Toxic Warning! Human chemotherapy cream is fatal to pets. Hear from Eric N. Glass, MS, DVM, DACVIM from Red Bank Veterinary Hospitals about how Fluorouracil, also known as 5-FU, is fatal to pets. Fluorouracil, a chemotherapeutic ointment, is used for skin cancers such as superficial basal cell carcinoma, or actinic keratosis and goes by brand names of 5-FU include Fluoroplex®, Efudex® and Carac®. This ointment is applied to the affected skin and works by preventing synthesis of proteins in rapidly dividing cells, like tumor cells, which cause death of the cancer.
Unfortunately, most prescribing physicians do not know to warn patients of the risk associated with 5-FU to household pets. Additionally, there is absolutely NO warning on the product packaging to keep the medication out of the reach of pets.
