Carvedilol is used for:

Treating high blood pressure or certain types of heart failure. It may also be used after a heart attack to improve survival in certain patients. It may be used along with other medicines. It may also be used for other conditions as determined by your doctor.

Carvedilol is a beta-blocker. It works by relaxing the blood vessels, slowing down the heart, and decreasing the amount of blood it pumps out. This decreases blood pressure, helps the heart pump more efficiently, and reduces the workload on the heart.

Do NOT use Carvedilol if:

• you are allergic to any ingredient in Carvedilol
• you have moderate to severe heart block, sick sinus syndrome, very slow heartbeat (unless you have a permanent pacemaker), certain types of irregular heartbeat or severe heart failure, or shock caused by serious heart problems
• you have asthma or other severe breathing problems
• you have severe liver problems
• you are taking mibefradil

Contact your doctor or health care provider right away if any of these apply to you.

Important safety information:

• Carvedilol may cause dizziness, fainting, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use Carvedilol with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
• Carvedilol may cause dizziness, lightheadedness, or fainting. These effects may occur within the first hour after you take your dose. They may be more likely when you start taking Carvedilol or if your dose is increased. Alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects. Tell your doctor if these effects occur.
• Do NOT take more than the recommended dose without checking with your doctor.
• Do not suddenly stop taking Carvedilol. Sharp chest pain, irregular heartbeat, and sometimes heart attack may occur if you suddenly stop Carvedilol. The risk may be greater if you have certain types of heart disease. Your doctor should slowly lower your dose over several weeks if you need to stop taking it. This should be done even if you only take Carvedilol for high blood pressure. Heart disease is common and you may not know you have it. Limit physical activity while you are lowering your dose. If new or worsened chest pain or other heart problems occur, contact your doctor right away. You may need to start taking Carvedilol again.
• Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel "normal." Tell your doctor if you develop any new symptoms.
• Tell your doctor or dentist that you take Carvedilol before you receive any medical or dental care, emergency care, or surgery.
• If you have a history of any severe allergic reaction, talk with your doctor. You may be at risk for an even more severe allergic reaction if you come into contact with the substance that caused your allergy. Some medicines used to treat severe allergies may also not work as well while you are using Carvedilol .
• Diabetes patients - Carvedilol may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
• Diabetes patients - Carvedilol may hide signs of low blood sugar, such as a rapid heartbeat. Be sure to watch for other signs of low blood sugar. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your vision change; give you a headache, chills, or tremors; or make you more hungry. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
• Lab tests, including blood pressure and heart function, may be performed while you use Carvedilol. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
• Use Carvedilol with caution in the ELDERLY; they may be more sensitive to its effects, especially dizziness.
• Carvedilol should be used with extreme caution in CHILDREN younger than 18 years old; safety and effectiveness in these children have not been confirmed.

Other Useful Information:

Calcium: A mineral found mainly in the hard part of bones, where it is stored. Calcium is added to bones by cells called osteoblasts and is removed from bones by cells called osteoclasts. Calcium is essential for healthy bones. It is also important for muscle contraction, heart action, nervous system maintenance, and normal blood clotting. Food sources of calcium include dairy foods, some leafy green vegetables such as broccoli and collards, canned salmon, clams, oysters, calcium-fortified foods, and tofu. According to the National Academy of Sciences, adequate intake of calcium is 1,200 milligrams a day (four glasses of milk) for men and women 51 and older, 1,000 milligrams a day for adults 19 through 50, and 1,300 milligrams a day for children 9 through 18. The upper limit for calcium intake is 2.5 grams daily.

Cavities: Holes in the two outer layers of a tooth called the enamel and the dentin. The enamel is the outermost white hard surface and the dentin is the yellow layer just beneath enamel. Both layers serve to protect the inner living tooth tissue called the pulp, where blood vessels and nerves reside. Small cavities may not cause pain, and may be unnoticed by the patient. Larger cavities can collect food, and the inner pulp of the affected tooth can become irritated by bacterial toxins, foods that are cold, hot, sour, or sweet - causing toothache.

Naturopathy: A system of therapy based on preventative care, and on the use of heat, water, light, air, and massage as primary therapies for disease. Some naturopaths use no medications, either pharmaceutical or herbal. Some recommend herbal remedies only. A few who are licensed to prescribe may recommend pharmaceuticals in those cases where they feel their use is warranted.

Naturopathy is an American healthcare profession. It was founded in the US as a formal healthcare system at the turn of the 20th century by medical practitioners from various natural therapeutic disciplines. By the early 1900s, more than 20 naturopathic medical schools existed, and naturopathic physicians were licensed in most States. Today there are more than 1,000 licensed naturopathic doctors in the US.

As practiced today, naturopathic medicine integrates traditional natural therapeutics -- including botanical medicine, clinical nutrition, homeopathy, acupuncture, traditional oriental medicine, hydrotherapy, and naturopathic manipulative therapy -- with modern scientific medical diagnostic science and standards of care. The medical research base of naturopathic practice consists of empirical documentation of treatments using case history observations, medical records, and summaries of practitioners' clinical experiences.

At present, the two accredited naturopathic medical schools in the US have active research departments. Naturopathic researchers have investigated the pharmacology and physiological effects of nutritional and natural therapeutic agents, and naturopathic physicians have been active in the investigation of new homeopathic remedies and in the natural treatment of women's health problems. The most recently completed naturopathic study in women's health tested the clinical and endocrine effects of a botanical formula as an alternative to estrogen replacement therapy.

Blood: The familiar red fluid in the body that contains white and red blood cells, platelets, proteins, and other elements. The blood is transported throughout the body by the circulatory system. Blood functions in two directions: arterial and venous. Arterial blood is the means by which oxygen and nutrients are transported to tissues while venous blood is the means by which carbon dioxide and metabolic by-products are transported to the lungs and kidneys, respectively, for removal from the body.

Blood pressure: The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. It's measurement is recorded by two numbers. The first (systolic pressure) is measured after the heart contracts and is highest. The second (diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called "hypertension".

Brain: That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called "hemispheres."

Disease: Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.

Doctor: In a medical context, any medical professional with an MD, a PhD, or any other doctoral degree. The term doctor is quite nonspecific. A doctor may, for example, be a physician, psychologist, biomedical scientist, dentist, or veterinarian. In a nonmedical context, a professor of history might be addressed as doctor, an eminent theologian might be named a doctor of a church, and a person awarded an honorary doctorate by a college or university might also be called a doctor.

The word "doctor" comes from the Latin "docere" meaning to teach. A doctor was a teacher, especially a learned or authoritative one.
