Uses For Coreg

Carvedilol is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.

Carvedilol is also used to prevent further worsening of congestive heart failure. It is also used to treat left ventricular dysfunction after a heart attack. Left ventricular dysfunction occurs when the left ventricle (the main pumping chamber of the heart) stiffens and enlarges and can cause the lungs to fill with blood.

Carvedilol belongs to a group of medicines called beta-adrenergic blocking agents, beta-blocking agents, or more commonly, beta-blockers. Beta-blockers work by affecting the response to some nerve impulses in certain parts of the body. As a result, they decrease the heart's need for blood and oxygen by reducing its workload. They also help the heart to beat more regularly.

Carvedilol may also be used for other conditions as determined by your doctor.

This medicine is available only with your doctor's prescription.

Other Medical Problems

The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:

  • Angina (severe chest pain) or
  • Bradycardia (slow heartbeat) or
  • Breathing or other lung problems (e.g., bronchitis or emphysema) or
  • Coronary artery disease or
  • Diabetes or
  • Edema (fluid retention or body swelling) or
  • Heart or blood vessel disease or
  • Hyperthyroidism (overactive thyroid) or
  • Hypotension (low blood pressure) or
  • Major surgery, scheduled or
  • Peripheral vascular disease (blood circulation problem) or
  • Pheochromocytoma (adrenal gland tumor)—Use with caution. May make these conditions worse.
  • Asthma or
  • AV block, second or third-degree or
  • Bradycardia (slow heartbeat), severe (without a pacemaker) or
  • Cardiogenic shock (shock caused by heart attack) or
  • Heart failure, decompensated or

Proper Use of carvedilol

This section provides information on the proper use of a number of products that contain carvedilol. It may not be specific to Coreg. Please read with care.

In addition to the use of this medicine, treatment for your high blood pressure may include weight control and changes in the types of foods you eat, especially foods high in sodium (salt).

If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, stroke, or kidney disease.

Precautions While Using Coreg

It is important that your doctor check your progress at regular visits to make sure this medicine is working properly and to allow for changes in the dose.

This medicine may cause dizziness, lightheadedness, or fainting. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.

Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position suddenly. These symptoms are more likely to occur when you begin taking this medicine, or when the dose is increased. Sitting or lying down may help alleviate these unwanted effects.

Before having any kind of surgery (including dental surgery or cataract surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are taking this medicine. A serious eye problem called Intraoperative Floppy Iris Syndrome (IFIS) has occurred in some patients who were taking this medicine or who had recently taken this medicine when they had cataract surgery.

For diabetic patients:

  • This medicine may cause changes in your blood sugar levels. Also, this medicine may cover up signs of hypoglycemia (low blood sugar), such as a rapid pulse rate. Check with your doctor if you have these problems or if you notice a change in the results of your blood or urine sugar tests.

For congestive heart failure patients:

  • Check with your doctor if you have unexplained weight gain or increased shortness of breath. These may be signs of a worsening of your condition.

For patients who wear contact lenses:

  • Carvedilol may cause your eyes to form tears less than they do normally. Check with your doctor if you have dry eyes.

Do not interrupt or stop taking this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping completely. Some conditions may become worse when the medicine is stopped suddenly, which can be dangerous.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
