Rasburicase can cause a severe allergic reaction. If you develop new symptoms such as chest pain, trouble breathing, severe dizziness, a rash, or hives, stop using rasburicase and seek immediate medical attention. Do not restart rasburicase if a severe allergic reaction has occurred. Consult your doctor or pharmacist for more details.
Do not use rasburicase if you have a metabolic condition called glucose-6-phosphate dehydrogenase (G6PD) deficiency because it can severely damage your red blood cells, leading to anemia (hemolysis). If you are of African or Mediterranean descent, you may be at higher risk for G6PD deficiency and should be tested to see if you have this condition before starting rasburicase.
Rasburicase can cause a condition that affects the ability of your red blood cells to carry oxygen (methemoglobinemia). Do not restart rasburicase if this effect occurs. Consult your doctor for more details.
Rasburicase can interfere with accurate measurements of uric acid in the blood, resulting in falsely low levels. Be sure to tell all lab personnel that you are using rasburicase.
Rasburicase is used for:
Preventing high blood levels of uric acid from occurring in patients with certain types of cancer (eg, leukemia, lymphoma, solid malignant tumors) who are receiving cancer chemotherapy treatment.
Rasburicase is a urate-oxidase enzyme. When chemotherapy is given, cancer cells are destroyed, releasing large amounts of uric acid into the blood. Rasburicase works by allowing uric acid to be more easily removed from the body by the kidneys.
Do NOT use rasburicase if:
- you are allergic to any ingredient in rasburicase
- you have a history of blood problems such as methemoglobinemia (a bluish discoloration to the skin and mucous membranes) or hemolysis after receiving rasburicase
- you have a metabolic condition called G6PD deficiency
Contact your doctor or health care provider right away if any of these apply to you.
