Robert F. Kennedy Jr. is set to reveal a report from the HHS that purportedly links the use of Tylenol during pregnancy to autism, raising alarms in the pharmaceutical community. Following reports of this connection, Kenvue, the maker of Tylenol, experienced a significant drop in stock prices, plummeting by 10%. While many reports suggest a potential association, experts, including Dr. Gupta, cautioned that such claims do not establish a direct cause-and-effect relationship. The developing story underscores a growing scrutiny of acetaminophen, especially regarding its use by expectant mothers, amid calls for more research into its safety and potential neurodevelopmental risks.
