Introduction: Capecitabine is an orally bioavailable prodrug of the chemotherapeutic agent, fluorouracil. Fluorouracil is converted to several active metabolites that induce a cytotoxic effect. Capecitabine toxicity can be life-threatening with a delayed presentation from ingestion. An oral antidote, uridine triacetate, exists but requires the administration of 20 total doses over a course of five days. Case report: In this report, we describe a case where timely coordination with a clinical toxicology laboratory was utilized to drive clinical decision making and management. Two children were brought to the emergency department shortly after suspected capecitabine ingestion. Management and outcome: Patients were admitted to the hospital and started on uridine triacetate. Real-time comprehensive toxicology testing of the children's blood was used to rule out capecitabine toxicity and prevent several unnecessary days of hospitalization and doses of antidote. Patients were discharged safely. Discussion: Real-time comprehensive toxicology testing on a patient's blood may be a valuable resource in ruling out or confirming toxic exposure in accidental pediatric ingestion of chemotherapeutic agents like capecitabine when performed in a timely manner.
