# Sotylize (Oral)

Generic name: sotalol (oral route) [ SOE-ta-lol ]
Drug classes: Group III antiarrhythmics, Non-cardioselective beta blockers

Medically reviewed by Drugs.com. Last updated on Apr 28, 2022.

Oral route(Solution)

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)

To minimize the risk of drug-induced arrhythmia, initiate or reinitiate oral sotalol in a facility that can provide cardiac resuscitation and continuous electrocardiographic monitoring. 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 Sotylize

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.

This medicine is available only with your doctor's prescription.

## Before using Sotylize

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 this medicine, the following should be considered:

### Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.

### Pediatric

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.

### Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of sotalol oral solution or Betapace® and Betapace® AF tablets 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 this medicine.

No information is available on the relationship of age to the effects of sotalol tablets in geriatric patients.

### Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
