Once daily paste

Contains omeprazole 370 mg/g

For gastric ulcer treatment and prevention

Available as a 6-pack or single syringe

Contains: Omeprazole 370 mg/g (equivalent to 407 mg/mL)

Features and Benefits
Omeprazole is a proton-pump inhibitor and 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.
OMOGUARD is formulated with an oil carrier base to protect the Omeprazole from acid degradation in the stomach. On passage to the alkaline intestinal environment, the Omeprazole becomes biologically available and is rapidly absorbed into the bloodstream.

Treatment and prevention of gastric ulcers in horses and foals.
By suppressing acid production, OMOGUARD creates a more neutral gastric environment which reduces ongoing damage to the gastric mucosa and also allows improved healing of existing damage.
OMOGUARD is effective in horses under a variety of management conditions, including racing or showing, in horses and foals as young as one month of age.

Concomitant Therapy
OMOGUARD can be used concomitantly with other medications including anthelmintics, antibiotics, non-steroidal anti-inflammatories and other commonly administered veterinary preparations.

Dosage and Administration
Set the adjustable dose syringe to the required volume and ensure the horse's mouth is empty prior to administration. Place nozzle in to the side of the mouth and deposit paste far back between the teeth and cheek or over the back of the tongue. Immediately raise the horse's head for a few seconds after dosing to ensure the full dose is swallowed. Monitor the horse and if any rejection or loss of medication is suspected, re-dosing is recommended. Replace the cap after each use and store the syringe on its side.

Treatment: 4 mg/kg/day. Adult horse (600kg) 6 mL orally once daily for 28 days. (1 mL per 100kg).

Prevention: 2 mg/kg/day. Adult horse (600kg) 3 mL orally once daily for 28 days or longer. (0.5 mL per 100 kg).
Long-term treatment at the preventative dose rate is recommended to avoid recurrence of gastric ulcers.

30 mL (33g) adjustable multi-dose syringe. Available as a single syringe or 6-pack.
