It's like having a pharmacist for a best friend
Ivabradine is a heart medication that is used in addition to other medications to treat stable, chronic (long-term) heart failure in adults who have a heart rate of 77 or more beats per minute. It reduces the heart rate by acting on specific cells in the heart that cause the heart muscle to contract, or "beat." An increased heart rate is associated with increased hospital admissions and an increased risk of dying from heart failure.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Driving and using machines: Ivabradine may cause blurred vision and dizziness or weakness affecting your ability to drive or operate machinery. Avoid these and other hazardous tasks until you have determined how this medication affects you.
Heart rhythm: Ivabradine is intended to slow the heart rate down; however, it can cause other changes to the normal rhythm of the heart. If this medication causes your heart rate to slow down too much, it may leave you feeling unusually tired, or lightheaded.
Ivabradine may cause an increased risk of developing atrial fibrillation, a condition where the two smaller chambers of the heart beat rapidly and irregularly. People with atrial fibrillation may experience shortness of breath, a pounding heartbeat or dizziness.
Ivabradine may cause an irregular heartbeat called QT prolongation. QT prolongation is a serious life-threatening condition that can cause fainting, seizures, and sudden death. If you are at risk for heart rhythm problems (e.g., people with heart failure, angina, low potassium or magnesium levels), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Your doctor will monitor your heart rhythm regularly while you are taking this medication with a test called an electrocardiogram (ECG). You should not take this medication if your ECG already shows that you have QT prolongation or if you are taking a medication that can cause QT prolongation.
Contact your doctor if you experience symptoms of irregular heartbeat.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.
Vision changes: This medication may affect your vision, causing blurring or spots of light. Contact your doctor if you notice any changes in your vision.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if ivabradine passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take.
