Following abrupt cessation of certain beta-blocking agents, exacerbations of angina pectoris and, in some cases, myocardial infarction and ventricular arrhythmias have occurred. As with other beta blockers, when discontinuation of atenolol is planned, the patients should be carefully observed and advised to minimize physical activity. If the angina worsens or acute coronary insufficiency develops, promptly reinstitute atenolol, at least temporarily. Warn patients against interruption or discontinuation of therapy without advice of physician .
