Vetina Canworm (Fenbendazole) — Broad-Spectrum Dewormer That Also Treats Giardia

Vetina Canworm Deworming Suspension contains Fenbendazole 10% w/v (100 mg per ml) — a broad-spectrum benzimidazole anthelmintic that eliminates the widest range of intestinal and systemic parasites of any dewormer in its class. Unlike most standard dewormers, Canworm also effectively treats Giardia — a protozoal parasite responsible for chronic watery diarrhoea in dogs and cats that is resistant to many other dewormers. It is safe to use in dogs, cats, puppies, kittens, pregnant and lactating animals, rabbits, and birds.

Ingredients:

Fenbendazole: The active ingredient, Fenbendazole, is a broad-spectrum anthelmintic that targets and eliminates various types of intestinal worms, including roundworms, hookworms, whipworms, and certain tapeworms.

What does Canworm treat?

• Giardia (Giardia duodenalis) — protozoal infection causing chronic diarrhoea, poor coat and weight loss

• Roundworms (Toxocara canis / T. cati) — most common intestinal parasite in puppies and kittens

• Hookworms (Ancylostoma caninum) — blood-feeding worms causing anaemia and weight loss

• Whipworms (Trichuris vulpis) — difficult to treat; cause chronic large-bowel diarrhoea

• Tapeworms (Taenia species) — note: NOT effective against Dipylidium caninum (flea tapeworm)

• Lungworms, lungflukes, hairworms, pinworms — extended parasite coverage

How Fenbendazole works?

Fenbendazole blocks the production of tubulin — a structural protein worms need to form their cell skeleton. Without tubulin, parasites cannot maintain their body integrity, fail to absorb glucose, and die. It is effective against both adult worms and larval stages, providing more complete clearance than many single-stage dewormers.

FAQs

Does Canworm (Fenbendazole) treat Giardia in dogs and cats?

Yes. Vetina Canworm is one of the few dewormers available in India that is effective against Giardia — a protozoal intestinal parasite that causes chronic, watery diarrhoea and poor coat condition in dogs and cats. Most standard dewormers (including those containing only praziquantel or pyrantel) are NOT effective against Giardia. Fenbendazole, Canworm's active ingredient, disrupts the cellular structure of Giardia parasites, starving and eliminating them. Treatment is typically given for 3–5 consecutive days for Giardia infection.

What worms does Canworm Fenbendazole Suspension treat?

 Canworm treats a broad range of parasites: Giardia (protozoal), roundworms (Toxocara canis), hookworms (Ancylostoma caninum), whipworms (Trichuris vulpis), tapeworms (Taenia species), lungworms, hairworms, and pinworms. Important note: Canworm is NOT effective against Dipylidium caninum — the tapeworm spread by flea bites. If your dog has flea-related tapeworms, a praziquantel-based dewormer is required.

I can see worms in my dog's stool after giving Canworm — is this normal?

Yes, this is completely normal and is actually a sign that the medication is working. Fenbendazole kills parasites inside the intestinal tract, and your dog's body expels them through normal bowel movement. You may see dead worms or worm segments in stools for several days after treatment. This typically stops within 3–7 days of completing the dose. If you still see live, moving worms more than a week after treatment, or if symptoms persist, consult your vet about a second treatment course.
