A sudden drop in Kenvue Inc.’s stock by 10% has shaken investors, consumers, and the broader healthcare industry. The sharp decline came after news reports suggested that Robert F. Kennedy Jr., now a high-ranking government health official, is preparing to release a report linking acetaminophen.
Kenvue, a major pharmaceutical and consumer health products company spun off from Johnson & Johnson, holds the iconic Tylenol brand in its portfolio. With Tylenol long considered one of the safest over-the-counter medications for pain and fever during pregnancy, any suggestion of risk—no matter how preliminary—can trigger widespread concern.
This article takes a comprehensive look into the reasons behind the stock slump, the scientific debates surrounding Tylenol and autism, public health implications, and what lies ahead for Kenvue.

Why Kenvue Stock Dropped
The stock slump was triggered not by a published scientific paper, lawsuit, or government warning, but by a report in development—allegedly being spearheaded by RFK Jr.—that will propose a connection between prenatal acetaminophen use and autism in children.
Investor Reaction
Markets react swiftly to news that threatens public trust in a brand, especially a healthcare brand. Tylenol is a cornerstone product for Kenvue, generating billions annually in revenue. A hit to Tylenol’s reputation directly affects the company’s profitability and future growth potential.
Investors anticipate potential outcomes such as:
- Decreased consumer demand
- Negative media coverage
- Class-action lawsuits
- Regulatory reviews
Long-term damage to Kenvue’s brand equity
Hence, the 10% drop in stock price reflects not just the risk of declining sales, but the legal and reputational dangers that may follow.
RFK Jr.’s Report: What’s Known So Far
While the report hasn’t been officially published, inside sources claim it will outline a potential biological pathway between acetaminophen and neurological development, suggesting that use during pregnancy may disrupt fetal brain development, possibly leading to autism.
Key Points Likely in the Report
- A review of epidemiological studies showing a correlation between prenatal acetaminophen use and autism or ADHD
- Focus on oxidative stress and hormonal disruption as potential biological mechanisms
- Possible dietary factors (e.g., folate deficiency) interacting with acetaminophen to increase risk
- Recommendations for reduced use of Tylenol during pregnancy and alternatives for pain management
- Suggestions for further clinical research
It is important to note that correlation is not causation, and the scientific community remains divided on the issue.
Kenvue’s Official Response
Kenvue responded quickly to the news, issuing a public statement reaffirming that acetaminophen has been used safely for decades, including during pregnancy. The company emphasized:
- Tylenol has been reviewed and approved by regulatory bodies worldwide.
- There is no conclusive evidence linking Tylenol to autism.
- Consumers should consult with their healthcare providers and not make decisions based on speculation.
The company is also expected to increase its public relations and scientific communications efforts to rebuild investor and consumer confidence.
Understanding the Tylenol-Autism Debate
The Origins of the Controversy
Concerns about a link between acetaminophen and autism started gaining attention over the past decade, mostly from:
- Observational studies suggesting a slight increase in autism risk in children whose mothers used acetaminophen frequently during pregnancy.
- Research exploring chemical mechanisms that could interfere with fetal brain development.
- Anecdotal reports from parents and some healthcare professionals.
However, these findings have been inconsistent, and no randomized controlled trial has definitively established causation.
Scientific Research: What Does It Say?
Studies Suggesting a Possible Link
Meta-analyses of observational studies have reported a weak association between acetaminophen use in pregnancy and neurodevelopmental disorders.
Some researchers argue that acetaminophen may cause oxidative stress, altering fetal brain development.
Studies in animal models have shown neurochemical changes following acetaminophen exposure.
Studies Refuting the Link
- Large population-based studies in Scandinavian countries and the U.S. found no significant increase in autism rates when controlling for other risk factors.
- The FDA, CDC, and WHO have not issued any warnings or restrictions on Tylenol use in pregnancy.
- Many experts argue that confounding variables (like maternal illness, genetics, or environmental exposure) may explain the association.
Expert Consensus
Most medical bodies still maintain that acetaminophen is safe for short-term, occasional use during pregnancy. However, they also recommend that all medications during pregnancy be used cautiously and only when necessary.
Public Health Implications
Pregnant Women and Confusion
Expectant mothers may now face increased anxiety and uncertainty over what medications are safe. Tylenol is often the first-line treatment for fever and pain during pregnancy, and its potential removal from that toolkit could cause real concern.
This may lead to:
- Reduced adherence to pain management plans
- Increased use of untested or less safe alternatives
- Higher rates of untreated pain or fever, which can also harm fetal development
Trust in Public Health Institutions
With RFK Jr.’s history of challenging scientific consensus, his position in health policy leadership adds complexity. Some experts fear that his promotion of fringe theories could undermine public trust in established guidelines.
If this report gains traction without robust peer review, it could set a precedent for science-by-press-release, sidelining rigorous scientific discourse.
Legal and Financial Risks for Kenvue
The legal landscape surrounding Tylenol and autism is not new. In recent years, multiple lawsuits have been filed against manufacturers, alleging:
- Failure to warn pregnant women of potential autism risks
- Misleading marketing that encouraged liberal use
Most of these cases have been dismissed, largely because:
- The evidence presented was not considered scientifically reliable
- Regulatory agencies have not found acetaminophen to be unsafe
However, a new government report—even if speculative—may breathe new life into old lawsuits or inspire new class-action cases, potentially costing Kenvue billions in litigation expenses and settlements.
The Road Ahead for Kenvue
Short-Term Strategies
Kenvue will likely focus on:
- Damage control via PR campaigns
- Engaging scientists and doctors to publicly support Tylenol’s safety
- Monitoring legal exposure and preparing for potential lawsuits
- Investor reassurance through earnings calls and shareholder letters
Long-Term Implications
- May accelerate investment in alternative pain relief products
- Could impact over-the-counter (OTC) drug regulation
- Potential push for warning labels or packaging changes for Tylenol
- Pressure to fund or participate in new clinical trials to affirm safety
Frequently Asked Question
