Overdosage

No specific information on emergency treatment of overdosage is available for Sectral. However, overdosage with other β-blocking agents has been accompanied by extreme bradycardia, advanced atrioventricular block, intraventricular conduction defects, hypotension, severe congestive heart failure, seizures, and in susceptible patients, bronchospasm and hypoglycemia. Although specific information on the emergency treatment of Sectral overdose is not available, on the basis of the pharmacological actions and the observations in treating overdoses with other β-blockers, the following general measures should be considered:

Empty stomach by emesis or lavage. bradycardia: IV atropine (1 to 3 mg in divided doses). If antivagal response is inadequate, administer isoproterenol cautiously since larger than usual doses of isoproterenol may be required. Persistent hypotension in spite of correction of bradycardia: Administer vasopressor (e.g., epinephrine, levarterenol, dopamine, or dobutamine) with frequent monitoring of blood pressure and pulse rate. Bronchospasm: A theophylline derivative, such as aminophylline and/or parenteral β2-stimulant, such as terbutaline. Cardiac failure: Digitalize the patient and/or administer a diuretic. It has been reported that glucagon is useful in this situation.

Sectral is dialyzable.
