RE: [RC] Ivermectin - heidiLibby said: Does anyone else remember when Ivermectin first came out there was an injectable form? It was taken off the market because too many horses died form an allergic reaction to their sudden dead worm load. We lost one. Thank god it wasn't a clients. Janelle replied: Isn't the injectable the liquid still on the market but it is prescription and you use it as a drench? We use this and I like it because I can dose the horse more accurately and not have 2/3 used tubes of paste left over. Also, the horse can't spit it out like paste. Death due to an allergic reaction to the die-off of a large worm load can happen with just about any dewormer. That said, the reason why the injectable ivermectin approved for horses was removed from the market was not due to anaphylaxis related to worm die-off, but rather was due to the fact that for some reason, the injection sites were particularly prone to clostridial contamination, and without meticulous site prep, several horses died of clostridial infection (which causes gas gangrene). It was for this reason that the horse labeling for the injectable was pulled. The injectable form does not require a prescription--it is simply not approved for equine use. You can buy it OTC for cattle or swine at purtnear any livestock supply. However, since the injectable form is exactly the same stuff as the oral form used for horses, many horse owner opt to buy the (much cheaper) cattle injectable to give orally to horses. (I am one such person myself--with 40+ horses to deworm, the cost savings of buying the cattle injectable version as opposed to the various equine preparations is significant.)
