Fenbendazole 222mg Capsules For Humans

fenbendazole 222mg capsules for humans is well-tolerated at a single oral dose of up to 222 mg/kg per day. It is effective against parasites of the intestinal tract including roundworms (Toxocara canis, Toxocara vittata), hookworms, whipworms and certain tapeworms such as Strongyles and Strongyloides.

Fenbendazole does not alter the dose-response curves for radiation or docetaxel, nor does it interact with these agents in vitro. It also does not interfere with the ability of radiation to inhibit tumor growth in vivo.


Fenbendazole, marketed as Panacur, is a broad-spectrum benzimidazole antihelmintic. It kills whipworms, lungworms, the tapeworm genus Taenia (but is ineffective against Dipylidium caninum, a common dog tapeworm), pinworms, and hydatid worms. It also has antiproliferative effects in leukemia, multiple myeloma, and melanoma cells.

In three experiments using EMT6 tumors, fenbendazole administered by diet or as three daily i.p. injections did not alter tumor growth or the ability of radiation to decrease tumor volume. Fenbendazole, however, did significantly increase the time to doubling of tumor volume when it was given as a single dose prior to radiation exposure.

Some patients, including cancer survivors, have adopted the Joe Tippens protocol, which involves taking 222 mg of fenbendazole for three days consecutively and four days off. However, it is recommended to work with a health care professional before starting the protocol to avoid interactions between supplements and other medications. For example, long-term fenbendazole use can suppress white blood cells and bone marrow, and it may interfere with some chemotherapy agents.

Side Effects

The basic fenbendazole dosage is 222 mg per day. Joe Tippens, who popularized the use of fenbendazole for cancer, suggests that patients take it for three consecutive days and then four days off.

Febendazole is a broad-spectrum benzimidazole that has been used in humans for over 40 years to treat a variety of parasitic diseases. It also limits cancer cell fueling with sugar by blocking GLUT transporters and inhibiting the enzyme hexokinase.

During the first few weeks of fenbendazole therapy, some patients may experience side effects such as stomach discomfort and nausea. However, these symptoms can be a sign that the medication is working and that pathogens are being killed inside the body. During this time, it is important to drink plenty of water and sleep often. After a few weeks, these symptoms should go away. If they do not, patients should consult a doctor or nurse. Then, patients can increase their fenbendazole dose by 222 mg increments until they reach 2000 mg daily.


Fenbendazole is a widely used benzimidazole with a broad spectrum anthelmintic effect, especially against the gastrointestinal parasites giardiasis, roundworms, hookworms, whipworms, Taenia genus tapeworms and pinworms. It is also approved for use in livestock including sheep, cattle, goats, and swine. It can be given orally in granules and liquid suspensions. It is a veterinary medicine and should only be administered under the guidance of a veterinarian.

It has been shown to be well tolerated by humans after oral administration and is typically taken three days on, four days off. Occasionally, drooling and/or vomiting may occur with the initial dosage.

Research has shown that combining fenbendazole with certain vitamins can enhance the effectiveness of the treatment. One example is an experiment in which a human lymphoma xenografted into SCID mice was inhibited by the addition of fenbendazole and supplementation with vitamins A, D, E, K, and B (see figure below). The dietary supplement that was used in this study was a sterilizable diet that was not autoclaved, and therefore contained higher-than-normal concentrations of some vitamins.


Fenbendazole is a moderate-acting medication and should be well-tolerated at regular doses. At high doses (which are not typically used in veterinary medicine), the drug may interfere with the normal function of liver and kidney cells.

If your dog or cat experiences any adverse effects, contact a veterinarian immediately. Fecal examinations should be done to ensure that all parasites have been killed by the medication.

The Joe Tippens protocol has been gaining popularity in the cancer community after a man named Joe claimed that his lung cancer was cured by taking fenbendazole, also known as Panacur C, three days on and four off. The anti-parasitic drug was designed to kill parasites, but it is now being touted as a possible cancer treatment.

Fenbendazole comes as granules and as liquid suspension and is given by mouth. Liquid forms should be measured carefully and given with food to reduce gastrointestinal upset. Always use the exact dose and duration prescribed by a veterinarian.
