Kenvue's Rollercoaster: How Tylenol Maker's Shares Defied Trump's Autism Claims

A financial storm brewed for Kenvue, the consumer health giant behind Tylenol, when former President Donald Trump ignited a firestorm with unsubstantiated claims linking the popular pain reliever to autism. But in a dramatic turn, the company's shares, initially shaken, staged a remarkable rebound, showcasing market resilience amidst a torrent of political rhetoric and scientific debate.

The catalyst for the market's initial jitters came from Trump's social media platform, where he controversially suggested that acetaminophen, the active ingredient in Tylenol, could be a cause of autism in children.

He went further, advocating for a ban on 'Tylenol and similar drugs' during pregnancy, citing a 'strong link' to developmental disorders.

Despite these sensational claims, the scientific and medical communities stand firm: there is no definitive causal link established between acetaminophen use during pregnancy and autism or ADHD.

Leading authorities such as the U.S. Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), and the American College of Obstetricians and Gynecologists (ACOG) maintain that when used as directed, acetaminophen remains a safe option for pregnant individuals needing pain relief.

Indeed, a comprehensive study published in JAMA Pediatrics in 2024 further reinforced this position, finding no association between maternal acetaminophen use and the incidence of autism or ADHD in offspring, directly countering the narrative propagated by Trump.

However, Trump's comments aren't entirely isolated from ongoing legal battles.

Kenvue and its former parent company, Johnson & Johnson, are currently entangled in multi-district litigation, facing hundreds of lawsuits alleging that prenatal acetaminophen exposure leads to autism and ADHD. While a federal judge initially dismissed these claims in 2022, citing a lack of scientific basis, a federal appeals court surprisingly revived the lawsuits in 2023, paving the way for these complex cases to potentially move forward.

Kenvue, which spun off from Johnson & Johnson in 2023, boasts a formidable portfolio of household names beyond Tylenol, including Motrin, Listerine, Band-Aid, and Neutrogena.

As an independent entity, it's a prominent player in the consumer health sector, making the impact of such widespread public claims particularly significant for its brand integrity and market valuation.

Ultimately, the stock market appeared to process the information, weigh the scientific evidence against the political rhetoric, and recover.

After an initial dip, Kenvue's shares clawed back most of their losses, reflecting investors' continued confidence in the company's fundamentals and, perhaps, a collective dismissal of unsubstantiated claims lacking scientific backing. The episode underscores the volatile interplay between public discourse, scientific consensus, and market dynamics in the digital age.
