Overview
First Companion EquiStrength Pyrantel Pamoate Paste is a 23.6 g oral paste dewormer for horses, providing effective control of large and small strongyles, pinworms, and roundworms (Parascaris equorum) through the anthelmintic action of pyrantel pamoate. Pyrantel pamoate works by causing spastic paralysis of susceptible worms, leading to their expulsion from the GI tract. As one of the three primary anthelmintic classes used in equine deworming programs (alongside ivermectin/moxidectin and fenbendazole), pyrantel pamoate plays an important role in rotation-based deworming strategies — helping to reduce the development of anthelmintic resistance by alternating drug classes. Pyrantel is particularly valued for its efficacy against small strongyles (cyathostomins) and is safe for use in horses, including pregnant mares and foals as young as 8 weeks. The calibrated, weight-adjustable syringe allows precise dosing based on body weight. Each 23.6 g tube treats one average-sized horse.
