Is Acetaminophen / paracetamol toxic to cats & dogs?

Also known as: Tylenol / cold & flu medicine / fever reducers

🚑 What to do right after ingestion

Ingestion is an immediate emergency (no safe dose in cats): decontamination plus N-acetylcysteine antidote — the earlier the better.

Toxicity notes

Cats can barely metabolize it — a single 500mg tablet is lethal; toxic doses in dogs are low too. The most classic household poisoning: owners giving human medicine to a sick pet.

Poisoning symptoms

  • • Bluish/brown gums
  • • Labored breathing
  • • Facial swelling
  • • Vomiting
  • • Profound lethargy

Symptoms can be delayed (e.g. onion/garlic-induced hemolysis may take days) — a pet looking fine right now is no reason to relax.

FAQ

How much causes poisoning?

Cats can barely metabolize it — a single 500mg tablet is lethal; toxic doses in dogs are low too. The most classic household poisoning: owners giving human medicine to a sick pet.

Can I make my pet vomit at home?

Home-induced vomiting is not advised: corrosive cleaners, sharp bones or existing neurological signs make it dangerous, and improper technique risks aspiration pneumonia. Vomiting should be induced by a vet with proper drugs at the right moment — most effective within 1-2 hours. So “head to the clinic as soon as you know” beats “try to induce vomiting first”.
