My cat ate ibuprofen. Is it toxic? What emergency steps should I take?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 6 years and 2 months old | 8 lbs

I gave my kitty ibuprofen...she is FIV positive and the meds the vet gave arent working and i couldnt take it anymore. She had one last night and one at noon today and seems ok...even better. Is she going to die? Approx 700mg of ibuprofen in 48 hours. No obvious symptoms. Pain has decreased.

Hi there and thank you for your question. Giving ibuprofen to a cat can be very very toxic. Cats are extremely sensitive to NSAIDS in general (even veterinary Rx ones), so the Ibuprofen given is certainly a serious concern here. 700mg is a lot for one 8 lbs cat to ingest. Signs of ibuprofen toxicity would include vomiting, blood vomit, diarrhea, weakness, pale gums, lethargy, loss of appetite , seizures, and back tarry stool. Ibuprofen can cause GI ulcers, liver damage, and kidney failure. I would absolutely seek emergency veterinary care and treatment for her today, keeping in mind signs of toxicity may be delayed. They will need to give her IV fluids, check her kidney and liver function, give GI protectants, and monitor her vital signs. In the future, any OTC human pain medication is toxic to give to cats and is not okay to give to Willow. I hope Willow gets well soon. Thank you for using Petco Pet Education Center, formerly Petcoach!
