Utilised as a remedy for parasitic worm infections in dogs, fenbendazole is an anthelmintic drug that has been in circulation since the early 1970s. (Source)
However, in more recent years there have been numerous published and peer reviewed papers with case reports proving that fenbendazole is also very effective in the treatment of some aggressive cancers in humans. This is believed to be because of the following various strong points that distinguish fenbendazole from other cancer fighting treatments:
- There are a significant number of scientific publications that support and substantiate its effective use in treating some aggressive cancers in humans. (Source)
- It has been reported that Fenbendazole alone is an effective treatment for causing the regression of tumors in patients with diffuse large B-cell lymphoma, metastatic cancer, renal cell carcinoma, and bladder cancer. Fenbendazole has shown promise as a potential treatment for many forms of cancer. (Source1),(Source2)
- Fenbendazole has very few side effects and is very safe for humans to use.
- It is available over-the-counter in many countries.
- It is extremely inexpensive to produce.
Moreover, in our article How fenbendazole works? we reported that the fenbendazole anticancer action is very similar to the plant alkaloids group of chemotherapies to which the anticancer therapy Taxol belongs. Furthermore, due to the unique way it works and its exceptional safety profile, fenbendazole’s toxicity levels are far lower than those seen in conventional chemotherapies.
Through many observations and findings, it has become apparent (with the emergence of certain patterns) that the origin of some cancers may be related to and triggered by viruses, parasites, and the like.
In fact, it’s possible that this is the case in many more instances than we are aware of, especially if the cancer cells find themselves in “fertile ground”, represented by compromised immunity combined with specific genetic predilections.
Therefore, we seriously consider the use of anti-parasitic, anti-worm, anti-lactate and other drugs as part of a comprehensive cancer treatment approach that can also include the use of conventional cancer therapies.
Fenbendazole for humans
Fenbendazole is not a drug that is habitually used in the treatment of humans, like mebendazole. Typically used in cases of animals (including mammals, birds, and fish) with parasites, fenbendazole is known to kill numerous parasitic worms such as whip worm, hookworm, some tape worms, and roundworm.
Found under brand names such as Panacur or Safe-Guard, fenbendazole was first brought to our attention in relation to the treatment of cancer years ago through our own research. However, more recently it has captured our attention again through the renowned story of a man who successfully treated his small cell lung cancer with the anti-worm drug.
Since then, a dedicated website and a Facebook group serve as a platform to chronicle his own experience, as well as the experience of other patients who are experiencing the benefits of using Fenbendazole in treating cancers such as non-small cell lung cancer, melanoma, colorectal cancer, prostate cancer, stage four pancreatic cancer and other types.
These recent reports only go further to help support the existing and mounting scientific evidence that demonstrates the cancer fighting potential linked to numerous drugs in the benzimidazole class of compounds. Due to this, we are of the opinion and belief that, like mebendazole, fenbendazole for humans is displaying a significant cancer fighting potential.
In fact, there are some studies where fenbendazole has proved to be more efficacious than mebendazole. E.g., in one such study fenbendazole was demonstrated to be much more successful than mebendazole and other drugs in fighting Cryptococcus neoformans – an opportunistic fungus which can be found anywhere in the world and may cause Cryptococcus meningitis in some people.

Furthermore, of the many scientific articles that have been published and suggested that Fenbendazole demonstrates cancer fighting properties, this paper, Fenbendazole acts as a moderate microtubule destabilizing agent and causes cancer cell death by modulating multiple cellular pathways, determined that:
- “The results, in conjunction with our earlier data, suggest that Fenbendazole is a new microtubule interfering agent that displays anti-neoplastic activity and may be evaluated as a potential therapeutic agent because of its effect on multiple cellular pathways leading to the effective elimination of cancer cells.”
The authors of this paper concluded that fenbendazole’s cancer fighting mechanisms not only disrupted the proteasomal interference and microtubule function of cancer cells, but also showed an ability to block glucose uptake, inherently starving the cancer cells. Fenbendazole reduced the expression of glucose transporter isoform 4 (GLUT4). Stimulation of glucose uptake in cells through insulin moves GLUT4 through the intracellular vesicles to the plasma membrane, ready to absorb glucose. By disrupting its linear movement through the microtubule with fenbendazole, GLUT4 movements are inhibited, which greatly reduces insulin-stimulated sugar uptake. (Source)
Moreover, as fenbendazole works similarly to colchicine (interacting with a site on tubulin) yet is distinctly different from other vinca alkaloids, it will not compete with them or other chemotherapies. Instead, as is the case with other benzimidazole compounds, fenbendazole will enhance the anti-cancer effects of other cancer therapies, such as surgery, radiotherapy, sodium dichloroacetate (DCA), berberine etc. (Source)
Adding to this, a recently published scientific paper proposes that fenbendazole (and similar drugs) can potentially reactivate genome p53. Functioning as a tumor suppressor, p53 is known as the Guardian of the Genome. However, its suppression ability can be inhibited in some cancers. (Source)
Furthermore, the Nature paper goes on to cite that fenbendazole was very effective when combined with DCA.
