Q & A

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

Encysted red worm

Rebecca anne calder

What wormer can be used this time of year to cover encysted red worm in donkeys

  • VioVet Staff

The only wormer licensed to treat encysted redworm in donkeys is Panacur (fenbendazole) when used at the 5 day course doseage. Equest (moxidectin) will treat this but it is not licensed for use in donkeys. it may be safe for use in donkeys but as this is an off license use of the medication you will need a written prescription from your vet to purchase it with us.
Eqvalan contains ivermectin and will treat redworm but not the encysted winter stage.

Can I give this product to a mare that will be nearly 5 months pregnant

Kirsty Bolton

  • VioVet customer since 2017
  • From: Denbighshire, United Kingdom

Can I give this product to a nearly 5 months pregnant mare (26 Sep 21 she will be 5 months) as when I go to order it says unsuitable even though in the advice section it says it is safe as long as over 3 months

  • VioVet Staff

The datasheet for these two wormers state the following:

Eqvalan Duo:
In the absence of clinical data in early pregnancy Eqvalan Duo can only
be used in the first three months of gestation according to a risk
benefit analysis by the veterinarian.

Horses and donkeys of all ages, including pregnant mares and breeding stallions, have been treated with no adverse effect.

Both products are therefore safe for use in your pregnant mare of 5 months gestation.

Donkey tapeworm wormer

Clive Tinsley

  • VioVet customer since 2018
  • From: Sir Gaerfyrddin, United Kingdom

Hi why do you not recommended duo for tapeworm in donkeys

  • VioVet Staff

Eqvalan is licensed for use in donkeys but Eqvalan Duo is not. This is because Duo has not been tested and proven safe for use in donkeys so we cannot dispense it for this use.
If you wish to cover tapeworms in your donkey then you can use a double dose of Strongid-P. This is licensed for use in donkeys.

Strongyles and small red

Katie Bell

My pony has tested for Strongyles and low level small red. Will Eqvalan treat both of these?

  • VioVet Staff

Yes, Eqvalan contains ivermectin which will treat both Strongyles and Small Redworm. It will not cover the encysted stages of small redworm however they only encyst during the winter months and ivermectin will be effective against small redworm in their current state.

Age of horse

La Cresswell

  • VioVet customer since 2017
  • From: Powys, United Kingdom

can Eqvalan be given to an 8/9 month old horse?

  • VioVet Staff

Yes Eqvalan is safe to use in an 8/9month foal. It can be used as early as 6 to 8 weeks of age according to the data sheet.

Is Eqvalan Duo flavoured to appeal to horses i.e. apple for example? I want to give it to my youngster in his feed.

  • VioVet Staff


Thank you for your enquiry.

Eqvalan Duo is one of the unflavoured horse wormers. Hopefully your youngster will not mind it being mixed into his food, however it is important to ensure that he receives the full dose in one go.

Noropraz is an ivermectin and praziquantel based alternative (same active ingredients as Eqvalan Duo) that is apple flavoured :)

I hope this helps!

Kind regards,

Double dose


Does the duo need to be given as a double dose to protect from tapeworm? Thanks

  • VioVet Staff

It is suggested that Pyrantel based wormers such as Pyratape P should be given at double the normal dose to treat for tapeworm. However the active ingredient against tapeworm in Eqvalan Duo is Praziquantel which does not require double dosing.

Is the Duo wormer safe for mares due to foal in 2 months time?


Is the Duo wormer safe for mares due to foal in 2 months time?

  • VioVet Staff

Yes Eqvalan Duo is fine to give to mares in foal after the first 3 months of pregnancy- not because it is unsafe but due to lack of clinical data in early pregnancy.

  • VioVet customer since 2014
  • From: Midlothian, United Kingdom

Hi I wormed my new pony last week I could only get strongid P from my local feed store anyway I found bot larvae in her stools can I worm again so soon and is this the wormer I should use?Thanks

  • VioVet Staff

Eqvalan is effective against bots. It is also a very different type of wormer to Strongid P and so it is fine to use again after just 1 week.

What worms do these kill?

Peter Canning

What worms do these kill? Which ones are most important?

  • VioVet Staff

Eqvalan will kill both adult an immature stages of many types of worms (a full list can be found on the data sheet in our description section) but there are two main groups we need to target- roundworms (nematodes) and tapeworms (cestodes). Roundworms include ascarids which most horses develop a good immunity to before in their first few years but have the potential to be very damaging in the first year of life, so routine worming is vital for the young animals. Of two types of redworm, large strongyles are now rare and do not often cause a problem as they are easily controlled. Small redworm (cyathostomes) on the other hand are much more difficult to control and may cause severe colic in spring as their larvae emerge from their dormant phase in the lining of the gut. It is important to target these larvae in winter months or early spring. The L3 'hibernating' or 'encysted' larvae are resistant to most wormers but when they emerge, the L4 stage larvae are killed by the ivermectin in Eqvalan. Eqvalan also remove pinworm infestations.

We would advise sending off regular dung samples for egg counts, as worming when it is not needed promotes development of resistance in the roundworms. You should also be certain of your horse's weight, and a weigh tape is a simple way to calculate this.

Eqvalan Duo also contains praziquantel to kill tapeworms such as A.perfoliata. It is considered okay to routinely treat for tapeworm in spring and autumn with Evalan Duo.
