Generic Name: carvedilol (kar-VE-dil-ol)
Brand Name: Coreg
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 an alpha- and 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 certain types of irregular heartbeat (eg, moderate to severe heart block, sick sinus syndrome), very severe heart failure (eg, requires treatment in a hospital), or shock caused by severe heart problems
- you have a very slow heartbeat and you do not have a permanent pacemaker
- 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, light-headedness, 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.