Fenbendazole for humans – is it good fit for human consumption?
Although fenbendazole is ordinarily and originally used for the treatment of parasitic worms in animals, a report available at the European Medicine Agency states, “Fenbendazole seems to be well tolerated in humans after oral exposure (single oral dose up to 2,000 mg/per person: 500 mg/per person for 10 consecutive days)”. (Source)
However, long exposure has not yet been scientifically documented. This most likely is due to the nature of the drug – the parasitic infections are usually eradicated in no longer than 1-2 weeks.
Despite that, many people have taken fenbendazole daily for years as a prophylaxis to prevent cancer recurrence or as an active treatment against their tumors. The treatment appears to be safe and it rarely, if ever, causes any side-effects.

Today, while I was at work, my cousin stole my iPad and trsted to see if it can survive a
25 foot drop, just so she can be a youtube sensation. My apple ipad iis now
destroyed and she hhas 83 views. I know this is completely off
topic but I had to share it with someone!
Is Fenbendazole the same as Phenbendazol? I’m ordering from Fen Lab from Amazon. I want to take it for parasites. How long should I take it for this purpose…at 222mg per day?
Hello, Jan, thank you for a question.
Yes, it is the same compound, only spelling differs in some dialects or counties. For parasite prevention you can count the dosage at our dosage guide. At the section “Fenbendazole For” press “Parasites” and write your weight. Calculator will show how you should use it.
What is the dosage of pure Fenbendezole? I have 222mg capsules. How many do I need to take per day to help.with small cell lung cancer?
Hello, Luise and thank you for this question!
You should start with a dosage that you can calculate according to your weight: https://www.fenbendazole.org/fenbendazole-information/fenbendazole-dosage-guide/
You should begin with a dose that can be calculated based on your weight.
If you believe you are taking too much or too little, we recommend that you monitor your liver enzyme levels (which may be done with a blood test) and only increase the amount if you are in relatively good health. Remember to be cautious and responsible, even if the medication is not very hazardous on your body.
It is safe to take fenben along with immunotherapy for stage 4 liver cancer_
Thank you for your response and God bless
I have stage 3 melanoma skin cancer which is incurable, I am 44 and have Immunotherapy every 4 weeks. I want to start taking fenben but not sure which protocol to follow any help would be greatly appreciated and do I buy the stuff from the Fenben Lab shop?
Is there any reason to start at a lower dose when switching over from the Merck Panacur brand of Fenbendazole to the Fenbendazole sold on the Fenben Lab site? My mom was taking 2000mg Panacur-C and we’re starting her on the Fenbendazole Pure now.
Dear Theresa, thank you for your question. Panacur C 1000 mg = pure fenbendazole 222 mg. 2 grams of Panacur C equates to 444 mg of pure capsulated fenbendazole. If you currently take 444 mg, you will not reduce your dosage.
My husband is 74 and has t liver cancer have gone through chemotherphy, radiation, Immunotherphy and it didn’t touch the tumor in fact it grew in size a month ago they stopped so treatments and we were told nothing more they can do so he is in Hospice to die When we first found out is when he had another heart attack #8 needed bypass but found couldn’t do it because of the cancer he was high risk this was April7,2022
In May 2021, I was diagnosed with stage IV endometrial cancer. After six months of difficult chemotherapy treatment and an additional twelve months of Maintenance chemo, I started taking fenbendazole in March 2022, increasing my dosage up to 2000 mg per day, in addition to some dietary supplements. After consulting with a few doctors, they advised me to slightly adjust my regimen and add a few more nutritional supplements. I also made a conscious effort to cultivate a positive outlook and kept myself surrounded by hope and optimism. Today, I received the best news anyone could hope for – there was no evidence of active disease!!
In June 2022, I was diagnosed with Thymic Carcinoma and I’ve been undergoing chemotherapy for 8 weeks now. Besides chemo, I’ve also been taking fenbendazole, curcumin, vitamin D & K, and CBD oil. My next PET scan is scheduled for October, and hopefully that it will show the tumors are gone or at least reduced somewhat
How can i try this? IM NOT AFRAID OF IT I HAVE DID CHEMO AND RADIATION. RIGHT NOW IM DOING KEYTRUDA EVERY 3 WEEKS. IF THIS IS FOR ME PLEASE LET ME KNOW. THANK YOU SO MUCH. PAULA.
Dear Paula,
thank you for your message. You can seek the advice of a naturopath on how to take fenbendazole. Otherwise, you could carefully read the fenbendazole dosage section, then find some fenbendazole in your local shop or order it directly to your home and start the treatment. If feasible, take CBD and curcumin simultaneously with the regimen.
