“…Alopecia secondary to 5‐FU toxicosis have not been previously reported in dogs. This is an intriguing finding because in humans, 5‐FU has been shown to induce alopecia less frequently than other chemotherapy agents when administered systemically 20 . Discussions with a veterinary dermatologist and oncologist have affirmed that there are currently no reported cases of alopecia affiliated with 5‐FU administration in domestic animals.…”

Background 5‐Fluorouracil (5‐FU) cream is a common human topical chemotherapy agent with potentially fatal neurotoxic effects on dogs if accidentally ingested. There are seldom reports in veterinary literature describing the successful outcome of intervention after accidental ingestion of 5‐FU cream. Case Summary A 9‐month‐old spayed female labradoodle presented 14 h after ingesting an unknown amount of 40 g tube of Efudex cream (5% 5‐FU). The dog presented in status epilepticus, which was managed with benzodiazepines and levetiracetam in conjunction with induced coma and mechanical ventilation. No further seizure activity occurred throughout the ensuing 5 days of hospitalisation; however, myelosuppression was featured. The dog was discharged home after 5 days of hospitalisation. Three days post discharge, the dog was noted to develop focal alopecia around the eyes and temporal region. 14 days after discharge, the alopecia progressed to a majority of the head and body. Conclusion To the authors' knowledge, this is the first report that documents the enduring adverse effects of 5‐FU cream after survival of the initial episode, including an earlier onset of myelosuppression and diffuse alopecia. Successful treatment of accidental 5‐FU ingestion is possible several hours after the initial event with minimal long‐term consequences.
