What are the uses of this medicine?

• Mycophenolate mofetil (CellCept) 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.
• Mycophenolate mofetil (CellCept) is used with other medicines containing cyclosporine and corticosteroids.

How does this medicine work?

• The morpholinoethyl ester of mycophenolic acid (MPA) with potent immunosuppressive properties.
• Mycophenolate stops T-cell and B-cell proliferation through selective inhibition of the de novo pathway of purine biosynthesis.
• In vivo, the active metabolite, MPA, reversibly inhibits inosine 5'-monophosphate dehydrogenase, an enzyme involved in the de novo synthesis of guanine nucleotides.
• MPA displays high lymphocyte specificity and cytotoxicity due to the higher dependence of activated lymphocytes on both salvage and de novo synthesis of guanine nucleotides relative to other cell types.

Who Should Not Use this medicine ?

This medicine cannot be used in patients:

• with a hypersensitivity to mycophenolate mofetil (MMF), mycophenolic acid (MPA) or any component of the drug product.
• who are allergic to Polysorbate 80 (TWEEN).

What drug interactions can this medicine cause?

• Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

Be sure to mention any of the following:

• birth control pills (oral contraceptives).
• sevelamer (Renagel®, Renvela™). These products should be taken at least 2 hours after taking CellCept.

• rifampin (Rifater®, Rifamate®, Rimactane®, Rifadin®).
• antacids that contain magnesium and aluminum (CellCept and the antacid should not be taken at the same time).

• These patients should be carefully monitored.

Neutropenia:

Administration:

• Take CellCept exactly as prescribed.
• Do not stop taking CellCept or change the dose unless your doctor tells you to.
• If you miss a dose of CellCept, or you are not sure when you took your last dose, take your prescribed dose of CellCept as soon as you remember.

• Take CellCept capsules, tablets and oral suspension on an empty stomach, unless your doctor tells you otherwise.
• Do not crush CellCept tablets.

• Do not mix CellCept Oral Suspension with any other medicine.
• CellCept Oral Suspension should not be mixed with any type of liquids before taking the dose.

What special precautions should I follow?

• Use of MMF during pregnancy is associated with an increased risk of first trimester pregnancy loss and an increased risk of congenital malformations, especially external ear and other facial abnormalities including cleft lip and palate, and anomalies of the distal limbs, heart, esophagus, kidney and nervous system. Avoid use of MMF during pregnancy if safer treatment options are available.
• Patients receiving immunosuppressants, including CellCept, are at increased risk of developing lymphomas and other malignancies, particularly of the skin. For patients with increased risk for skin cancer, exposure to sunlight and UV light should be limited by wearing protective clothing and using a broad-spectrum sunscreen with a high protection factor.
• Post-transplant lymphoproliferative disorder (PTLD) developed in patients receiving CellCept (2 g or 3 g) with other immunosuppressive agents in controlled clinical trials of kidney, heart and liver transplant patients.
• Patients receiving immunosuppressants, including CellCept, are at increased risk of developing bacterial, fungal, protozoal and new or reactivated viral infections, including opportunistic infections. Consider dose reduction or discontinuation of CellCept in patients who develop new infections or reactivate viral infections.
• Severe neutropenia developed in transplant patients receiving CellCept 3 g daily. Monitor with blood tests; consider treatment interruption or dose reduction.
• Gastrointestinal bleeding requiring hospitalization, ulceration and perforations were observed in clinical trials. Physicians should be aware of these serious adverse effects particularly when administering CellCept to patients with a gastrointestinal disease.
• CellCept is an inosine monophosphate dehydrogenase (IMPDH) inhibitor; therefore it should be avoided in patients with hereditary deficiencies of hypoxanthine-guanine phosphoribosyl-transferase (HGPRT) such as Lesch-Nyhan and Kelley-Seegmiller syndromes.
• Acute inflammatory syndrome (AIS) has been reported with the use of MMF and mycophenolate products, and some cases have resulted in hospitalization. Monitor patients for symptoms and laboratory parameters of AIS when starting treatment with mycophenolate products or when increasing the dosage. Discontinue treatment and consider other treatment alternatives based on the risk and benefit for the patient.
• During treatment with CellCept, the use of live attenuated vaccines should be avoided. Advise patients to discuss with the physician before seeking any immunizations.
• CellCept Intravenous solution must not be administered by rapid or bolus intravenous injection as rapid infusion increases the risk of local adverse reactions such as phlebitis and thrombosis.
• Phenylalanine can be harmful to patients with phenylketonuria (PKU). CellCept Oral Suspension contains aspartame, a source of phenylalanine. Before prescribing CellCept Oral Suspension to a patient with PKU, consider the combined daily amount of phenylalanine from all sources, including CellCept.
• Patients should not donate blood during therapy and for at least 6 weeks following discontinuation of CellCept because their blood or blood products might be administered to a female of reproductive potential or a pregnant woman.
• Men should not donate semen during therapy and for 90 days following discontinuation of CellCept.
• CellCept may impact the ability to drive and use machines. Patients should avoid driving or using machines if they experience somnolence, confusion, dizziness, tremor, or hypotension during treatment with CellCept.
• There are no data on the presence of mycophenolate in human milk, or the effects on milk production.

What to do in case of emergency/overdose?

Symptoms of overdose may include:

• leukopenia and neutropenia, and gastrointestinal symptoms such as abdominal pain, diarrhea, nausea, vomiting, and dyspepsia.

Management of overdosage:

• In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.

• Overdose related information is also available online at poisonhelp.org/help.
• In the event that the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services. In the United States, call 911.
• MPA and the phenolic glucuronide metabolite of MPA (MPAG) are usually not removed by hemodialysis.
• However, at high MPAG plasma concentrations (>100 µg/mL), small amounts of MPAG are removed.
• By increasing excretion of the drug, MPA can be removed by bile acid sequestrants, such as cholestyramine.

Can this medicine be used in pregnancy?

• Use of mycophenolate mofetil (MMF) during pregnancy is associated with an increased risk of first trimester pregnancy loss and an increased risk of multiple congenital malformations in multiple organ systems.
• Consider alternative immunosuppressants with less potential for embryofetal toxicity. Risks and benefits of CellCept should be discussed with the pregnant woman.

• 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 REMS website at: www.mycophenolateREMS.com

Can this medicine be used in children?

• Safety and effectiveness have been established in pediatric patients 3 months and older for the prophylaxis of organ rejection of allogenic kidney, heart or liver transplants.
