	| Interactions: |  Amiodarone 
Adverse Effect: hypotension bradycardia or cardiac arrest     Clinical Management: Monitor cardiac function carefully. Amiodarone should be used with caution in patients receiving beta blockers particularly if there is suspicion of underlying dysfunction of the sinus node such as bradycardia or sick sinus syndrome or if there is partial AV block.

Flunarizine 
Adverse Effect: Hypotension bradycardia and AV conduction disturbances     Clinical Management: If concurrent therapy is required monitor cardiac function carefully particularly in patients predisposed to heart failure or bradyarrhythmias.

Adverse Effect: Decreased antihypertensive effect     Clinical Management: If concurrent therapy is required monitor the patients blood pressure carefully and assess the need for a dosage adjustment for the beta blocker. 
Methyldopa 
Adverse Effect: Exaggerated hypertensive response tachycardia or arrhythmias during physiologic stress or exposure to exogenous catecholamines     Clinical Management: Monitor blood pressure carefully during concurrent therapy especially during excessive physiologic stress or use of exogenous catecholamines such as phenylpropanolamine. 
Morphine 
Adverse Effect: Esmolol toxicity (bradycardia hypotension)     Clinical Management: It is suggested that although morphine may elevate steady-state levels of esmolol any subsequent side effects can be titrated by lowering the esmolol infusion rate.
