FDA boxed warning
Exacerbation of Ischemic Heart Disease Following Abrupt Withdrawal -
Hypersensitivity to catecholamines has been observed in patients withdrawn from beta-blocker therapy; exacerbation of angina and, in some cases, myocardial infarction have occurred after
abrupt discontinuation of such therapy. When discontinuing chronically administered nadolol, particularly in patients with ischemic heart disease, the dosage should be gradually reduced over a period of one to two weeks and the patient should be carefully monitored. If angina markedly worsens or acute coronary insufficiency develops, nadolol administration should be reinstituted 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 nadolol therapy abruptly even in patients treated only for hypertension.
About Corgard
Overview
Corgard is a prescription medicine containing nadolol. It comes as tablets taken by mouth. Nadolol is a nonselective beta blocker, meaning it works by blocking beta receptors in the body.
Safety information
Side effects
The label states that most adverse effects were mild and temporary and rarely required treatment to be stopped. This extract does not name common side effects or specify serious reactions that warrant contacting a doctor.

A boxed warning is the strongest warning the US Food and Drug Administration requires on a medicine label. Text is taken from the official label, with internal section references removed.
When to call your doctor
If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.
Before taking this medicine
Do not take Corgard (nadolol) if you have bronchial asthma, a slow heart rate due to sinus bradycardia, heart block greater than first degree, cardiogenic shock, or heart failure with clear signs or symptoms.
Interactions
Nadolol may interact with: • General anesthetics, which may cause a greater fall in blood pressure when used with nadolol. • Diabetes medicines, including insulin and oral medicines. Blood sugar may become too low or too high, and your doctor may need to adjust your diabetes treatment. • Catecholamine-depleting medicines, such as reserpine. Combined effects may cause low blood pressure or an excessively slow heartbeat, with dizziness, fainting or a fall in blood pressure on standing. Close monitoring is needed. • Digitalis glycosides, which also slow the heartbeat and electrical conduction through the heart. Taking them with nadolol increases the risk of a slow heartbeat. Tell your doctor if you have a history of severe allergic reactions. While taking nadolol, you may react more strongly to repeat exposure to allergens, and epinephrine used to treat a severe allergic reaction may not work as expected.
