• Washout Periods: If you are switching a dog to Firocoxib from another NSAID (like Carprofen or Meloxicam) or a steroid (like Prednisone), veterinarians always recommend a 5 to 7 day washout period to clear the old medication from the system and prevent severe gastrointestinal side effects.

What Is Firocoxib for Dogs?

Firocoxib, more popularly known as Previcox dosage for dogs, is a prescription non-steroidal anti-inflammatory drug (NSAID) that is prescribed to help alleviate pain, inflammation, swelling and stiffness in the dog. It is FDA-approved for treating osteoarthritis pain and for controlling postoperative pain and inflammation after certain soft-tissue and orthopedic surgeries.

Firocoxib dosage for dogs is effective because it inhibits an enzyme, called cyclooxygenase-2 (COX-2), that helps make chemicals that cause inflammation (prostaglandins). These chemicals are responsible for the swelling, inflammation and pain messages in damaged and arthritic tissues. Firocoxib is a selective inhibitor of COX-2 and is relatively inactive at COX-1, which might lead to a reduction in some of the digestive side effects and might be kinder to the stomach and intestines than some traditional NSAIDs.

Most dogs do well on Firocoxib dose for dogs when used properly, both for short term and long term pain management. It can also be used off-label by veterinarians for inflammation or pain associated with other diseases such as some skin diseases, colorectal polyps and some cancers. It is prescription-only medicine and is usually marketed as chewable tablets in various strengths from vets and veterinary pharmacies. Not approved or recommended for use in cats.

• Antifungal drugs (e.g fluconazole): May have interaction effects
• Radiation therapy drugs: radiation therapy may increase the toxicity of chemotherapy drugs, such as methotrexate.
• Increased blood levels of protein-bound drugs (like phenytoin or valproic acid) which means that the effects of these drugs are increased.
