Description

Prinovox is a broad spectrum parasite treatment for dogs, cats and ferrets. It provides protection against lungworm, heartworm, intestinal roundworms, fleas, lice and mites. Prinovox is easily given by being applied as a "spot-on" treatment to the skin at the back of the neck (where the animal cannot easily lick it off).

Very effective
Verified Purchase

By Margaret Mundy on 8 February 2026

I’d always used Frontline Spot-On with my previous dogs, but I realised it had stopped working when to my horror, I found Finlay with fleas! I had to spray the whole house (what a nightmare!), and the vet prescribed Prinovox. Thankfully it worked very quickly and there has been no recurrence of the problem since we started using this.

Q & A

Below are some recent questions we've received regarding Prinovox, including answers from our team.

Lungworm

Catherine

Does Prinovox protect against lungworm?

  • VioVet Staff

Yes, Prinovox is a medication used to treat lungworm infections in dogs, specifically those caused by Angiostrongylus vasorum (a type of lungworm that can affect dogs). Prinovox contains a combination of moxidectin and praziquantel, which work together to treat and prevent a variety of parasitic infections, including:

  • Lungworm (Angiostrongylus vasorum)

  • Heartworms

  • Intestinal worms

  • Tapeworms

  • Ear mites (in some cases)

If you suspect that your dog may have lungworms or if your vet recommends Prinovox, it's essential to follow the prescribed dosage and treatment regimen to effectively eliminate the infection. Always consult with your veterinarian for the appropriate treatment plan based on your dog's condition.

Ticks and treatment or only prevention of lungworm

Leanne Cordner

  • VioVet customer since 2017
  • From: West Midlands, United Kingdom

does this kill ticks too?
also does it only prevent lungworm etc?
not treat it?
what is needed to kill lungworm?

  • VioVet Staff

Prinovox will not cover against ticks. It prevents against lungworm infestation but also fleas, mites and lice. If you would like further advice on what flea/worming to use then please get in touch with our customer services.
