Generic Name: Nadolol (nay-DOE-lahl)
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 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 the
certain body chemicals, which cause 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 or a serious heart problem, including
a blockage, heart attack, heart failure, very slow heartbeat,
or low blood pressure |
| • |
you are currently taking indomethacin or one of its
derivatives, mibefradil, stimulants (eg, epinephrine),
or a theophylline |
| |
|
Contact
your doctor or health care provider right away if any
of these apply to you. |

products that contain stimulants. These products may include
diet pills or cold medicines. Contact your doctor if you
have any questions or concerns. |

chills, or tremors; or make you more hungry. Check blood
sugar levels closely. Ask your doctor before you change
the dose of your diabetes medicine. |
| • |
