Fluorouracil cream (USP 5%), used to treat actinic keratoses and basal cell carcinoma, can be deadly when accidentally ingested by pets, the FDA warned on Wednesday.

Five dogs have reportedly died after ingesting the cream. While the agency has not received reports of cat illness or death, it notes: "If an owner applies fluorouracil cream to an afflicted area and touches their cat, the cat may accidentally ingest the medication when grooming itself and suffer adverse events."

When prescribing fluorouracil cream, clinicians should advise patients to take steps to avoid pet exposure, including safe medication storage and prompt cleaning or disposal of applicators. Providers may also advise patients to cover any skin areas that have been treated.
