Quest Gel contains moxidectin, an antiparasitic medication that interferes with nerve signaling in susceptible parasites. According to its FDA-approved labeling, it is used for the control of large strongyles, small strongyles (including encysted cyathostomes), ascarids, pinworms, hairworms, large-mouth stomach worms and horse stomach bots in horses and ponies. A single dose also suppresses strongyle egg production through 84 days. The syringe is set to your horse's weight and the gel is given by mouth.
The actions described here reflect the product's FDA-approved labeling; your veterinarian determines the appropriate use for your animal.
Quest Gel is formulated for horses and ponies only and should not be used in other species, since severe reactions including fatalities can occur in dogs. Use a scale or weight tape to find your horse's weight before setting the dose. Use extreme caution in foals, young horses and miniature horses, because an overdose can cause serious reactions. Do not use it in sick, debilitated or underweight animals, and watch very young or debilitated animals for transient depression or loss of coordination. Store at or below 77°F, avoid freezing and keep partly used syringes capped tightly. Moxidectin can harm aquatic life, so dispose of the syringe properly. Not for human use. Keep out of the reach of children and wash your hands after handling.
