SIDE EFFECTS: Common side effects include dizziness, blurred vision, anorexia, unusual taste, fatigue, nausea and vomiting. Chest pain, heart palpitations, and congestive heart failure may also occur. Because of its beta blocking activity, propafenone must be used with caution in patients with weak heart muscle (congestive heart failure), slow heart rate, any form of heart electrical conduction block, low blood pressure, or asthma. The most serious side effect of propafenone is the causing of serious life- threatening irregular heart rhythms (ventricular arrhythmias or pro-arrhythmia) or heart block. It is for this reason that propafenone is started and doses increased while patients are hospitalized in a monitored setting.
