Is Paracetamol Safe for Pets?

Paracetamol is one of the most common medications in Australian households. It is also one of the most dangerous things a dog or cat can consume.

This question comes up regularly at Middle Brighton Vet - usually from a well-meaning owner whose pet is in pain and who wants to help. Here is the direct answer.

Is paracetamol safe for dogs?

No. Paracetamol is not safe for dogs. While some veterinary references cite very low doses being used in specific circumstances under strict veterinary supervision, there is no safe dose of paracetamol that a dog owner should administer at home. The margin between a dose that might have some effect and a dose that causes serious toxicity is too narrow to manage without clinical monitoring.

In dogs, paracetamol toxicity causes liver damage. Signs include vomiting, lethargy, abdominal pain, and jaundice. Severe cases progress to liver failure.

Is paracetamol safe for cats?

Absolutely not. Cats are acutely sensitive to paracetamol and a single standard human tablet can be fatal. Cats lack a specific liver enzyme needed to metabolise paracetamol safely, causing it to accumulate as a toxic compound that damages red blood cells and causes liver failure. Signs include difficulty breathing, swollen face and paws, brown or discoloured gums, and profound lethargy. This is a genuine emergency.

What about ibuprofen and other human pain medications?

Ibuprofen, aspirin, and other NSAIDs designed for humans are also toxic to dogs and cats. They cause gastrointestinal ulceration and kidney damage. There is no safe human NSAID for home use in pets.

What should I give my pet for pain instead?

Nothing from your medicine cabinet. If your pet is in pain, call us. We have veterinary pain relief options that are safe and effective for dogs and cats, and we can assess whether there is an underlying cause that needs treatment.

Pain in pets is often a sign of something that needs diagnosis, not just management. A limping dog that is given pain relief at home may walk better but the underlying injury or disease continues to progress.

When to call us

If your pet has consumed any paracetamol - even a small amount - call us immediately or contact the Animal Poisons Helpline on 1300 869 738. Do not wait for symptoms. Early treatment is significantly more effective than treatment after clinical signs appear.
