🤦♂️ Side effects 🤦♂️
Over the last 12-18 months we’ve had several horses treated for Equine Gastric Ulcer Syndrome (EGUS).
The symptoms can be complex and numerous, as are the causes. However we only tend to be seeing a very nasty side effect, that directly impacts our job.
Equine Omprazole aka, GastroGard and UlcerGard. Is commonly the treatment we hear of the most. By suppressing the production of stomach acid, it allows the gut to heel.
I will attach a link about the drug here

It’s a very interesting read, and well worth looking at the side effects.
It’s been proven that over the course of the treatment, magnesium and calcium are significantly indigestible. This in turn has a significant impact throughout the body, including the feet.
A few good footed horses I’ve shod for a period of time showed a rapid decline in hoof quality and strength. In some cases completely falling apart, unable to hold shoes on for more that 3-4 weeks and increased shoe loss, with significant damage sustained.
The more I see horses having the treatment, the more I see these side effects.
I’ve recently asked for feedback from other farriers have seen a significant amount of horses showing the same symptoms. Some even suggesting more extreme symptoms such as laminitis .
Whilst there is very little farriers can do regarding the treatment of ulcers it’s important to discuss the side effects, and adapt the shoeing plan accordingly whilst treatment is ongoing.
I’ve attached 2 pictures of a young mare that up until her treatment, had some of the best feet I’ve seen. You can see a significant change in hoof quality half way down the hoof capsule , and extensive bruising. The structural integrity of the hoof is compromised, with no noticeable landmarks of the solar surface ie, whiteline, hoof wall and bars. Which is apparent in all 4 feet.
Luckily this owner is incredibly vigilant and her management is where it needs to be to recover well 🤞
I’d be interested if anyone here has also noticed Changes similar to these pictures, in their own horses .
