This medication is used to prevent high blood levels of uric acid from occurring in children with cancer (such as 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.
How to use Elitek Vial
This medication is given by injection into a vein as directed by your doctor, usually over 30 minutes. 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.
