Before taking this medicine
You should not use Tracleer if you are allergic to it, or if you are pregnant or might become pregnant during treatment.
Some medicines can interact with Tracleer and should not be used at the same time. Your doctor may need to change your treatment plan if you use any of the following drugs:
To make sure Tracleer is safe for you, tell your doctor if you have:
if you have had or will have a heart or kidney transplant.
Do not use Tracleer if you are pregnant or think you might be pregnant. This medicine can cause serious birth defects. Tell your doctor right away if you miss a menstrual period or think you may have become pregnant during treatment.
You will need to have a negative pregnancy test before starting this treatment. You will be re-tested every month during your treatment, and 1 month after you stop taking this medicine.
Even if you are not planning a pregnancy, you are considered able to become pregnant if:
you have entered puberty (even if you have not yet started having periods);
you have never had a hysterectomy or had your ovaries removed; or
you have not gone through menopause (you have never gone 12 months in a row without a menstrual period).
While taking Tracleer and for at least 30 days after your last dose, you must use a highly effective form of birth control or two methods together.
A tubal ligation alone is an effective birth control method.
An intrauterine device (IUD) alone is also an effective birth control method.
If you use birth control pills, implants, injections, skin patches, or vaginal rings, you must use a back-up barrier form of birth control, such as a condom or diaphragm or cervical cap. Always use a spermicide gel or insert together with a barrier form of birth control.
If your sexual partner has had a vasectomy, you must still use a second method of birth control--either a barrier method or a hormonal form (birth control pills, injections, skin patch, or vaginal ring).
Tracleer comes with patient instructions about acceptable forms of birth control to use while taking this medicine. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
If you are the parent or caregiver of a female child taking this medicine, talk to the child's doctor once you notice any signs of puberty (breast development or pubic hair), even if menstrual periods have not yet begun.
Tracleer can decrease sperm count and may affect fertility in men (your ability to have children).
It is not known whether bosentan passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
How should I take Tracleer?
Tracleer is usually taken 2 times per day. Your doctor may change your dose after 4 weeks of treatment. Follow all directions on your prescription label. Do not take Tracleer in larger or smaller amounts or for longer than recommended.
You may take Tracleer with or without food.
Do not swallow a dispersible tablet whole. Place it into a small amount of water and allow the tablet to disperse in the liquid. The tablet will not dissolve completely. Stir gently and drink this mixture right away.
If your doctor tells you to use only half of a dispersible tablet, break the tablet at the line scored on it and disperse only one tablet half in water. Place the unused tablet half back into the blister pack for storage, and use that half within 7 days. Do not break a tablet half into smaller pieces.
Tracleer can cause severe liver problems. Your liver function will need to be tested before you start taking this medicine, and again each month during your treatment.
Your blood cells may also need to be tested during treatment and for up to 3 months after you stop taking this medicine.
You should not stop using Tracleer suddenly. Stopping suddenly may make your condition worse. Follow your doctor's instructions about tapering your dose.
Store at room temperature away from moisture and heat.
