Is Celecoxib (Celebrex) Safe for Dogs?
Why it’s a problem
Although celecoxib has been formulated for veterinary use, the human capsules are not safe to give at home, and dogs that swallow them risk stomach ulcers, GI bleeding, and kidney injury. Small dogs are at higher risk from a single capsule. Signs can be delayed, which makes exposure easy to underestimate.
How to keep your pet safe
Keep celecoxib bottles stored away from dogs, and never share your arthritis medication with a pet. If your dog has joint pain, ask your vet about a dog-approved NSAID such as carprofen at a proper dose.
Warning signs to watch for
Vomiting (sometimes with blood), diarrhea, drooling, belly pain, lethargy, loss of appetite; larger ingestions can cause wobbliness, seizures, and little or no urine from kidney failure.
When to call the vet
Call a vet or a pet poison hotline as soon as you learn of the ingestion. Do not induce vomiting unless a professional tells you to.
Common questions
My dog ate one of my Celebrex capsules — is that dangerous?
Yes, it needs prompt attention. Celecoxib can cause stomach ulcers and kidney injury in dogs, and small dogs are at particular risk. Call your vet or a pet poison hotline now.
Is celecoxib ever used in dogs?
Veterinarians have used celecoxib formulations in dogs, but only under prescription with carefully chosen doses. Human capsules dispensed at home are not a safe substitute.
How soon would symptoms appear if my dog ate celecoxib?
Stomach upset can start within hours, but ulcer bleeding and kidney injury may not show for a day or more. Early veterinary care is easier and safer than treating damage later.
