    Uses of carvedilol

    The Food and Drug Administration (FDA) approves prescription drugs such as carvedilol for certain conditions. Approved uses for carvedilol oral tablet are described below. Carvedilol is used in adults. It’s usually prescribed as a long-term treatment.

    Use for high blood pressure

    Doctors may prescribe carvedilol oral tablet for treating high blood pressure.

    With high blood pressure, there usually aren’t any symptoms. But having high blood pressure increases the risk of serious problems, including heart attack and stroke.

    Use for heart failure

    Doctors may prescribe carvedilol oral tablet for treating heart failure.

    With heart failure, the heart becomes weak and enlarged. As a result, it can’t pump blood to the rest of the body as well as it should. Muscles and other organs don’t get enough fresh, oxygen-rich blood to meet their needs. This causes symptoms such as fatigue (low energy) and shortness of breath.

    Carvedilol may be prescribed for heart failure that’s mild to severe.

    Use for problems with the left ventricle after a heart attack

    Doctors may prescribe carvedilol oral tablet for treating problems with the left ventricle (one of the heart’s lower chambers) after a heart attack.

    Left ventricle problems are common after a heart attack. With left ventricle problems, the lower left chamber of the heart becomes weak. This chamber is responsible for pumping blood out to the rest of the body. When it’s weak, it can’t function as well as it should. This doesn’t always cause symptoms, but doctors can find the weakness with heart tests.

    Having left ventricle problems after a heart attack increases the risk of developing heart failure. It can even be fatal.

    Common questions about carvedilol

    Below you’ll find answers to a few commonly asked questions about carvedilol oral tablet.

    How does carvedilol compare with atenolol?

    Carvedilol and atenolol are similar drugs. Both atenolol and carvedilol belong to the same group of drugs, called beta-blockers. And they’re both approved to treat high blood pressure. Atenolol is also approved to treat a certain kind of chest pain and to help reduce the risk of dying during a heart attack.

    Since both carvedilol and atenolol are beta-blockers, they can cause similar side effects and have similar warnings. But their dosages are usually different.

    If you’d like more information about atenolol, talk with your doctor or pharmacist. Let your doctor know if you’re interested in taking atenolol. They can advise you about which drug is best for your condition.

    Does carvedilol cause long-term side effects?

    Not usually. Some of carvedilol’s mild side effects may ease as your body gets used to the drug. Others, such as a low heart rate, may continue based on how the drug works. Beta-blockers, such as carvedilol, are meant to slow your heart rate and lower your blood pressure. This is how they work to treat your condition.

    Talk with your doctor if you have side effects that aren’t going away or become bothersome or severe. They may be able to suggest ways to manage them. Or they may recommend changes in your treatment.

    Can carvedilol cause different side effects in older adults?

    It’s possible. Studies of the drug included older adults ages 65 years or older. Dizziness was reported more in older adults with high blood pressure as compared with younger adults. This may be because older adults could be more sensitive to the drug. But other side effects were the same in older adults and younger adults.

    If you’re an older adult and have questions about taking carvedilol, talk with your doctor. You can ask how carvedilol compares with other treatment options.

    How does carvedilol work? And how long does it take to start working?

    Carvedilol belongs to a group of drugs called beta-blockers. It works by relaxing your blood vessels, which helps lower blood pressure. Your heart doesn’t have to work as hard when your blood pressure is low because there’s less resistance to pump against. Carvedilol also slows your heart rate. This reduces the workload for your heart as well.

    Carvedilol will start working within about an hour of taking it. But it can take up to 2 weeks to see the full effects of the drug. If you and your doctor agree that you should stop taking carvedilol, it’ll take a couple of days for your body to clear it. This is based on a half-life of 7 to 10 hours. (A half-life is how long it takes your body to get rid of half of a dose of a medication.) It usually takes about five half-lives to get rid of a drug.

    If you have questions about starting or stopping carvedilol treatment, talk with your doctor or pharmacist.

    Note: Do not stop taking carvedilol without first talking with your doctor. Doing so can increase your risk of heart problems.

    Is there a best time of day to take carvedilol? What should I do if I miss a dose of carvedilol?

    Carvedilol is usually taken twice daily with food. For most people, this will mean taking it with breakfast and again with dinner or a late snack. Your doctor will recommend how and when to take carvedilol. Always follow your doctor’s instructions.

    If you miss a dose of carvedilol, take it as soon as you remember. But if it’s almost time for your next dose, skip the missed dose. Take the next dose at the regular time. Do not double up and take two doses. If you need help deciding whether to take a missed dose, talk with your doctor or pharmacist.

    Can carvedilol tablets be crushed, split, or chewed?

    The drugmaker doesn’t give any advice about crushing, splitting, or chewing carvedilol tablets. Ask your pharmacist about taking your prescription in any of these ways.
