Is Ibuprofen Toxic to Dogs?

Ibuprofen, a nonsteroidal anti-inflammatory (NSAID), is a popular pain reliever and fever reducer. While it is a relatively safe medication for humans, ibuprofen is not appropriate for dogs.

  1. A Common Mistake

    • According to the American Society for the Prevention of Cruelty to Animals, ibuprofen is the No. 1 cause of accidental poisoning in cats and dogs.

    Dangerous Effects

    • When given to a dog, ibuprofen can cause stomach ulcers, internal bleeding, kidney failure and even death.

    Signs of Ibuprofen Toxicity

    • A dog who has ingested a dangerous amount of ibuprofen will show classic symptoms of poisoning, including vomiting, diarrhea, stumbling, lethargy and abdominal pain.

    Toxicity Threshold

    • Even very low doses of ibuprofen can cause stomach ulcers in dogs. A dog should never ingest more than 50 mg of ibuprofen per pound of body weight.

    What to Do

    • If you know or suspect that your dog has ingested ibuprofen, contact a veterinarian or the ASPCA poison-control hotline (888 426-4435) immediately. Prompt treatment can save your pet's life.
