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.
