What is asparaginase?
Asparaginase (also called Erwinia Chrysanthemi or Erwinaze®) is a medicine used to treat leukemia. It is given as a substitute for PEGaspargase when an allergic reaction occurs.
It is a clear liquid given into a vein over 30 minutes to one (1) hour, called an IV infusion (in FEW zhen). It is sometimes given as an injection into a muscle (IM).
Asparaginase can pose a health hazard to caregivers. All caregivers should take safety precautions while giving this drug. For 48 hours after this drug is given, the patient’s body fluids can contain the drug. During that 48-hour period, caregivers should follow safety guidelines when handling the patient’s vomit, blood, urine, and bowel movements, including diapers. These guidelines include wearing gloves when cleaning up body fluids. For a complete list of safety precautions, see “Do you know… Protecting caregivers from drug hazards.”

Special instructions for asparaginase
- The nurse will monitor you for one (1) hour after the asparaginase injection for symptoms of an allergic reaction. You should not leave the hospital during this time.
- If you have swelling, pain, redness, or warmth at the injection site, report it right away to the doctor or nurse.
- You may bleed more easily. Avoid injury and use a soft tooth brush.
- You will need to check sugar (glucose) levels in the urine when you are receiving asparaginase. Call the clinic right away to tell the nurse if the urine sugar is greater than 1+. If the urine sugar is less than or equal to 1+, tell the doctor or nurse at the next clinic visit.
- If the urine test shows sugar in the urine, you may need to check blood sugar levels at home. The nurse will teach you how to check your blood sugar at home. Also, you may need insulin to help control the blood sugar level.
- If you feel more thirsty than normal or if you are urinating more often than normal, tell the doctor or nurse right away.
