Broad-spectrum parasite control for your horse from a respected source. Ivermectin-based oral pastes are the original patented formula for thorough parasite control. Unlike generics that control 35 species and stages of worms and bots, both Zimecterin® pastes protect your horse from 60 combined species and stages of equine parasites. Each syringe treats up to 1250 lbs. Convenient 250-lb increments ease use. Zimecterin® contains 1.87% ivermectin in a 0.21 oz dosing syringe. Controls strongyles, bots, small bloodworms, ascarids, threadworms, pinworms, hairworms, lungworms, and large mouth stomach worms. Safe for broodmares, stallions, and any age foal.
