Postman Delivers Justice
Postman Law attorneys are leading litigation against Johnson & Johnson Consumer Inc., now known as Kenvue, the manufacturer of Tylenol, as well as retailers who sell their own store-branded acetaminophen (such as Target, Walmart, and CVS) for failing to properly warn that prenatal exposure to acetaminophen could lead to ASD and ADHD. Numerous studies have shown that consuming acetaminophen while pregnant increases a child’s risk of developing neurodevelopmental disorders like ASD and ADHD. The defendants knew of the risks and nevertheless continued to manufacture and sell these products to pregnant women without an adequate warning. Postman Law is fighting to deliver justice to our clients and to all those injured by the defendants.
Strong Science Linking Prenatal Acetaminophen Exposure to ASD and ADHD
Increasing experimental and epidemiological research shows that prenatal exposure to acetaminophen alters fetal development, significantly raising the risk of neurodevelopmental disorders.
Based on the overwhelming scientific evidence, in September 2021 over ninety scientists signed a consensus statement published in Nature Reviews Endocrinology, calling for precautionary action over the use of acetaminophen during pregnancy. Nature Reviews Endocrinology is a leading, highly regarded, peer-reviewed medical journal.

Acetaminophen (APAP) is a common ingredient found in many over-the-counter (OTC) pain relievers, prescriptions, and also cold medicines. It is commonly known as a pain reliever and fever reducer.

The Acetaminophen — ASD/ADHD multi-district litigation will likely be eventually resolved through a negotiated settlement. Because this litigation began in mid 2022, the compensation that plaintiffs will receive is currently unknown and difficult to forecast. However, as soon as we are able to predict the compensation that victims will receive, we will share an update here.
We unfortunately cannot predict with any certainty how long it will take for cases to resolve, as litigation is unpredictable. There is no way to know just yet. But we will keep this page updated and also ensure that our clients are notified with any key developments.
We will pursue your claim on a contingency fee basis, meaning that there is no upfront payment, fees, or expenses until we win your case and recover money on your behalf.
