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.
All prices include VAT where applicable.
EQUEST Oral Gel contains 18.92 mg/g moxidectin. Also contains 37.84 mg/g benzyl alcohol and 0.24 mg/g disodium edetate as preservatives.
Moxidectin is a second generation macrocyclic lactone of the milbemycin family.
For the treatment of infections caused by moxidectin sensitive strains in horses and ponies:
Strongylus vulgaris (adults and arterial stages)
Strongylus edentatus (adults and visceral stages)
Triodontophorus brevicauda (adults)
Triodontophorus serratus (adults)
Triodontophorus tenuicollis (adults)
Small strongyles (adults and intraluminal larval stages) (small redworms):
Parascaris equorum (adult and larval stages)
Pinworm: Oxyuris equi (adult and larval stages)
Stomach worm: Habronema muscae (adults)
Bots: Gasterophilus intestinalis (L2, L3)
Bots: Gasterophilus nasalis (L2, L3)
Threadworm: Strongyloides westeri (adults)
Hairworm: Trichostrongylus axei
EQUEST Oral Gel has a persistent efficacy of 2 weeks against small strongyles. The excretion of small strongyle eggs is suppressed for 90 days.
EQUEST Oral Gel is effective against (developing) intramucosal L4 stages of small strongyles. At eight weeks after treatment early (hypobiotic) EL3 stages of small strongyles are eliminated.
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.
Do not administer to young foals less than 4 months of age.
Do not administer in case of known hypersensitivity to the active ingredient or to any other milbemycins and to any other ingredients of the veterinary medicinal product.
EQUEST Oral Gel has been formulated specifically for use in horses only. Dogs or cats may be adversely affected by the concentration of moxidectin in this product if they are allowed to ingest spilled gel or have access to used syringes. Neurological signs (such as ataxia, muscle tremor and convulsions) and digestive clinical signs (such as hypersalivation) were recorded.
Do not use the same syringe to treat more than one animal unless horses are running together or in direct contact with each other on the same premises.
Ataxia, depression, abdominal pain, muscle tremor, flaccid lower lip and swelling of the muzzle could be observed on very rare (less than 1 animal in 10,000 animals treated, including isolated reports) occasions. These adverse effects are usually transient and disappear spontaneously in most cases.
Meat and offal: 32 days.
Do not smoke, drink or eat while handling the product.
The use of protective gloves is recommended.
Wash hands or any exposed area after use.
Avoid direct contact with skin and eyes.
In the event of eye contact, flush the eye with copious amounts of clean water and seek medical advice.
Moxidectin fulfils the criteria for a (very) persistent, bioaccumulative and toxic (PBT) substance; therefore, exposure of the environment to moxidectin must be limited to the extent possible. Treatments should be administered only when necessary and should be based on faecal egg counts or evaluation of the risk of infestation at the animal and/or herd level. In order to reduce the emission of moxidectin to surface water and based on the excretion profile of moxidectin when administered as the oral formulation to horses, treated animals should not have access to watercourses during the first week after treatment.
Like other macrocyclic lactones, moxidectin has the potential to adversely affect non-target organisms:
After opening, use within 6 months.
Do not store above 25°C.
Keep the syringe in the carton.
After first use record the date to be disposed on the label space provided.
Any unused veterinary medicinal product or waste material derived from such veterinary medicinal products should be disposed of in accordance with the local requirements. Do not contaminate watercourses with the product. The product is toxic for fish and aquatic organisms.
Keep out of the sight and reach of children.
For animal treatment only.
Propylene syringe containing 14.8 g of gel with a graduated plunger and cap.
EQUEST Oral Gel is effective against benzimidazole resistant strains of cyathostomes.
Mares may be treated at any stage of pregnancy and lactation.
Adverse reactions may occur at twice the recommended dose in foals and 3 times the recommended dose in adults. The symptoms are depression, inappetence, ataxia and flaccid lower lip in the 8 to 24 hours following treatment. Symptoms of moxidectin overdose are the same as those observed in very rare occasions at the recommended dosage. In addition, hypothermia and lack of appetite may occur. There is no specific antidote.

Below are some recent questions we've received regarding Equest Horse Wormer, including answers from our team.
can this wormer be used on pregnant mares?
Thank you for your question,
This is suitable for use on pregnant and/or lactating mares.
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.
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.
Can you tell me which horse wormer should I use in July? and would Equimax tablets be suitable? Thank you
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.
Can this product treat ringworm
No this product won't treat ringworm. The name ringworm is misleading- it is actually a fungus. You will need Imaverol to treat ringworm.
Is this wormer suitable for a 6 month foal, if not , which should I use. He has pin worm
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.

When treating encrusted red worm which product would you recommend for mares in foal?
And also lactating mares with foals at foot
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.
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?
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.
advice at worming in-foal mare at this time of year, what product can i use she is 5 months in foal
We suggest Equimax as it is safe to use in pregnancy, Equimax treats round worm and tape worm.
You can find Equimax here
I hope this helps, if you have any further enquiries, please do not hesitate to contact us.
Is the equest wormer a double dose wormer
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).
We went away to the new forest a week ago and noticed a bot fly had laid eggs on both ponies. We removed as many of the eggs we could see. What wormer and how long after should we worm. If at all.
This is a good wormer for bot fly larvae. Personally I would suggest dosing 7-14 days after leaving the New Forest. Ideally remove all the eggs as soon as you are aware of them of course.
