Did your patient just ingest a toxic amount of acetaminophen (commonly called paracetamol in other countries)? Acetaminophen toxicosis is commonly seen in dogs and cats, and can result in liver failure, keratoconjunctivitis sicca (KCS), oxidative injury, methemoglobinemia, and Heinz body anemia. In dogs, the toxic dose is > 100 mg/kg, while in ferrets and cats, the toxic dose is as little as 10 mg/kg. This VetGirl podcast reviews all you need to know about acetaminophen toxicity. Thankfully, this toxicity has an antidote, n-acetylcysteine (NAC).
