A viral post claiming a 66-year-old woman's stage 4 cancer disappeared after taking a 'dewormer' has spread widely across social media and alternative health blogs. But experts agree that scientific data does not exist about whether fenbendazole is safe and effective for people, and the claims can give people false hope and potentially cause harm.
The account describes the woman reportedly taking fenbendazole or ivermectin alongside or after chemotherapy, with the narrative claiming the antiparasitic drug eliminated her tumour, where conventional treatment allegedly failed. Such social media stories tap into the desperation of patients and caregivers seeking affordable miracle cures.
