Verified Purchase

By Evelyn Green on 9 May 2026

I got this as my dog was due for his wormer treatment. I like that it is in a bottle and I can use the syringe as he is quite a nervous dog. Good value, prompt delivery and goes a long wayZ

Q & A

Below are some recent questions we've received regarding Panacur Liquid Cat & Dog Wormer, including answers from our team.

Suitable for adult cats with giardia?

Xena

Hello, the liquid seems to be suitable for kittens, puppies and adult dogs with giardia, but doesn't seem to be suitable for adult cats, is that correct?

Is it only the granules that can help an adult cat with giardia?
And is there any good alternative?

  • VioVet Staff

Yes, Panacur Liquid can be suitable for treating Giardia in adult cats, provided you use the right dose and follow vet guidance (especially on duration). It’s a commonly used treatment option.

How long can you keep product after opening

Mel

How long after opening bottle can you keep it before it goes off

  • VioVet Staff
  • The scientifically supported shelf life after opening Panacur Liquid is 3 months, assuming it’s stored properly (cool, dry environment, tightly sealed, away from direct light).

  • However, due to labeling and regulatory compliance, many retailers advise discarding the bottle after 28 days once opened—despite it remaining chemically stable longer.

To stay on the safe side, check the label’s instructions—if it states ā€œuse within 28 days,ā€ follow that. If no such guidance is given, you can rely on the 3-month stability window while still keeping an eye on any changes in appearance or odor.

And, best way to administer.

For the control of lungworm in dogs administer 1 ml per 2 kg body weight for 7 consecutive days.A repeat course of treatment may be required in some cases. 28kg dog would need 14ml per day for 7 days.

Dosage for puppy

Jenny

My maltipoo is 3 months old and the breeders advice was to give a worming treatment every 3 months alternating between Drontal and panacur.
Will this cover everything?

  • VioVet Staff

The most common parasite to infect puppies is roundworm, Panacur and Drontal Puppy Suspension will treat just that. Puppies can also become infected via the mother's milk so please ensurer to treat the mother also. You do not need to alternate between the two as they both target the same species of parasite and there are no records of resistance. Please refer to the dosage instructions for treatment intervals. From 6 months of age, you will need to include tapeworm treatment into your plan. If you have any further questions, please don't hesitate to contact one of our qualified SQPs here who will be happy to help.

Taste and smell

john gray

Is thia product odourless and tasteless

  • VioVet Staff

No Panacur is not tasteless, however, it does not have a specific 'taste' or 'smell' but you may need to mix it in some food while feeding.
