Irinotecan is a topoisomerase I inhibitor used in the treatment of colorectal cancer.

- Metastatic colorectal cancer: improves survival when combined with fluoropyrimidine‑based regimens. - Colorectal cancer (adjuvant setting): reduces risk of recurrence after surgical resection. - Colorectal cancer (first‑line therapy): administered with leucovorin and 5‑FU as part of the FOLFIRI regimen.

Irinotecan may cause a range of adverse reactions, some of which are common and others that are serious or rare.

Common Side Effects: - Neutropenia: reduced white blood cell count increasing infection risk. - Diarrhea: may be severe and require supportive care. - Nausea and vomiting: often managed with anti‑emetics. - Fatigue: generalized tiredness during treatment.

Serious or Rare Side Effects: - Febrile neutropenia: fever with low neutrophils requiring urgent medical attention. - Severe colitis: intense inflammation of the colon that can be life‑threatening. - Allergic reactions: including rash, bronchospasm, or anaphylaxis. - Hepatotoxicity: elevated liver enzymes indicating liver injury.

Prior to initiating therapy, clinicians should assess patient‑specific factors and monitor for potential complications.

- Monitor blood counts: watch for neutropenia and adjust treatment as needed. - Assess liver function: dose adjustments may be required in hepatic impairment. - Maintain adequate hydration: helps reduce the severity of diarrhea. - Avoid strong CYP3A4 inhibitors: concurrent use can increase irinotecan exposure. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Irinotecan can interact with other medicines, affecting its safety and efficacy.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole): may raise irinotecan plasma levels. - CYP3A4 inducers (e.g., rifampin): can reduce therapeutic effect. - Concurrent myelosuppressive agents: increase risk of severe bone‑marrow suppression.

Moderate Interactions (Monitor Closely): - Warfarin: may enhance anticoagulant effect, requiring INR monitoring. - NSAIDs: can exacerbate gastrointestinal toxicity. - Other antineoplastic drugs: may require dose adjustments and close observation.
