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

Present the tablet in the palm of your hand. 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 practitioner.

Advice regarding appropriate dosing programmes and stock management should be sought to achieve adequate parasite control for both tapeworm and roundworm infestations.

Contra-indications, warnings, etc

For animal treatment only.

Do not use in foals under 2 weeks of age.

Do not use in mares from which milk is taken for human consumption.

Do not use in horses known to be hypersensitive to the active ingredients or any of the other ingredients.

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 in a number of countries including ones in the EU. Therefore the use of this product should be based on national (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics

The product can be used safely in stallions.

Can be used during pregnancy and lactation.

Special precautions for use in animals

Avermectins may not be well tolerated in all 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 tablets or have access to used packaging due to the potential for adverse effects related to ivermectin toxicity.

Operator Warnings

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. Keep out of the reach of children. In the event of accidental ingestion, seek medical advice and show the leaflet to the physician so that he knows what you have taken.

Adverse reactions

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 and urticaria, tachycardia, congested mucus membranes, and subcutaneous oedema have been reported following treatment with the product.

Withdrawal Period

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

Q & A

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

12 May 2018 at 8:00pm



Does this treat for pinworm?

  • Veterinary Advisor

In theory the active ingredient in Equimax, Ivermectin, is effective against pinworm. However pinworm are found right at the end of the gastro-intestinal tract in the rectum. When you worm your horse most of the Ivermectin is absorbed higher up in the gut and does not reach the rectum in quantities high enough to be effective against pinworm. I would suggest using a Pyrantel based wormer such as Pyratape P or Strongid P at double the dose for treatment of pinworm.

Does equimax gel treat red worm

  • Veterinary Advisor

Yes, Equimax treats adult red worm which is fine for most of the year. However it does not treat encysted redworm. Redworm larvae become encysted in the wall of the intestine over the winter. You should therefore treat with Equest or Panacur over the winter which are effective against encysted red worm.

Combined wormer

Tim Hawkes

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

I've been advised based on worm egg count to use combined wormer, is this suitable for this time of year?

  • Veterinary Advisor

Yes Equimax is a good choice for this time of year. It contains Ivermectin and Praziquantel and will treat redworm and tapeworm. It would be a good idea to treat with Equest or Panacur in late December for encysted red worm larvae.

What worms this product covers

Janet Turner

  • VioVet customer since 2016
  • From: , United Kingdom

does this product also cover red worm ?... can see this does cover roundworm, lungworm, Bots and tapeworm but for redworm would I need a different type of wormer, thanks

  • Veterinary Advisor

Ivermectin (one of the active ingredients of Equimax) is effective against adult red worm. However during the winter redworm larvae become encysted in the wall of the intestine. Ivermectin is not effective against the encysted redworm so you should use Equest (Moxidectin) or Panacur (Fenbendazole) over the winter to treat encysted redworm. However at this time of year the larvae will not yet be encysted so Equimax is ideal as it will treat tapeworm also.

Catherine Hobbs

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

Can i turn my horse out after giving them Equimax?

  • Veterinary Advisor

Yes that is fine. There is no evidence to suggest that keeping horses in after worming is beneficial. The best way to control worms is to allow normal turn-out routines and poo pick the paddocks regularly.

4 March 2016 at 6:33pm



Which wormer is safest to use on an old pony (40+) that has not many teeth and not been on a regular worming plan?
Thank you

  • Non-Executive Director

Most modern wormers are very safe and so this is not really a great concern. Having said that, Panacur is sometimes regarded as one of the mildest, least potentially toxic wormers, so you could try that. Have you tested for worm eggs on a dung sample? Some older horses need very little worming anyway?

22 October 2014 at 10:44pm

Horse has only taken partial dose of Equimax tablets


I only managed to get my horse to eat 4 of the 6 tablets he needed. Is it best to try to get him to take the other two the next day or wait for a period, do a worm count and then if necessary use a different product?

  • Non-Executive Director

I would go for your second suggestion. The lower dose might have been adequately effective. If not, you are more likely to encourage ivermectin resistant parasites by repeating the same product so soon. If an egg count demonstrates a significant mature worm infestation then a different product would be my suggestion. (Tapeworms do not show on egg counts so if you are worried about this a blood test could be done. Tapes are not usually a big concern and the lower dose given might well be effective for them anyway - they are easily killed off by the praziquantel in the wormer.

18 June 2014 at 1:58pm

Period between doses

Jan Bottomley


Can anyone tell me the time period between doses, ie once they have been dosed with this wormer, when are they next due to be wormed with another wormer, I cant find any information about this?

  • Brand Manager

Equimax is ideal for worming in spring and autumn to cover tapeworm and a wide range of roundworm and bots.

If your horse is over 6 years old, they should have built up a natural immunity to most adult roundworm and may not need worming over summer. We would recommend that you carry out a faecal egg count to see if they need treating- it is a cheap and you can buy the kit needed here and then you send it off in a pre-paid envelope.

In winter, it is recommended that you target encysted small redworm larvae, which do not show up on these faecal egg counts. Target these in winter with a single dose of either a moxidectin product or a five day course of a fenbendazole product to prevent mass emergence in spring.

Approach to worming has changed in recent years due to worms building a resistance to the chemicals used, so each horse would ideally be treated based on their individual needs.

We have a guide to worming your horse (with an example worming plan) if you would like to read more about the topic, and feel free to contact me for further information.
