What Fasturtec is used for
Fasturtec contains rasburicase rys, which is a recombinant urate-oxidase enzyme. Fasturtec is used to prevent or to decrease the high levels of uric acid in your blood that can occur as a result of chemotherapy for cancers of the blood, such as leukemia or lymphoma. Normal amounts of uric acid in the blood are removed by the kidneys. If there are high levels of uric acid in the blood, your kidneys may not be able to remove the excess, and may be damaged. Fasturtec converts uric acid into a substance called allantoin, which is easier for your kidneys to remove.
Your doctor may have prescribed Fasturtec for another reason.
Ask your doctor or pharmacist if you have any questions about why this medicine has been prescribed for you.
Fasturtec is not addictive.
This medicine is available only with a doctor's prescription.

How Fasturtec is given
How much is given

How it is given

If you are given too much (overdose)
