What GN-CARVEDILOL is used for
GN-CARVEDILOL is used to treat heart failure.
GN-CARVEDILOL belongs to a group of medicines called beta-blockers. These medicines work by relaxing tightened blood vessels and slowing the heart rate. GN-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.
GN-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.
GN-CARVEDILOL reduces the chances of you being admitted to hospital and/or dying from this condition.
GN-CARVEDILOL is often used with other medicines to treat heart failure.
Your doctor, however, may have prescribed GN-CARVEDILOL for another purpose.
Ask your doctor if you have any questions about why GN-CARVEDILOL has been prescribed for you. GN-CARVEDILOL is not addictive.
This medicine is available only with a doctor’s prescription.
