About ivabradine

Angina is a pain that comes from the heart. It is usually caused by the narrowing of one or more of the arteries that supply blood to your heart. This narrowing reduces the blood supply to parts of your heart muscle. When your heart needs more blood and oxygen than it can get through the narrowed arteries (for example, when you walk fast or climb stairs), you feel angina pain.

Insuficiência cardíaca is a condition where your heart does not pump as effectively as it once did. This causes problems getting blood and oxygen to the rest of your body.

Ivabradine works by slowing down your heart rate a little. Because your heart is working less quickly, the amount of oxygen your heart needs is reduced. If you have been prescribed ivabradine to prevent angina, this will help to reduce the number of angina attacks you have. It also means that your heart needs to do less work to pump blood around your body if you have heart failure.

Before taking ivabradine

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking ivabradine it is important that your doctor knows:

• Se você está grávida ou amamentando.

• If you know you have a slow or irregular heart rhythm.

• If you know you have low blood pressure.

• If you have a pacemaker fitted.

• If you have recently had a stroke or a heart attack.

• If you have a problem with the retina of your eye.

• Se você tiver algum problema com o funcionamento do seu fígado, ou qualquer problema com o funcionamento dos seus rins.

• Se você já teve uma reação alérgica a um medicamento.

• Se você estiver tomando ou usando qualquer outro medicamento. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.
  

How to take ivabradine

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about ivabradine and will also provide you with a full list of side-effects which you could experience from taking it.

• Take ivabradine exactly as your doctor tells you to. It is usual to take a dose twice daily, one in the morning and the other in the evening. When starting your treatment, your doctor may give you a small dose (such as half of a 5 mg tablet) and then increase it after a short while. This will help avoid any unwanted side-effects, particularly dizziness. There are two strengths of tablet available - 5 mg and 7.5 mg. Your doctor will tell you which is right for you to continue treatment with.

• Try to take your doses at the same times of day each day, as this will help you to remember to take ivabradine regularly. Take the tablet during a meal with a drink of water. Do not chew or crush the tablets.

• If you forget to take a dose at your usual time, take it when you remember. However, if it is nearly time to take your next dose when you remember, then leave out the forgotten dose and take your next dose when it is due. Do not take two doses together to make up for a missed dose.

• Ivabradine tablets are not suitable to take to relieve pain if you are having an angina attack. Your doctor will also prescribe a nitrate medicine, such as glyceryl trinitrate (GTN), for you to take if this happens. If after using GTN your pain has not eased within a few minutes, call for an ambulance.

• Try to keep your regular appointments with your doctor. This is so your doctor can monitor your progress and check your heart rate.

• It is best to avoid or limit the amount of grapefruit juice you drink while you are on ivabradine. This is because a chemical in grapefruit juice increases the amount of ivabradine in your bloodstream. This makes side-effects more likely.

• If you buy any medicines 'over the counter', please check with a pharmacist that they are suitable for you to take with your prescribed medicines.

• Se você estiver prestes a fazer uma operação ou qualquer tratamento dentário, por favor, informe à pessoa que está realizando o tratamento quais medicamentos você está tomando.
