What Kind of Cancer Does Fenbendazole Cure? All You Need to Know

Cancer is a devastating disease that affects not only humans but also our beloved pets. Dogs, in particular, are susceptible to various types of cancer, and the treatment options can be limited and expensive. However, there is a growing interest in an affordable and readily available drug called fenbendazole that is believed to have cancer-fighting properties. In this article, we’ll explore what fenbendazole is, how it works, and how it may be used to help treat cancer in dogs.

What is Fenbendazole?

Fenbendazole is a broad-spectrum antiparasitic drug commonly used in veterinary medicine to treat and prevent various types of internal parasites, including roundworms, hookworms, whipworms, and tapeworms. It works by disrupting the parasites’ ability to absorb nutrients, eventually leading to their death. Fenbendazole is available in various forms, including tablets, granules, and paste, and is generally considered safe and well-tolerated by most dogs.

What is Fenbendazole Used For?

Apart from its antiparasitic properties, fenbendazole has recently gained attention for its potential anticancer properties. In particular, its ability to inhibit the growth and spread of cancer cells has been studied in various preclinical models, including human cell lines and animal models. Although the exact mechanism of action is still unclear, fenbendazole is believed to work by inducing apoptosis (programmed cell death) in cancer cells, thereby preventing their proliferation and metastasis.

How Does Fenbendazole Work?

Fenbendazole’s anticancer properties have been studied in various types of cancer, including melanoma, glioblastoma, and colorectal cancer. In one study, researchers found that fenbendazole inhibited the growth of melanoma cells by up to 90% in vitro and by 50% in vivo. In another study, fenbendazole was shown to prevent the proliferation of colorectal cancer cells by inducing cell cycle arrest and apoptosis.

Fenbendazole Dosage for Cancer

Although the optimal dosage of fenbendazole for cancer treatment is still unclear, some studies suggest that higher doses than those used for antiparasitic treatment may be necessary. In general, the dosage of fenbendazole for cancer treatment ranges from 50 mg/kg to 200 mg/kg, depending on the type and stage of cancer. However, it’s essential to consult with a veterinarian before using fenbendazole for cancer treatment, as the dosage may vary depending on the individual dog’s health status and response to treatment.

Fenbendazole for Parasites

It’s worth noting that fenbendazole should not be used as a substitute for other cancer treatments, such as chemotherapy or radiation therapy. Rather, it should be considered as a complementary treatment that may help improve the effectiveness of conventional cancer treatments or alleviate some of the side effects associated with them. Moreover, fenbendazole can still be used for its primary purpose, which is to treat and prevent internal parasites in dogs.

Fenbendazole Side Effects

Like all drugs, fenbendazole has potential side effects, although they are generally mild and rare. Some of the reported side effects of fenbendazole include vomiting, diarrhea, lethargy, and loss of appetite. However, these side effects usually subside after a few days of treatment. It’s essential to monitor your dog’s health status closely while on fenbendazole treatment and to report any unusual symptoms to your veterinarian.

Fenbendazole Safety

Fenbendazole is generally considered safe and well-tolerated by most dogs, but it’s still important to follow the recommended dosage and administration guidelines. Fenbendazole should not be used in pregnant or lactating dogs or in dogs with liver or kidney disease without consulting a veterinarian. Moreover, it’s important to avoid using fenbendazole in combination with other drugs without consulting a veterinarian, as it may increase the risk of adverse effects.

Fenbendazole Research

Despite the promising results of fenbendazole in preclinical studies, more research is needed to determine its optimal dosage, safety, and efficacy in dogs with cancer. Some clinical studies are underway to evaluate the use of fenbendazole as a complementary treatment for various types of cancer in dogs. However, until more data is available, fenbendazole should be considered an experimental treatment that requires close monitoring and careful consideration.


In conclusion, fenbendazole is a versatile drug that has shown promise as a complementary treatment for various types of cancer in dogs. While more research is needed to determine its optimal dosage, safety, and efficacy, its affordability and availability make it an attractive option for pet owners looking for alternative cancer treatments. However, it’s important to consult with a veterinarian before using fenbendazole for cancer treatment and to keep in mind that it should not be used as a substitute for other cancer treatments.
