Call cardiologist: Your cardiologist should be able to advise you as to how much Tikosyn (dofetilide) to take based on your renal function (GFR) to reduce your risk of serious arrhythmia. This communication between you and your Cardiologist is very important when you are taking a drug that requires close monitoring and supervision.
