ATC Vet Code: QP52 AC 13
Fenbendazole is an anthelmintic belonging to the benzimidazole carbamates group. It acts by interfering in the energy metabolism of the nematode. The anthelmintic efficacy is based on inhibition of the polymerisation of tubulin to microtubuli. The anthelmintic affects both adult and immature stages of gastro-intestinal and respiratory nematodes.
Fenbendazole is only partly absorbed from the intestine and reaches maximum plasma concentration in dogs 6 - 24 hours after oral administration. In cats the mean maximum serum concentration of fenbendazole was reached about 4 hours after treatment. Administration of fenbendazole in food did significantly increase its bioavailability compared to the administration on an empty stomach.
Fenbendazole is metabolised mainly by enzymes of the cytochrome P -450 system in the liver. The major oxidative metabolite is fenbendazole sulfoxide which is further metabolised to fenbendazole sulfone.
Fenbendazole and its metabolites are distributed throughout the body but highest concentrations are found in the liver.
The elimination half-life from plasma is about 15 hours after oral administration.
Fenbendazole and its metabolites are predominantly excreted via the faeces.

Below are some recent questions we've received regarding Panacur Wormer Granules for Dogs & Cats, including answers from our team.
Tina
Hi. I have a 2.5kg adult cat with suspected guardia, can you please advise on dosage. I also want to treat my 2 X 4.5kg cats and again would like to know dosage for each of the 3 days. Thank you
Hi there,
For your 2.5kg cat you would need to give one 1g sachet on 3 consecutive days.
For the 4.5kg cats they would each need one 1.8g sachet on 3 consecutive days.
I hope this helps.
Casper.
So, if I'm understanding the Description correctly. To treat a dog weighing 35, or 40 KGS for lungworm I'd need to give one red, 4.5 g sachet a day for 7 days? My GSD weighs about 40 KGS, & I might treat him as a precaution...The Panacur Oral Suspension for Dogs & Cats. To treat for lungworm how much would I need to give a 40 KGS dog for seven days? Thank you. :) :).
I would not actually recommend using Panacur at all to treat lungworm. Although Panacur is effective against a certain type of lungworm, Oslerus (or Filaroides ) osleri, we are not very concerned about this worm in dogs. The lungworm we are concerned about is Angiostrongylus Vasorum which Panacur is not effective against. I would suggest Advocate or Milbemax to treat this lungworm.
Suzanne Williams
I have an 8 year old Springer Spaniel who weighs 19kgs how much do i give and how often
Hi Suzanne,
Here is the dosing guide:
Routine Worming For Adult Cats & Dogs - One Single Dose
Sachets can be combined for dosing dogs over 10kg.
e.g for a 35kg dog:
We would advise worming monthly, but at the very least, every 3 months.
Hope this helps.
Pat Higham
Hello there , my vet has just prescribed a7 day course of Panacur granules for ? Lung town infection in my 2 year old spaniel , and says he will need monthly dose of Panacur to prevent it .as this is practise gold standard . However I note from previous answers that it isn't licensed for this , so I am confused . I obviously want to do best for my dog . Regards Pat Higham
Hi Pat,
Panacur is licensed for the treatment of a specific species of lungworm called Oserlus osleri (also known as Filaroides) so if this is the lungworm your dog is infected with, it will be a safe an effective treatment. Panacur is not licensed or able to prevent an infection, it can only treat an existing infection. If your vet advises regular use to prevent your dog from accumulating a large number of O.osleri lungworm that could cause another problem in the future, then I would follow their advice. Each monthly course would remove any of this type of lungworm he had picked up since the last treatment.
The more dangerous type of lungworm is called Angistrongylus vasorum (picked up from eating infected slugs/snails and potentially from their slime) and this is not killed by Panacur - your vet would need to prescribe a prescription-only product such as Advocate which would give month-long protection against this type of lungworm.
I hope this has been helpful.

How and when to give to a pregnant dog
If you want to have completely worm-free puppies, you need to give a dose every day from day 40 of the pregnancy to 2 days after whelping. This can be done by adding the granules to her food. If you accept that some worms are normal and not a huge concern, then you can worm the bitch once during late pregnancy, then again every time you worm the puppies (ideally at 2 weeks, 5 weeks, 8 weeks and 12 weeks of age).
Full dosing details for everything are on the website. Scroll down and click on Dosage and Administration.
Jacki
My dog weighs 40kgs. What's the dose of Panacur Granules to treat Giardia??
For the treatment of Giardia spp. infections in dogs, administer 50mg fenbendazole per 1kg (2.2lb) bodyweight daily for 3 consecutive days.
This would be achieved by giving two of the 4.5g sachets daily for 3 days.
Iris
Hi, I have an eight yrs old spayed lab weighing 39.5 kg who is on metacalm for her arthritic joints. I've been advised by my vet to give her a 7 day treatment for lungworm as she is lethargic and has an intermittent cough. All blood tests, x rays and scans were clear, and this treatment to r 'eliminate' lungworm as a possible cause. I'm not sure how much to give? f
Your vet should advise you on dose rate and period of treatment. If you are unsure about how things are going with diagnosis or treatment then it is best to ask your vet if you can go for a second opinion. There is nothing wrong with seeking a fresh look at things.
Helen
I have an 8 week old chichuhuaha/Yorkie she was last wormed on Monday (today's Saturday)when is it safe to worm her again?i also have a 3 1/2 year old Yorkie what's safe to give him also exactly how much and how often do I worm each of them? Thanks
Panacur is extremely safe and it would probably be safe to worm every day, though completely unnecessary. The usual advice is to worm puppies every month until 6 or 7 months of age, then reduce this to once every 3 months. If you use Panacur, a dose for a puppy is normally given spread over 3 days. Adult dogs are usually given the dose all in one go.The amount to give depends on the weight of the puppy. This is explained in the tables towards the bottom of the website listing. If you scroll down past the listing for the types of Panacur to the heading "Description" and then click on the heading Dosage and administration you will find a full explanation of how much to give according to the age and weight of your dogs.
Magdalena Bienek
hi there i have a staffordshire bull terrier who has been a little coughy over the past couple of days nothing major that is making me panic i also seem to have a lot of slugs present in my backgarden this summer and im just wondering if its safe to treat my dog as a precaution more than anything else i am due to worm him anyways so would just wondered if it would do him any harm to do the 7 day course thanks
This is an very safe wormer and the chances of you doing any harm with a 7 day course at the correct dose are extremely remote. It might perhaps be of benefit to your dog, but it is difficult to say. However the type of lungworm which dogs get from eating slugs is not the one which Panacur is licensed to treat. For that lungworm you need to use a prescription wormer. You would have to ask your own vet about the possible merits of using that.
Eve
My cat is pregnant, due in ten days. When working out dose for panacur liquid do I use her normal weight or pregnant weight?
This is a good question. You should in fact use her pregnant weight for this, the drug is well distributed through the body but is very safe for the unborn kittens.
