Hi. I am Dr. Elizabeth Ann. Thanks for using JustAnswer.
You can definately give previcox and tramadol together. Previcox is an anti-inflammatory drug. It helps to reduce pain by reducing inflammation. It is similar (but not the same) to aspirin or ibuprofen etc.
Tramadol is a pure pain medication. Think of it as a doggy vicoden. When the pain is too much for just the anti-inflammatory med to handle it, then it can be used. It may cause drowsiness.
I'm sorry, the chat session got interrupted. You CAN give her another dose of tramadol tonight. It can be given at the same time as the previcox if needed (but I am just speaking of the future, she does not get another previcox dose tonight). The two do not interact together. Gabapentin is another purely pain medication. It isn't really understood as far as its pain relief properties. It can potentially be used along with the other two meds and it is used once daily. I have not used it.
If your pup is not improving with pain, she should be re-evaluated.
I hope this helps you and I hope your dog is feeling better soon.
I am sorry to hear that. Did they check a chest xray to look for any spread of cancer to the lungs? The tramadol may cause some of the breathing changes now, but I would be concerned about the breahting changes that were occuring before this.
I hope that you can get some pain relief to her tonight. Bone cancer is notoriously painful. I wish you the best.
