Dog on carprofen for pain: Why is he suddenly peeing inside?

Carprofen is an nonsteroidal antiinflammatory medication (NSAID) like aspirin or ibuprofen for humans. It's used daily for arthritis or other chronic pain, and short term for more acute/temporary pain. The half life is the amount of time it takes for half of the drug to leave the body (via the liver, kidneys/bladder, or gut). Carprofen can occasionally have side effects on the liver, so if he's going to be on it long term, it's usually recommended to check liver values after 2 weeks. That said, liver issues are rare. Intestinal upset (vomiting/diarrhea) are also possible side effects and if he had any of that you'd want to stop and figure out a different appropriate medication with his vet. With just 6 days of medication, no additional testing will be done. You can (and should, if that is how it was prescribed) give carporfen daily. Appropriate supplements could include fish oils and glucosamine and others, depending on what exactly is going on. I'd recommend asking about supplements for long term when you go for your recheck visit

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.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is concerning as the Rimadyl is supposed to be helping but things continue to be about the same. This could be due to a neurological issue for example. I would encourage you to check in again with your veterinarian to have Lex reevaluated as she has not improved much. They could consider another medication such as gabapentin or more advanced diagnostics to try to diagnose the matter. Best of luck!

Without reviewing the full blood results and changes over time it is very difficult to say for sure but if your dog is unwell (especially with increased thirst, vomiting or diarrhea) and blood results are developing more concerning changes then I would be concerned about continuing with carprofen until a conclusion can be reached as to what is causing the chenges in the blood work. Obviously however, Buddy is in pain and shoudl be receiving some pain relief in order to improve his comfort leveles - you shoud speak to your vet about other types of pain relief or deek referral to a specialist

I wouldn’t recommend it -carprofen may not be safe for dogs that have underlying medical conditions like a sensitive stomach, kidney or liver disease. Older dogs are more likely to have an issue like this. If Goose was prescribed carprofen in the recent past it might be a little safer but otherwise I’d recommend talking to your vet first. Sadly there is not another over the counter pain option that I’d consider to be safer so if you feel he’s in significant pain you may want to consider seeing a vet tonight.

Tramadol is an opioid meant to alleviate moderate pain, however there are research papers now that determined it is not that effective. Carprofen is a non-steroidal anti-inflammatory medication (like aspirin, but for dogs) which is given for certain types of pain such as arthritis. However Carprofen is excreted via the kidneys and if it is to be used, the dog receiving it needs to have a small blood test to verify that his kidneys are working properly. Also carprofen can cause stomach ulcers in some dogs. So unless your vet prescribes these medications for your dog, please do not give them. However, should your vet prescribe those medications for your other dog, you can tell him that you have them and then be informed of the proper dosage to give.

Yes, this is a common side effect of this medication. Temaril-P contains prednisolone, which is a steroid - this is very effective at relieving allergy-related itching as well as a variety of other conditions, but it often causes increased thirst and urination as a side effect. In some dogs, this can be severe enough to cause urinary accidents in the house. This isn't dangerous at all, but can definitely be annoying for dog owners! I would recommend calling your veterinarian in the morning to let them know that Marley is having this problem. He/she may recommend reducing her dose to decrease the chance of further accidents.
