Ivabradine
About Ivabradine
Ivabradine is an oral prescription medicine used to treat chronic heart failure and stable angina, which is a type of long-term chest pain. It works by lowering your heart rate, allowing your heart to pump blood more efficiently throughout your body. Doctors typically prescribe this medicine to improve your overall heart function and help prevent hospital stays related to worsening heart failure symptoms.
This medicine is usually taken twice a day, and it is highly important to take it consistently at the same times every day. You should always take Ivabradine with food, as meals help your body absorb the medicine properly and keep its levels steady in your system. Incorporating heart-healthy diet changes, such as reducing your salt intake, can significantly improve your treatment results.
Some people taking this medicine experience temporary vision changes, such as seeing sudden bright spots or flashes of light, as well as a slower heart rate than usual. While these mild issues often improve over time, you must consult your doctor immediately if you experience severe dizziness, fainting, shortness of breath, or an irregular heartbeat.
Before starting Ivabradine, tell your doctor if you have very low blood pressure or severe liver damage or if your heart rhythm is controlled entirely by a pacemaker. Do not take this medicine if you are pregnant, planning to become pregnant, or breastfeeding, as it can cause serious harm to a developing baby.
This medicine can interact with certain treatments, especially strong antifungals, antibiotics, or other heart medications that can drastically slow down your heart rate. You should avoid drinking grapefruit juice and limit alcohol while taking Ivabradine, as they can increase the risk of serious side effects. Specific user groups, including elderly individuals and those with kidney issues, should discuss their health history with a doctor before starting treatment.

Drug Warnings
- Check your heart rate before starting: Do not take Ivabradine if your resting heart rate is below 60 beats per minute before you begin the treatment.
- Be cautious when driving at night: This medicine can cause sudden, temporary changes in how you perceive light. Avoid driving or operating machinery in areas with sudden light changes, especially at night, until you know how the medicine affects your vision.
- Do not stop taking it suddenly: Stopping this medication abruptly can cause your heart rate to spike and worsen your heart failure or chest pain symptoms.
- Keep your healthcare team informed: Always tell any dentist, surgeon, or emergency room doctor that you are taking Ivabradine, as it can interact with anaesthetics or other procedures.
- Regular blood pressure checks: Ensure you regularly check your blood pressure, as sudden drops can increase dizziness while on this medication.
Drug Interactions
Drug-Drug Interactions
- Strong CYP3A4 inhibitors (e.g., certain antifungal or antibiotic medicines): These medications can significantly increase the levels of Ivabradine in your bloodstream by slowing its breakdown in the liver. This may increase the risk of excessive slowing of the heart rate (bradycardia), dizziness, fatigue, and other serious side effects.
- Heart-rate-lowering medicines (e.g., beta-blockers or certain calcium channel blockers): Taking these medicines together may have an additive effect on heart rate, increasing the risk of an excessively slow heartbeat, dizziness, fainting, or other cardiovascular complications.
- QT-prolonging medicines (e.g., certain antipsychotics or antiarrhythmic drugs): Combining Ivabradine with medicines that prolong the QT interval may increase the risk of serious irregular heart rhythms, including potentially life-threatening cardiac arrhythmias.
Drug-Food Interactions
- Grapefruit and grapefruit juice: Grapefruit products may interfere with the enzymes responsible for breaking down Ivabradine, leading to higher drug concentrations in the body. This can increase the risk of excessive slowing of the heart rate and other dose-related side effects.
Drug-Disease Interactions
- Severe liver disease: Patients with significant liver impairment may not clear Ivabradine effectively, increasing the risk of drug accumulation and toxicity. Closer monitoring or dose adjustments may be required.
- Sick sinus syndrome or heart block: Do not use Ivabradine if you have certain pre-existing heart rhythm disorders, such as sick sinus syndrome or advanced heart block, unless you have a functioning pacemaker. The medicine may further slow electrical conduction within the heart and worsen these conditions.
- Low blood pressure (hypotension): Use with caution if you have low blood pressure, as Ivabradine may further reduce blood pressure and increase the risk of dizziness, lightheadedness, or fainting.

Patients Concern
Disease/Condition Glossary
Stable angina pectoris: This condition is caused by reduced blood flow to the heart, when the heart is beating at a faster rate than normal to supply more oxygenated blood to the whole body. People dealing with angina may feel pressure, heaviness, and tightness in their chest.
