Possible symptoms and signs: headache, anxiety, fine tremor, tonic muscle spasms, palpitations, arrhythmia, nausea, vomiting, cyanosis, tachycardia, mydriasis, breathlessness, coma, respiratory failure.

Occasionally, there may be a decrease in blood pressure.

Overdose treatment:

  • Mild and moderate cases: reduce the dose. Increase the next dose slowly if the bronchospasmolytic effect is insufficient;
  • Severe cases: gastric lavage, activated carbon; determine the basic acid balance, blood glucose and electrolytes; monitor heart rate and rhythm and blood pressure. Metabolic changes should be corrected. The preferred antidote for overdose of Bricanyl Ex is a cardioselective b-blocker (metoprolol). It is recommended for the treatment of arrhythmias with hemodynamic repercussions.


Beta-blocking agents (including eye drops), especially non-selective ones, inhibit the effect of Bricanyl Ex partially or totally.
