Veterinary notes and prevention
Cats lack the enzyme needed to metabolise paracetamol safely, resulting in methaemoglobinaemia and liver damage. Acetylcysteine is the main antidote.
Prepare the information your vet needs
- For Paracetamol / Acetaminophen, report the exposure route: Given by well-meaning owners, or dropped tablets eaten from the floor. Tell the clinic the time, possible amount and your pet's species and approximate weight.
- Photograph the packaging, ingredient list or plant if safe. Do not handle contaminated material without protection or delay the call to identify it perfectly.
- Keep other animals away from the source. An animal may appear normal before signs develop; do not wait for symptoms or calculate a home 'safe dose'.
- Follow the clinic's transport instructions. Do not give food, medicines or home remedies unless instructed, and take packaging with you if available.
