Interactions between your drugs

Moderate

didanosine mycophenolate mofetil

Applies to: didanosine and CellCept (mycophenolate mofetil)

ADJUST DOSING INTERVAL: Coadministration with antacids may decrease the oral bioavailability of mycophenolic acid. The exact mechanism of interaction is unknown but may involve chelation with polyvalent ions in antacids or enhanced drug solubility induced by an increase in gastric pH, or both. The interaction has been reported with magnesium/aluminum-containing antacids.

MANAGEMENT: Patients treated with oral mycophenolic acid who require an antacid or antacid-containing preparation (e.g., didanosine buffered tablets or pediatric oral solution) should separate the administration times of the medications by at least two hours.

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.
