Acetaminophen Lawyer in Chicago

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. In Tylenol, acetaminophen is the only active ingredient. The way acetaminophen relieves pain is by blocking pain signals within the central nervous system.

If you took acetaminophen while pregnant and your child was subsequently diagnosed with autism spectrum disorder (ASD) or attention deficit hyperactivity disorder (ADHD), you may qualify for legal action.

In order to support your claim, we may also request additional information, such as how frequently you took acetaminophen, why did you take acetaminophen, what dosage you took, etc. We may also ask for information related to your child’s subsequent diagnosis of autism or ADHD.

If you believe your child’s autism or ADHD was caused by prenatal exposure to acetaminophen, we encourage you to start by immediately contacting an attorney that specializes in product liability. At Postman Law, we have the expertise to review your case, determine if you are eligible to file a claim, and answer any question you may have about the process.

Please start a claim and one of our attorneys will contact you as soon as possible.

Postman Law handles your confidential information with care and limits access to your medical records. Our firm will only reveal your information as we deem necessary for your case or if you specifically authorize Postman Law to use your information for another purpose. There are a few other limited reasons we might need to disclose medical information, such as if a court orders us to release client records.

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.

Current Status: In late 2023, the federal judge overseeing the Tylenol (acetaminophen) lawsuits excluded plaintiffs’ expert witnesses on general causation, which resulted in dismissal of the cases in federal court.

While the appeal is pending, lawsuits continue in state courts across the country. At the same time, new government statements, including September 2025 guidance from the White House and Health and Human Services, highlight the risks of prenatal acetaminophen use, strengthening the fight for families. Keller Postman remains at the forefront of these efforts, pursuing justice nationwide.
