Each syringe division delivers sufficient paste to treat 100kg of bodyweight (corresponding to 1.07g product and 20mg ivermectin). Each syringe delivers 140mg ivermectin, sufficient to treat 700kg of bodyweight.

The horse’s weight should be accurately determined to ensure use of the correct dose of product.

The animal’s mouth must be free of food. The syringe should be placed between the front and back teeth and the paste deposited at the base of the tongue. Immediately elevate the head for a few seconds to ensure that the product is swallowed. Re-treatment should be carried out according to the epidemiological situation and at not less than 30 day intervals. Eraquell may be used in pregnant mares.

Contra-indications, warnings, etc

For animal treatment only.

Not to be used in mares producing milk for human consumption.

Some horses carrying heavy infection of Onchocerca microfilariae have experienced reactions with swelling and itching after treatment. It is assumed to be the result of death of large numbers of microfilariae.

These signs resolve within a few days but symptomatic treatment may be advisable.

Eraquell has been formulated specifically for use in horses. Dogs and cats may be adversely affected by the concentration of ivermectin in this product, if they are allowed to ingest spilled paste or have access to used syringes.

As ivermectin is extremely dangerous to fish and aquatic life, treated animals should not have direct access to surface water and ditches during treatment.

Wash hands after use.

Avoid eye contact.

Do not smoke or eat while handling the product.

Dosage and administration

Single oral administration.

200 µg of ivermectin per kg of bodyweight corresponding to 1 tablet per 100 kg bodyweight.

To ensure a correct dosage, bodyweight should be determined as accurately as possible.

Once the correct dose has been determined, it should be administered in the following way :

Present the tablet in the palm of your hand.

Presenting one tablet at a time makes it easier for the horse to accept it, however the administration of multiple tablets at once is also possible.

Repeat this gesture until the complete dose has been administered.

During the initial administration, the tablet can be combined with a small amount of food or a treat to increase the acceptance by the horse.

In the event that the required dose is not ingested an alternative treatment should be administered. Seek the advice of your veterinary surgeon.

The veterinary surgeon should give advice regarding appropriate dosing programmes and stock management to achieve adequate parasite control for both roundworm and bot infestations.

Contra-indications, warnings, etc

Do not use in foals under 2 weeks of age. Do not use in horses known to be hypersensitive to the active ingredient or any of the other ingredients.

Colic, diarrhoea and anorexia have been reported in very rare occasions post treatment, in particular when there is heavy worm burden. In very rare occasions, allergic reactions such as hypersalivation, lingual oedema, urticaria, tachycardia, congested mucus membranes, and subcutaneous oedema have been reported following treatment with the product.

Special precautions for use in animals

Avermectins may not be well tolerated in non target species. Cases of intolerance are reported in dogs, especially Collies, Old English Sheepdogs and related breeds or crosses, and also in turtles and tortoises.

Dogs and cats should not be allowed to ingest spilled tablet or have access to used packaging due to the potential for adverse effects related to ivermectin toxicity.

Young foals, miniature horses and toy breeds weighing less than 50 kg may be unable to ingest tablets. Seek the advice of your veterinary surgeon.

Special precautions to be taken by the person administering the veterinary medicinal product to animals

Wash hands after use. Avoid contact with the eyes. In case of eye irritation, seek medical attention. Do not eat, drink or smoke while handling this product. In the event of accidental ingestion, seek medical advice and show the leaflet to the physician so that he knows what you have taken.

Special warnings for target species

Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in ineffective therapy: too frequent and repeated use of anthelmintics from the same class over an extended period of time, underdosing, which may be due to underestimation of body weight, misadministration of the product, or lack of calibration of the dosing device (if any).

Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. Faecal Egg Count Reduction Test). Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.

Resistance to ivermectin has been reported in Parascaris equorum in horses. Therefore the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

The product is safe for use in stallions.


A tolerance study performed with the product in adult horses with doses up to 5 times the recommended dosage did not show any adverse reactions.

