Cats should never be given ibuprofen; even one human tablet can be life‑threatening and is considered an emergency that needs a vet immediately.

Is ibuprofen safe for cats?

  • Ibuprofen is highly toxic to cats, even at very low doses.
  • It can cause stomach and intestinal ulcers, kidney failure, liver damage, seizures, and death.

If you remember nothing else from this article: do not ever give a cat ibuprofen for pain.

What happens if a cat gets ibuprofen?

Because cats cannot metabolize ibuprofen well, the drug stays in their system at high levels for a long time, so even a single 100–200 mg tablet can be dangerous for an average cat. Damage often starts in the stomach and intestines, then the kidneys, and in more serious cases the brain and nervous system.

Common signs (which may appear within a few hours) include:

  • Vomiting (sometimes with blood) or diarrhea
  • Not eating, drooling, or signs of belly pain
  • Black, tarry stools (digested blood)
  • Extreme tiredness, weakness, or collapse
  • Drinking or peeing more or less than usual
  • Unsteady walking, tremors, or seizures in severe cases

What to do if your cat had ibuprofen

If you think your cat might have eaten ibuprofen or was given a dose, treat it like a true emergency.

  1. Call a vet or emergency clinic immediately and tell them the drug name, strength (e.g., 200 mg tablet), and how many tablets may be missing.
  1. Do not make your cat vomit unless a vet specifically tells you to do so; in some cases it can make things worse.
  1. Follow the vet’s instructions; treatment may include inducing vomiting at the clinic, activated charcoal, stomach protectants, and IV fluids to support the kidneys.

The sooner treatment starts, the better the chances of survival and of avoiding permanent kidney damage.

What can I give my cat for pain instead?

  • Do not give any human painkiller (ibuprofen, naproxen, aspirin, paracetamol/acetaminophen) to a cat without explicit veterinary direction; several of these are extremely toxic to cats.
  • Vets have cat‑specific pain medicines (such as certain veterinary NSAIDs or opioids) and will choose a drug and dose that are safe for your cat’s condition and organs.

If your cat seems painful (limping, hiding, not jumping, crying, or not grooming), the safest and only recommended step is to book an urgent vet exam rather than using anything from a human medicine cabinet.
