Product Overview

There are several possible causes of equine stomach ulcers, including travel, training, competing, limited turnout, grazing, or even just a simple change in routine.1 lf your horse has been diagnosed with stomach ulcers, GASTROGARD® (omeprazole) can help with the healing process. The unique omeprazole paste formulation protects the omeprazole as it works through the system for adequate absorption. GASTROGARD® is the only equine ulcer treatment that is approved by the FDA and proven to be safe and effective.

IMPORTANT SAFETY INFORMATION

The safety of GASTROGARD® (omeprazole) paste has not been determined in pregnant or lactating mares. For use in horses and foals 4 weeks of age and older. Keep this and all drugs out of the reach of children. In case of ingestion, contact a physician. Caution: Federal (USA) law restricts this drug to use by or on the order of a licensed veterinarian. For additional information, please refer to the full prescribing information.

GASTROGARD® is for the treatment and prevention of recurrence of gastric ulcers in horses and foals 4 weeks of age and older.
For use in foals (4 weeks old and up; 600 pounds or more) and horses.

Nieto JE, et al. Comparison of paste and suspension formulations of omeprazole
GASTROGARD® (omeprazole) is a proton pump inhibitor that regulates the final step in hydrogen ion production and blocks gastric acid secretion regardless of the stimuli. The drug works to reduce the amount of acid in the horse’s stomach, thus increasing the gastric pH to foster healing of ulcers. GASTROGARD incorporates a special paste formulation to protect the omeprazole from stomach acid as it travels to the small intestine to be absorbed.

GastroGard® (omeprazole) Paste for horses contains 37% omeprazole and is available in an adjustable-dose syringe. Each syringe contains 2.28g of omeprazole. Syringes are calibrated according to body weight and are sold in individual 6 g tube.
Boehringer Ingelheim
A gastroscopy should be performed by a licensed veterinarian to diagnose gastric ulcers prior to starting on this medication.
For treatment of equine gastric ulcers, GASTROGARD® (omeprazole) should be administered orally once-a day for 4 weeks at the recommended dosage of 1.8 mg omeprazole/lb body weight (4 mg/kg). For the prevention of recurrence of gastric ulcers, continue treatment for at least an additional 4 weeks by administering GASTROGARD at the recommended daily maintenance dose of 0.9 mg/lb (2 mg/kg). GASTROGARD is recommended for use in horses and foals 4 weeks of age and older. The contents of one syringe will dose a 1250 lb (568 kg) horse at the rate of 1.8 mg omeprazole/lb body weight (4 mg/kg). For treatment of gastric ulcers, each weight marking on the syringe plunger will deliver sufficient omeprazole to treat 250 lb (114 kg) body weight. For prevention of recurrence of gastric ulcers, each weight marking will deliver sufficient omeprazole to dose 500 lb (227 kg) body weight. To deliver GASTROGARD at the treatment dose rate of 1.8 mg omeprazole/lb body weight (4 mg/kg), set the syringe plunger to the appropriate weight marking according to the horse’s weight in pounds.
To deliver GASTROGARD at the dose rate of 0.9 mg/lb (2 mg/kg) to prevent recurrence of ulcers, set the syringe plunger to the weight marking corresponding to half of the horse’s weight in pounds.
To set the syringe plunger: 

1) While holding plunger, turn the knurled ring on the plunger ¼ turn to the left and slide the knurled ring along the plunger shaft so that the side nearest the barrel is at the appropriate weight marking, aligning the arrows on the ring and plunger.      

2) Lock the ring in place by making ¼ turn to the right. Ensure it is locked. Make sure the horse’s mouth contains no feed. Remove the cover from the tip of the syringe, and insert the syringe into the horse’s mouth at the interdental space. Depress the plunger until stopped by the knurled ring. The dose should be deposited on the back of the tongue or deep into the cheek pouch. Care should be taken to ensure that the horse consumes the complete dose. Treated animals should be observed briefly after administration to ensure that part of the dose is not lost or rejected. If any of the dose is lost, re-dosing is recommended. If, after dosing, the syringe is not completely empty, it may be reused on following days until emptied. Replace the cap after each use.

Suellen S Verified Purchase
February 26, 2018

Recommended by my vet when we discovered (after scoping him) that my OTTB has severe ulcers. Vet does NOT recommend generic or compounded omeprazole because the lack of FDA oversight means they may or may not actually contain the right amount of the drug. So this is expensive, but it will give a consistent result.

I my geldingbwas diagnosed as having ulcers, no problem I figured I'll just get the GastroGard from the vet. The vet told me to buy it online for a more reasonable price. Allivet's price was about 2/3 less than my Vet or local sources. Plus it shipped and arrived in 2 actual days, not 3 or 4 for processing etc. I'll buy again from Allivet.

Very impressed with the staff at Allivet. They were courteous, expedient and handled my order exceptionally well. The order arrived without any delays and our horse is doing better after only 2 weeks on the medication. We elected to order from Allivet as it was $ 7.50/tube less than what our Veterinarian was charging. Thank you once again, Allivet, for your excellent service.

Wonderful price and packaging. Paid extra for expedited shipping, but it took 2 days before it was shipped (despite great responsiveness from prescribing vet) defeating the purpose of not having to purchase from local vet at much higher price for the first few tubes of total regimen.

This product is the only product that controls my horse's acid. While it is expensive, Allivet offers it at the least expensive price. The pharmacy is easy to work with, and the cost is far less than treatment in a large animal hospital! Would highly recommend this product if your horse suffers from ulcers.

This was the best price I found for gastrogard. And site was recommended by my vet. I was pleased with service representatives but as this was my first order there seems to have been confusion with how to link the script my vet called. But that may have been me. I did not see where to enter my customer number When I created my account. Think it would have been better if I set up my act before the vet called in the script.
