All good so far but to early to assess the regimen just yet. But but I found the granules easier to administer to my horse as it can be mixed more readily into the feed.

Panacur 5 day for red worms?


Does a 5 day dose of Panacur treat for all the same worms as Equest Pramox and in particular encysted red worms?

  • VioVet Staff

Using Panacur at it's 5 day course dose will treat for encysted redworm. It will not cover tapeworm like Equest Pramox will as it does not contain praziquantel. Essentially it will cover all the same worms Equest Pramox does apart from tapeworm.

Dosage for foals



Please can you advise correct dosage for foals as using the granules specifically for roundworm at this age. (Foal in question, at 16 weeks will be just over 200kg)

Thank you

  • VioVet Staff

The dose for Panacur Granules as per the datasheet is as follows:
Foals and ponies up to 300 kg bodyweight: 1 sachet
Fenbendazole within Panacur is a very safe medication, I advise following the datasheet regarding doseage.

Alpaca wormers


I have been told their is no license wormers for alpacas
I read panacur is suitable for a Alpaca i was just wondered if that was correct and if you knew what dosage I should give them
I see so many panacur with different animals on are they all the some just different doses

many thanks

  • VioVet Staff

There are no licensed wormers for Alpacas, you are right. Most vets will advise using wormers off license for the species. Unfortunately we cannot offer off license advice as an online pharmacy. Your vet can recommend appropriate products and doseages, as well as write prescriptions for them for you. I advise discussing this with them.

Tara Kier

Can the panacur 5 day guard be added to the horses feed rather than via syringe? I assume it can be purchased syringe or liquid.

Thank you

  • VioVet Staff

Yes Panacur Guard (sachet, liquid or paste) can be given in the feed. If you need help with specific doseages then please get in touch with us at [email protected].

Most economic

Anne Allen

I have 8 Shetland ponies ranging in weight from 120 kegs to 250 what is the most economic way to worm
Panacur. Liquid or paste for 5 day worming

  • VioVet Staff

Each bottle of 225ml Panacur treats up to a 585kg horse for a full 5 day course. The Panacur syringe only treats up to 600kg horse for just 1 day of the 5 day course. If you are doing the 5 day course it is always more cost efficient to purchase the 225ml bottles, unless you are only treating 1 horse weighing a maximum of 100kg. The paste is more cost effective though for a 1 off worming dose.

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.
