Corgard (active ingredient: nadolol) is a prescription beta-blocker used to treat high blood pressure and help prevent angina, or chest pain caused by coronary artery disease.
It works mainly by slowing the heart rate and reducing how hard the heart has to pump.
High Blood Pressure
Corgard is used to treat hypertension, also called high blood pressure.
When blood pressure stays high for a long time, it can place extra strain on the heart and blood vessels. Over time, uncontrolled high blood pressure can increase the risk of serious problems such as heart disease, stroke, and kidney damage.
Corgard helps lower blood pressure by reducing the effects of stress hormones on the heart.
This can help:
High blood pressure often does not cause noticeable symptoms, so you may not feel different even when Corgard is working.
Angina Pectoris
Corgard is also used for the long-term treatment of angina pectoris.
Angina is chest pain or pressure that happens when the heart muscle does not receive enough oxygen-rich blood. It is often caused by narrowing of the coronary arteries.
Symptoms may include:
Corgard helps reduce the amount of oxygen the heart needs by slowing the heart rate and decreasing the force of contraction.
This can help reduce how often angina attacks occur and may allow the heart to work more efficiently.
Corgard is used to help prevent angina over time.
It is not intended to provide rapid relief during a sudden episode of chest pain. A healthcare provider may prescribe a fast-acting medicine, such as nitroglycerin, for sudden angina symptoms.
Corgard belongs to a class of medicines called beta-blockers.
More specifically, nadolol is a nonselective beta-adrenergic blocker.
Blocks the Effects of Adrenaline
The body naturally produces stress hormones such as adrenaline, also called epinephrine.
Adrenaline can make the heart beat faster and harder.
Corgard blocks beta receptors that respond to these hormones. This reduces the effect of adrenaline on the heart.
Slows the Heart Rate
By blocking beta receptors in the heart, Corgard helps slow the heart rate.
A slower heart rate means the heart does not have to work as hard.
This can be helpful for both high blood pressure and angina.
Reduces the Force of the Heartbeat
Corgard also decreases how strongly the heart contracts.
This lowers the heart’s workload and reduces how much oxygen the heart muscle needs.
For people with angina, this can help prevent chest pain during activity or stress.
Helps Lower Blood Pressure
Corgard reduces cardiac output, which is the amount of blood the heart pumps each minute.
It may also reduce the release of renin, a hormone involved in blood pressure regulation.
Together, these effects help lower blood pressure.
Corgard is usually taken regularly rather than only when symptoms occur.
You may not feel an immediate change after starting treatment, especially if you are taking it for high blood pressure.
Your healthcare provider may check:
Your dose may be adjusted based on how well the medication works and whether you develop side effects.
Because Corgard lowers heart rate, some people may develop a heartbeat that is too slow.
Tell your healthcare provider if you experience:
Your dose may need to be reviewed.
Because nadolol slows the heart’s response to exercise, your heart rate may not increase as much as expected during physical activity.
This does not always mean something is wrong, but you should follow your healthcare provider’s advice about exercise and activity levels.
Corgard helps control high blood pressure and angina, but it does not cure coronary artery disease or permanently eliminate hypertension.
Treatment may need to continue for a long period.
Do not stop taking Corgard suddenly without medical advice. Abrupt withdrawal of a beta-blocker can worsen angina and, in some people, may increase the risk of serious heart problems.
Take Corgard exactly as prescribed by your healthcare provider.
Continue taking it even if you feel well, and do not increase, decrease, or suddenly stop your dose without medical guidance.
Corgard is a prescription beta-blocker taken by mouth. It is commonly used to treat high blood pressure and help prevent angina, or chest pain caused by coronary artery disease.
Corgard is usually taken once daily. Your healthcare provider will choose the dose based on your condition, blood pressure, heart rate, kidney function, and response to treatment.
Corgard is generally taken once daily because nadolol stays active in the body for a relatively long period.
Try to take your dose at about the same time every day. Taking it on a regular schedule can help you remember your medication and provide consistent control of your blood pressure or angina symptoms.
