( 5.9 ) Local Reactions with Rapid Intravenous Administration: Mycophenolate mofetil Intravenous must not be administered by rapid or bolus intravenous injection. ( 5.10 ) Phenylketonurics: Oral suspension contains aspartame. ( 5.11 ) Blood Donation: Avoid during therapy and for 6 weeks thereafter.
( 5.12 ) Semen Donation: Avoid during therapy and for 90 days thereafter. ( 5.13 ) Potential Impairment on Driving and Use of Machinery: Mycophenolate mofetil may affect ability to drive or operate machinery. ( 5.15 )
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. Females of reproductive potential must be made aware of these risks and must be counseled regarding pregnancy prevention and planning.
Avoid use of MMF during pregnancy if safer treatment options are available [see Use in Specific Populations ( 8.1 , 8.3 )].
5.2Lymphoma and Other Malignancies
Patients receiving immunosuppressants, including mycophenolate mofetil, are at increased risk of developing lymphomas and other malignancies, particularly of the skin [see Adverse Reactions ( 6.1 )]. The risk appears to be related to the intensity and duration of immunosuppression rather than to the use of any specific agent. 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 0.4% to 1% of patients receiving mycophenolate mofetil (2 g or 3 g) with other immunosuppressive agents in controlled clinical trials of kidney, heart and liver transplant patients [see Adverse Reactions ( 6.1 )]. The majority of PTLD cases appear to be related to Epstein Barr Virus (EBV) infection. The risk of PTLD appears greatest in those individuals who are EBV seronegative, a population which includes many young children.
In pediatric patients, no other malignancies besides PTLD were observed in clinical trials [see Adverse Reactions ( 6.1 )].
5.3Serious Infections
Patients receiving immunosuppressants, including mycophenolate mofetil, are at increased risk of developing bacterial, fungal, protozoal and new or reactivated viral infections, including opportunistic infections. The risk increases with the total immunosuppressive load. These infections may lead to serious outcomes, including hospitalizations and death [see Adverse Reactions ( 6.1 , 6.2 )]. Serious viral infections reported include:
Polyomavirus-associated nephropathy (PVAN), especially due to BK virus infection
JC virus-associated progressive multifocal leukoencephalopathy (PML), and
Cytomegalovirus (CMV) infections: CMV seronegative transplant patients who receive an organ from a CMV seropositive donor are at highest risk of CMV viremia and CMV disease.
Viral reactivation in patients infected with Hepatitis B and C
COVID-19 Consider dose reduction or discontinuation of mycophenolate mofetil in patients who develop new infections or reactivate viral infections, weighing the risk that reduced immunosuppression represents to the functioning allograft. PVAN, especially due to BK virus infection, is associated with serious outcomes, including deteriorating renal function and renal graft loss [see Adverse Reactions ( 6.2 )]. Patient monitoring may help detect patients at risk for PVAN. PML, which is sometimes fatal, commonly presents with hemiparesis, apathy, confusion, cognitive deficiencies, and ataxia [see Adverse Reactions ( 6.2 )]. In immunosuppressed patients, physicians should consider PML in the differential diagnosis in patients reporting neurological symptoms. The risk of CMV viremia and CMV disease is highest among transplant recipients seronegative for CMV at time of transplant who receive a graft from a CMV seropositive donor. Therapeutic approaches to limiting CMV disease exist and should be routinely provided. Patient monitoring may help detect patients at risk for CMV disease. Viral reactivation has been reported in patients infected with HBV or HCV. Monitoring infected patients for clinical and laboratory signs of active HBV or HCV infection is recommended.
5.4Blood Dyscrasias: Neutropenia and Pure Red Cell Aplasia (PRCA)
Severe neutropenia [absolute neutrophil count (ANC) less than 0.5 x 103/mcL] developed in transplant patients receiving mycophenolate mofetil 3 g daily [see Adverse Reactions ( 6.1 )]. Patients receiving mycophenolate mofetil should be monitored for neutropenia. Neutropenia has been observed most frequently in the period from 31 to 180 days post-transplant in patients treated for prevention of kidney, heart and liver rejection.
