In case of overdose, the patient should be monitored for this signs and symptoms such as severe hypotension, bradycardia, heart failure, cardiogenic shock and cardiac arrest. There may also be respiratory problems, bronchospasm, vomiting, disturbed consciousness and generalised seizure. In cases of severe intoxication with shock, supportive treatment must be continued for a sufficiently long period, as a prolongation of elimination half-life and redistribution of carvedilol from deeper compartments are to be expected. The duration of the therapy depends on the severity, therefore supportive treatment should be continued until patient's condition has stabilised.
