Interactions between your drugs
yellow fever vaccine mycophenolic acid
Applies to: yellow fever vaccine and Myfortic (mycophenolic acid)
CONTRAINDICATED: The administration of live, attenuated viral or bacterial vaccines during immunosuppressant or intense antineoplastic therapy may be associated with a risk of disseminated infection due to enhanced replication of vaccine virus or bacteria in the presence of diminished immune competence. Patients may be immunosuppressed if they have recently received or are receiving alkylating agents, antimetabolites, radiation, some antirheumatic agents, high dosages of corticosteroids or adrenocorticotropic agents (e.g., greater than or equal to 2 mg/kg/day or 20 mg/day of prednisone or equivalent for 14 consecutive days or more), or long-term topical or inhaled corticosteroids. These patients may also have increased adverse reactions and decreased or suboptimal immunologic response to vaccines.
MANAGEMENT: In general, live attenuated vaccines should not be used in patients receiving immunosuppressive therapy or cancer chemotherapy. Vaccination should be deferred until after such therapy is discontinued and immune function has been restored, usually 4 to 12 weeks after stopping immunosuppressive therapy. A longer waiting period may be necessary following treatment with agents that have a prolonged elimination half-life (e.g., leflunomide, teriflunomide). In most situations, patients who have recently been vaccinated with a live vaccine should not initiate treatment with immunosuppressive therapy for at least 2 weeks (possibly longer in some cases). Current local immunization guidelines and prescribing information for individual vaccines and immunosuppressive agents should be consulted for more specific recommendations. Vaccines may generally be administered to patients receiving corticosteroids as replacement therapy (e.g., for Addison's disease).

Drug and food interactions
mycophenolic acid food
Applies to: Myfortic (mycophenolic acid)
ADJUST DOSING INTERVAL: Administration of enteric coated mycophenolic acid with meals may alter its pharmacokinetics relative to administration in the fasting state. When mycophenolic acid 720 mg was administered with a high-fat meal, there was a 33% decrease in the peak plasma concentration (Cmax); a 3.5-hour increase in delay time for the rise of plasma mycophenolic acid; and a 5-hour delay in the time to reach peak plasma concentration (Tmax). However, no effect was observed on the systemic exposure of mycophenolic acid.
MANAGEMENT: To avoid variability in drug absorption between doses, enteric coated formulations of mycophenolic acid should be taken on an empty stomach, one hour before or two hours after food intake. The tablets should be swallowed whole and not crushed, chewed or divided in order to maintain the integrity of the enteric coating.
