Beta blocker overdose


Beta blocker overdose can be life threatening. The three main features include bradycardia, hypotension and hypoglycemia. Hypothermia can occur as well. First degree AV block and second degree AV block type I can occur, however 3rd degree AV block is uncommon.

Treatment includes intravenous fluids to correct hypotension, glucagon to correct hypoglycemia and inotropes such as dobutamine or milrinone to correct bradyarrhythmia.

Charcoal can be used to bind the beta-blocker. Ipecac is contraindicated.
