Interactions between your drugs

Moderate

mycophenolic acid ropeginterferon alfa-2b

Applies to: mycophenolic acid and ropeginterferon alfa-2b

GENERALLY AVOID: Coadministration with other myelosuppressive agents may potentiate the hematologic toxicities of ropeginterferon alfa-2b. Decreased peripheral blood counts have been reported in patients receiving interferon alfa products, including ropeginterferon alfa-2b. In two open label trials consisting of 178 patients receiving ropeginterferon alfa-2b monotherapy (dosed every 2 to 4 weeks) for the treatment of polycythemia vera, 80% of whom were exposed for 12 months or longer, leukopenia occurred in 20% of patients and thrombocytopenia in 19% of patients. Leukopenia, thrombocytopenia and anemia of grade 3 or higher occurred in 2%, 2% and 1% of patients, respectively. Moreover, infections occurred in 48% of patients, while serious infections occurred in 8% of patients.

MANAGEMENT: Concomitant use of ropeginterferon alfa-2b with other myelosuppressive agents should be avoided when possible. Otherwise, close clinical and laboratory monitoring are advised. Complete blood counts should be performed at baseline, during titration, and every 3 to 6 months or more frequently as clinically indicated during the maintenance phase.

Drug and food interactions

Moderate

mycophenolic acid food

Applies to: 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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
