The following adverse events were observed in two studies of the safety of mycophenolic acid and MMF in 423 patients with a recently transplanted kidney who had not received previous maintenance therapy (patients with a kidney transplant de novo), and in 322 patients with kidney transplant who had previously received maintenance therapy. The incidence of adverse events was similar in both groups of patients.
When using mycophenolic acid in combination with cyclosporine and glucocorticosteroids, undesirable phenomena such as leukopenia (19.2%) and diarrhea (23.5%) were very often (≥ 10%).
In elderly patients, the risk of side effects is generally higher due to immunosuppression.
Malignant neoplasms. In patients receiving immunosuppressive therapy with several drugs, including IFC, the risk of developing lymphomas and other neoplasms, in particular, of the skin, is increased.During the study, malignant tumors developed against the background of mycophenolic acid at the following frequency: lymphoproliferative diseases or lymphomas developed in two patients with a renal transplant de novo (0.9%) and in two patients (1.3%) with a transplanted kidney who received maintenance therapy for up to 1 year; Non-melanoma skin carcinomas developed in 0.9% with a renal transplant de novo and 1.8 % patients with kidney transplant who had previously received maintenance therapy with mycophenolic acid for up to 1 year; other malignant neoplasms developed in 0.5% of patients with a renal transplant de novo and 0.6% of patients with kidney transplant who received maintenance therapy.
Infectious diseases (opportunistic infections). In patients with recent transplanted kidney that received mycophenolic acid for 1 year as part of complex immunosuppressive therapy, the most frequently observed cytomegalovirus (CMV) infection, candidiasis and infection caused by the herpes simplex virus. In the course of studies, it was shown that CMV infection (confirmedserological viremia, or clinical data) was observed at a rate of 21.6% in patients with a recently transplanted kidney and 1.9% in patients with a stable graft functioning with prolonged maintenance therapy.
Other undesirable phenomena
Below are the undesirable events detected with mycophenolic acid at a dose of 1440 mg / day for 12 months in combination with a cyclosporine microemulsion and glucocorticosteroids in two clinical studies in patients with a kidney transplant de novo and in patients with kidney transplant who received previous maintenance therapy. These phenomena had a possible or probable cause-and-effect relationship with the administration of mycophenolic acid. Undesirable phenomena are given in accordance with the classification of organs and systems for MedDRA (medical dictionary of the terminology of regulatory activities) and listed by frequency. The frequency of unwanted reactions is estimated as follows: very often ≥ 10%; often ≥ 1% and <10%; infrequently ≥ 0,1 % and <1%; rarely ≥ 0.01% and <0.1%; very rarely <0.01%, including individual messages.

Disorders from the gastrointestinal tract
Very often: diarrhea.

* this undesirable phenomenon was registered only in one patient out of 372. The profile of adverse events was not different in patients with a transplanted kidney de novo and in patients who previously received maintenance therapy, but the incidence of adverse events was lower in the second group.
The following are undesirable phenomena revealed during post-marketing observations (the frequency is unknown)
Disturbances from the skin and subcutaneous tissues: rash.
Side effects, observed against the background of the use of mycophenolic acid derivatives ("class effects"):
Infectious and parasitic diseases: severe current, sometimes life-threatening infectious diseases (in some cases, with a fatal outcome), including meningitis, infective endocarditis, tuberculosis, atypical infections caused by mycobacteria. The development of poliomavirus nephropathy (especially associated with VC virus) has been reported.
With the use of mycophenolate mofetil, cases of development of progressive multifocal leukoencephalopathy associated with JCa virus, in some cases with a fatal outcome.
Violations from the blood and lymphatic system: agranulocytosis, neutropenia, pancytopenia. When using mycophenolic acid derivatives in combination with other immunosuppressants, cases of development partial red cell aplasia of the bone marrow.
