Panacur Granules Your Trusted Companion for Adult Dog Deworming and Heartworm Prevention!

Address the well-being of your beloved furry companion with Panacur Granules, a reliable solution tailored for adult dogs' deworming and heartworm prevention needs. Specially crafted to combat intestinal parasites, including hookworms, these granules are your go-to choice for maintaining your dog's optimal health.

How Panacur Works:

Panacur Granules boast a potent formulation containing fenbendazole, a broad-spectrum anthelmintic that effectively targets and eliminates various intestinal parasites. Panacur, whose active ingredient is fenbendazole, belongs to the benzimidazole class of anthelmintic drugs. Fenbendazole is effective against many gastrointestinal parasites, making it a versatile and powerful solution for dog deworming.

Inhibition of Microtubule Formation:

Fenbendazole interferes with the microtubule structure in the cells of the parasites. Microtubules are essential cytoskeleton components, providing structural support and playing a crucial role in cell division. By disrupting microtubule formation, fenbendazole inhibits the parasites' ability to divide and multiply.

Disruption of Cellular Metabolism:

Fenbendazole disrupts the energy metabolism of the parasites. It inhibits the uptake of glucose, a vital energy source, leading to a depletion of energy within the parasites' cells. This disruption in cellular metabolism weakens and eventually kills the parasites.

Broad-Spectrum Activity:

Panacur's efficacy extends to various nematodes (roundworms), cestodes (tapeworms), and other gastrointestinal parasites commonly found in dogs. It is effective against Toxocara, Toxascaris, Ancylostoma, Trichuris, Giardia, and more.

Panacur Granules are typically administered orally and are absorbed from the gastrointestinal tract. Once absorbed, fenbendazole is distributed throughout the body, reaching sufficient concentrations to target and eliminate parasites in different organs and tissues.

After absorption, fenbendazole is excreted, and as it passes through the liver, it undergoes biotransformation into metabolites. These metabolites possess anthelmintic activity and are responsible for eliminating parasites from the body. The elimination process involves both adult parasites and larval stages.

While fenbendazole is primarily known for its efficacy against intestinal parasites, it also exhibits some activity against certain stages of heartworms (Dirofilaria immitis).

Comprehensive Dog Deworming:

Panacur Granules provide dependable protection against a spectrum of intestinal worms, ensuring a thorough and effective deworming process. Panacur Granules acts as a powerful defense if your canine friend is at risk due to exposure to fleas or other parasites. These granules protect your dog from discomfort and abdominal pain by preventing intestinal parasites from laying eggs and disrupting their life cycle.

Heartworm Prevention:

Panacur Granules go beyond traditional dog dewormers by doubling as a heartworm preventative. Including fenbendazole helps safeguard your adult dogs from the potential dangers associated with heartworms. These insidious parasites can impact blood vessels and lead to severe health issues. Incorporating Panacur Granules into your heartworm prevention strategy ensures your loyal friend stays healthy and content.

Choose Panacur Granules for a comprehensive, reliable, and effective approach to adult dog deworming and heartworm prevention. Your dog's well-being is our priority!

Excellent for deworming

It works, period. It's not cheap and I find the price on here a little high so do price compare. Be cautious of overdosage. I do not believe you can overdose safely by 10x as written above on this site, especially with puppies! Follow directions, normally Panacur is given 3 days in a row to be effective. Be cautious handling the product and scrub your hands after. If you can glove, you're best off doing so. There are other products you can use in leui of Panacur, search the web and speak to your vet. This normally requires a script, it doesn't appear to which makes life easier with some vets.
