Equest contains moxidectin and is one of the few wormers licensed to control the important encysted larval stages of small red worms. It has a long period of anti-worm activity after the dose has been given (13 weeks) and so helps to reduce pasture contamination. Equest is also less toxic to the natural beetles and other insects which help to break up the dung on the pasture, compared with ivermectin-based products. This means that pastures tend to remain cleaner and healthier where the dung is not collected from the field.

The presence of worms can be checked in your horse using a Worm Testing Kit.

If tapeworm control is also needed, then Equest Pramox has to be used, which contains the additional ingredient praziquantel.

Horse lice


Will equest wormer kill lice on horses?

  • VioVet Staff

Equest will not kill lice, it is a wormer. If you are looking for an over the counter lice product then we advise Deosect.

I need a wormer for encysted redworm

Maureen Long

  • VioVet customer since 2018
  • From: Derbyshire, United Kingdom

I was advised Noromectin would treat encysted red worm but I can't seem to get hold of any will Equest do it. My horse has been on the few programme and has a very low count for other worms.

  • VioVet Staff


Thank you for your question,

Our E-SQP states that Noromectin has no effect on encysted small redworm. Equest (and Equest Pramox) are the only wormers that have effect on this. As you said your horses tested low, there is a new blood test available that has just been released for detecting encysted small redworm. Speak to your vet to see if they have signed up for the test to be available through them. This will be most beneficial for your horse as you may not need to give this treatment at all, especially if they have had low worm counts.

Thank you.

Horse wormers


Can you tell me which horse wormer should I use in July? and would Equimax tablets be suitable? Thank you

  • VioVet Staff

Hi Sue,

We have produced a worming guide for our customers which you can find here: https://www.viovet.co.uk/blog/p313-A_guide_to_worming

You would need to be worming for roundworm now so use a wormer containing fenbendazole or pyrantel.

I hope this helps.

What The product treats

Lile branniff

Can this product treat ringworm

  • VioVet Staff

No this product won't treat ringworm. The name ringworm is misleading- it is actually a fungus. You will need Imaverol to treat ringworm.

Rebecca Nash

  • VioVet customer since 2016
  • From: Dorset, United Kingdom

Is this wormer suitable for a 6 month foal, if not , which should I use. He has pin worm
Thank you

  • VioVet Staff

Equest can be used on foals from 6 months old. However I would suggest a Pyrantel based wormer such as Strongid P or Pyratape P at double the normal dose as the most effective treatment for Pinworm. Pinworm can be very persistent so you may need to repeat this again 2 or 3 times at 2 week intervals. It is also a good idea to clean around his bottom daily since the adult worms lay eggs around the anus- you may see a creamy white discharge.

Mares in foal

NATALIE REID (natalie050119)

  • VioVet customer since 2015
  • From: Gloucestershire, United Kingdom

When treating encrusted red worm which product would you recommend for mares in foal?
And also lactating mares with foals at foot
Many thanks

  • VioVet Staff

I would recommend using Equest for treatment of encysted red worm larvae over the winter. It is safe for use in pregnant mares and lactating mares with foals at foot. It is safe to give to foals from 4 months old.

Equest pramox or Equest + equi tape

Susan Croucher

  • VioVet customer since 2012
  • From: Cornwall, United Kingdom

I have used Equest and pramox in the past with no issues but took shoes off of one of my horses last October and have heard that the pramox sometimes makes barefoot horses 'footy' or laminitic due to the disruption of the gut. Would it be better to give her Equest followed by equi tape a few days/week later or would it make no difference in your opinion?

  • VioVet Staff

I think this will make no difference to her feet. You should choose your wormers based on other factors I feel. Ideally use faecal tests etc to determine likely worm burden, as some horses do not need such frequent worming. For others is it can be very important. Personally I would not get side-tracked down thinking about her hooves though.

Worming horses


Is the equest wormer a double dose wormer

  • VioVet Staff

No, you never need to give a double dose of Equest. You should give the standard dose, but do try to give this as accurately as possible according to the genuine weight of your horse. Giving an under-dose is not helpful and it is better to slightly over-dose in fact if you are not quite sure of the weight of your horse.

A double dose of wormer is sometimes recommended to treat tapeworms. Equest is perhaps the best wormer for all the important roundworms in horses, but it has no real effect on tapeworms at any dose. Ideally you should give a different ingredient for tapeworms. Using Equest Pramox is a good way of doing this and covers all worms (at a standard dose).
