My dog ate Previcox and is acting strange and skittish. Is he okay?

Oh dear! This is a pretty significant overdose, and NSAIDs (non-steroidal anti-inflammatory drugs) like Previcox have a fairly narrow margin of safety in dogs. Overdoses like this can result in severe stomach ulcers, internal bleeding, or even kidney failure. Since she got such a large dose, I would really recommend taking her to the vet right away for treatment. He/she can give her an injection to induce vomiting to help get any remaining pills out of her stomach before they can be absorbed, and may also recommend giving her IV fluids and starting medication to help protect her stomach to try and prevent any problems.

I am sorry to hear about your concern for Hallie. It is unlikely with a one time extra dose of her previcox that we will see any major concerns. The most common side effect would be GI upset such as vomiting, decreased appetite, or diarrhea. I would just monitor her for these signs and contact your vet if they occur (you can try feeding a bland diet of plain cooked rice and boiled shredded chicken breast for a day if they occur, if they continue a vet visit is needed). Most likely she will have no symptoms after this one time extra dose.

Hello, I am sorry to hear about Nala. Previcox is a nonsteroidal anti-inflammatory (NSAID) medication used for injuries like the one you described. Possible side effects of NSAIDs include gastrointestinal side effects, such as ulcers in the stomach and harm to the kidneys. Dogs are more likely to experience these side effects if the medication is given on an empty stomach or for long periods of time.. Some dogs are also just more sensitive to these side effects in general. The dark color of Nala's vomit is concerning, and I would be worried that she may be experiencing some of the side effects of Previcox. I would recommend having her evaluated by a veterinarian so that they can examine her and prescribe medications to help with potential gastric ulcers. Hope this helps, good luck!

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. Great question! No, I would not be worried about this scenario. Typically we don't like to give two different NSAIDs very close together but that is mostly when a dog has been on one long-term and we want to switch to another. Has only having one dose of previcox a few days is not really concerning. The main reason we worry is the potential for gastric ulceration. If you want to be cautious you could give him some omeprazole for a week but it would be best to contact your vet before adding in any other medications. Hope this helps. Best wishes!

That would be an unusual side effect of Previcox, especially if he just had one dose. If that continues then you should call your vet and let him/her know as your vet may want to check a urine sample.

I would still have Rover checked out by a vet to be safe. Overdoses of Loxicom can cause acute kidney failure, and that will take a couple of days for it to show symptoms. It's best to have his kidney function checked now with bloodworm and again in a few days to make sure they are working well. I'd bring him into a vet now. Best of luck, I hope this helps!

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.
