What else do I need to know?

Due to the chance of allergic reactions, your child should stay in the clinic for observation for 30 to 60 minutes after the medicine is given. There are 3 types of asparaginase. Another type may be given if an allergic reaction occurs.

All caregivers should wear gloves when handling urine, stool, and vomit while your child is receiving the chemotherapy and for
48 hours afterward. Urine, stool, and vomit can be safely disposed of in septic tanks and the sewer system.

Any clothing or bed linens that are contaminated with urine, stool, or vomit should be washed separately from other laundry in hot water and detergent. Anyone handling the contaminated laundry should wear gloves.

The urine will need to be checked at times for glucose (sugar).

You and your child should know the names of all the medicines he or she is taking. Share this information with anyone involved in your child's care.
