Ivermectin is a drug mixture of two structurally semisynthetic lactones that is used in veterinary medicine as an anthelmintic, boticide, acaricide, and insecticide. Ivermectin has a broad spectrum of activity against intestinal and insect parasites, and kills migrating larvae.¹ Ivermectin is widely prescribed by veterinarians in all horse deworming programs because of its efficacy.

Ivermectin is known to provide effective broad spectrum control of:

• Small strongyles, including those resistant to some benzimidazole class compounds (adults and fourth-stage larvae): Cyathostomum spp., Cylicocyclus spp., Cylicostephanus spp., Cylicodontophorus spp., Gyalocephalus spp., Triodontophorus spp. (adults)
• Intestinal threadworms (adults): Strongyloides westeri
• Pinworms (adult and fourth stage larvae): Oxyuris equi
• Ascarids (adult and third and fourth stage larvae): Parascaris equorum
• Hairworms (adult): Trichostrongylus axei
• Large-mouthed stomach worms (adult): Habronema muscae
• Neck threadworms (microfilariae): Onchocerca spp.
• Bots (oral and gastric stages): Gasterophilus intestinalis, G. nasalis²

Swelling and itching reactions after treatment with ivermectin have occurred in horses with heavy infections of neck threadworm microfilariae.¹ Since equine dewormers have been known to be toxic to dogs and cats, cleaning of barn aisles, wash-racks, etc. is recommended after administration, particularly in operations in which dogs and/or cats are known to be present.

Ivermectin 2% suspension (1000 ml) by NexGen provides a first-line deworming solution for your equines, and is safe for pregnant mares, breeding stallions, and foals of any age.
