My dog ate Nexium. Does my mini Dachshund need immediate vet care?
Hello. There is very little information on this product in veterinary medicine but based on information on similarly classed drugs, there should be little if any problems & is generally considered to be well tolerated. According to Plumb's Veterinary Formulary, Esomeprazole could potentially cause GI distress ( anorexia, colic, nausea, vomiting, diarrhea & C. diff. infections ) as well as rare hematologic & neurologic disturbances & urinary tract infections . Information on acute toxicity is also limited in veterinary medicine, but the LD50, or amount of this drug needed to kill 50% of rats administered this medication is greater than 4000mg per kg. Nugget consumed the equivalent of 7 mg per kg. So, I would just keep a good watch on Nugget. If she shows any GI signs, they should resolve on their own. If nothing is seen in the next 24 hours, you can stop worrying, but this one pill does not warrant any medical attention at this time. Thanks for using Petco Pet Education Center, formerly Petcoach.
