1.    What Bosentan Tablets are and what they are used for

Bosentan Tablets contain bosentan which blocks naturally occurring hormone called endothelin-1 (ET-1), which causes blood vessels to narrow. Bosentan Tablets therefore causes blood vessels to expand and belongs to the class of medicines called “endothelin receptor antagonists”.

Bosentan Tablets are used to treat:

-    Pulmonary arterial hypertension (PAH): PAH is a disease of severe narrowing of the blood vessels in the lungs resulting in high blood pressure in the blood vessels (the pulmonary arteries) that carry blood from the heart to the lungs. This pressure reduces the amount of oxygen that can get into the blood in the lungs, making physical activity more difficult. Bosentan Tablets widens the pulmonary arteries, making it easier for the heart to pump blood through them. This lowers the blood pressure and relieves the symptoms.

Bosentan Tablets are used to treat patients with class III pulmonary arterial hypertension (PAH) to improve exercise capacity (the ability to carry out physical activity) and symptoms. The ‘class’ reflects the seriousness of the disease: ‘class III’ involves marked limitation of physical activity. Some improvements have also been shown in patients with class II PAH. ‘Class II’ involves slight limitation of physical activity. The PAH for which Bosentan Tablets are indicated can be:

-    primary (with no identified cause or familial);

-    caused by scleroderma (also called systemic sclerosis, a disease where there is abnormal growth of the connective tissue that supports the skin and other organs);

-    caused by congenital (inborn) heart defects with shunts (abnormal passageways) causing abnormal flow of blood through the heart and lungs.

-    Digital ulcers (sores on the fingers and toes) in adult patients with a condition called scleroderma. Bosentan Tablets reduce the number of new finger and toe ulcers that appear.

2.    What you need to know before you take Bosentan Tablets Do not take Bosentan Tablets:

-    if you are allergic to bosentan or any of the other ingredients of this medicine (listed in section 6)

-    if you have liver problems (ask your doctor)

-    if you are pregnant, or could get pregnant because you are not using reliable contraceptive methods. Please read the information under “contraceptives” and “Other medicines and Bosentan Tablets

-    if you are taking cyclosporine A (a medicine used after a transplant or to treat psoriasis).

If any of these apply to you, tell your doctor.

Warnings and precautions

Talk to your doctor or pharmacist before taking Bosentan Tablets.

Tests your doctor will do before treatment

-    a blood test to check your liver function

-    a blood test to check for anaemia (low haemoglobin)

-    a pregnancy test if you are a woman of child-bearing potential

Some patients taking Bosentan Tablets have been found to have abnormal liver function tests and anaemia (low haemoglobin).

Tests your doctor will do during treatment

During treatment with Bosentan Tablets, your doctor will arrange for regular blood tests to check for changes in your liver function and haemoglobin level.

For all these tests please refer also to the Patient Alert Card (inside your pack of Bosentan Tablets). It is important that you have these regular blood tests as long as you are taking Bosentan Tablets. We suggest you write the date of your most recent test and also of your next test (ask your doctor for the date) on the Patient Alert Card, to help you remember when your next test is due.

Blood tests for liver function

These will be done every month for the duration of treatment with Bosentan Tablets. After an increase in dose an additional test will be done after 2 weeks.

Blood tests for anaemia

These will be done every month for the first 4 months of treatment, then every 3 months after that, as patients taking Bosentan Tablets may get anaemia.

If these results are abnormal, your doctor may decide to reduce your dose or stop treatment with Bosentan Tablets and to perform further tests to investigate the cause.

Children and adolescents

Bosentan Tablets are not recommended in paediatric patients with systemic sclerosis and ongoing digital ulcer disease. Bosentan Tablets should also not be used in children with a body weight below 31 kg and certain other weight ranges with pulmonary arterial hypertension. Please see also section 3. How to take Bosentan Tablets.

