What is sotalol?
Sotalol is in a group of drugs called beta-blockers. Beta-blockers affect the heart and circulation (blood flow through arteries and veins).
Sotalol is used to help keep the heart beating normally in people with certain heart rhythm disorders of the ventricles (the lower chambers of the heart that allow blood to flow out of the heart). Sotalol is used in people with ventricular tachycardia or ventricular fibrillation.
Another form of this medicine, called Sotalol AF, is used to treat heart rhythm disorders of the atrium (the upper chambers of the heart that allow blood to flow into the heart). Sotalol AF is used in people with atrial fibrillation or atrial flutter. Sotalol (Betapace and Sorine) is not used for the same conditions that sotalol AF (Betapace AF) is used for.
Sotalol may also be used for purposes other than those listed in this medication guide.
Do not use this medication if you are allergic to sotalol, or if you have:
- certain heart conditions, especially "AV block" (unless you have a pacemaker);
- a history of "Long QT syndrome"; or
- severe or uncontrolled congestive heart failure.
Before using sotalol, tell your doctor if you are allergic to any drugs, or if you have:
- breathing problems such as bronchitis or emphysema;
- a history of heart disease or congestive heart failure;
- kidney disease;
- a thyroid disorder;
- an electrolyte imbalance such as low levels of potassium or magnesium in your blood; or
- if you have recently had a heart attack.
If you have any of these conditions, you may not be able to use sotalol, or you may need a dosage adjustment or special tests during treatment.
FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
Sotalol can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Do not take an antacid within 2 hours before or after taking sotalol. Avoid using antacids without your doctor’s advice. Use only the specific type of antacid your doctor recommends. Antacids contain different medicines and some types can make it harder for your body to absorb sotalol.
