Use UlcerGard paste for prevention of ulcers in your horse. 

2 out of 3 competitive horses have stomach ulcers. 
Makes sense. Wherever there is stress, there can be ulcers.

Equine Gastric Ulcer Syndrome (EGUS), stomach ulcers, is when sores on the stomach wall develop and are caused by excess acid. 

When you administer UlcerGard to your horse, you are giving that only medicine that is FDA approved and proven effective product for preventing ulcers.

Each UlcerGard paste syringe contains 2.28g of omeprazole just like GastroGard. Same ingredients as GastroGard. 4 doses per syringe.

The clinical signs of stomach ulcers include, but may not be limited to:

  • Weight Loss
  • Altered Eating Behavior
  • Recurrent Colic
  • Change in Attitude
  • Sub-optimal Performance
  • Diarrhea
  • Dull Coat
If your horse experiences stress due to changes in routine, diet, and exercise regimens that come with confinement, training, travel and competition; ask your veterinarian about proactive ulcer prevention with ULCERGARD® before treatment is ever warranted.


  • The minimum recommended dosage is 1/4 syringe or 1 mg/kg per day (0.45 mg/lb). 
  • When given once daily during the stressful period, ULCERGARD has been shown to effectively prevent stomach ulcers in horses. 
  • This effect was tested in horses exposed to stressful conditions for either 8 or 28 days.

Stomach ulcers are more common in horses than once believed. Studies have demonstrated stomach ulcers in over 90% of racehorses and 60% of performance horses in various disciplines. Horses secrete acid in their stomach 24 hours a day. Horses on grass pasture or eating large quantities of roughage infrequently develop stomach ulcers. Horses without continual access to roughage or in rigorous training are at greater risk of stomach ulceration due to the effects of acid on the stomach lining. The additional stresses of traveling, competition, stall confinement, and strenuous exercise can also contribute to the development of stomach ulcers in horses.

ULCERGARD works to prevent stomach ulcers in horses. The active ingredient in ULCERGARD, omeprazole has been extensively tested for safety and effectiveness. It works by reducing the production of acid in the horse’s stomach. To help horses maintain optimal gastric health, it is recommended that ULCERGARD be administered during stressful events or activities that may induce stomach ulcers. Such conditions may include: training, racing, showing, traveling, stall confinement, and competition.