Other medicines and Bosentan Tablets

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. It is especially important to tell your doctor if you are taking:

-    cyclosporine A (a medicine used after transplants and to treat psoriasis), which must not be used together with Bosentan Tablets

-    sirolimus or tacrolimus, which are medicines used after transplants, as these are not recommended to be used together with Bosentan Tablets

-    glibenclamide (a diabetes medicine), rifampicin (a tuberculosis medicine) or fluconazole (a medicine against fungal infections), nevirapine (an HIV medicine) as these medicines are not recommended to be used together with Bosentan Tablets

-    other medicines for the treatment of HIV infection, which may require special monitoring if used together with Bosentan Tablets

-    hormonal contraceptives, which are not effective as the sole method of contraception when you take Bosentan Tablets. Inside your pack of Bosentan Tablets you will find a Patient Alert Card which you should read carefully. Your doctor and/or gynaecologist will establish the contraception which is appropriate for you.

Driving and using machines

Bosentan Tablets has no or negligible influence on the ability to drive and use machines. However, Bosentan Tablets can induce hypotension (decrease of your blood pressure) which can make you feel dizzy and affect your ability to drive and use machines. Therefore, if you feel dizzy while taking Bosentan Tablets, do not drive or operate any tools or machines.

Women of childbearing age

Do NOT take Bosentan Tablets if you are pregnant or planning to become pregnant.

Pregnancy tests

Bosentan Tablets may harm unborn babies conceived before starting or during treatment. If you are a woman who could become pregnant, your doctor will ask you to take a pregnancy test before you start taking Bosentan Tablets, and regularly while you are taking Bosentan Tablets.

Contraceptives

If it is possible that you could become pregnant, use a reliable form of birth control (contraception) while you are taking Bosentan Tablets. Your doctor or gynaecologist will advise you about reliable contraceptive methods while taking Bosentan Tablets. Because Bosentan Tablets may make hormonal contraception (e.g., oral, injection, implant, or skin patches) ineffective, this method on its own is not reliable. Therefore, if you use hormonal contraceptives you must also use a barrier method (e.g., female condom, diaphragm, contraceptive sponge, or your partner must also use a condom). Inside your pack of Bosentan Tablets you will find a Patient Alert Card. You should complete this card and take it to your doctor at your next visit so that your doctor or gynaecologist can assess whether you need additional or alternative reliable contraceptive methods. Monthly pregnancy tests are recommended while you are taking Bosentan Tablets and are of childbearing age.

-    Tell your doctor immediately if you become pregnant while you are taking Bosentan Tablets, or plan to become pregnant in the near future.

Breast feeding

Tell your doctor immediately if you are breast feeding. You are advised to stop breast feeding if Bosentan Tablets is prescribed for you, because it is not known whether this medicine passes into breast milk.

Fertility

If you are a man taking Bosentan Tablets, it is possible that this medicine may lower your sperm count. It cannot be excluded that this may affect your ability to father a child. Talk to your doctor if you have any questions or concerns about this.

3. How to take Bosentan Tablets

Treatment with Bosentan Tablets is usually started with 2mg per kg bodyweight twice daily (morning and evening); however, some doses of bosentan are not possible in children with a body weight below 31 kg and certain other weight ranges. For such patients a bosentan tablet with lower strength is needed. Your doctor will advise you on your dosing.

Pregnancy

Bosentan Tablets may harm the development of the foetus. Therefore, you should not take Bosentan Tablets if you are pregnant and you should also not become pregnant while taking Bosentan Tablets. Moreover, if you are suffering from pulmonary hypertension disease, the occurrence of a pregnancy can severely deteriorate the symptoms of your disease. If you suspect you may be pregnant, tell your doctor or gynaecologist.


Contraception

Birth control based on hormones, such as oral contraceptives or birth control pills, hormone injections, implants, or birth control skin patches don’t reliably prevent pregnancy in women who are taking Bosentan Tablets. You need to use a barrier form of birth control like a condom, diaphragm or vaginal sponge, in addition to any of these kinds of hormonal birth control. Be sure to discuss any questions you may have with your doctor or your gynaecologist.

Complete the details on the back of this card and take it to your doctor or gynaecologist at your next visit.

You should have a pregnancy test before initiation of Bosentan Tablets and every month during the treatment even if you think that you are not pregnant.
