Interactions between your drugs

Major

nevirapine zanubrutinib

Applies to: Viramune XR (nevirapine) and zanubrutinib

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with potent inducers of CYP450 3A4 may significantly decrease the plasma concentrations of zanubrutinib, which is primarily metabolized by the isoenzyme. When zanubrutinib was coadministered with multiple doses of the potent CYP450 3A4 inducer rifampin, zanubrutinib peak plasma concentration (Cmax) and systemic exposure (AUC) decreased 92% and 93%, respectively, in healthy volunteers. Reduction in zanubrutinib plasma concentration may lead to reduced zanubrutinib efficacy.

MANAGEMENT: Due to the potential for reduced pharmacologic effects, concomitant use of zanubrutinib with potent CYP450 3A4 inducers should generally be avoided.

Drug and food interactions

zanubrutinib food

Applies to: zanubrutinib

Grapefruit juice and Seville orange juice can increase the blood levels of zanubrutinib.

You may also be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts.
