Fenbendazole 1000 mg comes in tablet, suspension, and granule forms designed for animals such as dogs, cats, horses, cattle, and poultry.

Usage of Fenbendazole 1000 mg
Veterinarians prescribe Fenbendazole 1000 mg for:
- Treatment of gastrointestinal worms

Working of Fenbendazole
Fenbendazole functions by disrupting the energy production of parasites. It blocks the formation of microtubules within their cells, preventing them from absorbing glucose. Without energy, the parasites become immobilized and eventually die.
This mechanism targets:
- Nematodes
- Certain types of tapeworms
- Some protozoa
Fenbendazole is favored due to its high safety margin, meaning it is typically well-tolerated when administered correctly.
