Stop the Roller-Coaster Effect of Equine Pain and Pain Relief

When it comes to non-steroidal anti-inflammatory drugs (NSAIDs) typically used to treat conditions such as the pain and inflammation associated with equine osteoarthritis, horse owners look for safety, consistency and convenience.

When it comes to non-steroidal anti-inflammatory drugs (NSAIDs) typically used to treat conditions such as the pain and inflammation associated with equine osteoarthritis, horse owners look for treatment that performs on three levels:

  • Safety
  • Consistency
  • Convenience

Tried and True

EQUIOXX (firocoxib) Brand Products have been tested on more horses in safety studies than any other NSAID, and remain the only NSAIDs approved by both the AQHA and the USEF for use up to 14 days.

Consistent Therapy 

Since some NSAIDs have a short half-life, meaning they leave the system fairly quickly, they require multiple doses each day. Multiple daily dosing can result in spikes and dips – possibly leaving the horse vulnerable to a roller-coaster effect of pain and pain relief. The active ingredient in EQUIOXX, firocoxib, has a longer half-life than other equine NSAIDs, so its levels stay steady for more hours, helping to eliminate this roller-coaster effect.

EQUIOXX tablets and paste may be given with or without feed or hay. With other NSAIDs, like phenylbutazone, feed — especially hay — delays time to peak effect.

With EQUIOXX, you can feel confident about achieving a consistent level of therapy for pain and inflammation relief throughout the entire day,” says Hoyt Cheramie, DVM, MS, Manager, Merial Large Animal Veterinary Services. “This means trainers and horse owners can spend less time worrying about whether or not the treatment is providing consistent relief and more time focusing on the horse.”

Three Choices, Same Proven Active Ingredient

EQUIOXX is the only coxib NSAID approved for horses, and it helps control joint pain and inflammation associated with osteoarthritis with just one daily dose. EQUIOXX is available in three formulations: injection, paste, and tablet, allowing treatment to fit your horse’s specific needs.

  • Injection (IV) is ideal to initiate therapy and is an excellent option for field and hospital settings.
  • Paste is a convenient form for accurate dosing, especially for small horses and performances horses that are subject to testing.
  • Tablets can be given with or without feed and are ideal for noncompetitive uses.

Talk to your veterinarian for more information and to discuss the best option for your horse.

*Joint pain and inflammation associated with equine osteoarthritis, also called degenerative joint disease.
†EQUIOXX Injection may be used for five of the 14 days.

As with any prescription medication, prior to use, a veterinarian should perform a physical examination and review the horse’s medical history. A veterinarian should advise horse owners to observe for signs of potential drug toxicity. As a class, nonsteroidal antiinflammatory drugs may be associated with gastrointestinal, hepatic and renal toxicity. Use with other NSAIDs, corticosteroids or nephrotoxic medication should be avoided. EQUIOXX has not been tested in horses less than 1 year of age or in breeding horses, or pregnant or lactating mares. For additional information, please refer to the prescribing information or visit
