What this medicine is used for
The name of your medicine is APO-Carvedilol. It contains the active ingredient, carvedilol.
It is used to treat high blood pressure and, together with other medicines, to help treat congestive heart failure.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
Carvedilol belongs to a group of medicines called beta-blockers.
These medicines work by relaxing tightened blood vessels and slowing the heart rate. Carvedilol has the additional effect of being an antioxidant.
Heart failure occurs when the heart can no longer pump blood strongly enough for the body's needs. Often the heart grows in size to try to improve the blood flow but this can make the heart failure worse.
Symptoms of heart failure include shortness of breath and swelling of the feet or legs due to fluid build-up.
Carvedilol reduces the pressure that the heart has to pump against as well as controlling your heart rate. Over 6 months or more, this will reduce the size of an oversized heart and increase its efficiency.
Carvedilol reduces the chances of you being admitted to hospital for this condition.
Carvedilol is often used with other medicines to treat heart failure.
All people have blood pressure. This pressure helps to push blood all around your body. Your blood pressure changes during the day, depending on how busy you are or how you are feeling.
You have high blood pressure when your blood pressure stays higher than is needed, even when you are calm and relaxed.
Regular blood pressure checks are the only way of knowing that you have high blood pressure. There are usually no symptoms of high blood pressure and you may feel fine. If high blood pressure is not treated, serious health problems such as stroke, heart disease and kidney failure may occur.
Carvedilol helps to lower your blood pressure.
There is no evidence that the medicine is addictive.
Use in children
There is not enough information to recommend using this medicine for children.
