What is Voraxaze?

Voraxaze (glucarpidase) is used in patients who develop kidney failure while receiving high doses of methotrexate (a chemotherapy drug).

Voraxaze is an enzyme that breaks down methotrexate in the body so the drug can be easily eliminated when the kidneys are not working properly.

Voraxaze may also be used for purposes not listed in this medication guide.
