Quest 11.3g

Quest 11.3g


Just one dose of QUEST® Gel treats and controls encysted small strongyles, bots and roundworms. QUEST contains an additional active ingredient — praziquantel — for efficacy against tapeworms. The American Association of Equine Practitioners (AAEP) recommends tapeworm treatment in the late fall or early winter after tapeworm transmission ends due to cold weather.1

One syringe of QUEST now treats up to 1,500 pounds. Dewormers remain the same trusted formulations. Use a scale or weight tape prior to each deworming to help ensure an accurate dose for your horse.

Since 2008, veterinarians and horse owners have purchased more than 16 million tubes of QUEST.



Small strongyles are the key parasite of concern for adult horses.1 This equine parasite has shown widespread resistance to fenbendazole. Moxidectin, the active ingredient in QUEST and QUEST PLUS, continues to show efficacy.3



QUEST are the only FDA-approved products to suppress the production of small strongyle eggs, and a study showed egg suppression persisted for 90 days.2 This residual parasite control reduces pasture contamination and provides a period of protection from reinfection for horses and ponies.
