Coreg belongs to the category of beta-blockers, which exert an influence on the cardiovascular system, impacting both the heart and the circulation of blood through arteries and veins.

It is prescribed for the management of heart failure and hypertension, addressing elevated blood pressure.

Additionally, Coreg is employed in cases where a heart attack has resulted in impaired cardiac pumping function.


Do not use Coreg if you have asthma, bronchitis, emphysema, severe liver disease, or a significant heart condition such as heart block, "sick sinus syndrome," or a slow heart rate (unless you have a pacemaker).

Refrain from consuming alcohol within a 2-hour window before or after taking extended-release Coreg CR capsules. Additionally, avoid medications or other products containing alcohol, as it can lead to a rapid release of carvedilol from the controlled-release (CR) capsule into the body.

If you are undergoing treatment for hypertension, continue using Coreg even if you are feeling well. High blood pressure often manifests without noticeable symptoms.

Before taking this medicine

Avoid taking Coreg if you are allergic to carvedilol or if you have:

  • Asthma, bronchitis, emphysema
  • Severe liver disease
  • A serious heart condition, including severe heart failure, heart block, "sick sinus syndrome," or a slow heart rate (unless you have a pacemaker).

To ensure the safety of Coreg for your use, inform your doctor if you have:

  • Coronary artery disease (clogged arteries)
  • History of fainting due to slow heartbeats
  • Fluid retention
  • Lung problems, including asthma
  • Angina (chest pain)
  • Diabetes (as carvedilol may affect your ability to detect low blood sugar)
  • Thyroid disorder
  • Kidney disease
  • Circulation problems, such as Raynaud's syndrome
  • Pheochromocytoma (tumor of the adrenal gland)

Inform your doctor if you are pregnant or breastfeeding. Coreg is not approved for individuals under 18 years old.

Differences Between Coreg and Doxycycline


It is a beta-blocker, specifically a non-selective beta-adrenergic blocker. It is primarily used to treat conditions related to the cardiovascular system, such as heart failure and hypertension.


It is an antibiotic in the tetracycline class. Doxycycline is used to treat various bacterial infections, including respiratory infections, skin infections, and certain sexually transmitted diseases.

Alternative to Coreg

Angiotensin-Converting Enzyme (ACE) Inhibitors:

  • Medications like enalapril, lisinopril, or ramipril are part of the ACE inhibitor class and are often used for heart failure or hypertension.

How should I take Coreg?

Adhere to your doctor's prescription for Coreg precisely. Follow all instructions on the prescription label, and carefully read any accompanying medication guides or instruction sheets. Your doctor may occasionally adjust your dosage.

For optimal effectiveness, take Coreg with food at the same time each day. Swallow the extended-release capsule whole; do not crush, chew, break, or open it.

If you are unable to swallow the capsule whole, you can open it and sprinkle the contents into a spoonful of cold applesauce. Consume the mixture promptly without chewing, and do not save it for later use.

In the event of a switch from tablets to Coreg CR extended-release capsules, your daily total dose may be adjusted. Older adults may experience increased dizziness or faintness during this transition. Adhere to your doctor's guidance.

Regular monitoring of your blood pressure is essential.

Inform your surgeon if you are undergoing surgery, including cataract surgery, and are currently using Coreg. You may need to temporarily discontinue the medication.

Avoid discontinuing Coreg abruptly, as doing so may result in chest pain or a heart attack. Follow your doctor's instructions regarding the gradual reduction of your dosage.

If you are treating high blood pressure, continue using Coreg even if you feel well, as hypertension often presents without symptoms. It may be necessary to use blood pressure medication for the duration of your life.

Remember that Coreg is just one component of a comprehensive treatment plan that may involve diet, exercise, and weight management. Adhere closely to your doctor's instructions.

Store Coreg at room temperature, protecting it from moisture and heat.

What to avoid

Refrain from engaging in driving or activities requiring alertness until you understand the impact of this medication on your reactions, as it may impair your abilities. Additionally, avoid getting up too quickly from a seated or lying position to prevent dizziness.

Coreg side effects

Seek emergency medical assistance if you experience signs of an allergic reaction to Coreg, such as hives, difficulty breathing, or swelling of your face, lips, tongue, or throat.

  • A sensation of light-headedness, as if you might faint.
  • Slow or irregular heartbeats.
  • Cold sensation or numbness in your fingers or toes.
  • Chest pain, persistent dry cough, wheezing, or chest tightness.
  • Symptoms of heart issues, including swelling, rapid weight gain, or difficulty breathing.

  • Dizziness
  • Slow heartbeats
  • Diarrhea
  • Weight gain
  • Dry eyes
  • Difficulties with wearing contact lenses

What other drugs will affect Coreg?

Using certain medications simultaneously may not always be safe. Some drugs can influence the blood levels of other medications, potentially intensifying side effects or reducing the effectiveness of the drugs.

Carvedilol, like any other medication, may interact with other drugs, including both prescription and over-the-counter medicines, as well as vitamins and herbal products. It is crucial to inform your doctor about all the medications you are currently taking and any new ones you start or stop using. This helps ensure a comprehensive understanding of potential interactions and allows your healthcare provider to make informed decisions about your treatment plan.


It is essential to approach the use of Coreg with diligence and adherence to medical guidance. Taking the medication as prescribed, being mindful of potential interactions with other drugs, and promptly addressing any concerning symptoms or side effects contribute to a safer and more effective treatment experience. Always keep an open line of communication with your healthcare provider, informing them of your complete medication history and any changes in your health status.

This proactive approach will enable your medical team to tailor your treatment plan for optimal results while minimizing potential risks. If uncertainties or issues arise, do not hesitate to seek prompt medical attention. Your well-being is paramount, and a collaborative effort with your healthcare provider ensures a more informed and personalized approach to your health.
