My 8-week puppy ate wrong medication, expired Deramaxx. What to do?

Hi there! Since Primo is 84 pounds (about 38 kilograms), 150 mg of Deramaxx would be a dose of about 4 mg/kg. This is within the approved label dosing range for this medication for short-term use, so it's unlikely that you will see any serious side effects related to this - especially since you were able to make him vomit within about an hour, so he probably vomited up at least part of the medication before it was fully absorbed. With any higher-than-normal dose of Deramaxx, it's always possible to see GI issues such as stomach upset or even gastric ulcers - so I would recommend monitoring Primo closely for the next few days to make sure that he's acting normal. If he has repeated episodes of vomiting (more than once or twice), doesn't want to eat, or begins acting lethargic, then I would recommend taking him to the vet right away to be checked out. If he normally takes Deramaxx daily, I would also recommend calling your regular vet in the morning to let them know that this happened - they may recommend skipping his normal dose for the next day or two to help minimize the risk of any problems.

Wormers are generally considered very safe medications and although some vomiting or diarrhea may develop this should resolve uneventfully. Some types can cause tremors and neurological signs and you should contact an emergency vet and inform them of the brand, timing and dosage if you notice any unusual symptoms

Hi there! I'm so sorry to hear about Remy's troubles! However, w To better answer your question, it would be ideal to know which deworming pill was administered, and how many milligrams! Knowing that information will help one of us let you know for sure if it's an issue or not! However... praziquantel is usually prescribed for tapeworms, and sold often in 34mg tablets. For a 6-10 pound dog, 34mg is the dose. Again, if this is not what you gave, let us know so we can look into it for you! Thanks!

A one time double dose of deramaxx should not cause major problems. Signs to watch for anytime they are on an anti inflammatory medication include decreased appetite, vomiting, or dark back stool. If any of these signs are noted stop the deramaxx and call your vet. Baron should do ok!!

Hi and thanks for posting. I wouldn’t worry too much about this. Griffen consumed more towards the maximum dosage of this medication (4mg per kg of body weight) but he should be ok as long as he is not on any similar medications. He may have some gastrointestinal discomfort such as vomiting and diarrhea as a side effect of the medication. If he is on any similar medications, I would be sure and let us know so we can advise further. I hope this helps!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! In the US we do not use Albendazole in dogs or cats. If Oscar only weighs 5.5 lbs and if he was given 5mls that is 200mg of albendazole and at that dose it has been reported to cause mental dullness and decreased appetite in cats. It can also affect white and red blood cells. I don't have much information about overdoses in dogs. Stop giving him the medication. The dose of ivermectin should be ok. If he gets worse or doesn't improve he should be taken to an emergency hospital. Good luck!

It could be the horse dewormer you gave Silvi. Horse dewormers are not appropriate to give to puppies, and depending on the one you gave her, can contain ingredients that are toxic to puppies. You need to get her into a vet immediately for an exam and treatment, as if she is suffering from a toxicity, there is a potential it could be fatal without treatment. Bring in the horse dewormer as well so the vet can see what you have given her. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Good luck!
