Interactions between your drugs
nafcillin DOXOrubicin liposomal
Applies to: Nallpen (nafcillin) and Doxil (doxorubicin liposomal)
GENERALLY AVOID: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of doxorubicin, which is primarily metabolized by the isoenzyme. One group of investigators reported a nearly 60% increase in the plasma clearance of doxorubicin in patients receiving barbiturates compared to those not receiving barbiturates. Reduced therapeutic effects of doxorubicin may occur.
MANAGEMENT: Concomitant use of doxorubicin with CYP450 3A4 inducers should generally be avoided, particularly potent ones like carbamazepine, enzalutamide, lumacaftor, mitotane, phenobarbital, phenytoin, primidone (partially metabolized to phenobarbital), rifamycins, and St. John's wort. Close monitoring for potentially reduced efficacy of doxorubicin is recommended if coadministration is required.

Drug and food interactions
nafcillin food
Applies to: Nallpen (nafcillin)
ADJUST DOSING INTERVAL: Certain penicillins may exhibit reduced gastrointestinal absorption in the presence of food. The therapeutic effect of the antimicrobial may be reduced.
MANAGEMENT: The interacting penicillin should be administered one hour before or two hours after meals. Penicillin V and amoxicillin are not affected by food and may be given without regard to meals.
