TL;DR: Ibuprofen is highly toxic to dogs and requires immediate veterinary intervention to prevent life-threatening kidney failure and internal bleeding. Even if your dog is not showing symptoms, you must contact a professional immediately as even small doses can be fatal.
What happens when a dog ingests ibuprofen?
Ibuprofen is a common human non-steroidal anti-inflammatory drug (NSAID) found in brands like Advil and Motrin. While these medications help humans with pain and inflammation, they are highly toxic to dogs. A dog's body cannot break down ibuprofen efficiently, leading to a rapid and dangerous buildup in their bloodstream.
Is it a medical emergency if my dog eats ibuprofen?
- Urgency Level: High. This is a critical medical emergency.
- Ibuprofen toxicity can cause severe gastric ulceration, life-threatening internal bleeding, and acute kidney failure.
- Because dogs are much more sensitive to this drug than humans, even a small dose can be fatal.
- You must contact a veterinarian or a pet poison control center immediately, even if your dog is not yet showing symptoms.
How does a photo of the medication help the veterinarian with triage?
- Take a quick photo of the medication packaging or bring the bottle with you to the clinic.
- This allows the veterinary team to identify the exact milligram (mg) strength of the tablets.
- Vets can check for other harmful ingredients, such as Xylitol, which may be present in the medication.
- Having the exact dosage information helps the vet calculate the toxicity level based on your dog's weight and speeds up the delivery of life-saving treatment.
Clinical Context (Merck Veterinary Manual)
Ibuprofen has a narrow margin of safety in dogs; prolonged use at 5 mg/kg may cause gastric ulcers and perforations. Single acute ingestions of 100-125 mg/kg can cause vomiting, diarrhea, nausea, abdominal pain, and anorexia. Renal failure may follow dosages of 175-300 mg/kg, while CNS effects, including seizures, ataxia, depression, and coma, in addition to renal and GI signs can be seen at dosages exceeding 400 mg/kg. Dosages above 600 mg/kg are potentially lethal. Treatment of NSAID toxicosis consists of early decontamination by inducing emesis if recent exposure, followed by administration of activated charcoal with a cathartic, and repeated every 6-8 hours. GI and kidney protection, along with supportive care, are also indicated. H1-receptor antagonists may be useful in treating GI ulcers.
