Treating Stomach Ulcers in Horses

At HorsePrerace, we specialize in supplements, vitamins, and other treatment solutions that will improve the quality of life and overall well-being for your hard working horse. If you need ulcer medicine for horses, we offer a wide selection of products that are used to quickly and effectively deliver needed relief to your valued equines. Horses are highly susceptible to developing gastric ulcers, and failing to address the condition can result in a potentially life-threatening situation down the road.

The main causes of stomach ulcers in horses are:

Type of Food: If you provide your horse with foods that are difficult to chew, your horse will have to produce more saliva to comfortably swallow the roughage. Saliva is a natural acid-neutralizer and can help balance the stomach without having to resort to additional treatment options or supplements. But horses that consume soft foods that don’t demand much in the way of chewing may suffer from an acidic stomach - and the likelihood of ulcers goes up at the same time. The calcium levels in various foods is an important consideration, too. Alfalfa, for instance, is high in the mineral calcium, which also acts as an effective acid neutralizer.

Feeding Cycle: For thousands of years, horses have lived in the wild and their bodies adapted to a lifestyle of grazing throughout the day. The stomach of a horse produces acids on a continual basis to properly manage the steady food intake of a grazing animal - but most horses today are fed on a time schedule that is nothing like they’re used to in the wild. This means that stomach acids are working around the clock, potentially damaging the lining of the horse’s stomach when there isn’t sufficient food to act as a barrier. Acids build up quickly, and ulcers form in no time.

Exercise: Your horse or racing animal is lucky to receive exercise and training sessions, but when horses don’t train on a consistent cycle their bodies tend to metabolize foods faster. This means that their stomachs are left empty during period of acid production - potentially creating ulcers. Horses that do train on a regular basis process foods slower, reducing the chances of stomach acids pooling and ulcers developing.


Most of the popular ulcer treatments available on the market today minimize inflammation in the stomach or esophagus and minimize the amount of acid being produced in the stomach. This combination greatly reduces the likelihood of long-term damage to the digestive system and certainly helps the horse feel better. There are several options available today, including:

Omeprazole Paste: As one of the faster and more effective options on the market today, Omeprazole is popular with trainers because it shuts down excess acid production in a horse’s stomach in a matter of days. According to recent studies, 93% of racehorses suffer from stomach ulcers, so it pays to stock up on Omeprazole or your preferred ulcer treatment solution.

Ranitidine Powder: Dogs, camels and horses can benefit from Ranitidine powder, as it acts as a potent histamine H2-receptor antagonist that quickly reduces inflammation in the stomach and esophagus. Humans use a form of Ranitidine powder, too, but horses also see nearly immediate relief from heartburn and the pain related to peptic, gastric, and colonic ulcers.

Misoprostol Powder: Horses that suffer from unrelated health conditions like muscle sprains, ligament damage or joint issues are often given NSAIDs (non-steroidal anti-inflammatory drugs) for pain-relief. But overuse of these pain-killers can seriously erode the horse’s stomach lining, increasing the chances of ulcers in the delicate lining of the stomach. This treatment option is a synthetic form of prostaglandin and comes in a convenient powdered form.


If you see your horse frequently grinding its teeth, witness a noticeable and shift in body weight, see a change in disposition or overall demeanor, or your horse is not eating as well as it used to, we have gastric ulcers in horses treatment options. However, your ulcer medicine for horses solution should always be with the consideration of the services of a veterinarian to ensure your horse is in top condition. If it is, rest comfortably knowing that you have a resource at your fingertips that can provide the supplements and medicine needed to counteract the effects of gastric ulcers in horses.
