This document does not constitute a medical or dietary prescription, diagnosis, individual therapeutic guidance or a substitute for consultation with a legally qualified health professional.
The use of ivermectin for oncology purposes constitutes off-label use (outside the approved label). Fenbendazole has no registration for human use with ANVISA and is classified as a veterinary drug in Brazil.
Any therapeutic decision, including starting, continuing or interrupting any protocol described in this document, must be made exclusively under the supervision of a physician or qualified health professional, based on individualized clinical assessment, complementary tests and duly documented informed consent.
The authors and developers of this application assume no responsibility for decisions made based on the generated content.
Sources and method
- Only sources with responsible editorial review are admitted: articles indexed in PubMed/MEDLINE with a PMID, clinical trial registrations (NCT), manufacturer package inserts and labels, and publications of regulatory agencies (ANVISA, DCB, FDA, EMA).
- Every clinical number displayed carries its provenance next to it, on screen and in the document. Where there is no source, that is declared: no dose is estimated or inferred.
- The spelling adopted in English is "fenbendazole", the International Nonproprietary Name. In Portuguese the document uses "fembendazol", with an M, as in the Brazilian Common Denomination (DCB 3833) and on the labels sold in Brazil.
- There is no completed phase III trial of ivermectin in cancer, and there is no human trial of fenbendazole in cancer. The 2025 series of 3 cases of self-medication with fenbendazole (PMID 40605964) was retracted in January 2026 and does not serve as support.
Privacy
- No patient data is stored. Name, weight and age exist only in the memory of the request that generates the PDF and come out only inside the document.
- The patient's name never goes into the file name, server logs or on-screen notifications.
- The access account keeps only the name, email and phone of the buyer.
