טבליות

Pulmonary arterial hypertension (PAH) is a condition where there is too high a blood pressure in the arteries which supply blood to your lungs from your heart. The arteries become narrowed so your heart has to work harder to pump blood to your lungs.

Macitentan relaxes the muscles in the walls of the arteries, allowing the blood vessels to become wider. This reduces the pressure in the arteries and allows blood to flow more easily through them. In turn, this increases the supply of blood to your lungs and improves your ability to do physical activities. Macitentan will be prescribed for you by a doctor who is a specialist.

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

  • אם יש לך בעיות בתפקוד הכבד שלך, או אם יש לך בעיות בתפקוד הכליות שלך.

  • If you have been told you have a reduced number of red blood cells (anaemia).

  • אם את בהריון, מנסה להיכנס להריון, או מניקה.

  • If you have ever had an allergic reaction to a medicine, or if you are allergic to soya.

  • אם אתה נוטל תרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack, along with any information you have been given by your hospital. The manufacturer's leaflet will give you more information about macitentan and a full list of side-effects which you may experience from taking it.

  • Take macitentan exactly as your doctor tells you to. The usual dose is one 10 mg tablet daily. Try to take your doses at the same time of day each day, as this will help you to remember to take the tablets regularly.

  • Swallow the tablet whole with a drink of water. You can take macitentan either before or after food.

  • If you forget to take a dose at your usual time, take it as soon as you remember. If you do not remember until the following day, skip the forgotten dose. Do not take two doses at the same time to make up for a missed dose.

  • Try to keep your regular appointments with your doctor so your progress can be checked. Your doctor will want you to have some blood tests both before and during your treatment. The tests will check that your liver is staying healthy.

  • Treatment with macitentan is usually long-term. Continue to take the tablets unless you are advised otherwise.

  • If you buy any medicines 'over the counter', always check with a pharmacist that they are suitable for you to take. The herbal medicine called St John's wort can interfere with macitentan so you should not take preparations containing this ingredient.

  • If you are due to have an operation or some other medical treatment, it is important that you tell the person carrying out the treatment that you are on macitentan.

  • Women with pulmonary hypertension should avoid becoming pregnant as pregnancy can lead to serious worsening of your condition. Women of childbearing potential must use effective contraception during treatment with macitentan. Speak with your doctor about which contraceptive methods are suitable for you.

שאלות נפוצות

What is pulmonary arterial hypertension (PAH) and how does macitentan help?

Pulmonary arterial hypertension (PAH) is a condition where the blood pressure in the arteries supplying blood from your heart to your lungs is too high. These arteries become narrowed, making your heart work harder. Macitentan works by relaxing the muscles in the walls of these arteries, causing the blood vessels to widen. This reduces the pressure and allows blood to flow more easily to your lungs, which improves your ability to do physical activities.

How often will I need to see my doctor while taking macitentan?

You should try to keep your regular appointments with your doctor. These appointments are important so your doctor can check your progress and ensure your treatment is working effectively. You will also need to have blood tests both before and during your treatment to check that your liver remains healthy.

Are there any specific over-the-counter medicines or herbal remedies I should avoid while on macitentan?

Yes, it is important to be cautious with over-the-counter medicines and herbal remedies. You should always check with a pharmacist to make sure they are suitable for you. Specifically, the herbal medicine St John's wort can interfere with macitentan, so you should not take any preparations containing this ingredient.

If I'm a woman, what should I know about pregnancy and macitentan?

Women with pulmonary hypertension should avoid becoming pregnant because pregnancy can severely worsen your condition. If you are a woman of childbearing potential, you must use effective contraception throughout your treatment with macitentan. You should discuss suitable contraceptive methods with your doctor.

What should I do if I experience changes in my appetite or feel very tired while taking macitentan?

Macitentan can potentially cause liver damage, and your doctor will discuss this with you. If you experience symptoms such as loss of appetite, extreme tiredness, dark urine, itching, yellowing of your skin or eyes (jaundice), constantly feeling sick (nausea) or being sick (vomiting), or pain in your tummy (abdomen), you should tell your doctor straightaway. These could be signs of liver damage, and your doctor will want to check this with a blood test.

What should I do if I feel dizzy while taking macitentan?

Feeling dizzy can be a symptom of your condition or a side-effect of macitentan. If you start to feel dizzy, it's advised to sit or lie down for a few minutes to prevent fainting, and then get up slowly. You should not drive or operate tools or machinery if you are feeling dizzy.
