Summary
Nadolol is used to treat high blood pressure, which is hypertension, and chest pain, which is angina. It also helps prevent migraine headaches. These conditions involve issues with blood flow and heart function, and Nadolol helps manage them effectively.
Nadolol works by blocking certain natural chemicals like adrenaline, which affects the heart and blood vessels. This action slows the heart rate and relaxes blood vessels, lowering blood pressure and reducing chest pain. It helps the heart work less hard, improving overall heart health.
The usual starting dose of Nadolol for adults is 40 mg once daily. Your doctor may adjust your dose based on your response and needs. The maximum recommended dose is 320 mg per day. It's taken orally, usually in the morning, with or without food.
Common side effects of Nadolol include fatigue, dizziness, and cold hands or feet. These occur in less than 10% of people. If you notice new symptoms after starting Nadolol, they might be temporary or unrelated to the medication. Always talk with your doctor about any concerns.
Nadolol can cause a slow heart rate, which is bradycardia, and low blood pressure, which is hypotension. It should not be used if you have severe heart conditions or asthma. Always consult your doctor about your medical history before starting Nadolol to ensure it's safe for you.
