calculations of creatinine clearance. Do not initiate sotalol therapy if the baseline QTc is longer than 450 milliseconds. If the QT interval prolongs to 500 milliseconds or greater, reduce dose, reduce rate of infusion, or discontinue drug. Adjust dosing interval based on creatinine clearance .
Available Dosage Forms:
Therapeutic Class: Antiarrhythmic, Group III
Pharmacologic Class: Beta-Adrenergic Blocker, Nonselective
Uses For This Medicine
Sotalol injection is used to control rapid heartbeats and abnormal heart rhythms that are serious or life-threatening. The injection may also be used when patients are not able to take the oral form.
Sotalol is a beta-blocker and antiarrhythmic. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and at a regular rhythm.
Sotalol is available only with your doctor's prescription.

Your doctor will give you a few doses of sotalol until your condition improves, and then switch you to an oral medicine that works the same way. If you have any concerns about this, talk to your doctor.
