Updated July 2025

💡 Banamine, the trade name for flunixin meglumine, remains one of the most commonly used NSAIDs in equine medicine. As of 2025, its role in treating pain, inflammation, and mild colic is well‑defined—but so are the risks. This guide provides comprehensive, veterinarian‑approved advice on safe and effective use.

🔬 What Is Banamine?

• Generic: Flunixin meglumine
• Drug Class: Non‑steroidal anti‑inflammatory (NSAID)

📌 Approved Uses in 2025

• Relief of visceral pain and inflammation—especially mild colic
• Anti‑inflammatory action for musculoskeletal pain

⚠️ Important Injection Warnings

Never inject Banamine into the muscle—this can cause severe muscle necrosis and potentially fatal infections. Even intravenous (IV) injections, if not performed expertly, can lead to abscesses. If you’re not a veterinary professional trained in IV administration, it’s safer to switch to oral paste or tablets.

🩺 How Banamine Helps in Colic

• Reduces pain and inflammation, giving the horse’s gastrointestinal system time to resolve gas or mild impaction
• Note: Banamine does NOT improve gut motility or cure serious colic—it only treats symptoms. If surgical colic is suspected, immediate veterinary intervention is required.

🔁 Dosing Frequency & Toxicity Risks

• Banamine has a ~12-hour duration of action. Dosing more often increases the risk of NSAID toxicity.
• Signs of NSAID toxicity include gastrointestinal ulcers, kidney damage, and liver dysfunction.
• Always follow your veterinarian’s dosing plan. Do NOT administer more frequently than every 12 hours without professional approval.

⚠️ NSAID Combination Caution

Never combine Banamine with other NSAIDs (like phenylbutazone, Previcox®, or dipyrone). Doing so significantly raises the risk of kidney, liver, and gastrointestinal harm.

📋 Safe Use Checklist

• Administer via oral route unless IV expertise is confirmed.
• Follow the 12-hour dosing interval—no more, no less.
• Do NOT stack with other NSAIDs.
• Report any signs of colic, ulcers, or kidney issues to your vet promptly.
• Always have a veterinary exam for colic—do NOT use Banamine as a “first-aid” substitute when serious issues are possible.
