Once a suspect COVID treatment, now a cure for everything
Excerpt – The idea that ivermectin could be a cancer-fighting agent does have some modest basis in reality: Preliminary studies have suggested that antiparasitic medications might inhibit tumor growth, and at least one ongoing clinical trial is evaluating ivermectin’s role as an adjunct to cancer treatment. That study has enrolled only nine patients, however, and the results so far show that just one patient’s tumor actually shrank, according to a recent scientific abstract. But these meager grounds for hope now support a towering pile of expectations.
[..] a gaggle of dubious doctors has worked to bolster the credibility of deworming drugs within alternative medicine and anti-vaccine circles. Their underlying pitch has become familiar in the past few years: Health experts can’t be trusted; the pharmaceutical industry is suppressing cheap cures; and patients deserve the liberty to choose their own medical interventions. For the rest of the medical establishment, the worldview this entails is straining doctor-patient relationships. [Utah radiation oncologist who studies medical misinformation Skyler] Johnson told me that many of his patients are now skeptical of his advice, if not openly combative. One cancer patient accused Johnson of bias when he failed to recommend ivermectin. The drug is so cheap and effective, this patient had concluded, that Johnson would be out of a job if everyone knew about it. (Johnson told me that he offers patients “the best possible treatment, no matter the financial incentive.”) Ivermectin has become a big business in its own right. Online pharmacies and wellness shops are cashing in on the deworming craze, with one offering parasite cleanses for $200 a month. Meanwhile, fringe doctors can charge patients who have cancer and other diseases thousands of dollars to prescribe such treatments.
[..] Before it turned into a conservative cure-all, ivermectin was legitimately a wonder drug for the poorest people on Earth. Since its discovery in 1973, it has become a leading weapon in the fight against horrific infections such as river blindness and elephantiasis. Yet now that substantial success seems to have given birth to a self-destructive fantasy.
A decade ago, the co-discoverers of ivermectin—William Campbell and Satoshi Ōmura—were awarded a Nobel Prize in recognition of their contribution to reducing human suffering. In his formal lecture to the Academy, Campbell offered some reflections on the simple science that gave rise to the treatment, and to its wide array of applications. But his speech contained a warning, too, that any medicine that works so broadly and so well runs the risk of being handed out too often. The more benefits that such a drug provides, he told the audience in Stockholm, “the more we must guard against the hazards of indiscriminate use.”
