Why is this medication prescribed?

Coreg CR (carvedilol) is a prescription medication primarily used for treating certain heart conditions. Here are the key reasons why Coreg CR might be prescribed and how it should be used:

• Heart Failure: Coreg CR is often prescribed for managing chronic heart failure. It helps improve the heart’s ability to pump blood and reduces the risk of hospitalization and death.
• Hypertension (High Blood Pressure): It is used to lower high blood pressure, which can help prevent strokes, heart attacks, and kidney problems.
• Left Ventricular Dysfunction: After a heart attack, Coreg CR can be prescribed to improve survival and reduce the risk of further heart problems by improving left ventricular function.
• Chronic Stable Angina: It may be used to treat chest pain (angina) and improve exercise tolerance in patients with chronic stable angina.

How should this medicine be used?

Here’s how it is typically used:

• Dosage: The dosage of Coreg CR varies depending on the condition being treated and individual response to the medication. It is usually taken once daily, preferably with food, and should be swallowed whole. The specific dosage should be determined by a healthcare provider based on your medical condition and response to treatment.
• Administration: It’s important not to crush or chew Coreg CR tablets. They should be swallowed whole to ensure the controlled-release mechanism functions correctly. Breaking or chewing the tablet can lead to too much medication being released at once.
• Adjustments: Your doctor may adjust your dosage periodically to achieve the best effect. It’s crucial to follow your doctor’s instructions carefully and not to stop taking the medication without consulting them, even if you feel well.
• Monitoring: While taking Coreg CR, regular monitoring of blood pressure and heart function may be necessary to ensure the medication is working effectively and safely.
• Side Effects: Like all medications, Coreg CR can cause side effects. These may include dizziness, tiredness, diarrhea, and changes in heart rate. If you experience any unusual or severe symptoms, you should contact your healthcare provider.

Always take Coreg CR exactly as prescribed by your doctor and follow their instructions regarding dosage and administration to ensure you get the maximum benefit from the medication while minimizing potential risks.

Other uses for this medicine

• Management of Arrhythmias: Carvedilol may be used to manage certain types of irregular heart rhythms (arrhythmias) by stabilizing the heart’s electrical activity.
• Prevention of Migraine Headaches: There is some evidence suggesting that carvedilol may be effective in preventing migraine headaches, although more research is needed in this area.
• Treatment of Essential Tremor: Carvedilol has been studied for its potential benefit in reducing tremors associated with essential tremor, a neurological disorder causing involuntary shaking.

What special precautions should I follow?

Special precautions should be observed when taking Coreg CR to ensure safe and effective use:

• Dosage and Administration: Take Coreg CR exactly as prescribed by your doctor. Do not adjust your dosage or stop taking the medication without consulting your healthcare provider.
• Blood Pressure Monitoring: Your blood pressure should be monitored regularly while taking Coreg CR, especially at the beginning of treatment and after dosage adjustments. This helps ensure that your blood pressure is well-controlled and does not drop too low.
• Heart Function Monitoring: If you have heart failure, your doctor may monitor your heart function closely using tests such as echocardiograms or other cardiac assessments.
• Avoid Abrupt Discontinuation: Do not suddenly stop taking Coreg CR without your doctor’s guidance, as this can lead to worsening of symptoms or potentially dangerous effects, especially if you have heart disease.
• Risk of Dizziness: Coreg CR can cause dizziness, especially when standing up quickly. To minimize this risk, get up slowly from a sitting or lying position.
• Potential Interactions: Inform your doctor about all other medications, supplements, or herbal products you are taking, as they may interact with Coreg CR. This includes other blood pressure medications, heart medications, and medications that affect liver function.
• Liver Function Monitoring: Since carvedilol is metabolized in the liver, your doctor may periodically check your liver function tests to ensure that the medication is not causing any adverse effects.
• Diabetes Management: Coreg CR can mask signs of low blood sugar (hypoglycemia), particularly in people with diabetes. Monitor your blood sugar levels closely, especially when starting or adjusting the dosage of Coreg CR.

Always follow your doctor’s instructions and guidance regarding the use of Coreg CR to ensure safe and effective treatment, and promptly report any unusual symptoms or side effects.

What special dietary instructions should I follow?

• There are no specific dietary restrictions for Coreg CR. However, maintaining a healthy diet low in sodium and saturated fats can complement the medication’s effectiveness in managing hypertension and heart failure.
• If you have heart failure, your doctor may recommend a diet low in sodium (salt) to help reduce fluid retention and strain on the heart.

What should I do if I forget a dose?

• If you forget to take a dose of Coreg CR, take it as soon as you remember, unless it is almost time for your next scheduled dose. In that case, skip the missed dose and continue with your regular dosing schedule.
• Do not double the dose to catch up.

What side effects can this medication cause?

Coreg CR (carvedilol) can cause a variety of side effects, ranging from mild to potentially serious. It’s important to be aware of these side effects and to notify your doctor if you experience any symptoms that concern you. Common side effects of Coreg CR include:

• Dizziness: This is one of the most common side effects, especially when standing up quickly. It can occur due to the blood pressure-lowering effects of the medication.
• Fatigue: Feeling tired or lethargic is another common side effect of Coreg CR.
• Low Blood Pressure (Hypotension): Coreg CR can lower blood pressure, which may cause symptoms such as dizziness, fainting, or feeling lightheaded.
• Slow Heart Rate (Bradycardia): Carvedilol can decrease your heart rate, which might cause symptoms such as feeling tired, shortness of breath, or fainting.
• Diarrhea: Some people may experience diarrhea as a side effect of Coreg CR.
• Weight Gain: Fluid retention can occur with Coreg CR, leading to weight gain in some individuals.
• Changes in Blood Sugar Levels: Coreg CR can affect blood sugar levels, potentially masking symptoms of low blood sugar (hypoglycemia) in people with diabetes.
• Bronchospasm: If you have asthma or other respiratory conditions, Coreg CR can sometimes cause bronchospasm (constriction of the airways), leading to symptoms such as wheezing or difficulty breathing.
• Depression: Mood changes, including depression, have been reported in some individuals taking Coreg CR.
• Liver Function Changes: In rare cases, Coreg CR may affect liver function, as indicated by elevated liver enzymes in blood tests.
• Allergic Reactions: Although uncommon, allergic reactions to Coreg CR can occur, presenting as rash, itching, swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing.
• Other: Other less common side effects may include sleep disturbances, sexual dysfunction, and blurred vision.

If you experience any severe side effects or any side effects that persist or worsen over time, it’s important to seek medical attention promptly. Your healthcare provider can help manage these side effects and determine whether any adjustments to your treatment plan are necessary.
