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 sotalol
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.
Before Using sotalol
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For sotalol, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to sotalol or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of sotalol injection in the pediatric population. Safety and efficacy have not been established.
No information is available on the relationship of age to the effects of sotalol injection in elderly patients. However, elderly patients are more likely to have age-related kidney disease, which may require an adjustment in the dose for patients receiving sotalol injection.

Proper Use of sotalol
A nurse or other trained health professional will give you sotalol in a hospital. Sotalol is given through a needle placed in one of your veins.
Tell your doctor or nurse right away if you develop pain or swelling at the site where the needle is placed.
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.
Precautions While Using sotalol
It is very important that your doctor check your progress while you are receiving sotalol to make sure the medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.
Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. These symptoms are more likely to occur when you begin using sotalol, or when the dose is increased. Getting up slowly may help.
Sotalol may cause heart failure in some patients. Check with your doctor right away if you are having chest pain or discomfort; dilated neck veins; extreme fatigue; irregular breathing; an irregular heartbeat; shortness of breath; swelling of the face, fingers, feet, or lower legs; weight gain; or wheezing.

Tell your doctor or nurse right away if you have a rash; itching; hoarseness; trouble breathing; trouble swallowing; or any swelling of your hands, face, or mouth while you are receiving sotalol.
Sotalol may cause changes in your blood sugar levels. Also, sotalol may cover up signs of low blood sugar, such as a rapid pulse rate. Check with your doctor if you have these problems or if you notice a change in the results of your blood or urine sugar tests.
