How It Works

Irinotecan is an antitumor drug that interferes with how cancer cells multiply. The dose is based on your body size. The type and extent of a cancer determines the exact dose and schedule for using this drug. Irinotecan is an intravenous (IV) drug.

Why It Is Used

Irinotecan is used to treat cancer of the cervix, colon, or rectum. It may also be used to treat non–small-cell lung cancer.

How Well It Works

Irinotecan is an effective antitumor drug for many people. But the type and extent of a cancer determines how effectively this drug slows or stops the growth of cancer cells in the body. Irinotecan is often used in combination with other chemotherapy drugs, making the other drugs more effective than they are by themselves.¹
