Description

Panacur granules contain the popular worming agent Fenbendazole in a convenient granular form for adding to food. Virtually tasteless, they can be mixed with a small treat, or just into the normal food. Effective against the major roundworm species including Toxocara (which can cause problems if accidentally transmitted to humans). It is effective against the Taenia species of tapeworm but not against Dipylidium caninum or Echinococcus multilocularis. Panacur Granules are mild and kind to pets but lethal to worms!

Below are some recent questions we've received regarding Panacur Wormer Granules for Dogs & Cats, including answers from our team.

Dosage for panacur granules

Jan Thomas

Having trouble following the data sheet recommendations for dosage and how often to treat. I have a dog she weighs 10.4kgs. What dosage should I be giving her and do I give the medication just once or spread out over 3 days?

  • VioVet Staff

Your dog is just over the 10 kg sachet size, so:

  • 4.5 g Sachet (10 kg) + 0.5 g extra granules would be ideal.

  • Since sachets aren’t smaller than 1 g, the practical recommendation is:

    • One 4.5 g red sachet + one 1 g yellow sachet = 5.5 g total (slightly over but safe, as fenbendazole has a wide safety margin).

For routine warming, this can be given once - not for 3 days. 3 days is only required if your dog has worms and requires treatment.

Dosage

Kat

Hi, which one do I need for. 2.7-3kg cat? Thanks

  • VioVet Staff

For a cat that weighs around 2.7-3 kg, the recommended dose of Panacur Granules (22.2% fenbendazole) is:

  • 1.8 g sachet — this covers up to about 4.4 kg bodyweight, so it’s sufficient for a 2.7-3 kg cat. Blue Sachet.

Lungworm

Sam smith

  • VioVet customer since 2016
  • From: , United Kingdom

I'm treating my dog for lungworm using the 7 day treatment at half the dose, will this also treat any other worms at this dose or would I need to do 1 separate treatment at the full dose

  • VioVet Staff

The 7-day lungworm protocol typically uses 25 mg/kg once daily for 7 days.

If you’re halving that dose (so effectively 12.5 mg/kg), it's not considered an effective dose for intestinal worms based on available clinical data.

While fenbendazole is fairly safe and sometimes works at lower doses, the half-dose 7-day course likely won't reliably clear common intestinal worms — you'd typically need at least 50 mg/kg for 3 days (or 25 mg/kg for 7 days) to treat them effectively.

Which one for my dog?

Rebecca

What is the difference between the different colours and what is the correct dosage for a 35kg German shepherd and for how long?

  • VioVet Staff

The dose for a 35kg dog would be (3 x 4.5g Sachet) + (3 x 1g Sachet), administered as one single dose every 3 months.

Cat Dose

BF

I have two cats, one 5.6kg and one 4.3kg. What dosage do I give them please as a routine treatment? One full sachet each or part thereof?

  • VioVet Staff

Your cat weighing 5.6kg will need 1x 1g and 1x 1.8g sachets and your cat weighing 4.3kg will need just 1x 1g sachet every 3 months.
