FDA warns — Pet Illness and Death from Human Cancer Medication

FDA is warning about the possibility of illness or death in pets exposed to the topical cancer drug fluorouracil cream USP 5% (5-FU). The agency cautioned pharmacists, health care providers, veterinarians, and pet owners that it has received reports of five dogs that became sick and died after accidentally ingesting the cream. People who use the drug should use care when storing and applying the drug if they are in a household with pets, FDA said, noting that even minute amounts can be dangerous for pets. FDA has not received any reports involving cats; however, they are also expected to be sensitive to the drug. The cream may also be marketed under the brand names Carac, Effudex, and Fluoroplex.
