Descriptions


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. Lowering blood pressure may reduce the risk of stroke and heart attacks.

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.

This medicine is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart.

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

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

This product is available in the following dosage forms:

  • Tablet
  • Capsule, Extended Release

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of carvedilol in the pediatric population. Safety and efficacy have not been established.

Proper Use

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. Your dose may need to be changed several times in order to find out what works best for you.

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). Your doctor will tell you which of these are most important for you. You should check with your doctor before changing your diet.

Many patients who have high blood pressure will not notice any signs of the problem. In fact, many may feel normal. It is very important that you take your medicine exactly as directed and that you keep your appointments with your doctor even if you feel well.

Remember that this medicine will not cure your high blood pressure, but it does help control it. You must continue to take it as directed if you expect to lower your blood pressure and keep it down. You may have to take high blood pressure medicine for the rest of your life. If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, stroke, or kidney disease.

Precautions

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 blood sugar levels. Also, this medicine may cover up the symptoms of low blood sugar (including fast heartbeat) and increase the risk for serious or prolonged hypoglycemia (low blood sugar). Check with your doctor if you notice a change in your normal symptoms or a change in the results of your blood or urine sugar tests. Call your doctor right away if you have anxiety, blurred vision, chills, cold sweats, coma, confusion, cool, pale skin, depression, dizziness, fast heartbeat, headache, increased hunger, nausea, nervousness, nightmares, seizures, shakiness, slurred speech, or unusual tiredness or weakness.

This medicine may worsen the symptoms of heart failure in some patients. Check with your doctor right away if you are having chest pain or discomfort, dilated neck veins, irregular breathing or heartbeat, swelling of the face, fingers, feet, or lower legs, trouble breathing, unusual tiredness or weakness, or weight gain.

For congestive heart failure patients:

  • Check with your doctor if you have unexplained weight gain or increased trouble breathing. 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.
