What is Fenbendazole 150 mg?
Fenbendazole is a broad-spectrum anthelmintic medication used to treat parasitic infections in animals. It belongs to the benzimidazole group of drugs and works by disrupting the energy metabolism of parasites, eventually killing them.
The 150 mg dosage is one of the more common strengths, especially in tablet or granule form, and is often prescribed for dogs and other household pets.
How Does Fenbendazole 150 mg Work?
In simple terms, Fenbendazole starves parasites to death.
It inhibits the parasite’s ability to absorb glucose, leading to energy depletion and cell death. Interestingly, this same mechanism has gained attention in the medical research community for its potential impact on cancer cells, but more on that later.
Common Uses of Fenbendazole 150 mg
Veterinary Applications

Human Off-Label Interest
In recent years, some people have turned to Fenbendazole for non-FDA-approved uses, especially in the realm of cancer support. This has sparked curiosity (and controversy) about whether an animal dewormer could actually help people.

Fenbendazole and Cancer: The Joe Tippens Protocol
The Joe Tippens story is what launched Fenbendazole into mainstream curiosity. Diagnosed with terminal lung cancer, Joe began self-administering Fenbendazole alongside supplements like vitamin E, CBD oil, and curcumin.
He later claimed to be cancer-free, and although this is anecdotal and not medically proven, it prompted further interest and even some early scientific studies.
⚠️ Important Note: This protocol is not approved by health authorities. Always consult your doctor before considering off-label treatments.
