Toxicity to pets

Aspirin is a common over-the-counter (OTC) non-steroidal anti-inflammatory (NSAID) used in both human and veterinary medicine. When used at appropriate doses in pets, aspirin can help with inflammation, pain management for osteoarthritis, and clot prevention in cardiac patients. However, when aspirin (or its similar salicylate-containing compounds) is inappropriately ingested, it can result in severe poisoning in dogs and cats. Sources of aspirin include Pepto-Bismol®, topical medications (e.g., shampoos, medications for acne, warts, calluses, etc.), make-up (e.g., foundations and concealers), sunscreen, liniments (e.g., Bengay®, HEET®, Icy Hot, etc.), and oil of wintergreen.

Cats are much more sensitive to aspirin poisoning than dogs. Signs of aspirin poisoning in dogs or cats include: 1) gastrointestinal signs, 2) respiratory changes, 3) elevated body temperature, 4) bone marrow suppression, 5) kidney failure, and 6) central nervous system signs. Aggressive treatment is necessary with exposure to toxic amounts, and can involve decontamination, supportive therapy such as fluid support and medications to treat the pet’s clinical signs, along with blood work monitoring.

If you suspect your dog or cat were poisoned by aspirin, call your veterinarian or Pet Poison Helpline® immediately for life-saving treatment recommendations.
