Why is this medication prescribed?

Irinotecan is used alone or in combination with other medications to treat colon or rectal cancer (cancer that begins in the large intestine). Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It works by stopping the growth of cancer cells.

How should this medication be used?

Irinotecan comes as a liquid to be given over 90 minutes intravenously (into a vein) by a doctor or nurse. It is usually given not more often than once a week, according to a schedule that alternates one or more weeks when you receive irinotecan with one or more weeks when you do not receive the medication. Your doctor will choose the schedule that will work best for you.

Your doctor may need to delay your treatment and adjust your dose if you experience certain side effects. Be sure to tell your doctor how you are feeling during your treatment with irinotecan.

Your doctor may give you medication to prevent nausea and vomiting before you receive each dose of irinotecan. Your doctor may also give you other medication(s) to prevent or treat other side effects.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

Are there other uses for this medicine?
