Drug and food interactions

Moderate

baloxavir marboxil food

Applies to: Xofluza (baloxavir marboxil)

GENERALLY AVOID: Coadministration with foods or medications that contain polyvalent cations such as dairy products, calcium-fortified beverages, certain laxatives, antacids, or oral supplements may decrease the plasma concentrations and therapeutic efficacy of baloxavir. The proposed mechanism is chelation of baloxavir by polyvalent cations, forming a complex that is poorly absorbed from the gastrointestinal tract. A significant decrease in baloxavir exposure was observed in monkeys when the prodrug, baloxavir marboxil, was coadministered with calcium, aluminum, magnesium, or iron. However, clinical data in humans are lacking.

When baloxavir marboxil was administered with food, baloxavir peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 48% and 36%, respectively, relative to administration under fasting. These changes are not considered clinically significant.

MANAGEMENT: Baloxavir marboxil may be taken with or without food. However, coadministration with dairy products, calcium-fortified beverages, or polyvalent cation-containing laxatives, antacids, or oral supplements (e.g., calcium, iron, magnesium, selenium, or zinc) should be avoided.

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.
