What is nadolol?
Nadolol is a beta-blocker that affects the heart and circulation (blood flow through arteries and veins).
Nadolol may also be used for other purposes not listed in this medication guide.
Before taking this medicine
You should not use nadolol if you are allergic to it, or if you have:
a serious heart condition such as "AV block" (2nd or 3rd degree) or severe heart failure; or
if your heart cannot pump blood properly.
To make sure nadolol is safe for you, tell your doctor if you have:
coronary artery disease (clogged arteries);
congestive heart failure;
a thyroid disorder;
diabetes (taking nadolol can make it harder for you to tell when you have low blood sugar); or
a history of allergies.
It is not known whether nadolol will harm an unborn baby. Nadolol may cause heart or lung problems in a newborn if the mother takes the medicine during pregnancy. Tell your doctor if you are pregnant or plan to become pregnant while using nadolol.
Nadolol can pass into breast milk and may harm a nursing baby. You should not breast-feed while taking nadolol.
How should I take nadolol?
Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use nadolol in larger or smaller amounts or for longer than recommended.
Nadolol is usually taken once per day. Follow your doctor's dosing instructions very carefully.
Do not skip doses or stop using nadolol suddenly. Stopping suddenly may make your condition worse. Follow your doctor's instructions about tapering your dose.
Your blood pressure will need to be checked often.
This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using nadolol.
If you need surgery, tell the surgeon ahead of time that you are using nadolol.
If you are being treated for high blood pressure, keep using this medicine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine 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.
Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if your next dose is less than 8 hours away. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking nadolol?
nadolol may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Drinking alcohol can further lower your blood pressure and may increase certain side effects of nadolol.

Call your doctor at once if you have:
a light-headed feeling, like you might pass out;
