This medication is used to treat heart failure. It is used by adults to help prevent the heart failure from getting worse and needing treatment in a hospital. It is also used by children who have heart failure due to an enlarged heart (dilated cardiomyopathy). Heart failure is a condition where your heart does not pump blood as well as it should. Ivabradine works by making your heart beat more slowly.
