How Does Nadolol Work?

Nadolol blocks beta-adrenergic receptors, reducing the effects of stress hormones on the heart. This lowers heart rate and helps reduce blood pressure and oxygen demand. It is a nonselective beta blocker, so it also affects beta receptors in the lungs. That property makes it unsuitable for patients with bronchial asthma.

Who Is Treated With Nadolol?

Nadolol is approved for adults with hypertension or chronic angina pectoris. A clinician considers heart rate, blood pressure, kidney function, and other conditions before prescribing it. People with certain slow heart rhythms, significant heart block, cardiogenic shock, or overt heart failure should not take nadolol. Patients with diabetes need to know that beta blockers can mask a rapid heartbeat caused by low blood sugar.

How Is Nadolol Taken?

Nadolol tablets are usually taken once per day, with the dose adjusted for the condition and response. Because the kidneys eliminate much of the drug, people with impaired kidney function may require longer intervals between doses. Take nadolol as prescribed, even when blood pressure symptoms are absent. Do not suddenly stop it without medical guidance.

What Are the Side Effects and Warnings of Nadolol?

Common effects include tiredness, dizziness, a slow pulse, and cold hands or feet. More serious concerns include fainting, worsening heart failure, and difficulty breathing. Nadolol can conceal some warning signs of low blood sugar, particularly a racing heartbeat. Discuss other heart medicines and any planned surgery with the prescriber.

Common Questions About Nadolol

What is nadolol used for?

Nadolol is prescribed to manage high blood pressure and long-term angina. It reduces the heart's workload and helps lower blood pressure.

Does nadolol lower heart rate?

Yes. Nadolol blocks beta receptors that respond to adrenaline, which slows the heart rate. A clinician should evaluate an unusually slow pulse with dizziness or fainting.

Can nadolol be stopped suddenly?

No. Suddenly stopping nadolol can worsen angina and may lead to serious heart problems. A prescriber can recommend a supervised taper.

Is nadolol safe for people with asthma?

Nadolol is contraindicated in people with bronchial asthma because it can narrow the airways. Tell the prescriber about any breathing condition before taking it.
