Medical Disclaimer

The information on this website is for general education only. It is not medical advice, diagnosis, or treatment.

No doctor–patient relationship

Using this website, contacting us by email, or reading our articles does not create a doctor–patient relationship. The authors are researchers and writers, not clinicians. Our content cannot account for your diagnosis, stage, medications, allergies, liver or kidney function, or any of the dozens of factors a treating physician weighs.

We deliberately publish no doses

Fenbendazole is approved as a veterinary dewormer. It has never been tested in a completed, controlled human cancer trial, so no safe and effective human dose for cancer exists — which is exactly why this site does not publish dosing, schedules, or “how to take it” instructions for any drug or supplement. Websites that do publish such instructions are guessing, and documented adverse events show that guessing carries real risk.

Evidence changes, and so may this site

Medicine is not static. What we describe as the current state of evidence reflects the sources cited on each page, checked on the date shown. New trials, warnings, or studies may change the picture. We update core pages regularly and note material corrections openly.

If you are in crisis or have symptoms

If you have chest pain, trouble breathing, uncontrolled vomiting, yellowing of the skin or eyes, unusual bleeding or bruising, fever during chemotherapy, or any sudden severe symptom, contact your care team immediately or call your local emergency number. Do not use this website — or any website — as a substitute for emergency care.

External links

We link to regulatory agencies, journals, trial registries, and Joe Tippens’s own website as primary sources. A link is a citation, not an endorsement, and we are not responsible for the content of other websites.
