Prevention is the best medicine when it comes to stomach ulcers, which can reduce your horse’s performance and can even lead to death.1

Horses are extremely sensitive to stress. Even events that many horse owners consider to be routine can be stressful enough to contribute to stomach ulcer development, sometimes in as few as five days.2 In addition to travel,3 training3 and competition3, changes in routine, 4 illness or injury, 5 and limited turnout or grazing5 can cause stomach ulcers. And unfortunately, horses with stomach ulcers often suffer in silence before they are diagnosed and the horse owner never knows it.

You guard your horse against injuries. You guard against disease. With UlcerGard, you can guard against equine stomach ulcers. UlcerGard is the only product that’s approved by the FDA to prevent equine stomach ulcers.* Best of all, it’s easy to use. Your veterinarian can supply you with UlcerGard and discuss management tips that also can help reduce the stress factors that cause stomach ulcers.

*When treated for eight to 28 days, UlcerGard is proven to effectively prevent gastric ulcers in horses exposed to stressful conditions.

Important safety information:

UlcerGard can be used in horses that weigh at least 600 pounds. Safety in pregnant mares has not been determined.

Your horse can’t tell you when he’s suffering from equine gastric ulcer syndrome. This painful, potentially life-threatening condition1 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. Signs may include changes in drinking and eating behavior, weight loss, change in attitude, recurrent colic, change in haircoat and less than optimal performance.2 Watching for and reporting these signs will help you respond quickly and reduce pain and serious damage to your horse.

Your veterinarian can accurately diagnose, treat and heal 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. GastroGard is the No. 1 veterinarian-recommended product for treating stomach ulcers3 — and the only medication that’s proven and approved by the FDA to treat equine stomach ulcers.

How common are equine stomach ulcers? Equine stomach ulcers have been found in horses of a wide variety of breeds, disciplines and ages, including:

  • 93 percent of racehorses4
  • 63 percent of nonracing performance horses5
  • 51 percent of foals5

Important safety information:

Safety of GastroGard in pregnant or lactating mares has not been determined.

Equioxxis the first and only coxib NSAID approved for horses and provides 24 hours of prescription pain relief* in just one daily dose.1 Other NSAIDs must be given multiple times a day to provide consistent, round-the-clock therapeutic levels of pain relief – possibly leaving horses vulnerable to a roller coast effect of pain and pain relief.2,3,4

Equioxxis the only NSAID approved for use for up to 14 consecutive days by both AQHA and the United States Equestrian Federation when used at the recommended dose at least 12 hours prior to competing.5,6

An important part of a product’s effectiveness is that it be used properly. Convenient administration of the product is also essential. According to 95 percent of horse owners in a study, Equioxxdelivers a unique combination of properties that make it convenient to use: 7

  • Once daily dosing8
  • Palatable oral paste formulation9
  • Well accepted by 98 percent of horses10
  • Can be used with all nonbreeding horses at least 1 year old8
  • Can be administered with or without feed or hay8

Important Safety Information:

As with any prescription medication, prior to use, a veterinarian should perform a physical examination and review the horse’s medical history. A veterinarian should advise horse owners to observe for signs of potential drug toxicity. As a class, nonsteroidal anti-inflammatory drugs may be associated with gastrointestinal, hepatic and renal toxicity. Use with other NSAIDs, corticosteroids or nephrotoxic medication should be avoided. Equioxxhas not been tested in horses less than 1 year of age or in breeding horses, or pregnant or lactating mares.
