This medication is used to prevent high blood levels of uric acid from occurring in children with cancer (e.g., leukemia, lymphoma, solid malignant tumors) who are about to receive cancer chemotherapy treatment. When chemotherapy is given, cancer cells are destroyed, releasing large amounts of uric acid into the bloodstream. This medication allows uric acid to more easily be removed from the body by the kidneys.

It is important to receive each dose as scheduled. If you miss a dose, contact your doctor immediately to establish a new schedule.

This medication is given by injection into a vein, usually over 30 minutes, or as directed by your doctor. Rasburicase is given once a day for 5 days. Timing of cancer chemotherapy and rasburicase doses is important. Chemotherapy is usually started 4 to 24 hours after the first dose of rasburicase. Fluids are also given into the vein with this medication to help decrease your uric acid levels.

Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with them first. Tell the doctor of all prescription and nonprescription medication you may use, especially: allopurinol.
