Ivabradine is used by people with a certain heart problem (chronic heart failure), to help prevent it from getting worse and needing treatment in a hospital. 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. It should not be used if you have a slow resting heartbeat (less than 60 beats per minute) before starting ivabradine, low blood pressure, or if your heart failure symptoms have recently gotten worse. It is also given to patients who have stable angina pectoris (chest pain) and coronary artery disease.
Take this medication by mouth with a meal as directed by your doctor, usually twice daily. The dosage is based on your medical condition and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.
