Myfortic

Pronunciation

Generic Name: mycophenolic acid (MYE koe phe NOLE ik AS id)
Brand Names: Myfortic

What is Myfortic?

Myfortic (mycophenolic acid) is an immunosuppressant. Your body may "reject" an organ transplant when the immune system treats the new organ as an invader. An immunosuppressant helps to prevent this rejection.

Myfortic is used to prevent your body from rejecting a kidney transplant. Myfortic is usually given with cyclosporine and a steroid medicine.

Important information

Myfortic can cause a miscarriage or birth defects, especially if used during the first 3 months of pregnancy. If you are a woman of child-bearing potential, you must use specific types of birth control to prevent pregnancy before, during, and shortly after treatment with Myfortic.

Myfortic is sometimes given to pregnant women. Although this medicine can affect pregnancy or fertility, it is sometimes given to women who are unable to use other needed transplant medications.

Using Myfortic may increase your risk of developing serious infections or other types of cancer, such as lymphoma or skin cancer. You must remain under the care of a doctor while you are using Myfortic.

Call your doctor right away if you have signs of infection such as: fever, swollen glands, flu symptoms, change in your mental state, problems with speech or walking, decreased vision, mouth sores, easy bruising or bleeding, pain or burning when you urinate, blood in your urine, a new skin lesion, or a mole that has changed in size or color.

Before taking this medicine

You should not use Myfortic if you are allergic to mycophenolic acid or mycophenolate mofetil (CellCept).

Using Myfortic may increase your risk of developing serious infections or other types of cancer, such as lymphoma or skin cancer. Ask your doctor about your specific risk.

To make sure Myfortic is safe for you, tell your doctor if you have:

  • a stomach ulcer or other disorder of your stomach or intestines;

  • a viral, bacterial, or fungal infection; or

  • a rare inherited enzyme deficiency such as Lesch-Nyhan syndrome or Kelley-Seegmiller syndrome.

FDA pregnancy category D. Myfortic can cause a miscarriage or birth defects, especially during the first 3 months of pregnancy. You will need to have a negative pregnancy test before and during treatment with this medicine. You must prevent pregnancy before and during your treatment with Myfortic, and for at least 6 weeks after your treatment ends.

If you are a woman of child-bearing potential, you will be required to use birth control. You have child-bearing potential (even if you are not sexually active) from the age of puberty until you have been in menopause for at least 12 months in a row.

Myfortic can make hormonal birth control (pills, injections, implants, skin patches, or vaginal rings) less effective. If you use hormonal birth control, you must also use a back-up barrier method (such as a cervical sponge, a male or female condom, or a diaphragm or cervical cap used together with spermicide).

You do not need to use additional birth control if you use an intrauterine device (IUD), if you have had a tubal ligation, or if your sexual partner has had a vasectomy.

This medicine comes with patient instructions about the most effective non-hormonal forms of birth control to use. Follow these directions carefully. Ask your doctor if you have any questions.

If a pregnancy occurs during treatment, do not stop taking Myfortic. Call your doctor for instructions. Also call the Mycophenolate Pregnancy Registry (1-800-617-8191).

Myfortic is sometimes given to pregnant women. Your doctor will decide whether you should use this medicine if you are pregnant or planning to become pregnant. Although this medicine can affect pregnancy or fertility, it is sometimes given to women who are unable to use other needed transplant medications.

It is not known whether mycophenolic acid 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 Myfortic?

Take Myfortic exactly as prescribed by your doctor. You must remain under the care of a doctor while you are using Myfortic. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Take Myfortic on an empty stomach, at least 1 hour before or 2 hours after a meal.

Do not crush, chew, or break a delayed-release tablet. Swallow it whole.

Mycophenolic acid (Myfortic) and mycophenolate mofetil (CellCept) are not absorbed equally in the body. If you are switched from one brand to the other, take only the pills your doctor has prescribed. Always check your refills to make sure you have received the correct brand and type of medicine.

You will need regular medical tests to be sure this medicine is not causing harmful effects.

If you have ever had hepatitis B or C, Myfortic can cause this condition to come back or get worse. You may need blood tests to check your liver function.
