I’ll always use panacur liquid wormer for my cat because he doesn’t mind having it in his food, plus, there’s little chance of overdose if the measurement is wrong, though obviously it never is, I’m careful of that. The only negative is, why isn’t there a syringe included? It would be so much easier than the measuring cup. Luckily I have a syringe. Good stuff though, my cat never has any negative side effects from having this.

I took my dog to the vets in December 2019 with chronic diarrhoea. The vet saw him and gave him half a dozen Digestive Support and a tube of pro-biotics without prescribing any drugs. Obviously, the digestive support and pro-biotics was only a temporary fix and his diarrhoea came back on and off for months after. His tummy started to bloat (with loud gurgle) and produced smelly farts. He started to vomit bile when that happens.
I contacted the vets again and it was suggested that I allowed them to do a poop test when I phoned them again in early May 2020. The dog's tummy got better after that phone call so there was no point doing the test then.
All this time, my dog's breath reeked really bad and someone thought it was his oral hygiene but I ruled it out as I was brushing his teeth daily.
My dog's tummy suddenly took a turn again on 20 July 2020 and this time the diarrhoea came back with a vengeance.
I did some research online and thanks to a load of very helpful resources online from experienced dog owners and vets, from his symptoms, I came to the conclusion that he is suffering from the nematode parasite known as Giardia.
I spoke to the vets again on 21 July and they refused to sell Panacur to me and insisted that I allow them to do a poop test. I knew it was going to be expensive and a time consuming process (I lost a dog previously because they had been messing me around too much) and diagnosis would be a hit and miss with the vets. I decided to take matters in my own hands and looked online to purchase this drug. Thankfully, I found it on Viovet and ordered it on 22 July 2020. It arrived on 25 July and and I started my dog on it immediately at 12 noon that day.
The diarrhoea carried on and was particularly bad on the early hours of morning on 27 July when I was woken up three times by the dog begging to go out to toilet. By the third dose on 27 July at 12 noon, like magic, the dog's tummy suddenly took a turn and the diarrhoea stopped after 3pm. This morning, 28 July, he produced a beautiful solid poop for me and I can tell you I was well pleased. His diarrhoea has not returned. His breath is no longer reeking of terrible odour and he is a happy dog!

I have started him on another product (ProKolin Advanced) which will help boost his digestive tract flora and bring his health back to speed. I will now have to bath the dog and wash everything in the house thoroughly. I would repeat of Panacur in 3 weeks' time to ensure that his system is 100% cleared of Giardia.

Caveat: My dog is MDR1 genetic deficient and he used to have Panacur paste for deworming as a puppy so I knew that he is not allergic to this drug. You need to be cautious when using this drug for the first time. Please follow instructions given in the leaflet and I find giving the drug for 3 consecutive days is good enough to eliminate Giardia even for extensive prolonged gut infestation as with my dog. There is no need to double the time to 6 days as some websites suggest.

Bottom line: Please pet owners, pay close attention your dog's breath. It shouldn't reek or have bad doggy breath cos if your dog has bad doggy breath, he is either ill or has dental problems.

British bulldogs worming


I have 2 bulldog puppies at 2 weeks old when should I worm them

  • VioVet Staff

The datasheet for this product recommends that 'Puppies should be treated at 2 weeks of age, 5 weeks of age and again before leaving the breeders' premises.'

Dosage query

Marie Roddis

  • VioVet customer since 2009
  • From: South Yorkshire, United Kingdom

my dog weighs 3.4kg. with regards to the panicur satches wich one would you recommend

  • VioVet Staff

If you are wanting to do a standard adult worming dose then I recommend giving one of the 1.8g (blue) sachets as this treats a 2.2kg to 4.4kg dog. If you are treating for other reasons then please get in touch with us at [email protected] so we can provide more tailored advice.

I use dronatal but understand that doesn’t cover giardiasis does panacur cover this please I have an adult male 21 kg dog.

  • VioVet Staff

Drontal does not have a license to treat Giardiasis unfortunately. Panacur does have a license against this, the dose is 50mg/kg once daily for 3 consecutive days according to the datasheet. Most veterinary literature recommend doing this for 5 days instead but as this would be off license it is done at your own risk.
The licensed dose for your dog would be 1 x Panacur 4.5g (red) sachet and 1 x Panacur 1g (yellow) sachet once daily for 3 consecutive days. This totals 3 x red and 3 x yellow sachets. If you are wanting to use the Panacur Oral Solution liquid then this would be 10.5mls once daily for 3 days. However this is a lot of liquid, the oral solution is better for smaller dogs/puppies so I advise using the granules instead.

Dosage required for Adult cats

Lise Thorngate

Dosage for an adult cat weighing 10kg

  • VioVet Staff

An adult worming dose according to the data sheet for a cat is as follows:

1 ml per 1 kg body weight as a single oral dose (= 100 mg fenbendazole/kg body weight).
So for a 10kg cat this is 10mls.

However I recommend reweighing your cat or checking that your scales is not in pounds, it is far more likely your cat weighs less than this. The average weight for a domestic cat is around 3.5kg to 4kg.
I also advise using Panacur granules instead as this will be easier to dose than the solution.

Worming tablet alternatives


Hi. Is there a broad spectrum liquid alternative to worming tablets? We have 2 cats that just won't eat any food with the current tablets crushed into it and it's not possible to insert direct into their mouths. We currently give Milbemax as they're meant to be palatable but no luck at all

  • VioVet Staff

Unfortunately there is no liquid wormer than will cover both roundworms and the most common species of tapeworms. Panacur covers roundworms but not the most common species of tapeworm. Your best alternative is using a spot on wormer, such as Dronspot. This is applied to the skin on the back of the neck similar to msot flea treatment.

Is a syringe included in the box?

  • VioVet Staff

There is no syringe included with this product, but a plastic dosing cup is included which can be used to measure out the correct quantity.
If you need a syringe then many can be found on our website. Please contact our customer services on [email protected] if you would like further advice on this.

Is this vet strength wormer


Are the wormers you sell the same as you get from the vets not the over the counter from pet shops

  • VioVet Staff

All of our medications, including the Panacur you are referring to, are official licensed medications. We source them from licensed wholesalers, exactly the same as your locat vet would.

Liquid wormer


Hi I have tried everything to get my 7 yr old 22kg dog to take drontal tablets for worms! What is the best
iquid wormer please , many thanks wendy

  • VioVet Staff

Panacur will cover roundworms and some species of tapeworm, but not the most common species of tapeworm. It is the most suitable liquid wormer alternative though. Your 22kg dog will need 22mls of the product per worming dose.
From experience I do recommend trying to crush normal worming tablets, like our own brand TermaWorm, into food or a treat as this is the only way to ensure tapeworm coverage. Panacur Solution is a very good wormer but is more suited to smaller dogs/puppies as the liquid can be quite messy to give in large doses.

Work on lungworm?

Noriko Brewster

  • VioVet customer since 2012
  • From: , United Kingdom

this work on lungworm?

  • VioVet Staff

Panacur is licensed to treat some forms of lungworm but not the most common species of lungworm that affects dogs in the UK. If you wish to prevent against adult lungworm causing problems in your dog then I advise using a product containing Moxidectin or Milbeycin monthly instead. These are all prescription only medications.

Tapeworm in dogs


Is Panacur effective against tapeworm in dogs? If not, what would you recommend?

  • VioVet Staff

Panacur will not kill most species of tapeworm. It is recommended to use a tapewormer alongside the product. Our own brand TermaWorm will cover roundworms and tapeworms and is a good over the counter wormer.

It is worth noting that no over the counter (non prescription) wormers will cover lungworm effectively.
