Prevents Stomach Ulcers By Reducing Acid Production

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.

1) To set the syringe plunger, while holding plunger, turn the knurled ring on the plunger 1/4 turn to the left and slide the knurled ring along the plunger shaft so that the side nearest the barrel is at the appropriate daily dose marking, aligning the arrow on the plunger with the notch on the ring, as shown in the pictogram.

2) Lock the ring in place by making 1/4 turn to the right. Ensure it is locked (it should no longer slide).
