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.
Dizziness or tiredness may occur. If either of these effects persists or worsens, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Ivabradine may rarely cause vision changes such as brief increased brightness, or seeing halos or colored bright lights. Sudden changes in light brightness may set off this effect. If vision changes happen, they usually start within the first 2 months and may go away during treatment or after stopping this medication.
Tell your doctor right away if you have any serious side effects, including: slow/fast/irregular heartbeat, fainting.
