Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 4 years and 1 month old | 110 lbs
My 100pound Labrador retriever was taking 100 mg of deracoxib prescribed by a veterinarian. I ran out and started giving her carpofen that was previously prescribed for another dog; 100 mg carpofen twice daily. I didn’t realize the must be a washout period. I only started the carpofen yesterday. Should I immediately stop and start a washout period?

Good evening! As both carprofen and deramaxx are nonsteroidal anti-inflammatories, you are correct that they should not be used consecutively. I would withhold all medications until reaching out to your regular veterinarian or a poison control center (aspca or pet poison control) to discuss if any further treatment needs to be considered. Good luck!
