Q & A

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

27 September 2019 at 4:50pm



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.

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.

Differences between Eqvalan and Eqvalan Duo

Jayne Fielding

Please can you tell me the difference between the two wormers and when I should use them?

  • VioVet Staff

Eqvalan contains ivermectin, which is effective against all roundworm including L4 stage encysted small redworm larvae (they hide in the gut wall and emerge in spring, causing colic if infestation is high). Ivermectin is also effective against botfly larvae 'bots'. Eqvalan Duo contains ivermectin AND praziquantel to target tapeworms as well as all roundworms and bots.

  • Eqvalan Duo should be used in spring (March/April) and autumn (September/October) to kill any tapeworm present among other worms and bots.
  • Eqvalan is ideal for targeted worming in winter (November to February) to rid the horse of  immature larvae, bots and roundworm and for strategic worming in the summer months (May-August) if required -indicated by a worm egg count.
  • Strategic worming involves sending off dung samples for an egg count, and only worming if the results indicate the horse has a high burden of worms. Horses naturally have immunity to some worms and a low level of infection is 'normal'.
