Equest Horse Wormer is for the treatment and control of adult and larval stages of internal parasites, including small redworms, large redworms and bots in horses and ponies. If the recommended dose is given, it provides effective control of moxidectin sensitive strains of most common parasites.

Withdrawal Period is 32 days.

  • 1 x 14.8g Syringe

Key Benefits

  • Kind to the environment
  • Parasite control for horses
  • Long duration of action worming horses for 13 weeks


  • Active Ingredient
    18.92mg/g Moxidectin

For oral administration.

A single oral dose of 400 µg moxidectin/kg bodyweight using the calibrated syringe. Before the first dose, hold the syringe with the capped end pointing to the left and so that you can see the weight measurements and tick marks (small black lines). Set the syringe to zero by moving the dial ring so that the left side is set at the first full black mark and depress the plunger, safely discarding any paste that is expelled.

To dose the product, hold the syringe as previously described. Each tick mark relates to 25 kg bodyweight and to 10 mg moxidectin. Turn the dial ring until the left side of the ring lines up with the weight of the animal.

Use of a scale or weigh tape is recommended to ensure accurate dosing.

A single syringe treats a 700 kg horse.

To avoid overdosing, care should be taken to accurately dose foals, especially low bodyweight foals or young ponies.

What our vet says

What our vet says
"Worming your horse can be stressful for both of you if your horse is syringe adverse. But it's a vital job and someone's got to do it! A few tips - always know your horses weight, practice handling your horse's nose, have the correct dose ready to go, administer in an area which makes it easy to clean up any spills and wash your hands afterwards."
