Information for Patients

Take Lopressor regularly and continuously, as directed, with or immediately following meals.

If a dose should be missed, the patient should take only the next scheduled dose (without doubling it).

Avoid operating automobiles and machinery or engaging in other tasks requiring alertness until the patient’s response to therapy with Lopressor has been determined.

Inform the physician or dentist before any type of surgery that he or she is taking Lopressor.^[1]
