Management of acute cancer treatment-induced diarrhea

To describe the dietary and pharmacologic management of acute CTID.

Primary and secondary literature, and clinical experience.

When dietary strategies do not work, or when patients present with grade 3/4 diarrhea, pharmacologic intervention is required. First-line therapy should be initiated quickly with loperamide or diphenoxylate/atropine in recommended doses. Somatostatin analogues are effective as second-line therapy or as first-line therapy for patients with grade 3/4 diarrhea.

Oncology nurses should strive to match treatment with the severity of symptoms of CTID. Whatever therapy is chosen, the goal must be to quickly control this debilitating and potentially life-threatening side effect so that primary chemotherapy and/or radiation therapy may be resumed and completed.
