Nadolol (NAY-doe-lol)Brand Name:
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 chest pain or high blood pressure. It may be used alone or with other high blood pressure medicines. It may also be used for other conditions as determined by your doctor.
Nadolol is a beta-blocker. It works by interfering with certain body chemicals, which causes the heart to beat with less force and pump out less blood. This allows the heart to beat more slowly and regularly. By blocking these chemicals, blood vessels are relaxed and widened, allowing blood pressure to decrease.
Do NOT use Nadolol if:
- you are allergic to any ingredient in Nadolol
- you have asthma, uncontrolled heart failure, or a very slow and 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.
