Precautions

The US FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for mycophenolate. It includes elements to assure safe use. For additional information: http://www.accessdata.fda.gov/scripts/cder/rems/index.cfm

US BOXED WARNINGS:
EMBRYOFETAL TOXICITY:

Use of this drug during pregnancy is associated with increased risk of pregnancy loss and congenital malformations.
Females of reproductive potential should be counseled regarding pregnancy prevention and planning.

MALIGNANCIES:

This drug is associated with an increased risk for development of lymphoma and other malignancies, particularly of the skin, due to immunosuppression.

SERIOUS INFECTIONS:

This drug is associated with increased susceptibility to bacterial, viral, fungal, and protozoal infections, including opportunistic infections.

ADMINISTRATION WARNINGS:

Only physicians experienced in immunosuppressive therapy and management of organ transplant patients should prescribe this drug.
Patients should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources.
The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient.

Safety and efficacy have not been established in patients younger than 5 years.

Consult WARNINGS section for additional precautions.

Dialysis

Although dialysis may be used to remove the inactive metabolite mycophenolic acid glucuronide, it would not be expected to remove clinically significant amounts of the active moiety mycophenolic acid. This is in large part due to the high plasma protein binding of mycophenolic acid.

Other Comments

Administration advice:

Some manufacturers recommend this drug be taken on an empty stomach and others recommend that it can be taken with or without food if the patient is consistent.
Swallow tablets whole; do not crush, chew, or divide.

General:

Only qualified transplant specialists or healthcare providers experienced in this field should initiate and maintain therapy with this drug.
Mycophenolic acid delayed-release tablets and mycophenolate mofetil (MMF) tablets and capsules should not be used interchangeably without physician supervision because the rate of absorption following the administration of these two products is not equivalent.

Monitoring:

Complete blood counts should be performed weekly during the first month, twice monthly for the second and third month of treatment, then monthly through the first year.

Patient advice:

Patients should be instructed to immediately report any evidence of infection, unexpected bruising, bleeding, or any other manifestation of bone marrow suppression.