Corgard may be taken with or without food.
You can take it with a meal or on an empty stomach. Try to take it in a consistent way each day and follow any specific instructions provided by your healthcare provider.
Take the tablet by mouth with a glass of water.
Follow the instructions provided for your specific tablet. Do not change how you take the medication unless your healthcare provider or pharmacist tells you to do so.
For adults with high blood pressure, a common starting dose is 40 mg once daily.
Your healthcare provider will monitor your blood pressure and may gradually increase the dose if your blood pressure is not adequately controlled.
Many people take 40 mg to 80 mg once daily for hypertension.
Some people may require a higher dose depending on their blood pressure response.
The dose may be increased gradually up to a maximum of 320 mg per day when needed.
Do not increase the dose on your own.
For adults with angina, treatment commonly begins with 40 mg once daily.
Your healthcare provider may increase the dose gradually depending on how often you experience chest pain and how your heart rate responds.
A common maintenance dose for angina is 40 mg to 80 mg once daily.
Some people may require higher doses for adequate symptom control.
The maximum recommended dose for angina is generally 240 mg once daily.
Corgard dosing is individualized.
Your healthcare provider may increase or decrease your dose based on factors such as:
Dose adjustments are usually made carefully because taking too much nadolol can cause the heart rate or blood pressure to become too low.
Nadolol is removed from the body mainly through the kidneys.
If your kidneys do not work normally, the medication may stay in your body longer. Your healthcare provider may adjust how much Corgard you take or increase the amount of time between doses.
Tell your healthcare provider if you have kidney disease or reduced kidney function.
Take Corgard every day as prescribed, even if you feel well.
High blood pressure often causes no noticeable symptoms. Feeling well does not necessarily mean your blood pressure is normal or that you no longer need treatment.
Corgard lowers blood pressure while you are taking it, but it does not permanently cure hypertension.
Continue following other recommendations from your healthcare provider, which may include changes to diet, exercise, weight management, or salt intake.
If you take Corgard for angina, regular treatment can help reduce how often chest pain occurs by lowering the heart’s workload and oxygen demand.
Corgard is used for long-term prevention and is not intended to provide immediate relief during a sudden angina attack.
Follow your healthcare provider’s instructions about what medicine to use if sudden chest pain occurs.
Corgard slows the heart rate as part of its normal action.
Your healthcare provider may recommend checking your pulse during treatment.
Contact your healthcare provider if you develop a very slow heartbeat, severe dizziness, fainting, unusual weakness, or worsening shortness of breath.
If you are using Corgard for hypertension, your healthcare provider may check your blood pressure regularly.
Home blood pressure monitoring may also be recommended.
Keep a record of your readings if instructed and bring them to your medical appointments so your healthcare provider can determine whether your dose needs adjustment.
If you miss a dose of Corgard, take it when you remember unless it is almost time for your next scheduled dose.
If your next dose is close, skip the missed dose and continue with your normal schedule.
Do not take two doses at the same time or take extra medication to make up for a missed dose.
Do not suddenly stop taking Corgard without speaking with your healthcare provider.
Stopping a beta-blocker abruptly can cause your heart rate and blood pressure to increase. In people with coronary artery disease, it may also worsen angina or increase the risk of serious heart problems.
If Corgard needs to be stopped, your healthcare provider may gradually reduce the dose.
Corgard may control your blood pressure or angina so effectively that you no longer notice symptoms.
This does not mean the underlying condition has disappeared.
Continue taking the medication for as long as your healthcare provider recommends.
For high blood pressure and angina, Corgard commonly begins at 40 mg once daily. Many people use maintenance doses of 40 mg to 80 mg once daily, although higher doses may sometimes be required.
The dose may be increased up to 320 mg per day for hypertension or 240 mg per day for angina, depending on the person’s response.
Always take Corgard exactly as prescribed and do not change your dose, frequency, or treatment schedule without first speaking with your healthcare provider.
Corgard (Nadolol) is available in the following forms and strengths:
Alcohol can lower blood pressure and may make side effects such as dizziness or lightheadedness worse while taking Corgard.
