To minimize the risk of induced arrhythmia, patients initiated or reinitiated on oral sotalol or converted from IV sotalol to oral administration should be placed in a facility that can provide cardiac resuscitation, continuous electrocardiographic monitoring and calculations of creatinine clearance. Sotalol can cause life threatening ventricular tachycardia associated with QT interval prolongation. Do not initiate sotalol therapy if the baseline QTc is longer than 450 ms. If the QT interval prolongs to 500 ms or greater, the dose must be reduced, the interval between doses prolonged, or the drug discontinued. Adjust the dosing interval based on creatinine clearance .Oral route(Tablet)

Sotalol can cause life threatening ventricular tachycardia associated with QT interval prolongation. If the QT interval prolongs to 500 msec or greater, reduce the dose, lengthen the dosing interval, or discontinue the drug. Calculate creatinine clearance to determine appropriate dosing .

Uses for sotalol
Sotalol is used to a treat life-threatening heart rhythm problem called ventricular arrhythmia. It is also used to treat heart rhythm problems called atrial fibrillation or atrial flutter.
Sotalol is a beta-blocker. 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 in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of sotalol oral solution in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving sotalol.
No information is available on the relationship of age to the effects of sotalol tablets in geriatric patients.
|All Trimesters||B||Animal studies have revealed no evidence of harm to the fetus, however, there are no adequate studies in pregnant women OR animal studies have shown an adverse effect, but adequate studies in pregnant women have failed to demonstrate a risk to the fetus.|

Proper use of sotalol
Take sotalol only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. When your supply of sotalol is running low, contact your doctor or pharmacist ahead of time. Do not allow yourself to run out of sotalol.
Sotalol should come with a patient information leaflet. Read and follow these instructions carefully. Ask your doctor if you have any questions.
For the first three days, you will receive sotalol in a hospital where your heart rhythm can be monitored.
Measure the oral liquid with a marked measuring spoon, oral syringe, or medicine cup. The average household teaspoon may not hold the right amount of liquid.
If you are also taking an antacid aluminum or magnesium hydroxide, take it 2 hours before or 2 hours after taking sotalol.
Use only the brand of sotalol that your doctor prescribed. Different brands may not work the same way.
The dose of sotalol will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of sotalol. If your dose is different, do not change it unless your doctor tells you to do so.
- For oral dosage forms (solution or tablets):
- For abnormal heart rhythms:
- Adults—At first, 80 milligrams (mg) one or two times a day. Your doctor may adjust your dose every 3 days as needed.
- Children—Use and dose must be determined by your doctor.
- For abnormal heart rhythms:
If you miss a dose of sotalol, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
Precautions while using sotalol
It is very important that your doctor check your progress at regular visits to make sure sotalol is working properly. Blood, urine, and ECG tests will be needed to check for unwanted effects.
Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem such as QT prolongation.
Sotalol may make you dizzy. Do not drive or do anything else that could be dangerous until you know how sotalol affects you. Stand up slowly if you feel dizzy or lightheaded.
Do not interrupt or stop taking sotalol without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely. Some conditions may become worse when the medicine is stopped suddenly, which can be dangerous.
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, swelling of the face, fingers, feet, or lower legs, or weight gain.
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.
Make sure any doctor or dentist who treats you knows that you are using sotalol. Do not stop taking sotalol before surgery without your doctor's approval.
Sotalol may cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor 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 using sotalol.
