Brand Names: Myfortic

What is Myfortic?

Myfortic (mycophenolic acid) is an immunosuppressant that weakens your body's immune system. Your body may "reject" an organ transplant when the immune system treats the new organ as an invader and attacks it. 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 may cause your body to overproduce white blood cells. This can lead to cancer, severe brain infection causing disability or death, or a viral infection causing kidney transplant failure.

Call your doctor right away if you have: fever, swollen glands, flu symptoms, vomiting, diarrhea, painful urination, easy bruising or bleeding, mouth sores, a new skin lesion, skin sores that are red or oozing, any change in your mental state, weakness on one side of your body, or tenderness near your transplanted kidney.

Myfortic can cause a miscarriage or birth defects when used during the first 3 months of pregnancy. If you are able to get pregnant, you must use birth control 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.

Before taking this medicine

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

Myfortic affects your immune system, and may cause certain white blood cells to grow out of control. This can lead to cancer, severe brain infection causing disability or death, or a viral infection causing kidney transplant failure. Talk with your doctor about the risks of using this medicine.

Tell your doctor if you have ever had:

  • a stomach ulcer or problems with digestion;

  • hepatitis B or C;

  • a viral, bacterial, or fungal infection; or

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

Mycophenolic acid 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. If you are able to get pregnant, you must use specific forms of birth control to prevent pregnancy while using Myfortic, and for at least 6 weeks after your last dose.

You are considered able to get pregnant (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. 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 are unable to use other needed transplant medications.

You should not breast-feed while using Myfortic.

How should I take Myfortic?

Take Myfortic exactly as prescribed by your docto Follow all directions on your prescription label and read all medication guides or instruction sheets.

You must remain under the care of a doctor while you are using Myfortic.

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

Swallow the tablet whole and do not crush, chew, or break it.

Mycophenolic acid (Myfortic) and mycophenolate mofetil (CellCept - a similar medicine also used to help the body from harming an organ after an organ transplant) are not absorbed equally in the body. Your dose needs may change if you switch to a different brand, strength, or form of this medicine. Avoid medication errors by using only the form and strength your doctor prescribes.

You will need frequent medical tests.

If you have ever had hepatitis B or C, mycophenolic acid can cause this virus to become active or get worse. You may need frequent liver function tests while using this medicine and for several months after you stop.

Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.