Ask your healthcare provider whether alcohol is safe for you during treatment, especially if you already have low blood pressure or dizziness.
Green tea may reduce the amount of nadolol your body absorbs, which could make the medication less effective.
Avoid large or inconsistent amounts of green tea or green tea extracts unless your healthcare provider says they are appropriate. Tell your healthcare provider if green tea is a regular part of your diet.
Do not suddenly stop taking Corgard without speaking with your healthcare provider.
Stopping nadolol abruptly can worsen angina and may lead to serious heart problems, especially in people with coronary artery disease. Your healthcare provider may gradually reduce the dose if treatment needs to be stopped.
Corgard can interact with certain medications, including other medicines that affect blood pressure, heart rate, or breathing.
Tell your healthcare provider about all prescription medicines, over-the-counter products, vitamins, and supplements you take. Do not start or stop another medicine without checking first.
There is not a well-established grapefruit interaction listed for nadolol, so routine grapefruit avoidance is not generally required specifically because of Corgard.
Corgard may cause dizziness, lightheadedness, or tiredness, especially when treatment is started or the dose is increased.
Avoid driving, operating machinery, or performing activities that require full alertness until you know how the medication affects you.
Tell your healthcare provider if you have asthma, emphysema, or another breathing disorder before taking Corgard.
Nadolol is a nonselective beta-blocker and can narrow the airways. Bronchial asthma is listed as a contraindication in the Corgard prescribing information.
Seek medical attention if you develop new or worsening wheezing, shortness of breath, or difficulty breathing.
Tell your healthcare provider if you have diabetes.
Corgard can affect your body’s response to low blood sugar and may hide warning signs such as a fast heartbeat. This can make hypoglycemia more difficult to recognize.
Check your blood sugar as recommended and pay attention to other signs of low blood sugar, such as sweating, hunger, confusion, or weakness.
Tell your healthcare provider if you have or have had heart failure.
Beta-blockers can sometimes worsen heart failure, particularly when treatment is started or adjusted. Your healthcare provider may monitor you for swelling, rapid weight gain, increasing tiredness, or worsening shortness of breath.
Tell your surgeon, dentist, and anesthesiologist that you take Corgard before having surgery or a medical procedure.
Beta-blockers can affect how your heart and blood pressure respond during anesthesia. Do not stop Corgard before surgery unless your healthcare provider specifically tells you to do so.
Skin reactions such as rash may occur in some people taking Corgard.
Tell your healthcare provider if you develop a new or persistent rash or another unusual skin reaction.
Seek urgent medical attention if a rash occurs with facial swelling, difficulty breathing, or other symptoms of a serious allergic reaction.
Talk to your healthcare provider before taking Corgard if you are pregnant, planning to become pregnant, or breastfeeding. Your healthcare provider will consider the potential benefits and risks before deciding whether nadolol is appropriate for you. Nadolol can pass into breast milk, so breastfeeding should also be discussed with your healthcare provider.
Corgard can interact with certain medications. Tell your healthcare provider about all prescription medicines, over-the-counter products, vitamins, and supplements you take before starting treatment. This is especially important for medicines that affect blood pressure, heart rate, blood sugar, or breathing. Your healthcare provider may need to adjust your treatment or monitor you more closely.
If you miss a dose, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time to make up for a missed dose.
No. Do not suddenly stop taking Corgard without speaking with your healthcare provider. Stopping nadolol abruptly may cause your condition to worsen, especially if you have angina or coronary artery disease. Your healthcare provider may gradually reduce your dose if treatment needs to be stopped.
Yes. Corgard can interact with certain medications, so always tell your healthcare provider about everything you take. There is no well-established grapefruit interaction with nadolol, so grapefruit or grapefruit juice does not routinely need to be avoided specifically because of Corgard. However, green tea may reduce nadolol absorption and could make the medication less effective. Ask your healthcare provider or pharmacist about any foods, drinks, medicines, or supplements you regularly use while taking Corgard.
