Previcox (firocoxib) is a prescription-strength nonsteroidal anti-inflammatory drug (NSAID) formulated specifically for dogs. It is used to relieve pain and inflammation associated with canine osteoarthritis and to manage post-operative pain from soft-tissue and orthopedic surgeries. Previcox is fast-acting, highly targeted, and easy to administer thanks to its palatable chewable tablet form.
Each tablet contains firocoxib, a COX-2 selective NSAID that blocks enzymes responsible for inflammation, pain, and fever in the body—without affecting enzymes that protect the stomach lining. With once-daily dosing, Previcox offers long-lasting relief to improve your dog’s mobility and overall quality of life.
Firocoxib inhibits the cyclooxygenase-2 (COX-2) enzyme, which is responsible for producing prostaglandins that cause inflammation, pain, and fever. By blocking COX-2 while sparing COX-1, Previcox reduces inflammation while minimizing gastrointestinal side effects common with traditional NSAIDs.
