Giving Ivermectin up to 9 times the recommended dose does not cause toxicity in horses

Ivermectin for horses was introduced way back in early 80’s. Since then it has revolutionized parasite control in animals. Ivermectin paralyzes equine parasites by interfering with the function of gamma-amino-butyric acid (GABA). A neurotransmitter unique to invertebrates. This makes the deworming agent safe to use. Moreover, the coverage of parasites it is able to eliminate is just impressive. It is used to treat and control the growth of both large and small strongyles, ascarids, pinworms, hairworms, bots, lungworms, large-mouth stomach worms, summer sores and intestinal threadworms.

Ivermectin and resistance

The popular use of ivermectin dewormer together with other anthelmintics still require sensible use and application of wormer rotation. This is a strategy that helps horse owners to avoid the development of drug resistance from the parasites. Parasites are less likely to develop drug resistance to ivermectin when compared to other deworming agents.

When rotating different class of dewormers, also keep in mind that rotating products too frequently can also make parasites resistant not just to one deworming agent but to more than one. Parasitologists recommend that rotation should not be done more often than annually. For instance, one can use ivermectin dewormer for one year, and pyrantel pamoate for the next year, and the like. On the other hand, other researchers believe that the efficacy of dewormers will depend on various factors. These include; the most prevalent species of parasites in a specific location and a particular season of the year. Fecal egg counts are recommended by veterinarians. So it will be easy for them to develop a good worming program that is effective for your horse.
