What is the most important information I should know about nadolol (Corgard)?

Do not stop taking nadolol without first talking to your doctor. Stopping suddenly may make your condition worse.

If you need surgery, tell the surgeon ahead of time that you are using nadolol. You may need to stop using the medicine for a short time.

Nadolol may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Keep using this medicine as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

Nadolol is only part of a complete program of treatment for hypertension that may also include diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely if you are being treated for hypertension.
