Several cases of overdosage have been reported, some leading to death.

===Signs and Symptoms===
 
Potential signs and symptoms associated with overdosage with Lopressor are [[bradycardia]], [[hypotension]], [[bronchospasm]], [[myocardial infarction]], [[cardiac failure]] and death.
 
===Management===
 
There is no specific antidote.
 
In general, patients with acute or recent [[myocardial infarction]] may be more hemodynamically unstable than other patients and should be treated accordingly ''(see [[Lopressor warnings and precautions#myocaridal Infarction|WARNINGS, Myocardial Infarction]])''.
 
On the basis of the pharmacologic actions of Lopressor, the following general measures should be employed:
 
'''Elimination of the Drug''': [[Gastric lavage]] should be performed.
 
Other clinical manifestations of overdose should be managed symptomatically based on modern methods of intensive care.
 
'''Hypotension''': Administer a [[vasopressor]], e.g., [[levarterenol]] or [[dopamine]].
 
'''Bronchospasm''': Administer a [[beta2]]-stimulating agent and/or a [[theophylline]] derivative.
 
'''Cardiac Failure''': Administer [[digitalis glycoside]] and [[diuretic]]. In shock resulting from inadequate cardiac contractility, consider administration of [[dobutamine]], [[isoproterenol]] or [[glucagon]].<ref name="dailymed.nlm.nih.gov">{{Cite web  | last =  | first =  | title = LOPRESSOR (METOPROLOL TARTRATE) TABLET [NOVARTIS PHARMACEUTICALS CORPORATION] | url =http://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=bb05420c-fd24-4672-9f62-fdd313819287 | publisher =  | date =  | accessdate = }}</ref>
