Profile of side effects associated with the immunosuppressive agents is often difficult to establish because of the underlying disease and simultaneous use of many other drugs.
The main side reactions associated with the use of MMF in combination with cyclosporine and glucocorticosteroids to prevent rejection of the renal, cardiac or hepatic graft are diarrhea, leukopenia, sepsis and vomiting; there are also data on the increase in the incidence of certain types of infections, for example, opportunistic infections (see section "Special instructions").
As against the combined immunosuppression in general, and with the use of MMF as a component of the immunosuppressive regimen, there is an increased risk of developing lymphomas and other malignant tumors, especially the skin (see section "Side effect"). In controlled clinical trials, in patients who underwent a kidney, heart or liver transplant and who had been observed for at least 1 year, lymphoproliferative diseases or lymphomas developed in 0.4-1% of patients receiving MMF (at doses of 2 or 3 g / day) in combination with other immunosuppressants . Skin cancer (excluding melanoma) was noted in 1.6-3.2% of patients, malignant neoplasms of other types - in 0.7-2.1% of patients.Three-year data on safety in patients after kidney or heart transplant did not reveal any unexpected changes in the incidence rate of malignant tumors, compared with annual indicators. After liver transplant patients were observed for at least 1 year, but less than 3 years.
The risk of opportunistic infections is increased in all posttransplant patients and increases with an increase in the degree of immunosuppression (see section "Special instructions"). In controlled clinical trials using MMF (2 or 3 g / day) in combination with other immunosuppressants in patients who were observed for 1 year after kidney transplantation (at a dose of 2 g per day), heart and liver, the most frequent infections were candidiasis of the skin and mucous membranes, cytomegalovirus (CMV) infection: CMV viremia / CMV syndrome (13.5%) and infection caused by the herpes simplex virus. After kidney transplantation, sepsis (usually associated with CMV) was more likely to occur in patients receiving MMF than in the control group. In patients receiving MMF at a dose of 3 g, the incidence of sepsis was higher than in patients receiving MMF at a dose of 2 g.
The type of adverse reactions and the frequency of their occurrence in a clinical trial with oral administration of 600 mg / m2MMF 2 times a day in children aged 3 months to 18 years (N = 100) did not differ from those in adult patients who received the drug at a dose of 1 g 2 times a day. However, such adverse reactions as diarrhea, leukopenia, sepsis, infections, anemia were more common (≥10%) in children, especially under the age of 6 years.
Adverse events noted in ≥10% and in 3-10% of patients receiving MMF in combination with cyclosporine and glucocorticosteroids in controlled studies on the prevention of kidney transplant rejection (3 studies, daily dose of 2 and 3 mg), in a controlled trial of heart transplant and in a controlled liver transplantation study.

Cases of progressive multifocal leukoencephalopathy (PML), sometimes fatal, were observed in patients taking MMF. In reports on these cases, there is information about the presence of additional risk factors for the development of PML in patients, including immunosuppressive therapy and impairment of immunity.
In patients taking MMF, there were cases of development of nephropathy associated with VC virus (VC virus-associated nephropathy).This infection can lead to serious consequences, sometimes to the death of a kidney transplant.
Other undesirable reactions observed during the post-marketing use of the drug do not differ from the undesirable reactions recorded in controlled clinical trials.
