What is Corlanor?
Corlanor (ivabradine) works by affecting your heart's electrical activity in order to slow the heart rate.
Corlanor is used in certain people with chronic heart failure, to help lower the risk of needing to be hospitalized when symptoms get worse.
Corlanor is not for use if you already have heart failure symptoms that recently got worse before starting this medicine.
You should not use Corlanor if you have severe liver disease, if you depend on a pacemaker to regulate your heart rate, or if you have a serious heart condition such as "sick sinus syndrome" or 3rd-degree "AV block" (unless you have a pacemaker).
You also should not use Corlanor if your heart failure symptoms recently got worse, if your resting heart rate is less than 60 bpm, or if your blood pressure is less than 90 over 50.
Avoid becoming pregnant while you are taking Corlanor. Use effective birth control and tell your doctor right away if you become pregnant.
Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact with ivabradine, and some drugs should not be used together.
Corlanor can cause serious heart rhythm problems. Call your doctor at once if you have chest tightness, racing or pounding heartbeats, very slow heartbeats, weakness, tiredness, severe dizziness, or shortness of breath that is worse than usual.

How should I take Corlanor?
Take Corlanor exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Corlanor is usually taken 2 times per day with meals. Avoid eating grapefruit or drinking grapefruit juice with this medicine.
You may also need to take another medicine called a beta-blocker. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice.
Corlanor can cause a temporary brightness in your vision, especially during the first 2 months of treatment. This can make you see halos around lights, see colors within lights, or see multiple images while looking at an object. You may also see kaleidoscope colors or flashes of movement in certain parts of your vision. Sudden bright light can make these vision changes more noticeable. These effects usually go away as you continue taking Corlanor or after you stop taking it.
While using Corlanor, you may need frequent medical tests. Your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG).
Store at room temperature away from moisture and heat.
