WORMENTEL

WORMENTEL 222 MG

 

What is this medicine?

Wormentel 222 mg contains fenbendazole, a broad-spectrum anthelmintic (anti-worm) medication. It’s primarily used to treat intestinal parasitic infections in both animals (dogs, cats, livestock) and sometimes humans, effective against roundworms, hookworms, whipworms, tapeworms, and certain protozoa. It works by inhibiting β‑tubulin in parasites—disrupting glucose uptake, causing immobilization and death.
