INDICATION

WHAT IS CELLCEPT?

CellCept^®(mycophenolate mofetil) is a prescription medicine to prevent rejection (antirejection medicine) in people who have received a kidney, heart or liver transplant. Rejection is when the body’s immune system perceives the new organ as a “foreign” threat and attacks it.
CellCept is used with other medicines containing cyclosporine and corticosteroids.

WHAT IS THE MOST IMPORTANT INFORMATION I SHOULD KNOW ABOUT CELLCEPT?
CELLCEPT CAN CAUSE SERIOUS SIDE EFFECTS, INCLUDING:

Increased risk of loss of a pregnancy (miscarriage) and higher risk of birth defects. Females who take CellCept during pregnancy have a higher risk of miscarriage during the first 3 months (first trimester), and a higher risk that their baby will be born with birth defects.

If you are a female who can become pregnant, your doctor must talk with you about acceptable birth control methods (contraceptive counseling) to use while taking CellCept. You should have 1 pregnancy test immediately before starting CellCept and another pregnancy test 8 to 10 days later. Pregnancy tests should be repeated during routine follow-up visits with your doctor. Talk to your doctor about the results of all of your pregnancy tests. You must use acceptable birth control during your entire CellCept treatment and for 6 weeks after stopping CellCept, unless at any time you choose to avoid sexual intercourse (abstinence) with a man completely. CellCept decreases blood levels of the hormones in birth control pills that you take by mouth. Birth control pills may not work as well while you take CellCept, and you could become pregnant. If you take birth control pills while using CellCept you must also use another form of birth control. Talk to your doctor about other birth control methods that you can use while taking CellCept.
If you are a sexually active male whose female partner can become pregnant while you are taking CellCept, use effective contraception during treatment and for at least 90 days after stopping CellCept.
If you plan to become pregnant, talk with your doctor. Your doctor will decide if other medicines to prevent rejection may be right for you.
If you become pregnant while taking CellCept, do not stop taking CellCept. Call your doctor right away. You and your doctor may decide that other medicines to prevent rejection may be right for you. You and your doctor should report your pregnancy to the Mycophenolate Pregnancy Registry either:
- by phone at 1-800-617-8191 or
- by visiting the Risk Evaluation and Mitigation Strategy (REMS) website at www.mycophenolateREMS.com

The purpose of this registry is to gather information about the health of you and your baby.

Increased risk of getting certain cancers. People who take CellCept have a higher risk of getting lymphoma, and other cancers, especially skin cancer. Tell your doctor if you have:

unexplained fever, prolonged tiredness, weight loss or lymph node swelling
a brown or black skin lesion with uneven borders, or one part of the lesion does not look like the other
a change in the size and color of a mole
a new skin lesion or bump
any other changes to your health

Increased risk of getting serious infections. CellCept weakens the body’s immune system and affects your ability to fight infections. Serious infections can happen with CellCept and can lead to hospitalizations and death. These serious infections can include:

Viral infections. Certain viruses can live in your body and cause active infections when your immune system is weak. Viral infections that can happen with CellCept include:
- shingles, other herpes infections, and cytomegalovirus (CMV). CMV can cause serious tissue and blood infections
- BK virus. BK virus can affect how your kidney works and cause your transplanted kidney to fail
- hepatitis B and C viruses. Hepatitis viruses can affect how your liver works. Talk to your doctor about how hepatitis viruses may affect you
A brain infection called Progressive Multifocal Leukoencephalopathy (PML). In some patients, CellCept may cause an infection of the brain that may cause death. You are at risk for this brain infection because you have a weakened immune system. Call your doctor right away if you have any of the following symptoms:
- weakness on one side of the body
- you do not care about things that you usually care about (apathy)
- you are confused or have problems thinking
- you can not control your muscles
Fungal infections. Yeasts and other types of fungal infections can happen with CellCept and can cause serious tissue and blood infections (See “What are the possible side effects of CellCept?”).

Call your doctor right away if you have any of the following signs and symptoms of infection:

temperature of 100.5°F or greater
cold symptoms, such as a runny nose or sore throat
flu symptoms, such as an upset stomach, stomach pain, vomiting or diarrhea
earache or headache
pain during urination
white patches in the mouth or throat
unexpected bruising or bleeding
cuts, scrapes or incisions that are red, warm and oozing pus

WHAT ARE THE POSSIBLE SIDE EFFECTS OF CELLCEPT?
CELLCEPT CAN CAUSE SERIOUS SIDE EFFECTS, INCLUDING:

See “What is the most important information I should know about CellCept?”
Low blood cell counts. People taking high doses of CellCept each day may have a decrease in blood counts, including:
- white blood cells, especially neutrophils. Neutrophils fight against bacterial infections. You have a higher chance of getting an infection when your white blood cell count is low. This is most common from 1 month to 6 months after your transplant
- red blood cells. Red blood cells carry oxygen to your body tissues. You have a higher chance of getting severe anemia when your red blood cell count is low
- platelets. Platelets help with blood clotting

Your doctor will do blood tests before you start taking CellCept and during treatment with CellCept to check your blood cell counts. Tell your doctor right away if you have any signs of infection (see “What is the most important information I should know about CellCept?”), including any unexpected bruising or bleeding. Also, tell your doctor if you have unusual tiredness, lack of energy, dizziness or fainting.
Stomach problems. Stomach problems including intestinal bleeding, a tear in your intestinal wall (perforation) or stomach ulcers can happen in people who take CellCept. Bleeding can be severe and you may have to be hospitalized for treatment. Call your doctor right away if you have sudden or severe stomach-area pain or stomach-area pain that does not go away, or if you have diarrhea.

The most common side effects of CellCept include:

diarrhea
blood problems including low white and red blood cell counts
infections
blood pressure problems
fast heart beat
swelling of the lower legs, ankles and feet
changes in laboratory blood levels, including high levels of blood sugar (hyperglycemia)
stomach problems including diarrhea, constipation, nausea and vomiting
rash
nervous system problems such as headache, dizziness and tremor

Side effects that can happen more often in children than in adults taking CellCept include:

stomach area pain
fever
infection
pain
blood infection (sepsis)
diarrhea
vomiting
sore throat
colds (respiratory tract infections)
high blood pressure

These are not all of the possible side effects of CellCept. Tell your doctor about any side effect that bothers you or that does not go away. Call your doctor for medical advice about side effects.
