General supportive measures and symptomatic treatment should be initiated in cases of suspected overdose.
An overdose will likely produce signs, symptoms or adverse effects associated with the pharmacological actions of the individual components (e.g. tachycardia, tremor, palpitations, headache, nausea, vomiting, drowsiness, ventricular arrhythmias, metabolic acidosis, hypokalaemia, hyperglycaemia, suppression of hypothalamic pituitary adrenal axis function).
Use of cardioselective beta blockers may be considered for treating beta2-adrenergic effects, but only under the supervision of a physician and with extreme caution, since the use of beta2-adrenergic blockers may provoke bronchospasm. In serious cases, patients should be hospitalised.
