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.
Along with its needed effects, sotalol (the active ingredient contained in Betapace) may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
