A benzimidazole anthelmintic drug, fenbendazole, is effective against parasites in dogs and pigs. In addition to its antitumor effects and inhibition of microtubule-associated tubulin polymerization, the agent is also known to be safe and tolerable in humans. Pembrolizumab monotherapy was started on an 80-year-old female fenbendazole powder with advanced nonsmall cell lung cancer (NSCLC). It was 9 months later that the patient suffered severe liver damage. She and her family were interviewed and revealed that she had been taking fenbendazole for a month on the basis of social media reports suggesting its efficacy against cancer.
What is Fenbendazole Powder?
Fenbendazole is absorbed from the small intestine into the bloodstream, distributed throughout the body, metabolized, and eliminated via biliary and urinary excretion. The compound does not bind covalently to plasma proteins. Routes of Exposure: Ingestion of oral tablets and suspension by mouth. Fenbendazole has been identified as a possible human carcinogen (IARC Group 2B) based on sufficient evidence in experimental animals for its ability to induce tumors of the liver and lungs.
The chemical is metabolized in the body, forming various hydroxylated metabolites that are excreted in urine and feces. Elimination half-life: 3 days.

How Long Does It Take to Work for Dogs?
My dog is a medium size dog and has been taking the pill for about 6 months. He’s very active and has lots of energy. He can jump and run for hours. I also have him on a diet consisting of raw meat, chicken, duck, salmon, liver, and other organ meats. His weight has gone up from 17 pounds to 23 pounds. When I first started giving him the pill, I noticed he wasn’t as active; he was always tired.
I figured that maybe it was because he was too skinny. After giving him the pill for about 3 months, I started noticing that he was getting more active again. About 6 months ago, I started noticing his hair was falling out in clumps. I took him to the vet, and she said it was just normal shedding but told me to keep an eye on it. I’m really concerned about his health because of all these symptoms and his hair falling out in clumps. He’s only 11 years old, and I worry about him getting sick. I feel like the pill is making him weak.
