Is fenbendazole safe for humans? This is a very common question, and rightfully so. In this article, we will discuss what fenbendazole is and what the limited research is suggesting when it comes to human consumption.


What Is Fenbendazole?

Fenbendazole is a medication used to treat parasites and worms (roundworms, hookworms, whipworms, and some tapeworms) in animals (common brand names are Pancur and Safe-Guard). However, it is also being used by humans in a cancer treatment method known as the Joe Tippens Protocol.

Fenbendazole is part of the benzimidazole family, a class of microtubule-destabilizing agents. Other benzimidazoles, such as albendazole, parbendazole, mebendazole, and flubendazole, have already shown promising results in human studies. Although research on fenbendazole’s potential cancer-fighting properties is limited, one study suggests that fenbendazole has “been safely used as an anti-parasitic for various animal species and could be repurposed for treating human malignancies.

Another study highlights that “repurposing veterinary drugs that show promising results for human use can significantly reduce the time and costs required to develop new drugs.”





Is Fenbendazole Safe for Humans?

While little research has been done on the effects of fenbendazole and human consumption, studies have shown that the medication is typically tolerated well by humans, and thus far, has not reported any major side effects. While we can’t state that fenbendazole is safe for humans, the research appears promising.

According to a 2018 study, fenbendazole (methyl N-(6-phenylsulfanyl-1H-benzimidazol-2-yl) carbamate) is a broad-spectrum benzimidazole anthelmintic approved for use in various animal species. Repurposing veterinary drugs that show promising results for human applications can significantly reduce the time and cost needed to develop new treatments. Fenbendazole is known for its high safety margin and is well-tolerated by most species, exhibiting very low toxicity in experimental animals.

Another study examined the potential side effects of fenbendazole in humans. “Based on limited human data, it appears that doses up to 500 mg per person did not result in adverse effects,” the study states. “Moreover, single doses up to 2,000 mg per person were reported to cause no adverse effects.”




What Is the Joe Tippens Protocol?

The Joe Tippens Protocol was developed by a man who had been diagnosed with small-cell lung cancer. Despite undergoing treatment, his cancer spread to his neck, right lung, stomach, liver, bladder, pancreas, and tailbone, and doctors gave him only three months to live. Refusing to give up, Joe turned to an unconventional approach.

He had heard reports of a scientist at Merck Animal Health who had cured her stage four brain cancer using a canine medication after researching its effects on mice. Inspired by her success, Joe decided to try the same approach. He began taking fenbendazole and later added curcumin and CBD oil, thus creating the Joe Tippens Protocol.
