Treatment should be initiated and maintained by appropriately qualified transplant specialists. Posology Adults Renal transplant Treatment should be initiated within 72 hours following transplantation. The recommended dose in renal transplant patients is 1 g administered twice daily (2 g daily dose).

Cardiac transplant Treatment should be initiated within 5 days following transplantation. 5 g administered twice daily (3 g daily dose). Hepatic transplant Treatment of intravenous mycophenolate mofetil should be administered for the first 4 days following hepatic transplant, with oral mycophenolate mofetil initiated as soon after this as it can be tolerated.

5 g administered twice daily (3 g daily dose). Paediatric population (1 to 18 years) The paediatric dosing information in this section applies to all oral formulations within the range of mycophenolate mofetil products, as appropriate.

Different oral formulations should not be substituted without clinical supervision. 3 The recommended mycophenolate mofetil initial dose for paediatric renal, cardiac and hepatic transplant patients is 600 mg/m2 (of body surface area (BSA)), administered orally, twice daily (initial total daily dose not to exceed 2 g, or 10 ml of an oral suspension (1 g/5 ml)).

The dose and product form should be individualised based on clinical assessment. If the recommended initial dose is well tolerated but does not achieve clinically adequate immunosuppression in paediatric cardiac and hepatic transplant patients, the dose can be increased to 900 mg/m2 BSA twice daily (maximum total daily dose of 3 g, or 15 ml of an oral suspension (1 g/5 ml)).

The recommended maintenance dose for paediatric renal transplant patients remains at 600 mg/m2 twice daily (maximum total daily dose of 2 g or 10 ml of an oral suspension (1 g/5 ml)). 25 m2 due to the increased risk of choking. 5 g daily dose).

5 m2 may be prescribed mycophenolate mofetil capsules or tablets at a dose of 1 g twice daily (2 g daily dose). 8) compared with adults, temporary dose reduction or interruption may be required; these will need to take into account relevant clinical factors including severity of reaction.

5 g twice a day for cardiac or hepatic transplant patients is appropriate for the elderly. 73 m2), outside the immediate post-transplant period, doses greater than 1 g administered twice a day should be avoided. These patients should also be carefully observed.

1%) were among the most common and/or serious adverse reactions associated with the administration of mycophenolate mofetil in combination with ciclosporin and corticosteroids. 4). Tabulated list of adverse reactions The adverse reactions from clinical trials and post marketing experience are listed in Table 1, by MedDRA system organ class (SOC) along with their frequencies.

The corresponding frequency category for each adverse reaction is based on the following convention: very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000) and not known (cannot be estimated from the available data).

Due to the large differences observed in the frequency of certain adverse reactions across the different transplant indications, the frequency is presented separately for renal, hepatic and cardiac transplant patients.

8). The risk appears to be related to the intensity and duration of immunosuppression rather than to the use of any specific agent. As general advice to minimise the risk for skin cancer, exposure to sunlight and ultraviolet (UV) light should be limited by wearing protective clothing and using a sunscreen with a high protection factor.

8). Such infections include latent viral reactivation, such as hepatitis B or hepatitis C reactivation and infections caused by polyomaviruses (BK virus associated nephropathy, JC virus associated progressive multifocal leukoencephalopathy PML).

Cases of hepatitis due to reactivation of hepatitis B or hepatitis C have been reported in carrier patients treated with immunosuppressants. These infections are often related to a high total immunosuppressive burden and may lead to serious or fatal conditions that physicians should consider in the differential diagnosis in immunosuppressed patients with deteriorating renal function or neurological symptoms.

Mycophenolic acid has a cytostatic effect on B- and Tlymphocytes, therefore an increased severity of COVID19 may occur, and appropriate clinical action should be considered. There have been reports of hypogammaglobulinaemia in association with recurrent infections in patients receiving mycophenolate mofetil in combination with other immunosuppressants.

In some of these cases switching mycophenolate mofetil to an alternative immunosuppressant resulted in serum IgG levels returning to normal. Patients on mycophenolate mofetil who develop recurrent infections should have their serum immunoglobulins measured.

In cases of sustained, clinically relevant hypogammaglobulinaemia, appropriate clinical action should be considered taking into account the potent cytostatic effects that mycophenolic acid has on T- and B-lymphocytes. There have been published reports of bronchiectasis in adults and children who received mycophenolate mofetil in combination with other immunosuppressants.