The development of neutropenia may be related to mycophenolate mofetil itself, concomitant medications, viral infections, or a combination of these causes. If neutropenia develops (ANC less than 1.3 x 103/mcL), dosing with mycophenolate mofetil should be interrupted or the dose reduced, appropriate diagnostic tests performed, and the patient managed appropriately [see Dosage and Administration ( 2.5 )]. Patients receiving mycophenolate mofetil should be instructed to report immediately any evidence of infection, unexpected bruising, bleeding or any other manifestation of bone marrow depression.
Consider monitoring with complete blood counts weekly for the first month, twice monthly for the second and third months, and monthly for the remainder of the first year. Cases of pure red cell aplasia (PRCA) have been reported in patients treated with mycophenolate mofetil in combination with other immunosuppressive agents. In some cases, PRCA was found to be reversible with dose reduction or cessation of mycophenolate mofetil therapy.
In transplant patients, however, reduced immunosuppression may place the graft at risk.
5.5Gastrointestinal Complications
Gastrointestinal bleeding requiring hospitalization, ulceration and perforations were observed in clinical trials. Physicians should be aware of these serious adverse effects particularly when administering mycophenolate mofetil to patients with a gastrointestinal disease.
5.6Patients with Hypoxanthine-Guanine Phosphoribosyl-Transferase Deficiency (HGPRT)
Mycophenolate mofetil 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 because it may cause an exacerbation of disease symptoms characterized by the overproduction and accumulation of uric acid leading to symptoms associated with gout such as acute arthritis, tophi, nephrolithiasis or urolithiasis and renal disease including renal failure.
5.7Acute Inflammatory Syndrome Associated with Mycophenolate Products
Acute inflammatory syndrome (AIS) has been reported with the use of MMF and mycophenolate products, and some cases have resulted in hospitalization. AIS is a paradoxical p

7.1Effect of Other Drugs on Mycophenolate Mofetil Table 7. Drug Interactions with Mycophenolate
Mofetil that Affect Mycophenolic Acid (MPA) Exposure Antacids with Magnesium or Aluminum Hydroxide Clinical Impact Concomitant use with an antacid containing magnesium or aluminum hydroxide decreases MPA systemic exposure [see Clinical Pharmacology ( 12.3 )], which may reduce mycophenolate mofetil efficacy. Prevention or Management Administer magnesium or aluminum hydroxide containing antacids at least 2h after mycophenolate mofetil administration.
Proton Pump Inhibitors (PPIs) Clinical Impact Concomitant use with PPIs decreases MPA systemic exposure [see Clinical Pharmacology ( 12.3 )], which may reduce mycophenolate mofetil efficacy. Prevention or Management Monitor patients for alterations in efficacy when PPIs are co-administered with mycophenolate mofetil. Examples Lansoprazole, pantoprazole Drugs that Interfere with Enterohepatic Recirculation Clinical Impact Concomitant use with drugs that directly interfere with enterohepatic recirculation, or indirectly interfere with enterohepatic recirculation by altering the gastrointestinal flora, can decrease MPA systemic exposure [see Clinical Pharmacology ( 12.3 )], which may reduce mycophenolate mofetil efficacy.
Prevention or Management Monitor patients for alterations in efficacy or mycophenolate mofetil related adverse reactions when these drugs are co-administered with mycophenolate mofetil. Examples Cyclosporine A, trimethoprim/sulfamethoxazole, bile acid sequestrants (cholestyramine), rifampin as well as aminoglycoside, cephalosporin, fluoroquinolone and penicillin classes of antimicrobials Drugs Modulating Glucuronidation Clinical Impact Concomitant use with drugs inducing glucuronidation decreases MPA systemic exposure, potentially reducing mycophenolate mofetil efficacy, while use with drugs inhibiting glucuronidation increases MPA systemic exposure [see Clinical Pharmacology ( 12.3 )], which may increase the risk of mycophenolate mofetil related adverse reactions.
