About Rasburicase

Rasburicase is given to decrease uric acid in the blood. High levels of uric acid in the blood may be caused by certain cancer medicines. Too much uric acid may cause gout attacks or kidney stones. Patients receiving anticancer therapy that results in tumor lysis syndrome sometimes require rasburicase. This medicine may be given in the clinic or hospital.

Before starting rasburicase, patients may be tested for low levels of an enzyme called G6PD. A G6PD deficiency can cause break down of red blood cells with some medicines. Rasburicase should not be used in patients with G6PD deficiency.

Rasburicase is usually given once a day. Patients will be monitored for signs of an allergic reaction.
