Edit list (add/remove drugs)

Interactions between your drugs

Moderate

modafinil osimertinib

Applies to: modafinil and osimertinib

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of osimertinib, which has been shown in vitro to be primarily metabolized by the isoenzyme. Reduced therapeutic efficacy of osimertinib may occur. However, no pharmacokinetic data are available from drug interaction studies.

MANAGEMENT: The potential for diminished pharmacologic effects of osimertinib should be considered during coadministration with CYP450 3A4 inducers. Alternative treatments may be required if an interaction is suspected.

Drug and food interactions

Minor

modafinil food

Applies to: modafinil

Administration with food may delay the absorption of modafinil (the racemate) and armodafinil (the R-enantiomer) without significantly affecting their overall bioavailability. According to the product labeling, modafinil's absorption may be delayed by approximately one hour if taken with food. Similarly, the time to reach peak plasma concentration (Tmax) of armodafinil may be delayed by approximately 2 to 4 hours in the fed state.

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.
