Ivermectin is a deworming drug intended for use in animals, including horses and cows.

(MORGANTOWN, WV) Though researchers have been studying the animal deworming drug ivermectin for decades, there is no evidence that it’s a safe or effective way to treat cancer in people.

However, a June 2026 study put the topic back in the spotlight. After being downloaded more than 85,000 times before its official publication, the study gained traction on social media – particularly X – and within alternative health communities, where it was shared widely to bolster broader claims about repurposing antiparasitic drugs as cancer treatments. While traditional news outlets were covering renewed public interest in ivermectin for cancer following the COVID-19 pandemic, much of the conversation surrounding this particular new study unfolded outside of mainstream media coverage.
