GastroGard 370 mg/g Oral Paste for Horses
GastroGard 370 mg/g oral paste for horses contains omeprazole. This medicine reduces acid production in the horse’s stomach. Vets use it to treat and help prevent equine gastric ulcers.

How GastroGard Works
GastroGard 370 mg/g oral paste for horses contains omeprazole, a proton pump inhibitor. It acts on the acid-producing cells in the stomach.
The medicine reduces the amount of acid released. Less acid means less irritation to the sensitive stomach lining. This gives existing ulcers a better chance to heal. It also helps protect the stomach when horses face stress, travel or intense work.
When Vets Use GastroGard
Your vet may prescribe GastroGard 370 mg/g oral paste for horses when:
• Gastric ulcers are confirmed
Gastroscopy shows ulceration in the stomach lining.
• Ulcers are strongly suspected
History, signs and response to previous treatment suggest gastric ulcer disease.
• A horse is at high risk
The horse is in hard work, travels often or cannot have constant access to forage.
Your vet will examine your horse and may recommend scoping to confirm the diagnosis and monitor healing.
How to Give GastroGard Paste
GastroGard 370 mg/g oral paste for horses is supplied in oral syringes with a plunger and dose markings.
Your vet will:
-
Weigh or estimate your horse’s bodyweight
-
Set the correct dose and course length
-
Show you how to set the plunger and give the paste
The paste is usually placed on the back of the tongue. Give it exactly as your vet instructs. Do not skip doses or stop early unless your vet advises.
If your horse spits out some of the paste, or you are unsure a full dose was taken, contact your vet for guidance before giving more.
Ulcer Management and Support
GastroGard works best as part of a complete management plan. Alongside treatment, your vet may suggest:
-
More frequent forage and reduced time with an empty stomach
-
High-fibre diets with controlled cereal and starch levels
-
Steady training plans rather than sudden changes in work
-
Turnout or lower-stress routines where possible
-
Careful use of other medicines that can affect the stomach
Good management helps reduce ulcer risk in the future. Always discuss diet and workload changes with your vet.
Safety Information
