Overdosage may lead to severe bradycardia and to conduction disturbances with the appearance of an idioventricular rhythm, particularly in elderly patients or during digitalis therapy. In these circumstances, Amiodarone therapy should be withdrawn. Gastric lavage may be employed to reduce absorption, in addition to general supportive measures. Patients should be monitored and if bradycardia ensues, beta adrenostimulants or glucagon may be given. Spontaneously resolving attacks of ventricular tachycardia may also occur. Due to the pharmacokinetics of Amiodarone, adequate and prolonged surveillance of the patient, particularly cardiac status, is recommended.
