Product Summary:

Quest Plus® Gel Wormer (moxidecin/praziquantel)
by Zoetis, formerly Pfizer

Quest Plus® Gel Wormer not only covers the largest range of worms but also suppresses strongyle egg production. It's an excellent solution to use on those horses that seem immune to other wormers. Just one dose treats and controls encysted small strongyles, bots and roundworms. It also contains the additional active ingredient praziquantel for efficacy against tapeworms. Each sure-dial syringe is calibrated in increments to help prevent overdose.


  • Combines 2% moxidectin and 12.5% praziquantel for the treatment and control of large and small strongyles, encysted cyathostomes, ascarids, pinworms, hairworms, large mouth stomach worms, stomach bots, and tapeworms
  • Treats encysted small strongyles, tapeworms, and bots (per AAEP Parasite Control Guidelines)
  • Broad spectrum, effective and safe
  • One dose also suppresses strongyle egg production through 84 days
  • For oral use in horses and ponies six months of age and older
  • Syringe calibrated in 50 lb. increments to help prevent overdose
  • Treats up to 1,500 lb. body weight
Item Specifications:

0.4 oz. (11.6g) gel
Syringe is approximately 4" with a 1/2" tip

Administration and Dosage:
Quest Plus® is specially formulated as a palatable gel that is easily administered to horses and ponies. It is packaged in ready-to-use SURE-DIAL® syringes. Each syringe is calibrated in 50-pound increments, up to 1500 pounds. This enables the administration of the recommended dose level by choosing a setting consistent with the animal’s weight.

It is part of my deworming rotation and very effective.

Based on low egg counts, Littleton Large Animal recommends this wormer or Zimectrin Gold for spring and Equimax for fall. Reviews of this product state the incidence of low side effects vs. Zimectrin Gold.

With Bimectin, equivalent to Equimax + Quest, but less expensive
