Human & experimental toxicology

A combination of pentobarbital and phenytoin is used as a veterinary euthanasia drug. Because of its lethal effect, this study described pentobarbital-phenytoin combination veterinary drug human exposures reported to Texas poison centers during 2000-2015. Of 66 exposures, 73% involved female and 27% male patients. ⋯ This study found few pentobarbital-phenytoin combination veterinary drug exposures were reported to Texas poison centers during a 16-year period. Although meant to be administered intravenously, the most common exposure routes were ocular and ingestion. Many of the exposures appeared to be unintentional and occurred at the workplace.
