What Is Fenbendazole 150 Mg?

Fenbendazole 150 Mg is a prescription drug for the treatment of parasitic infection in both adults and kids. It can treat various types of worms that affect the respiratory system, intestine, and even protozoan infections.

• Active ingredient: Fenbendazole

• Drug class: Benzimidazole anthelmintic

• Primary use: Treats intestinal parasites in animals

Considering the overall aspects, Fenbendazole 150 is a highly effective treatment for various types of parasitic infections, with minimal side effects, suitable for both adults and children.

How Does Fenbendazole 150 Mg Work?

Fenbendazole targets the parasites and binds to the microtubules of the worms. It then works by stopping the worm from multiplying by cutting short its nutritional intake. Thus, it destroys the spread of the parasites.

It then works on the infected area and removes the symptoms (itching, swelling, rashes) and eventually, when all the worms are destroyed, it will remove all the remnants through stool. At that time, you can face intestinal pain or diarrhoea.

• Disrupts the parasite’s ability to absorb glucose

• Causes energy depletion and death of worms

• Effective against multiple stages of parasites (eggs, larvae, adults)
