What is CellCept?
CellCept weakens your body's immune system, to help keep it from "rejecting" a transplanted organ. Organ rejection happens when the immune system treats the new organ as an invader and attacks it.
CellCept is used with other immunosuppressant medicines containing cyclosporine and corticosteroids.
Cellcept can cause a miscarriage or birth defects when used during pregnancy. Both men and women should use effective birth control to prevent pregnancy during and shortly after treatment with CellCept.
Using CellCept may increase your risk of cancer, serious infections, or kidney transplant failure.
Call your doctor right away if you have symptoms such as: fever, swollen glands, weight loss, vomiting or diarrhea, painful urination, a new skin lesion, any change in your mental state, weakness on one side of your body, or pain near your transplanted kidney.
Before taking this medicine
You should not use CellCept if you are allergic to mycophenolate mofetil, mycophenolic acid, or polysorbate 80.
Talk with your doctor about the risks and benefits of CellCept. This medicine may increase your risk of cancer, serious or fatal infections, or a viral infection that can cause kidney transplant failure.
To make sure CellCept is safe for you, tell your doctor if you have ever had:
a stomach ulcer or problems with digestion;
hepatitis B or C or other viral infection (may become active or get worse while you are using mycophenolate mofetil);
phenylketonuria, or PKU (the liquid form of this medicine may contain phenylalanine); or
a rare inherited enzyme deficiency such as Lesch-Nyhan syndrome or Kelley-Seegmiller syndrome.
This medicine 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 CellCept, and for at least 6 weeks after your last dose.
Sexually active men and their partners should use effective contraception during treatment and for at least 90 days after the last dose.
CellCept can make birth control pills less effective. Ask your doctor about using an additional barrier form of birth control (condom, diaphragm, cervical cap, or contraceptive sponge) to prevent pregnancy.
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 CellCept. Call your doctor for instructions. Also call the Mycophenolate Pregnancy Registry (1-800-617-8191).
CellCept is sometimes given to pregnant women. Your doctor will decide whether you should use this medicine if you are unable to use other needed transplant medications.
