This veterinary medicinal product is effective in horses of various breeds and under
different management conditions; foals as young as four weeks of age and weighing
over 70 kg; and breeding stallions.
Treatment of gastric ulcers: one administration per day during 28 consecutive days at
the dose rate of 4 mg omeprazole per kg body weight followed immediately by a
dosage regimen of one administration per day during 28 consecutive days at the
dose rate of 1 mg omeprazole per kg body weight, to reduce the recurrence of gastric
ulcers during treatment.
Should recurrence occur, re-treatment at a dose rate of 4 mg omeprazole per kg
body weight is recommended.
It is recommended to associate the treatment with changes of husbandry and training
practices. Please see also the text under section 3.5.
Prevention of gastric ulcers: one administration per day at the dose rate of 1 mg
omeprazole per kg body weight.
To deliver the veterinary medicinal product at the dose of 4 mg omeprazole/kg, set
the syringe plunger to the appropriate dose division for the horse’s weight. Each full
dose division on the syringe plunger delivers sufficient omeprazole to treat 100 kg
body weight. The contents of one syringe will treat a 575 kg horse at the rate of 4 mg
omeprazole per kg body weight.
To deliver the veterinary medicinal product at the dose of 1 mg omeprazole/kg, set
the syringe plunger to the dose division equivalent to one quarter of the horse’s body
weight. At this dose, each full dose division on the syringe plunger will deliver
sufficient omeprazole to treat 400 kg body weight. For example, to treat a horse
weighing 400 kg, set the plunger to 100 kg.
Replace cap after use.

excipients.

Special precautions for safe use in the target species:
This veterinary medicinal product is not recommended for animals under 4 weeks of
age or weighing less than 70 kg body weight.
Stress (including high performance training and competition), feeding, management
and husbandry practices may be associated with the development of gastric
ulceration in horses. Individuals responsible for the well-being of horses should
consider reducing the ulcerogenic challenge by modifying husbandry practices to
achieve one or more of the following: reduced stress, reduced fasting, increased
intake of roughage and access to grazing.

product to animals:
As this veterinary medicinal product may cause hypersensitivity, avoid direct contact
with skin and eyes. Personal protective equipment consisting of protective clothing
including impervious gloves should be worn when handling the veterinary medicinal
product. Do not eat or drink when handling and administering the veterinary
medicinal product. Wash hands or any exposed skin after use. In case of contact with
eyes, wash immediately with clean running water, seek medical advice and show the
package leaflet or the label to the physician. Persons developing a reaction after
contact with the veterinary medicinal product should avoid handling the veterinary
medicinal product in future.
Special precautions for the protection of the environment:
