Possible symptoms and signs: Headache, anxiety, tremor, nausea, tonic muscle cramps, palpitations, tachycardia and cardiac arrhythmias. A fall in blood pressure sometimes occurs.
Laboratory findings: Hyperglycemia and lactacidosis sometimes occur. β2-agonists may cause hypokalemia as a result of redistribution of potassium.
Treatment of overdosage: Usually no treatment is required. If it can be suspected that significant amounts of terbutaline sulfate have been swallowed, the following measures should be considered: Gastric lavage, activated charcoal. Determine acid-base balance, blood glucose and electrolytes. Monitor heart rate and rhythm and blood pressure. The preferred antidote for overdosage with Terbutaline sulfate (BRICANYL) is a cardioselective beta-receptor blocking agent, but beta-receptor blocking drugs should be used with caution in patients with a history of bronchospasm. If the β2-mediated reduction in peripheral vascular resistance significantly contributes to the fall in blood pressure, a volume expander should be given.
