A 74-year-old Colorado woman, Mary Doran, died from "ivermectin toxicity" after taking a veterinary-grade version of the drug, prompting health experts to issue renewed warnings about the dangers of using ivermectin not prescribed for humans. This incident marks the second death in Colorado linked to ivermectin misuse since 2020, highlighting the risks associated with the veterinary formulations that are more potent than those intended for human use. Health officials urge caution as many individuals sought ivermectin as a treatment during the COVID-19 pandemic despite its ineffectiveness against the virus.
