The active ingredient in Previcox is Firocoxib, a class NSAID that inhibits the release of cyclooxygenase-2 (COX-2) and stimulates the production of cyclooxygenase-1 (COX-1). This, in turn, minimizes the production of prostaglandins, thereby reducing joint pain and inflammation.

How Long for Previcox to Work in Dogs?

Being one of the most effective class cyclooxygenase inhibitory NSAIDs, Previcox starts relieving pain and inflammation in your dog within hours of being administered. However, it'll take a few days (up to a week) before you notice any significant changes in your dog's mood and behavior.

The time taken for Previcox to work also depends on other factors, such as your dog's age, weight, and overall health. Make sure you follow the vet's instructions regarding the dosage and frequency of administering Previcox to your dog.

What Are the Side Effects of Previcox for Dogs?

  • Seizures
  • Loss of appetite
  • Itchiness
  • Diarrhea (often accompanied by dark, tarry, or bloody stool)
  • Abdominal pain
