Your horse could be “suffering in silence” with equine stomach ulcers.

Your horse can’t tell you when he’s suffering from equine stomach ulcers, also called Equine Gastric Ulcer Syndrome or EGUS. This painful, potentially life-threatening1 condition can affect most horses — of all ages, breeds and disciplines.


Only your veterinarian can accurately diagnose equine stomach ulcers, but you can help. Watch your horse for common signs of stomach ulcers and report them to your veterinarian as soon as possible. This will help you respond quickly and reduce pain and serious damage to your horse.


Your veterinarian can accurately diagnose and treat equine stomach ulcers.

Your veterinarian will use an endoscope or other proven techniques to diagnose equine stomach ulcers. If diagnosed, your vet will probably prescribe GASTROGARD® (omeprazole). GASTROGARD is the No. 1 veterinarian-recommended product for treating stomach ulcers2 — and the only medication that’s proven and approved by the FDA to treat equine stomach ulcers.
