Carprofen is prescribed to relieve pain and inflammation caused by arthritis and other joint problems, so you can help your dog maintain her regular activity levels and quality of life. Carprofen may also help to reduce pain associated with surgeries and other painful conditions and works by limiting your dog's production of prostaglandins, which are substances that can trigger inflammation. **We directly source prescription medications from manufacturers and wholesale distributors registered with the FDA and licensed by applicable state boards.
