What Does the Research Actually Say About Fenbendazole and Human Health?

In recent months, I noticed more and more discussions about fenbendazole and its possible health benefits, particularly regarding cancer. But I would like to see if there are any scientific studies other than social media posts.

Based on my findings, fenbendazole is an antiparasitic drug used for veterinary purposes to treat some parasitic worm infections. In laboratory settings, it was tested for its effects on cancer cells, which, however, does not mean it can be taken by humans.

Also, I would like to know how the promising results of the lab tests should be translated into the reality of human trials. What criteria are used by scientists for determining the safety and effectiveness of a drug for people?

It is also worth mentioning that fenbendazole was never approved for human use in the US, and there are some reports about the risk of liver damage after self-administration of this substance.

I believe that when doing any research, one should rely on the medical literature rather than stories of random people or social media posts. Is there any medical study of this drug that explains what is currently known and what.
