Patient leaflet - Bosentan Cipla 62.5 mg film-coated tablets
1. What Bosentan Tablet is and what it is used for
Bosentan Tablet contains bosentan, which blocks a 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 Tablet is 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 form 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 Tablet is used to treat patients with class III 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 Tablet is 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 Tablet reduces the number of new finger and toe ulcers that appear.
2. What you need to know before you take Bosentan Tablets

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

- 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”

Warnings and precautions
Talk to your doctor or pharmacist before taking Bosentan Cipla
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 Tablet is 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 with pulmonary arterial hypertension. Please see also section 3. How to take Bosentan Tablets.
Other medicines and Bosentan Tablets
Tell your doctor or pharmacist if you are taking, have recently taken or might take 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), , ketoconazole (a medicine used to treat Cushing’s syndrome), 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.
- other medications for the treatment of pulmonary hypertension: sildenafil and tadalafil,
- warfarin (an anticoagulant agent),
- simvastatin (used to treat hypercholesterolaemia).
Bosentan Tablets with food
Bosentan Tablets can be taken with or without food.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Women of child-bearing 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 child-bearing 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
Bosentan passes into your breast milk. You are advised to stop breast-feeding if bosentan is prescribed for you, because it is not known if bosentan in breast milk can harm your baby. Talk to your doctor about this.
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.
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, affect your vision and affect your ability to drive and use machines. Therefore, if you feel dizzy or that your vision is blurred while taking Bosentan Tablets, do not drive or operate any tools or machines.
Bosentan Cipla contains sodium
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.
3. How to take Bosentan Tablets

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Recommended dose:
Adults:
The treatment in adults is usually started for the first 4 weeks with 62.5 mg twice daily (morning and evening), from then your doctor will usually advise you to take a 125 mg tablet twice daily, depending on how you react to Bosentan Tablets.

For children 1 years and older, treatment with Bosentan Tablets is usually started with 2 mg 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. For such patients a bosentan tablet with lower strength is needed. Your doctor will advise you on your dosing. Please note that bosentan is also available as a dispersible 32 mg tablet formulation, which may make correct dosing easier for children and patients with low body weight or difficulties to swallow film-coated tablets.
If you have the impression that the effect of bosentan is too strong or too weak, talk to your doctor in order to find out whether your dose needs to be changed. How to take Bosentan Tablets