Chronic Heart failure: Chronic Heart failure is also known as congestive heart failure, which happens when the heart fails to pump blood as much as it should. The possible factors include narrowed arteries in the heart, high blood pressure that weakens the heart, and the heart's inability to pump properly. The possible signs of heart failure include fatigue, rapid heartbeat, increased urge to urinate, rapid weight gain, severe shortness of breath, etc.
FAQs
Ivabradine is used to treat symptomatic stable angina pectoris and chronic heart failure.
Ivabradine contains Ivabradine, which works by reducing the heart rate by a few beats per minute. In this way, it lowers the heart's requirement for oxygen, especially in situations where an angina attack can happen. This helps control or reduce the chances of more angina attacks.
Yes, a woman should always take every measure, including a birth control pill, to prevent pregnancy while taking Ivabradine as this medicine can harm an unborn baby.
No, Ivabradine should not be used in those who are suffering from cardiogenic shock (a potentially fatal condition in which your heart suddenly cannot pump enough blood to fulfil your body's needs).
Do not stop taking Ivabradine on your own. After checking the heart activity, the doctor may reduce the dose before directly stopping the drug. A balanced diet, rest, and exercise are essential for maintaining good heart health, so the doctor may also recommend these lifestyle changes before discontinuing the medication directly.
Yes, a person taking Ivabradine needs to be under strict doctor's guidance. Monitoring the heart rate before the treatment and during the treatment is done to check the effects of the medicine. The monitoring of the heart is done with the help of an ECG.
No, usage of Ivabradine is prohibited in persons dealing with sick sinus syndrome, significant hypotension, or third-degree AV block. If you have any concerns regarding this, please discuss them with your doctor.
No, if a person is prescribed to take Ivabradine, they are strictly restricted from consuming grapefruit juice as it may worsen their side effects.
Ivabradine is a heart medicine (hyperpolarization-activated cyclic nucleotide-gated channel blocker) used to treat angina and heart failure.
Ivabradine may cause blurred/cloudy vision, double vision and impaired vision. Avoid driving, operating machinery or doing any activities that require proper vision until you know how this medicine affects you.
Overdose of Ivabradine may cause severe and prolonged bradycardia (slow heart rate), dizziness, lack of energy and excessive tiredness. Contact the doctor immediately if you experience these symptoms or if you have overdosed on Ivabradine.
Ivabradine may cause foetal toxicity. So, females of reproductive potential must use effective contraception whilst on treatment with Ivabradine. Regular monitoring of heart rhythm and heart rate is recommended.
Ivabradine does not lower blood pressure. It should not be used if you have very low blood pressure.
Ivabradine is not a beta-blocker. It belongs to the class of medications called hyperpolarisation-activated cyclic nucleotide-gated (HCN) channel blockers. It helps the heart pump more blood through the body by slowing the heart rate.
Side effects of Ivabradine include tiredness, irregular or rapid heartbeat, headache, dizziness, visual impairment or blurry vision. Consult the doctor if any of the side effects bother you.
This medicine can cause temporary vision changes, such as seeing sudden bright spots or halos around lights. These light flashes are harmless but can make driving at night or in areas with sudden light changes difficult. If you experience these visual symptoms, be extremely cautious and talk to your doctor about whether it is safe for you to drive.
If your resting heart rate drops below 50 beats per minute, or if you feel dizzy, extremely tired, or faint, do not take your next dose. Contact your healthcare provider immediately to discuss your symptoms. Talk to your doctor to see if your dose needs to be adjusted.
This medicine begins working to lower your heart rate within a few hours of taking your first doses. However, it may take several weeks of consistent use for you to notice a significant improvement in your daily breathing, energy levels, or chest pain frequency. Always take the medication as prescribed, and talk to your doctor if you have concerns about your progress.
In many cases of chronic heart failure, doctors may prescribe Ivabradine along with a beta-blocker to help manage your condition. However, because both medicines slow down your heart rate, this combination must be closely supervised by a professional to ensure your heart rate does not drop too low. Talk to your doctor or pharmacist for personalised guidance.
Some people taking this medicine experience harmless, temporary changes in vision, such as seeing sudden flashes of light, bright spots, or coloured halos. This happens because the medicine mildly interacts with similar electrical channels in the retina of your eye. These symptoms usually go away on their own, but if they are bothersome, talk to your doctor.
No, you should not take this medicine if you are pregnant, planning to become pregnant, or breastfeeding, as it may cause harm to the developing baby or infant. If you discover you are pregnant while taking this medicine, stop taking it and contact your healthcare provider immediately. Talk to your doctor to discuss safer treatment options.
