In case of overdose the most common effects expected are bradycardia, hypotension, congestive heart failure, bronchospasm and hypoglycaemia.
There is no specific antidote. Treatment must be symptomatic and supportive.
For the management of hypotension the administration of dopamine, dobutamine or norepinephrine is recommended. Atropine should be administered for the management of bradycardia. In case of cute cardiac failure, conventional therapy including digitalis, diuretics and oxygen must be initiated immediately. Bronchospasm may be related with a β2 agonist. Additional therapy with aminophylline may be considered.
