Nadolol is used for:
Long-term management of chest pain or high blood pressure. Nadolol may be used alone or with other high blood pressure medicines. Nadolol may also be used for other conditions as determined by your doctor.
Nadolol is a beta-blocker. Nadolol 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 Corgard
- you have asthma, uncontrolled heart failure, or a very slow and irregular heartbeat (eg, heart block)
- you are taking mibefradil
