Sotalol comes as a tablet to take by mouth. Sotalol (Betapace) is usually taken twice a day and sotalol (Betapace AF) is usually taken once or twice a day. Take sotalol consistently, either with food or without food each time. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sotalol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Sotalol controls your condition but does not cure it. Continue to take the medication even if you feel well. Do not stop taking sotalol without talking to your doctor. If sotalol is stopped suddenly, it may cause chest pain or heart attack.
Keep all appointments with your doctor and the laboratory. Your blood pressure should be checked regularly to determine your response to sotalol. Your doctor may ask you to check your pulse (heart rate). Ask your pharmacist or doctor to teach you how to take your pulse. If your pulse is faster or slower than it should be, call your doctor.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