Safety studies were conducted with a veterinary medicinal product containing praziquantel and the same dose of ivermectin (EQUIMAX oral gel), in mares, stallions and foals.

Administration to mares at 3 times the recommended dosage at 14-day intervals during the whole gestation and lactation periods did not result in any abortion, nor any adverse effect during gestation, at parturition or on the mares general health, nor any abnormality in the foals.

Administration to stallions at 3 times the recommended dosage did not show any adverse effect in particular on the reproductive performances.

Administration to foals with doses up to 5 times the recommended dosage did not show any adverse reaction.

Withdrawal period: Horses may be slaughtered for human consumption only after 35 days from the last treatment. Not to be used in horse producing milk for human consumption

Container disposal: Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal products should be disposed of in accordance with local requirements. EXTREMELY DANGEROUS TO FISH AND AQUATIC LIFE. Do not contaminate surface waters or ditches with the product or used container.

Q & A

Below are some recent questions we've received regarding Eraquell Horse Wormer, including answers from our team.

Donkey wormers

Sam M

Eraquell is apparently recommended by the donkey sanctuary yet your product description infers it is licensed for only horses. If it is, can you suggest an alternative. My donkey has a high count and had panacur 5 in the early spring. Thank you

  • Website Content Developer

Hi Sam,

Eraquell should be suitable for a donkey but if you send an email to our vet ([email protected]) she will confirm this.

Best wishes,

Can this wormer be used for mares with foals at foot?

  • Non-Executive Director

Yes this is safe for use in lactating mares.

24 May 2015 at 6:16pm



Does it get rid of pinworm?

  • Non-Executive Director

That is a good question. This wormer is licensed as a suitable treatment for Pinworm (Oxyuris equi) but in fact it is not very effective by itself. Effective pinworm treatment is more complicated than that. Medicated washes and enemas are sometimes used as well as an oral wormer, due to the location and life cycle of the worm. It is advisable to avoid sharing grooming equipment too. It is best to talk to your vet about this, or perhaps read about it online. There is a lot more to it than just using the wormer.

Time till worming next

Laura Gale

How long until the next worming if you use eraquell as it states you can't worm again until after thirty days but not what the normal period would be for it to last? As most are twelve weeks.
Yours thankfully
Laura Gale

  • Non-Executive Director

As a general guide, wormers are usually given to horses every 3 months. However it is best to tailor a worming programme to an individual horse if possible, taking into account where it is kept and how many horses share the grazing etc. Most worm doses actually only last a day or two in a way. They kill most or all worms present in the horse at the time the dose is given. The worming drug is then lost from the body and the horse will gradually start to pick up worms again, even within a few days. A small number of worms do no harm and are entirely natural for horses to have. If these build up to a high level, there is a much greater chance of them causing trouble. Hence it is usual to worm periodically to prevent this. However it is not quite true to think of the wormer lasting for the entire interval between worm doses, just that there is no need to keep worming more often than that.

If possible you should send a dung sample to a lab and test for worm eggs. Some horses do not need worming because they are on pasture which is not heavily contaminated with worm eggs and/or they can develop a good immunity to worms themselves. Others can rapidly build up a worm burden and need regular, effective worming. See the guides available on this page.

Is Equarell effective against red worm

Gayle Tyler

Can you tell me if equarell is effective against ed worm as it doesn't specifically mention red worm. Thank you

  • Brand Manager

Eraquell is effective against adult and immature redworm but not the encysted larvae which may be hibernating in the gut wall. The product will kill emerging redworm larvae though. Redworm are referred to as 'Cyathostomum spp.' in data sheets.

If you are concerned about encysted redworm larvae, I would recommend using a product containing moxidectin, like Equest or Equest Pramox (Pramox also contains praziquantel to kill tapeworm and is ideal for use in spring or autumn). Alternatively, a five day course of Panacur Equine should also be effective against larvae in the gut wall.
