Fenbendazole Lab

Fenbendazole is a broad-spectrum, benzimidazole carbamate anthelmintic that has been used in humans and veterinary medicine for over six decades. It is a member of the benzimidazole family and works by binding to tubulin and inhibiting its polymerization.

Three daily i.p. injections of fenbendazole were ineffective in suppressing tumor growth or radiosensitivity in EMT6 mice (Figure 3). This drug does not interact with the microtubule stabilizing agents paclitaxel and peloruside A.


Fenbendazole is an animal anthelmintic used to treat parasitic infections of various species. It is also being studied for its potential anticancer effects in laboratory animals. However, no peer-reviewed studies have found evidence that this class of medications can cure cancer in humans.

Febendazole has been shown to be toxic to EMT6 tumor cells in culture and in mice. It has been found to enhance the cytotoxic effects of hypoxia-selective nitroheterocyclic chemotherapeutic agents and radiation.

Inhibition of tubulin polymerization by fenbendazole may block cell-cycle progression and induce mitotic catastrophe. We therefore investigated the effect of fenbendazole on cyclin B1 levels in A549 cell cultures that had been synchronized by serum starvation. Treatment of these cells with varying concentrations of fenbendazole for 2 or 24 h resulted in different survival rates, which were measured by colony formation assay. Survival data were analyzed and reported as yield-corrected surviving fractions. Treatment with fenbendazole at the highest dose tested did not significantly affect survivals in monolayer cultures.

Side Effects

Fenbendazole is a broad-spectrum, anthelmintic drug that also has been studied as a possible cancer treatment. However, it is currently listed as a veterinary drug and Health Canada does not endorse the use of this medication for cancer treatment.

The drug works by binding to b-tubulins of nematode cells and interfering in their dimerization with a-tubulins, which inhibits the polymerization of tubulin into microtubules, an important part of the cytoskeleton that gives shape and support to cells. This inhibits protein synthesis and halts cell division. It is a powerful antiparasitic that has similar effects as cytotoxic anticancer drugs.

The drug is commonly used in extra-label drug applications to treat intestinal helminths, including pinworms (Trichuris) and Giardia. It is also effective in dogs against gastrointestinal nematodes and lungworms, such as Taenia solium. The drug has been shown to be effective in the control of other parasites as well, such as roundworms and hookworms.


Fenbendazole is part of a group of drugs called benzimidazole carbamate anthelmintics, which have been in use as broad-spectrum anthelmintic agents for more than six decades. Other members of the benzimidazole family include metronidazole, albendazole and mebendazole.

Fenben lab granules should be stored in a tightly sealed container at room temperature, away from sunlight. It’s important that you follow storage recommendations as specified by the veterinarian who prescribes the medication for your pet.

This medication is not a good choice for pets that are in the process of growing or molting feathers. It may not work or could cause harm to them. This is because fenbendazole needs to be given for a period of time in order to kill the parasites, and if your pet is growing new feathers or molting they are not going through this period. If your pet does have feathers growing out, you should discuss this with the veterinarian before giving him fenbendazole.


Fenbendazole belongs to a broad group of anti-parasitic drugs called the benzimidazole carbamate anthelmintics. It has been used for nearly six decades as an effective wormer in both human and veterinary medicine. Its effectiveness is based on its ability to bind to mammalian ss-tubulin, destabilizing it and inhibiting its function. This results in the cell’s destruction.

Typically, fenbendazole is given for three days on and four days off. If you are taking any medications or treatments that increase liver enzymes, take fenbendazole with caution.
