FDA-Approved Ulcer Prevention — Before the Haul, Not After the Signs
UlcerGard® (omeprazole) is the only non-prescription formula proven to prevent Equine Gastric Ulcer Syndrome in healthy horses. Each syringe holds four marked daily doses for horses weighing 600 to 1,200 lbs.
The Problem
Your Horse Can't Tell You When Something Hurts
It’s before dawn on haul-out day, and you’re making one last pass down the barn aisle. Your horse has picked through breakfast instead of cleaning up, and you’re wondering whether it is nerves, an ordinary change in appetite, or something that deserves a closer look. The trailer is hooked up, the stalls are booked, and your schedule says go—but your horse cannot explain what feels different.
Every attentive rider knows how unsettling that uncertainty can be. Decreased appetite, recurrent colic, intermittent loose stools, a dull coat, poor body condition, and slipping performance can be associated with gastric ulcers, but those signs can also point to other conditions. Even when your horse looks generally healthy, travel, stall confinement, training, racing, showing, and competition can introduce changes in routine that deserve thoughtful gastric-health planning.
The cost is not limited to an entry fee or a missed ride. You may spend the weekend watching every manure pile, checking the water bucket, and questioning each change in expression instead of focusing on your horse’s comfort and the work you prepared to do together. If the signs continue, guessing can also delay the veterinary evaluation needed to identify whether ulcers—or another health problem—are responsible.
That is what makes prevention a separate decision from treatment. UlcerGard® is intended only to prevent gastric ulcers in healthy horses; it is not a substitute for diagnosing a horse that is already showing concerning signs. The challenge is recognizing when your horse is entering a stressful period and putting a prevention plan in place before discomfort becomes the question hanging over every ride.

Why It Keeps Happening
Every Stress Event Is a Risk — and Your Horse's Stomach Never Stops Producing Acid
The problem is not that you have failed to manage your horse carefully. UlcerGard® works by reducing the production of acid in your horse's stomach, and the label points to the same stretches of the calendar you already circle: trailering, showing, training, racing, and injury rehabilitation. Those are the stressful conditions the FDA-approved label names. A demanding schedule stacks several of them at once. A long haul, unfamiliar surroundings, a training block that steps up, and days away from a normal routine can all land in the same weekend. Good management matters, and it still may not remove every stressor from that week. The uncertainty gets harder when subtle signs appear. Decreased appetite, recurrent colic, intermittent loose stools or diarrhea, a poor hair coat, poor body condition, or poor performance may point to stomach ulcers — but the label is clear that those signs can also be associated with other diseases. If your horse is showing one or more of them, that is a call to your veterinarian for diagnosis and treatment, not a reason to reach for a preventive. So you are balancing two responsibilities at once: protecting a healthy horse through predictable stress, and never mistaking a real health change for travel nerves or a difficult day. The answer has to fit that narrow space — labeled prevention before the stressful stretch, and prompt veterinary guidance the moment your horse tells you something may be wrong.
- ✗A long haul to the show you've been pointing at all season
- ✗Three days in a stall at a venue your horse has never seen
- ✗A training block that steps up faster than his routine does
- ✗Rehab confinement after an injury
The Solution
UlcerGard® — The Only OTC Formula With a Proven Prevention Claim
UlcerGard® is an FDA-approved omeprazole paste intended for use only in the prevention of stomach ulcers in healthy horses. It works to reduce the production of acid in your horse's stomach, and it is the only non-prescription formula proven to prevent Equine Gastric Ulcer Syndrome — no veterinary prescription required. The dosing is built for daily use during the stressful conditions the label names: trailering, showing, training, racing, and injury rehabilitation. Each tube contains four daily doses for horses weighing 600 to 1,200 lbs. A horse in that range gets one dose per day, as marked on the syringe. A horse over 1,200 lbs gets two doses per day. Giving it is straightforward. Deliver the daily dose marked on the tube on the back of your horse's tongue or deep in the cheek pouch. If any of the dose is lost or rejected, the label recommends re-dosing. The paste is cinnamon flavored, so there's nothing to mix and nothing to hide in feed. UlcerGard® may be used in breeding stallions. Safety in pregnant mares has not been determined, so let your veterinarian guide you there. Most importantly, UlcerGard® keeps prevention and treatment clearly separated. It's for healthy horses heading into a stressful stretch — not for a horse already showing decreased appetite, recurrent colic, loose stools, a poor coat, poor condition, or poor performance. Those signs need a veterinary diagnosis, because they may be associated with ulcers or with another disease entirely. From a family-owned equestrian retailer trusted since 1948.

These FDA-approved omeprazole pastes have different labeled purposes. UlcerGard® is an over-the-counter preventive for healthy horses, while GastroGard® and Gastrobim® are prescription products labeled for treating diagnosed gastric ulcers and preventing recurrence. Consult your veterinarian when your horse shows possible clinical signs.

What Makes UlcerGard® Different From Feed-Through Ulcer Supplements
Most ulcer supplements on the market work by coating the stomach lining or buffering acid — they do not address the source of acid production. UlcerGard® contains omeprazole, a proton pump inhibitor that shuts down acid secretion at the cellular level. That distinction is why it's the only over-the-counter product that carries an FDA-approved prevention claim.
The patented paste formulation guarantees stability and consistency dose to dose — you get the same effective amount in the first squeeze and the last. It's suitable for use in breeding stallions and is recommended for horses exposed to any of the stressors that drive ulcer formation: trailering, competition, intensive training, racing, or injury rehabilitation.
Note: Safety in pregnant mares has not been determined. If your horse already shows clinical signs of ulcers, consult your veterinarian — treatment may require prescription-strength omeprazole before switching to a prevention protocol.
