The active ingredient in Quest is Moxidectin. It is effective against roundworms or ascarids, pinworms, large strongyles small strongyles, hairworms, stomach worms, Onchocerca cervicalis and bots. This is the only dewormer that kills dangerous encysted mucosal larvae (LL3 and L4) before they emerge. It is expected that the administration of QUEST Gel as per label directions can eliminate approximately 80% of the developing, encysted cyathostomes
When used at the recommended dose, suppresses strongyle egg production for up to 84 days following a single administration, thereby reducing pasture contamination and providing a period of protection from reinfection for equines grazing that pasture.
QUEST is a gel and dissolves rapidly in the horse’s mouth. This minimizes head-tossing and greatly reduces spit-out associated with paste dewormers. Coupling the gel formulation with the QUEST Sure-Dial syringe makes it easy to give your horse an accurate dose.
Weight measurements should be accurately determined to ensure the correct dose of QUEST is administered.
Do not use QUEST Gel or QUEST PLUS Gel in foals less than 6 months of age or in sick, debilitated and underweight horses. Do not use in other animal species, as severe adverse reactions, including fatalities in dogs, may result.
