UlcerGard Review: Omeprazole for Ulcer Prevention in Horses

The one genuinely proven product in a category full of guesswork, and the reasons to speak to your vet before you use it.

The verdict: Omeprazole in a cinnamon-flavoured oral paste, licensed in the United States as a non-prescription preventive for equine gastric ulcer syndrome, which makes it one of very few products in this aisle with a proven mechanism. Use it for the situations it is licensed for, such as travel, competition and other predictable stress. Do not use it to treat a horse you suspect already has ulcers, because prevention and treatment are different doses and treatment is a veterinary decision.

Specifications

Specifications above come from UlcerGard's published product information. Treat pricing as approximate, since Amazon pricing moves.

What it does well

• Omeprazole has a proven mechanism and a substantial evidence base in horses, which distinguishes it sharply from the herbal and buffering products it sits beside on the shelf.
• It is licensed specifically for prevention during predictable stress: travel, competition, stall confinement and changes in routine.
• A paste syringe is straightforward to administer and does not depend on the horse eating a supplement.
• Cinnamon flavouring, which materially improves the odds of a horse accepting it.
• Non-prescription in the United States, so it can be kept on hand for a planned journey rather than requiring a vet visit each time.

Where it falls short

• Prevention is not treatment. UlcerGard is licensed and dosed for prevention; treating an existing ulcer is a different dose over a different duration and is a veterinary decision. Using a preventive dose on a horse with active ulcers under-treats it.
• Ulcers are diagnosed by gastroscopy. Guessing from behaviour is unreliable, because girthiness, poor appetite and grumpiness have many causes, several of them more serious. If you believe your horse has ulcers, ask your vet about scoping.
• Suppressing stomach acid is not a neutral act. Acid has a purpose, and long-term suppression has been raised in the veterinary literature as having its own consequences, including for hindgut health and mineral absorption. Long-term use should be a vet's call.
• It does nothing about the cause. Ulcers in horses are driven by long gaps without forage, high starch diets, stress and confinement. A horse standing twelve hours without hay will make more ulcers as soon as the omeprazole stops.
• The economics matter. Preventive dosing through a long competition season is expensive, which is another reason to be sure the horse needs it rather than dosing on suspicion.

What owners report

Owner reports on omeprazole are among the most consistently positive of any equine product, and that consistency is unusual enough to be worth noting: unlike most of this category, the mechanism is understood and the effect is real.

Where reports become mixed is around recurrence. Owners repeatedly describe symptoms returning once dosing stops, which is exactly what you would expect if the management that caused the ulcers has not changed. That pattern is the most useful thing in the owner literature and it points at forage, turnout and diet rather than at the syringe.

Who it suits

• Horses facing predictable stress: long journeys, competition, box rest or a change of yard.
• Owners working with a vet on a horse with a diagnosed ulcer history.
• Anyone whose vet has recommended preventive dosing around a specific event.

Who should skip it

• Anyone treating suspected active ulcers without veterinary involvement. That needs a diagnosis and a treatment dose.
• Owners using it as a substitute for management change, since ulcers recur when the cause does not change.
• Horses with vague symptoms nobody has investigated, where the real problem may be dental, metabolic or musculoskeletal.
