Clopidogrel, commonly known by the brand name Plavix, is a prescription antiplatelet medication used in humans to reduce the risk of blood clots. In veterinary medicine, it is occasionally prescribed off-label for dogs and cats with certain heart or blood clotting conditions, but it must only be given under direct veterinary supervision. Because it interferes with normal blood clotting, even a small amount above the prescribed dose—or accidental ingestion of human medication—can cause dangerous bleeding.
Pets most often become exposed by chewing on a dropped pill, getting into a pill bottle, or being given a human dose by mistake. Cats may be especially sensitive to medication errors because of their small size. Unlike some toxins that cause immediate vomiting, clopidogrel’s effects may not appear for hours or even days, which can make early detection difficult.
To protect your pets, store all prescription medications in a secure cabinet out of reach, and never give your pet human medication without first consulting your veterinarian. If you suspect your dog or cat has eaten clopidogrel, contact your veterinarian or a pet poison control center right away, even if symptoms are not yet present.
