Almost every horse owner has or will use non-steroidal anti-inflammatory drugs or NSAIDs at some point. Whether used for chronic conditions like osteoarthritis or for acute injuries, NSAIDs help keep your horse comfortable while reducing the effects of uncontrolled inflammation.
The most commonly used NSAIDs for horses are phenylbutazone, flunixin meglumine, Banamine, diclofenac sodium,m Surpass cream, and firocoxib Equioxx. These medications are often prescribed by veterinarians to manage pain and inflammation associated with injuries, arthritis, and other health conditions.
How Do NSAIDs Work in Horses
NSAIDs block the production of an enzyme called cyclooxygenase or COX that the body uses to produce prostaglandins. Prostaglandins are hormone-like chemicals that are released at the site of an injury to control pain, inflammation, and blood clotting.
Pain and inflammation are normal bodily reactions to illness and injury. Swelling occurs when blood rushes to the injury site to deliver infection-fighting white blood cells and begin the healing process. Pain also signals to your horse that they must slow down and avoid further injury.
By inhibiting COX production, NSAIDs reduce pain that may be affecting your horse’s quality of life. In some cases, NSAIDs are also necessary to prevent tissue damage caused by excessive inflammation.
There are different types of COX enzymes produced within the body. COX-1 is responsible for protecting the digestive tract. COX-2 is produced at the site of injury or inflammation. Selective NSAIDs, also known as COX 2 inhibitors, are often gentler on the digestive system because they primarily target COX 2 enzymes.

Common Side Effects of NSAIDs for Horses
While NSAIDs are highly effective at controlling pain, they can interfere with the body’s natural healing process. It is best to keep dosages as low as possible while still maintaining effectiveness and to avoid prolonged use whenever possible.
One of the biggest concerns with NSAID use is their harmful effects on the gastrointestinal tract. Prostaglandins help maintain blood flow and mucus production in the digestive tract, protecting tissues from damage caused by stomach acid.
When these protective mechanisms are reduced, horses may develop several complications, including
- Ulcers in the mouth or on the tongue
- Stomach ulcers
- Right dorsal colitis
- Kidney damage or failure
Supportive digestive products and treatments may help horses at risk of gastrointestinal issues. Browse the Horse Digestive Health category to learn more.
Monitor Your Horse for Signs of NSAID Side Effects
NSAIDs can sometimes cause ulcers on the tongue and other soft tissues in the mouth. Oral ulcerations may lead to drooling, reluctance to eat, or visible sores and blisters.
Gastrointestinal symptoms may include reduced appetite, diarrhea, unexplained weight loss, and recurring colic. Horse owners should also watch for increased drinking and urination, which may signal potential kidney stress or damage.
If you notice any of these symptoms, contact your veterinarian immediately for evaluation and guidance.
Preventing Side Effects When Using NSAIDs
Your veterinarian will prescribe NSAIDs that are appropriate for your horse’s condition and medical history. Administering pain medication without veterinary guidance increases the risk of adverse effects.
For horses at increased risk of gastrointestinal complications, such as those with a history of colic or those requiring long-term treatment for conditions like osteoarthritis, veterinarians may recommend a COX-2 inhibitor. Even selective medications still carry some risk and should be used carefully.
Horses that are ill or dehydrated are also at greater risk for kidney damage. If your horse has not been eating or drinking normally, do not administer NSAIDs without veterinary advice.
To help reduce risks when using NSAIDs
- Never exceed the prescribed dose
- Avoid combining multiple NSAIDs at the same time
- Follow your veterinarian’s instructions closely
- Monitor your horse for any unusual symptoms
If your horse requires long-term pain support, it may also be helpful to explore joint care solutions available in the Horse Joint Supplements category.
Alternatives to NSAIDs for Horse Pain Management
When used properly, NSAIDs are generally a safe and effective way to manage pain in horses. However, they should be used thoughtfully and only when necessary.
Natural approaches to pain management may sometimes be used alongside medications or in milder cases instead of them. For example, veterinarian-recommended T Relief tablets are a plant-based pain reliever that has been used for decades in both humans and animals.
Always consult your veterinarian before trying any new supplement or remedy, as even natural preparations may have contraindications.
Cold therapy is another simple and effective option for reducing inflammation. Applying an ice pack or hosing the affected area with cold water for about twenty minutes at a time up to four times per day can help control swelling and discomfort. Be careful not to overuse cold therapy since prolonged exposure may damage already injured tissue.
Finally, allowing your horse adequate rest is one of the most important aspects of recovery. Giving the body time to heal rather than masking pain can help ensure the best chance of a full and lasting recovery.
