How does this medication work? What will it do for me?
Irinotecan belongs to the group of cancer-fighting medications known as antineoplastics. It kills cancer cells by interfering with the genetic material DNA, which is necessary for their growth and reproduction. Irinotecan is usually used in combination with other medications to treat colon or rectal cancer.
Your doctor may have suggested this medication for conditions other than the ones listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are receiving this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
How should I use this medication?
The recommended dose and dosing schedule of irinotecan varies according to the stage of therapy, the stage of cancer, the response to therapy, and the person's body size. It is injected into a vein through a specially prepared site on the skin. The appropriate dose of irinotecan is usually given by an infusion over a period of about 90 minutes. The dose is usually given once weekly for 4 weeks, followed by a 2-week rest period.
This cycle is repeated until it is determined that treatment is completed. Very careful handling of this medication is required. Irinotecan is always used under the supervision of a doctor in a hospital or similar setting with access to sterile equipment for preparation.
As well as interfering with the genetic material DNA of cancer cells, irinotecan can interfere with some of your normal cells. This can cause a number of side effects such as hair loss and mouth sores. Irinotecan can cause nausea and vomiting, but it is important to keep using this medication.
Your doctor, nurse, or pharmacist can advise you on how to reduce the effects of nausea and vomiting. Keep track of any side effects and report them to your doctor as suggested in the section, "What side effects are possible with this medication?"