Prevention or Management Monitor patients for alterations in efficacy or mycophenolate mofetil related adverse reactions when these drugs are co-administered with mycophenolate mofetil. Examples Telmisartan (induces glucuronidation); isavuconazole (inhibits glucuronidation). Calcium Free Phosphate Binders Clinical Impact Concomitant use with calcium free phosphate binders decrease MPA systemic exposure [see Clinical Pharmacology ( 12.3 )], which may reduce mycophenolate mofetil efficacy.
Prevention or Management Administer calcium free phosphate binders at least 2 hours after mycophenolate mofetil. Examples Sevelamer
7.2Effect of Mycophenolate Mofetil on Other Drugs Table 8. Drug Interactions with Mycophenolate
Mofetil that Affect Other Drugs Drugs that Undergo Renal Tubular Secretion Clinical Impact When concomitantly used with mycophenolate mofetil, its metabolite MPAG, may compete with drugs eliminated by renal tubular secretion which may increase plasma concentrations and/or adverse reactions associated with these drugs. Prevention or Management Monitor for drug-related adverse reactions in patients with renal impairment.
Examples Acyclovir, ganciclovir, probenecid, valacyclovir, valganciclovir Combination Oral Contraceptives Clinical Impact Concomitant use with mycophenolate mofetil decreased the systemic exposure to levonorgestrel, but did not affect the systemic exposure to ethinylestradiol [see Clinical Pharmacology ( 12.3 )], which may result in reduced combination oral contraceptive effectiveness. Prevention or Management Use additional barrier contraceptive methods.
Pregnancy and breastfeeding
8.1Pregnancy Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to mycophenolate during pregnancy and those becoming pregnant within 6 weeks of discontinuing mycophenolate mofetil treatment. To report a pregnancy or obtain information about the registry, visit www.mycophenolateREMS.com or call 1-800-617-8191. Risk Summary 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 [see Human Data] .
Oral administration of mycophenolate to rats and rabbits during the period of organogenesis produced congenital malformations and pregnancy loss at doses less than the recommended clinical dose (0.01 to 0.05 times the recommended clinical doses in kidney and heart transplant patients) [see Animal Data]. Consider alternative immunosuppressants with less potential for embryofetal toxicity. Risks and benefits of mycophenolate mofetil should be discussed with the pregnant woman.
The estimated background risk of pregnancy loss and congenital malformations in organ transplant populations is not clear . In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Human Data A spectrum of congenital malformations (including multiple malformations in individual newborns) has been reported in 23 to 27% of live births in MMF exposed pregnancies, based on published data from pregnancy registries.
Malformations that have been documented include external ear, eye, and other facial abnormalities including cleft lip and palate, and anomalies of the distal limbs, heart, esophagus, kidney, and nervous system. Based on published data from pregnancy registries, the risk of first trimester pregnancy loss has been reported at 45 to 49% following MMF exposure. Animal Data In animal reproductive toxicology studies, there were increased rates of fetal resorptions and malformations in the absence of maternal toxicity.
Oral administration of MMF to pregnant rats from Gestational Day 7 to Day 16 produced increased embryofetal lethality and fetal malformations including anophthalmia, agnathia, and hydrocephaly at doses equivalent to 0.015 and 0.01 times the recommended human doses for renal and cardiac transplant patients, respectively, when corrected for BSA. Oral administration of MMF to pregnant rabbits from Gestational Day 7 to Day 19 produced increased embryofetal lethality and fetal malformations included ectopia cordis, ectopic kidneys, diaphragmatic hernia, and umbilical hernia at dose equivalents as low as 0.05 and 0.03 times the recommended human doses for renal and cardiac transplant patients, respectively, when corrected for BSA.

