Texas has launched a high-profile legal battle against the makers of Tylenol, arguing that the popular painkiller was deceptively marketed to pregnant women despite claims it may be linked to a higher risk of autism in children. The lawsuit has triggered fresh questions about medical messaging, pharmaceutical accountability and the spread of controversial claims around common medicines.Regulators, doctors and parents are watching closely. The case could influence how over-the-counter drugs are labelled and advertised in the United States.
The big picture
Tylenol, known generically as acetaminophen, is one of the most widely used pain and fever medications in the world. For decades, healthcare professionals have recommended it as the safest option for pregnant women when treating discomfort, fever or headaches.Texas Attorney General Ken Paxton argues that this reputation is misleading. His office claims pharmaceutical companies Johnson & Johnson and Kenvue marketed the drug as safe while allegedly hiding risks.The timing is notable. The lawsuit comes just weeks after former President Donald Trump publicly echoed theories linking paracetamol use during pregnancy to autism, despite mainstream medical bodies rejecting such claims.
What the lawsuit alleges
The Texas lawsuit centres on accusations of consumer deception.Key claims include:
- Tylenol makers “knew or should have known” about possible risks to unborn babies
- The companies allegedly marketed the drug as the only safe pain relief option during pregnancy
- Acetaminophen is claimed to increase the risk of autism and developmental disorders
- The companies financially benefited by promoting safety messaging without proper disclosure
- Texas seeks civil penalties and wants marketing materials reflecting pregnancy safety removed
The legal action invokes the state’s Deceptive Trade Practices Act, which aims to protect consumers from misleading claims.Johnson & Johnson says it no longer owns the consumer health division involved, while Kenvue says the product is safe and that the lawsuit lacks scientific merit.
What does science say
The medical consensus does not support the lawsuit’s central claim.Leading health organisations maintain that acetaminophen is safe during pregnancy when used as directed. Their reasoning includes:
- There is no proven causal link between acetaminophen and autism
- Research that does show possible associations remains inconclusive
- Multiple genetic and environmental factors contribute to autism
- Untreated high fever and severe pain during pregnancy pose documented dangers
Experts warn that scaring pregnant women away from the only recommended medication for fever may lead to worse outcomes. Maternal fever and some pregnancy-related conditions can threaten both mother and baby if left unmanaged.
Why it matters
This case could have wide-reaching effects:1. Pharmaceutical accountability Drug makers may face stricter enforcement on how long-standing products are positioned for pregnancy safety.2. Public health messaging The lawsuit highlights how fast misinformation can spread when political figures amplify unproven claims.3. Access to medication If warnings increase fear, pregnant women may avoid treating conditions that require safe medical intervention.4. Legal precedent A ruling favouring Texas could open the door for similar lawsuits across the US.The tension lies between protecting unborn children and maintaining trust in safest-available care.Courts will examine whether the companies misrepresented Tylenol’s safety profile and whether any scientific concerns were downplayed. More research into paracetamol exposure in pregnancy is already underway, though experts stress that correlation does not prove causation.For now, health authorities still recommend acetaminophen as the safest option to treat pain and fever during pregnancy. The lawsuit highlights the importance of clear, science-backed information as political pressure mounts around maternal health risks.
