Each syringe holds an apple-cinnamon flavored paste containing 100 mg of fenbendazole per gram, an anthelmintic believed to work by inhibiting energy metabolism in susceptible internal parasites. The syringe barrel has a rotating dial that is set to the horse's current body weight, allowing a measured dose to be deposited on the back of the tongue through the interdental space. A carton holds five 57-gram syringes, providing one dose per day for five consecutive days, the schedule used to reach a larvicidal dose against encysted small strongyle larvae. No assembly is needed beyond removing the syringe tip cap before dosing. The paste is formulated for horses of any age, including foals, weanlings, pregnant mares and breeding stallions, and is intended for oral use only. Syringes should be stored at or below 77 degrees F (25 degrees C) and kept out of reach of children and animals. Horses treated with this product are not intended for human consumption.
