Glucarpidase is used to prevent harmful effects of methotrexate (Rheumatrex, Trexall) in patients with kidney disease who are receiving methotrexate to treat certain types of cancer. Glucarpidase is in a class of medications called enzymes. It works by helping to break down and remove methotrexate from the body.
Glucarpidase comes as a powder to be mixed with liquid and injected intravenously (into a vein). It is usually given over 5 minutes as a one-time dose. Glucarpidase is given along with leucovorin (another medication used to prevent harmful effects of methotrexate) until laboratory tests show treatment is no longer needed.
