----------
_ISCHEMIC HEART DISEASE: _ Following abrupt cessation of therapy with
certain beta-blocking agents,
exacerbations of angina pectoris and, in some cases, myocardial
infarction have occurred. When
discontinuing chronically administered metoprolol, particularly in
patients with ischemic heart
disease, the dosage should be gradually reduced over a period of 1 to
2 weeks and the patient
should be carefully monitored. If angina markedly worsens or acute
coronary insufficiency
develops, metoprolol administration should be reinstated promptly, at
least temporarily, and other
measures appropriate for the management of unstable angina should be
taken. Patients should be
warned against interruption or discontinuation of therapy without the
physician’s advice. Because
coronary artery disease is common and may be unrecognized, it may be
prudent not to discontinue
metoprolol therapy abruptly even in patients treated only for
hypertension.
