Northwest Equine Veterinary Associates has been treating horses with IRAP® since its approval in the United States nearly 10 years ago with very promising results and many happy success stories.
This product does not have the cartilage-damaging effects that can be seen with intra-articular corticosteroids and is frequently effective when corticosteroids are no longer effective in a particular joint. Additionally, IRAP® is very effective in managing osteoarthritis in horses for which corticosteroids are contraindicated, as in horses with PPID (equine Cushing’s disease).
Initiating therapy with IRAP® involves an initial blood draw followed by a series of three injections spaced 7-10 days apart. After completing the initial series, many horses are able to be maintained with a single IRAP® injection in each affected joint every 6-12 months.
