What is a common medication used for treating worms in horses?

Ivermectin is a broad-spectrum antiparasitic medication that is widely used for treating a variety of parasitic infections, including worms in horses. It is effective against many types of internal parasites, including strongyles and ascarids, as well as external parasites like lice and mange.

This medication works by disrupting the nervous system of the parasites, leading to their paralysis and eventual death. Its ease of administration, often available in a paste or injectable form, has made it a popular choice among horse owners and veterinarians for deworming protocols.

While other medications listed have their own specific uses—such as Fenbendazole for certain types of worms, Pyrantel for a broader range of nematodes, and Praziquantel primarily for tapeworms—Ivermectin stands out for its widespread effectiveness across multiple parasite types, making it a common go-to option in equine health care.
