• Kenvue stock fell as much as 10% due to claims linking Tylenol to autism.
• Shares rebounded by 6% after the initial drop, due to lack of new scientific evidence.
• Health officials have not found a causal link between Tylenol and autism, stressing concerns over potential maternal health risks.

Kenvue's stock experienced significant volatility recently, initially plunging nearly 10% as reports surfaced regarding the White House's plans to link Tylenol use during pregnancy to autism. This development has raised serious concerns, particularly as Health and Human Services Secretary Robert F. Kennedy Jr. emphasized the potential public health implications of such claims. Notably, Kenvue, the maker of Tylenol, has publicly disagreed with these assertions, insisting that scientific evidence indicates no causal relationship between acetaminophen use and autism, according to Business Insider.

Following this sharp decline, Kenvue shares rebounded approximately 6% in premarket trading, as analysts clarified the situation. Analysts pointed out that Trump's controversial remarks, which included advice for pregnant women to avoid Tylenol altogether, were based on outdated studies rather than recent scientific findings. They noted that despite Trump's statements, no substantial new evidence supports a link between Tylenol and autism. Analysts from Citi highlighted the possibility of limited judicial risk but acknowledged that negative public perception could influence product consumption, according to Reuters and India Times.

Furthermore, the FDA announced it would update labeling on Tylenol products to reflect ongoing discussions on the use of acetaminophen during pregnancy, although they stressed that no causal links have been definitively established. A spokesperson from the World Health Organization mentioned that available evidence remains inconsistent, emphasizing that vaccines should not be questioned. Kenvue's management expressed concern over suggestions that could lead to dangerous choices for pregnant women, potentially pushing them towards untreated fevers or less safe alternatives, as reported by Reuters and India Times.
