About Irinotecan

Irinotecan is a type of chemotherapy. It works by stopping or slowing the growth cells. This medicine may be given in the clinic, hospital, or at home. The schedule and dose depends on the type of cancer, the child’s age, and method of administration.

Irinotecan by IV can cause tissue damage if it leaks from the vein. Patients may have irritation at the IV site. Let a caregiver know if there is burning during administration.

A genetic test may be performed to see how well the patient’s enzymes function. If a patient breaks down irinotecan more slowly, a lower dose of the medicine may be given.

Patients will have regular blood draws to check blood counts and monitor liver and kidney function.
