Consumer:Using dofetilide together with mexiletine can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications. In addition, you should let your doctor know if you experience signs of electrolyte disturbance such as weakness, tiredness, drowsiness, confusion, muscle pain, cramps, dizziness, nausea, or vomiting. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:GENERALLY AVOID: Dofetilide should not be used with Class I or other Class III antiarrhythmic agents due to the potential for additive effects on myocardial refractoriness. Many of these agents, including dofetilide, can also cause prolongation of the QT interval, thus concomitant use may increase the risk of ventricular arrhythmias such as ventricular tachycardia and torsade de pointes.
MANAGEMENT: Class I (e.g., disopyramide, quinidine, procainamide) and class III (e.g., amiodarone, ibutilide, sotalol) antiarrhythmic agents should be withheld for at least 3 half-lives before administering dofetilide. In the case of amiodarone with its unpredictable pharmacokinetics, dofetilide should not be initiated until serum amiodarone levels are below 0.3 mcg/mL or amiodarone has been withdrawn for at least three months.
