What is Lopressor?
Beta- blockers may mask tachycardia occurring with hypoglycemia, but other manifestations such as dizziness and sweating may not be significantly affected. Beta-adrenergic blockade may mask certain clinical signs e. Patients suspected of developing thyrotoxicosis should be managed carefully to avoid abrupt withdrawal of beta-blockade, which might precipitate a thyroid storm. Lopressor also reduces the force of heart muscle contraction and lowers blood pressure.
By reducing the heart rate and the force of muscle contraction, Lopressor reduces heart muscle oxygen demand. Since angina occurs when oxygen demand of the heart exceeds supply,Lopressor is helpful in treating angina. Headache, somnolence, nightmares, and insomnia have also been reported. Respiratory: Wheezing bronchospasm and dyspnea have been reported in about 1 of 100 patients.

What should I avoid while taking Lopressor?
Patients receiving metoprolol before or during surgery involving the use of general anesthetics with negative inotropic effects e. Severe, protracted hypotension and difficulty in restarting the heart have been reported after surgery in patients receiving beta-blockers.
Although, gradual withdrawal of beta-blockers is sometimes recommended prior to general anesthesia to limit the potential for hypotension and heart failure, the manufacturer does not recommend withdrawal of chronically-administered metoprolol prior to major surgery. The risk of precipitating adverse cardiac events e. If beta-blocker therapy is continued, it should be noted that the reduced ability of the heart to respond to beta-adrenergically mediated sympathetic reflex stimuli may augment the risks of general anesthesia and surgical procedures.
Consideration should be given to the type of surgery e. Metoprolol should be used with caution in severe hepatic disease, since drug clearance may be reduced. Since metoprolol is extensively metabolized by the liver, dosage adjustments may be required in patients with hepatic impairment.
