Ivermectin Isn’t a Proven Cure. So Why Do So Many People Believe It Is?

Once promoted as a COVID-19 treatment, ivermectin — along with the veterinary drug fenbendazole — is now being touted online as a cancer cure, driven by viral anecdotes and early research that scientists say falls far short of proof…

“This has worked miracles for me,” said Kevin Town, a 55-year-old YouTube creator from Ashville, New York, as he held up two white tubes in a video posted January 4, 2026.

The tubes contained ivermectin and fenbendazole paste — products marketed as horse dewormers that Town says he bought at a local Tractor Supply store. But to Town, these were more than medications for livestock: They were an affordable and effective alternative to the conventional cancer treatments that, over the span of a year, had drained his savings and left him feeling sicker.

According to his video posts, Town was diagnosed with kidney cancer in September 2024. In November of that year, he underwent a nephrectomy, a surgery to remove his left kidney. Nine months later, Town learned his cancer had progressed and spread to his bladder and prostate. He underwent another painful procedure to remove the tumors, but his doctors told him it wasn’t enough.

“They said, ‘In order to save your life, we have to remove your bladder and your prostate at the same time’,” Town recalled in his video. He said the surgery would leave him using a urostomy bag for the rest of his life.

“I told them I didn’t want that done,” he explained. 

Facing the cost of ongoing appointments and prescriptions, Town decided to try an alternative solution: He bought ivermectin and fenbendazole, treatments he said he had discovered through online posts, including from some medical professionals. He said he alternated between the two, taking each daily for a week, then switching to the other.

In his January 4th video (which has since racked up more than 21,000 views), Town says that after four months of taking the $17 veterinary drugs, he felt healthy again. 

Town, who declined MedShadow’s request for a direct interview, has continued to post updates on his health on YouTube. 

On April 10, Town told his viewers he had returned to his primary care doctor for the first time in seven months. He said his doctor was “absolutely amazed” at how good he looked and that he had not experienced any cancer symptoms since the previous year.

In a video uploaded on May 15, the last one Town posted before this article’s publication, he holds up the results of a CT scan, blood work, and a urinalysis, and tells viewers his doctor had found “no sign of cancer at all.”
