What It Is and How It Works
Ivermectin is an antiparasitic medication that works by interfering with the nerve and muscle functions of parasites. It binds to certain chloride channels in these parasites, increasing permeability and leading to paralysis and death. This effectively reduces the parasite\’s population, helping to manage infections in horses.
Indications / Uses
Ivermectin horse paste is approved for the treatment of various parasitic infections in horses, such as large and small strongyles, pinworms, roundworms, and bots. It is crucial for maintaining the health and performance of horses by keeping parasite loads to a manageable level.
Off-label use for humans has been widely discouraged by health authorities due to the formulation not being suitable for human use and the lack of evidence supporting its safety and efficacy in human parasitic infections.
Dosage Forms and Typical Dosing Considerations
Ivermectin horse paste is available as a single clear paste containing 1.87% ivermectin. Dosage is typically determined based on the horse’s weight, with the paste being administered orally according to instructions provided by veterinarians.
