Relevance: 02.09.2022 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Baloxavir marboxil should not be taken together with calcium carbonate. Products that contain magnesium, aluminum, calcium, iron, and/or other minerals may interfere with the absorption of baloxavir marboxil and reduce its effectiveness. Talk to your doctor or pharmacist if you have questions on how to take baloxavir marboxil or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

GENERALLY AVOID: Coadministration with polyvalent cation-containing products 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.

MANAGEMENT: Concurrent administration of baloxavir marboxil with polyvalent cation-containing laxatives, antacids, or oral supplements (e.g., aluminum, calcium, iron, magnesium, selenium, zinc) should generally be avoided.
