Fenbendazole dosage for humans

Case Rep Oncol 1 September ; 14 2 : —

When fenbendazole became difficult to obtain on the market, even the human anthelmintic albendazole was sold out. Anti-cancer effects of fenbendazole, albendazole, and mebendazole have been known against cancer cell lines in vitro for a long time. Clinical trial with fenbendazole is impossible, because it is not permitted for human use due to toxicities. Even though the Korean Ministry of Food and Drug Safety warned that this claim was unfounded and that side effects of such drugs could damage patients, the outbreak of the anthelmintics is still ongoing. A conspiracy theory argues that pharmaceutical companies are interfering with clinical trials of anthelmintics in cancer patients. However, it is not true because several clinical trials have been done with support from companies clinicaltrials.

Fenbendazole is a benzimidazole-class anthelmintic that is used for the control of immature and adult stages of internal parasites, such as nematodes and trematodes, in domestic food-animal species. It is not approved by the United States Food and Drug Administration for treating pheasants despite Syngamus trachea being one of the most prevalent nematodes that parasitize pheasants. Because it is a highly effective treatment, e. Therefore, we conducted a risk assessment to evaluate the potential repeat-dose and reproductive, teratogenic, and carcinogenic human risks that may be associated with the consumption of tissues from pheasants that were previously treated with fenbendazole. We conducted a quantitative risk assessment applying both deterministic and stochastic approaches using different fenbendazole sulfone residue limits tolerance, maximum residue limits, and analytical limit of detection established in different poultry species by the Food and Drug Administration, the European Medicines Agency, and other regulatory agencies in Japan, Turkey, and New Zealand. Our results show that fenbendazole poses minimal risk to humans when administered to pheasants in an extra-label manner, and a comparison of different fenbendazole sulfone residue limits can help assess how conservative the withdrawal interval should be after extra-label drug use. Also, the United States Department of Agriculture census states that 7,, pheasants were sold live in 1.

Take the required amount of fenbendazole after a high fat meal daily for 6 days, skip on the seventh day and repeat weekly. Fenbendazole mg. Take three times a week, once a day after a high fat meal. Then take no fenbendazole for four days. Repeat the cycle every week. Repeat for 10 weeks. Then Stop for 10 weeks. Repeat the cycle. One study published in by Dr.

Resistance to Thiabendazole, Fenbendazole and levamisole in Haemonchus and Trichostrongylus species in sheep on a Kenyan farm. This study aimed to estimate the risk associated with human consumption of tissues obtained from fenbendazole-treated pheasants. Related Articles. This finding is reinforced just looking at the interquartile range of the log consumption that is needed to have observable effects Figure 2 , demonstrating that when the risk for presenting effects is low i. Oncology ;61 1 — Sci Rep ;8 1 Drug library screen reveals benzimidazole derivatives as selective cytotoxic agents for KRAS-mutant lung cancer. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Cytotoxic anticancer agents which act on microtubules include vinca alkaloids vinblastine, vincristine, vinorelbine, and vindesine and taxanes paclitaxel and docetaxel. A For the treatment and control of large strongyles Strongylus edentatus, S. Depending on the severity of the parasitic infection, morbidity and mortality can be quite high in pheasants, among other game birds 4. A sensitivity analysis for the LOD distribution and repeat-dose NOAEL was performed to evaluate the impact that changes in input values have on the number of pheasant tissues with fenbendazole sulfone residues a person has to consume a day to have observed adverse effects.

Antiparasitic drugs such as fenbendazole have caught the attention of researchers studying pancreatic cancer. In early studies, they have shown promise in inhibiting the growth and spread of cancer cells.

In the United Kingdom, this drug is being used and approved in several game bird species at a dose of 12 ppm orally. Not for use in beef calves less than 2 months of age, dairy calves , and veal calves. The most prevalent nematode in pheasants is Syngamus trachea 5. Another study reported that methiazole and fenbendazole suppressed RAS-related signaling pathway expression in lung cancer cells with a KRAS mutation [ 16 ]. As fenbendazole is a veterinary medication, as indicated by the EMA 22 , this product is limited to being prescribed by veterinarians. She had no known history of drug or food allergies. Moreover, the highest value of pheasant tissue consumption a person has to eat daily to have observed adverse effects, 2,, Clinical trial with fenbendazole is impossible, because it is not permitted for human use due to toxicities. Centers for Disease Control and Prevention. Therefore, it is very useful to obtain a range of values that take into account all possible scenarios to be able to evaluate whether or not the consumption of pheasant tissue with fenbendazole sulfone residues is safe.
