Generic Name: nadolol (NAY-doe-lol)
Brand Name: Corgard
Do not suddenly stop taking nadolol. Sharp chest pain, irregular heartbeat, and sometimes heart attack may occur if you suddenly stop nadolol. The risk may be greater if you have certain types of heart disease. Your doctor should slowly lower your dose over several weeks if you need to stop taking it. This should be done even if you only take nadolol for high blood pressure. Heart disease is common and you may not know you have it. Limit physical activity while you are lowering your dose. If new or worsened chest pain or other heart problems occur, contact your doctor right away. You may need to start taking nadolol again.
Nadolol is used for:
Long-term management of angina (chest pain). It is also used alone or with other medicines to treat high blood pressure. It may also be used for other conditions as determined by your doctor.
Nadolol is a beta-blocker. It works by slowing down the heart and decreasing the amount of blood it pumps out. This helps to decrease blood pressure, helps the heart pump more efficiently, and reduces the workload on the heart.
Do NOT use nadolol if:
- you are allergic to any ingredient in nadolol
- you have asthma, uncontrolled heart failure, shock caused by serious heart problems, a very slow heartbeat, or certain types of irregular heartbeat (eg, heart block)
- you are taking mibefradil
Contact your doctor or health care provider right away if any of these apply to you.