6.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. An estimated total of 1,557 adult patients received mycophenolate mofetil during pivotal clinical trials in the prevention of acute organ rejection. Of these, 991 were included in the three renal studies, 277 were included in one hepatic study, and 289 were included in one cardiac study.
Patients in all study arms also received cyclosporine and corticosteroids. The data described below primarily derive from five randomized, active-controlled double-blind 12-month trials of mycophenolate mofetil in de novo kidney (3) heart (1) and liver (1) transplant patients [see Clinical Studies ( 14.1 , 14.2 , and 14.3 )] . Mycophenolate Mofetil Oral The incidence of adverse reactions for mycophenolate mofetil was determined in five randomized, comparative, double-blind trials in the prevention of rejection in kidney, heart and liver transplant patients (two active-and one placebo-controlled trials, one active-controlled trial, and one active-controlled trial, respectively) [see Clinical Studies ( 14.1 , 14.2 and 14.3 )].
The three de novo kidney studies with 12-month duration compared two dose levels of oral mycophenolate mofetil (1 g twice daily and 1.5 g twice daily) with azathioprine (2 studies) or placebo (1 study) when administered in combination with cyclosporine (Sandimmune ® ) and corticosteroids to prevent acute rejection episodes. One study also included anti-thymocyte globulin (ATGAM ® ) induction therapy. In the de novo heart transplantation study with 12-month duration, patients received mycophenolate mofetil 1.5 g twice daily (n=289) or azathioprine 1.5 to 3 mg/kg/day (n=289), in combination with cyclosporine (Sandimmune ® or Neoral ® ) and corticosteroids as maintenance immunosuppressive therapy.
In the de novo liver transplantation study with 12-month duration, patients received mycophenolate mofetil 1 g twice daily intravenously for up to 14 days followed by mycophenolate mofetil 1.5 g twice daily orally or azathioprine 1 to 2 mg/kg/day intravenously followed by azathioprine 1 to 2 mg/kg/day orally, in combination with cyclosporine (Neoral ® ) and corticosteroids as maintenance immunosuppressive therapy. The total number of patients enrolled was 565.
Approximately 53% of the kidney transplant patients, 65% of the heart transplant patients, and 48% of the liver transplant patients were treated for more than 1 year. Adverse reactions reported in ≥20% of patients in the mycophenolate mofetil treatment groups are presented below. The safety data of three kidney transplantation studies are pooled together. Table 5.

In the three de novo kidney studies, patients receiving 2 g/day of mycophenolate mofetil had an overall better safety profile than did patients receiving 3 g/day of mycophenolate mofetil.
Post-transplant lymphoproliferative disease (PTLD, pseudolymphoma) developed in 0.4% to 1% of patients receiving mycophenolate mofetil (2 g or 3 g daily) with other immunosuppressive agents in controlled clinical trials of kidney, heart and liver transplant patients followed for at least 1 year [see Warnings and Precautions ( 5.2 ) ]. Non-melanoma skin carcinomas occurred in 1.6% to 4.2% of patients, other types of malignancy in 0.7% to 2.1% of patients.
Three-year safety data in kidney and heart transplant patients did not reveal any unexpected changes in incidence of malignancy compared to the 1-year data. In pediatric patients, PTLD was observed in 1.35% (2/148) by 12 months post-transplant. Cytopenias, including leukopenia, anemia, thrombocytopenia and pancytopenia are a known risk associated with mycophenolate and may lead or contribute to the occurrence of infections and hemorrhages [see Warnings and Precautions ( 5.3 )] .
Severe neutropenia (ANC <0.5 x 103/μL) developed in up to 2% of kidney transplant patients, up to 2.8% of heart transplant patients and up to 3.6% of liver transplant patients receiving mycophenolate mofetil 3 g daily [see Warnings and Precautions ( 5.4 ) and Dosage and Administration ( 2
