She is 13 yr. Old small, overweight dog. Went to vet 1/14/18 due to her not using her left hind leg. She was diagnosed with inflammation and prescribed Galliprant 20mg to be taken 1 every 24 hrs. She took one yesterday and will take another this evening. However, today she has not been her regular self. She has not eaten since morning and has vomited several times. She has began to pant and tremble...I don't know what to do. Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 13 years and 8 months old | 19.6 lbs

The first thing I would do is ask myself if the Galliprant has helped at all with the pain and lameness associated with the leg. The next thing I would ask myself if whether or not any of these other problems existed prior to your original vet visit, or if they occurred immediately after the Galliprant was administered. In general, Galliprant is an extremely safe medication that has almost no known side effects, EXCEPT for vomiting. Panting and trembling could be caused by the general discomfort from the vomiting episodes, or it can be a result of the pain she's experiencing. Ultimately, if the Galliprant is the cause of the vomiting, obviously discontinuing this medication may be in her best interest even if it is helping with the pain. Other medicatiosn are available to addres pain and inflammation that may result in few side effects. You will need to speak with your primary vet about these findings and possibly schedule another visit if need be. Hope this helps.
