You can get ULCERGARD through your veterinarian without a prescription.5 Each tube of ULCERGARD contains four daily doses for horses weighing 600 to 1,200 lbs.

Horse Weight Dose
Under 600 lbs. Consult your veterinarian
600 - 1,200 lbs. 1 dose per day
(as marked on the ULCERGARD syringe)
Over 1,200 lbs. 2 doses per day
  1. Before administering ULCERGARD, make sure the horse’s mouth contains no feed.
  2. Remove the cover from the tip of the syringe, and insert the syringe into the horse’s mouth at the interdental space.
  3. Depress the plunger until stopped by the knurled ring.
  4. The dose should be deposited on the back of the tongue or deep into the cheek pouch.
  5. Replace the syringe cap after use; remaining paste may be reused on following days until emptied.

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.


We followed the veterinarian’s advice and started giving Bootz ULCERGARD® (omeprazole) a couple of days before shows and during shows. During the 2012 show season, we didn’t have any of the problems we’ve had in the past keeping his weight on and with his willingness to work. And the only difference is that we’ve been giving him ULCERGARD.

Nicki seemed much more comfortable and willing to do his job following the treatment. We were just excited that the stomach ulcers wouldn’t keep him from living up to his potential. We really believe the use of ULCERGARD® (omeprazole) with our horse contributed to this incredible accomplishment.

I use ULCERGARD® (omeprazole) a few days before we leave for a show, and through the entire event. After all the work, time and effort that goes into getting these horses to their peak, I want to give them every advantage, and that includes preventing ulcers.
