AUSTIN — In Mueller, where stroller traffic shares the Aldrich Street sidewalks with pharmacy counters and pediatric waiting rooms, a statewide fight over acetaminophen has landed close to home. Expectant parents here are asking the same question as doctors and pharmacists across Texas: what should we do now?

What the lawsuit says

Texas Attorney General Ken Paxton has sued Johnson & Johnson and its consumer spinoff Kenvue, alleging the companies failed to warn pregnant consumers about potential neurodevelopmental risks tied to acetaminophen, the active ingredient in Tylenol. The case, brought under state consumer-protection laws, argues the companies concealed safety information and misled Texans, according to Reuters.

Paxton framed the effort in stark terms, saying that “by holding Big Pharma accountable for poisoning our people, we will help Make America Healthy Again,” according to Reuters. Kenvue and Johnson & Johnson deny there is a causal link between acetaminophen use in pregnancy and autism, saying independent science supports the medicine’s safety when used as directed, Reuters reported.

The lawsuit runs alongside a separate track of federal cases in which families allege prenatal exposure to acetaminophen caused developmental harm. Many of those claims have been consolidated in multidistrict litigation. Unlike those personal-injury suits, the state’s case targets alleged deceptive practices and does not require proving individual causation in the same way, according to Reuters.

The regulatory signal

Even as the legal fight grows, federal regulators have taken a cautious step. The Food and Drug Administration has initiated a process to update labels on acetaminophen products to reflect evidence of a possible association between use during pregnancy and conditions such as autism and ADHD, according to FDA. The agency characterized the move as an information update, not a directive to avoid the drug, with an emphasis on shared decision-making between patients and clinicians.

That nuance matters in Mueller, where OB practices that serve the neighborhood and nearby East Austin often recommend acetaminophen to treat fever and pain because other options are riskier in pregnancy. Local obstetric providers say the label-change process will likely prompt more conversations at prenatal visits about dose, duration and alternatives, a perspective echoed by several Mueller-area pharmacists who say they expect more questions at the counter.

What the science shows — and doesn’t

The evidence linking acetaminophen use in pregnancy to autism or ADHD is mixed. A large analysis published in JAMA found that while some statistical models showed marginally increased risks, analyses that compared matched full siblings — a design that better controls for shared family factors — found no association for autism, ADHD or intellectual disability, according to JAMA Network.

Other studies have reported signals that merit attention. A prospective cohort study tied prenatal acetaminophen exposure to higher attention-problem scores at age 3, according to PubMed. Research highlighted by UW Medicine has linked maternal use to a higher risk of ADHD. But reviewers caution that many of these findings come from observational designs subject to confounding — for example, the underlying illnesses that prompt a pregnant person to take acetaminophen might themselves influence child outcomes.

That is why many clinicians continue to view acetaminophen as the least risky over-the-counter option in pregnancy. The American College of Obstetricians and Gynecologists reaffirmed that position in September, noting the harms of untreated fever and severe pain. “The conditions people use acetaminophen to treat during pregnancy are far more dangerous than any theoretical risks and can create severe morbidity and mortality for the pregnant person and the fetus,” ACOG President Dr. Steven J. Fleischman said in a statement, according to ACOG. The American Academy of Emergency Medicine has issued similar guidance urging judicious use while acknowledging ongoing research, according to AAEM.

For families trying to interpret headlines, context helps. Autism diagnoses have risen in the United States over the past two decades, a trend many experts attribute in part to broader screening and expanded criteria, not a single new cause, according to Harvard Health. The American Council on Science and Health has summarized the debate by emphasizing that current evidence does not establish causation and recommending careful, medically guided use, according to the American Council on Science and Health.

What this means for Mueller parents

In a neighborhood with one of Austin’s highest concentrations of young families, the practical questions are immediate. A Mueller obstetrician described, in paraphrase, a week of back-to-back counseling visits: people who took acetaminophen for a fever want to know what it might mean for their baby; those in the second trimester ask what to use for a migraine; others bring in social media posts and ask if they should throw out their medicine cabinet.

Local pediatricians who care for Mueller families say, in paraphrase, that they expect more questions at well-baby visits and more requests for developmental screening referrals. Mueller-area pharmacists describe, in paraphrase, updating shelf tags and training technicians to flag pregnancy-related questions to the pharmacist.

Clinicians and public-health guidance point to a few practical steps:

  • Talk first. If you are pregnant or planning to be, discuss pain and fever plans with your clinician in advance, providers say, a recommendation consistent with ACOG and AAEM positions.
  • Use the lowest effective dose for the shortest time needed, a standard echoed by national medical groups and consistent with the label-update direction described by FDA.
  • Avoid mixing products that may duplicate acetaminophen. Pharmacists note that many cold and flu remedies contain it — a point Harvard clinicians also stress in consumer guidance, according to Harvard Health.

Ashley Keller, an attorney involved in related litigation, said the public deserves more disclosure. “We are not sure, and therefore we should sound the alarm,” he said in an interview. Companies counter that the evidence does not prove harm. “Independent, sound science clearly shows that taking acetaminophen does not cause autism,” Kenvue has said, according to Reuters.

The road ahead in Austin

For now, the day-to-day in Mueller remains focused on careful conversations rather than abrupt changes. The FDA’s process could lead to revised language on drug facts labels that patients see at neighborhood pharmacies, according to FDA. Medical organizations continue to advise that acetaminophen remains the preferred over-the-counter choice in pregnancy when clinically indicated, according to ACOG and AAEM. And researchers will keep testing questions about timing, dose and confounding — with sibling-controlled designs serving as a key tool, as shown by JAMA Network — even as other studies continue to report associations that deserve study, as noted by PubMed and UW Medicine.

In the meantime, the advice heard most often in Mueller exam rooms is straightforward: don’t panic; bring your questions; and make a plan tailored to your pregnancy, your symptoms and your risks. The legal fight may be statewide, but the decisions remain intensely local — one conversation at a time.
