Panacur granules, how much ?


I would like to worm a 700kg /750kg ish horse over 5 days with panacur as I believe this is the gentlest was to do it as I believe he hasn’t been wormed in many years? I will need to use granules as the liquid bottle only goes up to 600kg I am struggling to work out how much of the granules to feed each day? Thanks

  • VioVet Staff

It is safest to worm for the highest possible weight, so 750kg. The dose is 5g per 150kg weight, which means you will need to give 25g of panacur which is 2 and a half sachets.
This can be done as a one off dose for routine worming or once daily for 5 consecutive days if you wish to cover against migrating strongyles/encysted redworm. However worms only migrate/encyst during the colder (Winter) months so this may not be necessary currently.

If your horse hasn't been wormed for a while then you may want to consider covering tapeworm too, Panacur will not cover tapeworms. A combination wormer containing ivermectin and praziquantel will do this such as Noropraz.
I recommend reading our guide on horse worming for a complete plan of what to do throughout the year, link provided here.

How much?

Valli Hayes

I have 2x11.2 and a12.2pony i want to worm for 5 days how much panacur guard liquid will I need ? Many thanks

  • VioVet Staff

This depends on your horse's weight. The most accurate way to find this out is inputting your horses heartgirth and bodylength into our calculator in our blog, link below:
Horse Weight Estimate

You can guess the weight from the hands too as stated on the above blog. An 11.2 hand horse will be roughly 200-240kg and a 12.2 hand horse will be 250-310kg. Panacur is dosed at 5ml per 65kg, so your 11.2h horse will need roughly 18mls once daily for 5 days, and your 12.2h horse 23mls.

Using these estimates you need 205mls of panacur in total, one bottle should be just enough.

Is the panacure 5 day wormer suitable for donkeys?

  • VioVet Staff

Yes, Panacur Guard is one of the few wormers licensed for use in Donkeys. It is important to worm for encysted red worm over winter which this product is effective against.

Confused on Dosage

Nichola Elliott

Following on from my question yesterday, ( I have 3 horses to be wormed. What would be the cheapest and with the least amount left over way to worm them. Pony A weighs 250kg pony B weighs 250kg and horse C weighs 450kg. I'm thinking one bottle of suspension and sachets to make up the difference? Thanks)

sorry should have made it clearer, I'm looking to worm against encysted redworm so understand I need the 5 day treatment? All worm counts clear for last 12 months and used equest promox last winter. What do you recommend? Or can I use equest again. Thanks

  • VioVet Staff

In that case you are right- you will need the 5 day course to treat for encysted red worm. Since you treated with Equest last year it would be better to switch to Panacur this year as you intend. The cheapest way (though you can check for yourself) looks like buying two bottles of the oral suspension taking into account that the ponies will need around 100mls each for the course and your horse will need roughly 175mls over the 5 days. If you buy two bottles you should only have 75mls left over which you may find is useful in case of any wastage.

Panacur 5 day guard against Pin worm


I have been advised by my vet to give my horse 1 bottle of panacur guard 3 weeks apart for 3 treatments. For pin worm. Is this correct and or safe or a bit over the top. My thoroughbred is 20 years old and I can't seem to get rid of the pinworm.

  • VioVet Staff

Pin worm can be very persistent and is more difficult to kill effectively since it lives in the rectum at the end of the gut. Most wormers are absorbed higher up in the gut and do not reach the rectum in high enough concentrations to be effective. Wormers such as Strongid P or Pyratape P containing the active ingredient Pyrantel tend to reach the rectum in higher concentrations than other wormers and so most effectively killing pinworm. I would agree with your vet that a series of treatments are required- I would do at least 2 treatments 2 weeks apart but a third treatment may be required if you are still seeing clinical signs. It is possible for your vet to take a sample from around the anus using sellotape and placing this on a slide to check for pinworm eggs which will give you an indication as to whether you have eradicated the worms. I have also used an Ivermectin and Propylene Glycol wash applied around the anus to kill eggs that have been laid there. Otherwise cleaning around the anus daily is helpful to remove eggs.

Which panacur product ?


hi I have a 13 hand Welsh cob who has had a worm egg count which it has been found to be high in strongyle eggs . I would like to know which panacur product would be the best to give over a five day program ? I think the wormer that he has had in the past has failed to protect him from this type of parasite .

  • VioVet Staff

There is some resistance to worming products in the horse population generally. It is also true that many horses are under-dosed so the worm doses given have no chance of being properly effective. This encourages resistance to develop too, with the surviving worms being selected for their ability to survive a worm dose, then they re-populate the horse(s) again from eggs on the pasture.

Panacur might well be effective if given at the correct dose. It does not really matter so much which one you give, they all contain the same active ingredient (= fenbendazole). Panacur is mosts effective if given daily for 5 days, which is the usual way of giving Equine Guard 10% Supension. You need to give 5ml of the product per 65 kg bodyweight daily for 5 days. If you could do a worm egg test a week or so after this is done, you could see if Panacur is fully effective or not in your horse. Whatever product you use, you should try to establish the weight of your horse as accurately as possible and give an adequate dose. It is actually better to give an over-dose than an under-dose with Panacur. Even if you gave a double dose it would be very safe.
