Read the Patient Information Leaflet if available from your pharmacist before you start using sotalol and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually 1 to 3 to times a day. You may take it with or without food, but it is important to choose one way and take it the same way with each dose.

If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

The dosage is based on your medical condition and response to treatment. Children's dosage is also based on age and body size.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.

If you use antacids containing aluminum or magnesium, do not take them at the same time as sotalol. These antacids can bind to sotalol and decrease its absorption and effectiveness. Separate doses of these antacids and sotalol by at least 2 hours to reduce this interaction.

Do not take more of this drug than prescribed because you may increase your risk of side effects, including a new serious abnormal heartbeat. Do not take less of this medication or skip doses unless directed by your doctor. Your fast/irregular heartbeat is more likely to return if you do not take sotalol properly. Also, do not run out of this medication. Order your refills several days early to avoid running out of pills.

Tell your doctor if your condition does not improve or if it worsens.
