6 x 33g Multi-dose syringes.

(30 days treatment dose or 60 days prevention dose.)

PHARMACOLOGY Omeprazole is a proton-pump inhibitor.

Omeprazole suppresses gastric acid by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of the parietal cell. Omeprazole will block gastric acid secretion irrespective of the stimulus.

Maximum acid suppression occurs after 3-5 days of treatment.


Clinical signs of gastric ulceration include depressed appetite or inappetence, recurrent colic, intermittent loose faeces, chronic diarrhoea, poor hair coat, poor body condition or poor performance. Signs in foals include depressed appetite or inappetence, teeth grinding, dribbling saliva, diarrhoea, sternal recumbency or weakness.

For accurate diagnosis direct endoscopic examination of the gastric mucosa is recommended.


Ulcershield has a wide safety margin in horses and foals and can be used in foals from one month old.

Ulcershield can be safely administered to stallions used for breeding. Safety in pregnant or lactating mares has not been established. The safety of Ulcershield for longer than 91 days treatment has not been determined.


Ulcershield can be used concomitantly with other medications including anthelmintics, antibiotics, non-steroidal anti-inflammatories and other commonly administered veterinary preparation.


After administering the initial dose use remaining product within 1 month.
