What is irinotecan and what is it used for?
Irinotecan is a chemotherapy medicine used to treat cancers where tumor cells rely on DNA replication. It is commonly used for certain colorectal cancers and may be used in other solid tumors depending on local treatment guidelines.
How does irinotecan work?
Irinotecan targets the DNA replication process by inhibiting topoisomerase I, an enzyme that helps unwind and manage DNA strands during cell division. When topoisomerase I is inhibited, DNA damage builds up in dividing cancer cells, which can lead to cell death.
How is irinotecan given?
Irinotecan is administered by health-care professionals as an intravenous (IV) infusion, typically as part of a chemotherapy regimen rather than as a stand-alone treatment.
What side effects are patients most likely to ask about?
Irinotecan is associated with chemotherapy-related side effects. Patients commonly ask clinicians about diarrhea and other gastrointestinal effects, lowered blood counts, nausea, fatigue, and infection risk. One of the most clinically important adverse effects to monitor for is diarrhea, which clinicians manage with supportive care and, when appropriate, antidiarrheal medicines.
What should patients know about diarrhea and how it’s managed?
Diarrhea with irinotecan can be serious and needs prompt treatment. The key is fast reporting to the oncology team so it can be managed early, since dehydration and complications can develop quickly if diarrhea is not treated.
Are there important drug interactions or precautions?
Because irinotecan is processed by the liver, some medicines that affect liver metabolism can change how irinotecan works in the body. Patients should tell their clinicians about all prescription drugs, over-the-counter products, and supplements before starting treatment.
