Corgard Side Effects

Note: This document contains side effect information about nadolol. Some of the dosage forms listed on this page may not apply to the brand name Corgard.

For the Consumer

Applies to nadolol: oral tablet

Warning

Oral route (Tablet)

Following abrupt cessation of therapy with certain beta-blocking agents, exacerbations of angina pectoris and, in some cases, myocardial infarction have occurred. The dosage should be gradually reduced over a period of 1 to 2 weeks and the patient should be carefully monitored when discontinuing chronic therapy, particularly in patients with ischemic heart disease. If angina markedly worsens or acute coronary insufficiency develops, nadolol 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.

Along with its needed effects, nadolol (the active ingredient contained in Corgard) may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
