Equioxx for Horses Cost & Firocoxib NSAID: 2026 Price Guide
Essential Pricing Takeaways
- • Equioxx (firocoxib) is a highly selective COX-2 inhibitor, offering superior gastric, intestinal, and renal safety profiles compared to phenylbutazone ("bute").
- • Available in scored 57mg oral chewable tablets, oral paste syringes, and injectable formulations for precise daily weight-based dosing.
- • Purchasing 180-tablet bottles through licensed online veterinary pharmacies slashes daily chronic pain management costs down to approximately $1.00 per day.
- • Strict adherence to USEF and FEI withdrawal periods (12 hours pre-competition) and single-NSAID stacking rules is legally required for competitive equines.
Chronic osteoarthritis, navicular disease, and recurrent soft tissue inflammation are leading causes of performance decline and chronic lameness in adult and senior horses.
Equioxx (firocoxib) is a breakthrough, second-generation coxib-class non-steroidal anti-inflammatory drug (NSAID) engineered specifically to control joint pain without inducing the severe gastric and renal toxicities associated with traditional equine medications.
While mobile veterinary practices frequently bill Equioxx chewable tablets at $2.20 to $2.80 per day ($390+ for a 180-count bottle), horse owners who purchase authentic 180-count economy bottles through accredited online pet dispensaries pay only $0.98 to $1.15 per day, saving up to $200 per bottle on ongoing lameness maintenance.

COX-2 Selectivity: Why Equioxx Is Safer Than Phenylbutazone ("Bute")
Traditional non-steroidal anti-inflammatory drugs like phenylbutazone ("bute") and flunixin meglumine (Banamine) non-selectively inhibit both cyclooxygenase enzymes: COX-1 and COX-2. While inhibiting COX-2 stops the production of inflammatory prostaglandins that cause joint pain and lameness, inhibiting COX-1 strips the horse of cytoprotective prostaglandins that maintain stomach mucosal blood flow and renal perfusion.
Equioxx is a coxib-class NSAID engineered to selectively inhibit COX-2 while sparing COX-1 (operating on the same selective anti-inflammatory philosophy as canine Galliprant EP4 antagonists and superior to older non-selective NSAIDs like generic Carprofen). In veterinary clinical trials, horses treated with firocoxib for up to 42 consecutive days exhibited a dramatic reduction in gastric ulceration and zero incidence of right dorsal colitis—a frequently fatal necrotizing enteropathy triggered by chronic phenylbutazone administration.
Chewable Tablets vs. Oral Paste: Dosing and Cost Dynamics
Equioxx is manufactured in two primary oral formulations: 57mg scored chewable tablets and an oral dial-a-dose paste syringe. The chewable tablets are dosed at 0.1 mg/kg (one 57mg tablet treats an 800 to 1,300 lb horse once every 24 hours) and represent the most cost-effective format for long-term daily management.
The oral paste syringe delivers three daily doses for an average 1,200 lb horse and is ideal for short-term acute flare-ups or for horses with severe dental disease that cannot chew solid tablets. However, when calculated on a per-day basis, chewable tablets purchased in 180-count bottles cost approximately $1.05 per day, compared to $7.65 per day for oral paste syringes.
Equine Competition Rules: USEF and FEI NSAID Guidelines
Equestrians competing under United States Equestrian Federation (USEF) or Federation Equestre Internationale (FEI) governance must adhere to strict therapeutic substance rules. Firocoxib is permitted under USEF regulations provided it is the SOLE non-steroidal anti-inflammatory drug administered to the horse.
"NSAID Stacking"—administering Equioxx concurrently with phenylbutazone, Banamine, or Surpass—is strictly prohibited and results in immediate disqualification, fines, and competition bans. Furthermore, Equioxx must be administered at least 12 hours prior to competition, and owners must file an official USEF Medication Report Form documenting the treatment indication.
