Terbutaline toxicosis in a dog

Abstract

Terbutaline is a synthetic β2 adrenergic agonist most frequently prescribed in human medicine for the symptomatic relief of asthma. Signs of terbutaline toxicosis result from excessive adrenergic stimulation, and include tremors, prolapse of the nictitating membranes, and tachyarrhythmias. In severe cases of toxicosis, administration of β-adrenergic blocking agents, such as propranolol, will reverse the sympathomimetic effects of terbutaline.
