• Keep this leaflet, as you may need to read it again.
• If you have any questions, ask your doctor or pharmacist.

STAYVEER tablets contain bosentan, which blocks the natural hormone called endothelin-1 (ET-1), and causes narrowing of blood vessels. STAYVEER consequently causes dilation of blood vessels and belongs to the class of medications called “endothelin receptor antagonists”.

STAYVEER is used to treat:

• Pulmonary arterial hypertension(PAH): PAH is a severe narrowing of the blood vessels in the lungs, resulting in an increase in blood pressure in the blood vessels (pulmonary arteries) that carry blood from the heart to the lungs. This pressure reduces the amount of oxygen that can reach the blood in the lungs, making physical activity more difficult. STAYVEER widens the pulmonary arteries, making it easier for the heart to pump blood through them. This reduces blood pressure and alleviates symptoms.

STAYVEER is used to treat patients with PAH in class III to improve symptoms and exercise capacity (the ability to perform physical activity). The “class” reflects the severity of the disease: ‘class III’ implies a marked limitation of physical activity. Some improvements have been observed in patients with PAH class II. The ‘class II’ implies a slight limitation of physical activity. The PAH for which STAYVEER is indicated may be:

• primary (in which the cause or hereditary is not identified);
• caused by scleroderma (also known as systemic sclerosis, a disease in which there is abnormal growth of connective tissue that forms the support of the skin and other organs);
• caused by congenital heart defects (at birth) with short circuits (abnormal communications) that cause abnormal blood flow between the heart and lungs.

• Digital ulcers(ulcers on the fingers of the hands and feet) in adult patients with a disease called scleroderma. STAYVEER reduces the number of new digital ulcers (on hands and feet) that appear.

Do not take STAYVEER:

• if you are allergic to bosentanor to 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 be pregnantsince you are not using reliable contraceptive methods. Please read the information in the section “Contraceptives” and “Other medicines and STAYVEER”
• if you are taking ciclosporin A(a medicine used after a transplant or to treat psoriasis)

If you have any of these conditions, inform your doctor.

Warnings and precautions

Tests your doctor will perform before prescribing the treatment

• a blood test to assess liver function
• a blood test to detect if there is anemia (low hemoglobin)
• a pregnancy test if you are a fertile woman

Abnormalities in liver function tests and anemia have been found in some patients taking STAYVEER.

Tests your doctor will perform during the treatment

During treatment with STAYVEER, your doctor will schedule regular blood tests to monitor changes in your liver function and hemoglobin levels.

Please refer to the Patient Alert Card (inside the STAYVEER packaging) for these tests. It is essential to perform regular blood tests while taking STAYVEER. We suggest that you write the date of the most recent test and your next test (ask your doctor for the date) on the Patient Alert Card to help you remember when your next visit is.

Liver function tests

These tests must be performed monthly throughout the duration of treatment with STAYVEER. After a dose increase, an additional test should be performed after 2 weeks.

Anemia tests

These tests will be performed monthly during the first 4 months of treatment and then every 3 months, as patients taking STAYVEER may develop anemia.

If these tests are abnormal, your doctor may decide to reduce the dose or discontinue treatment with STAYVEER and perform additional tests to investigate the cause.

Children and adolescents

STAYVEER is not recommended for pediatric patients with systemic sclerosis and active digital ulceration. See also section 3. How to take STAYVEER.

Taking STAYVEER with other medicines

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medicine, including those purchased without a prescription. It is especially important to inform your doctor if you take:

Driving and operating machines

STAYVEER has no influence or has a negligible influence on driving and operating machines. However, STAYVEER may induce hypotension (low blood pressure) that may cause dizziness, affect your vision, and affect your ability to drive and operate machines. Therefore, if you feel dizzy or see blurry while taking STAYVEER, do not drive or operate tools or machinery.

Women of childbearing age

DO NOT TAKE STAYVEER if you are pregnant or plan to become pregnant

Pregnancy tests

STAYVEER may affect unborn babies conceived before or during treatment. If you are a fertile woman, your doctor will ask you to perform a pregnancy test before starting treatment with STAYVEER, and regularly while taking STAYVEER.

Contraceptives

If you may become pregnant, use a reliable contraceptive method (contraception) while taking STAYVEER. Your doctor or gynecologist will advise you on suitable contraceptive methods while taking STAYVEER. Since STAYVEER may make hormonal contraceptives ineffective (e.g., oral, injection, implant, or skin patches), this method alone is not reliable. Therefore, if you use hormonal contraceptives, you must also use a barrier method (e.g., female condom, diaphragm, spermicide, or your partner must also use a condom). Inside the STAYVEER packaging, you will find a Patient Alert Card that you must complete and bring to your doctor's next visit so that your doctor or gynecologist can determine if you need an alternative or additional reliable contraceptive method. It is recommended to perform a pregnancy test monthly while taking STAYVEER and are of childbearing age.

Inform your doctor immediately if you become pregnant while taking STAYVEER, or plan to become pregnant in the near future.
