How does Corgard work?Nadolol belongs to the class of medications called beta-blockers. It is used for the prevention of symptoms of angina (chest pain) and for the treatment of high blood pressure. When used for the treatment of high blood pressure, it may be used alone or in combination other medications. It works by relaxing blood vessels and reducing the demands on the heart. Your doctor may choose to use a medication for conditions other than the ones listed in these drug information articles. If you're unsure why you are taking this medication, contact your doctor.
How should I use Corgard?The recommended dose of nadolol ranges from 40 mg daily to 320 mg daily in one daily dose, with or without food. For the treatment of angina pectoris or high blood pressure, the recommended starting dose is 80 mg once daily. If the desired response is not achieved after one week, your doctor may increase the daily dose by 80 mg in weekly intervals (e.g., in week 1, the dose is 80 mg; in week 2, the dose is 160 mg; etc.). The maximum recommended daily dose is 240 mg for treatment of angina pectoris and 320 mg for treatment of high blood pressure.

If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
