WHO:

President Trump

Dr. Jeremy Faust, emergency physician at Brigham and Women's Hospital in Boston

Dr. Caleb Alexander, epidemiology professor at Johns Hopkins Bloomberg School of Public Health

Kenvue, the company that makes Tylenol

Melissa Witt, spokesperson for Kenvue

WHAT:

President Trump warned pregnant women to avoid Tylenol in September 2025, claiming it increases the risk of autism: "Taking Tylenol is not good — I'll say it: It's not good."

Emergency room orders for Tylenol among pregnant patients decreased by 10% following Trump's warning.

There was no change in acetaminophen orders for comparable women who were not pregnant.

The study published in The Lancet analyzed data from electronic health records from over 1,600 hospitals.

Prescriptions for leucovorin, a B vitamin suggested by Trump as an autism treatment, rose sharply and had not fallen back by early December 2025.

WHERE:

Brigham and Women's Hospital, Boston

The study data came from over 1,600 hospitals across the United States.

WHEN:

President Trump's warning was made in September 2025.

The study period ended in early December 2025.

Tylenol consumption reportedly "improved" in December 2025.

WHY:

The decline in Tylenol orders was attributed to President Trump's warning, which had an immediate impact on prescribing behavior.

Dr. Caleb Alexander noted that "words matter" and can change prescriber and patient behavior, especially when coming from a high-profile figure like the president.

HOW:

The study measured changes in Tylenol orders in emergency departments following Trump's announcement, indicating a possible combination of patients declining to take Tylenol and doctors prescribing it less.

President Trump recently warned pregnant women to avoid Tylenol, claiming it increases the risk of autism, which led to a 10% decrease in emergency room orders for the medication among pregnant patients. A study published in The Lancet analyzed data from over 1,600 hospitals and found no change in acetaminophen orders for comparable women who were not pregnant, while prescriptions for leucovorin, a B vitamin suggested by Trump as an autism treatment, rose sharply. Dr. Caleb Alexander emphasized that such statements from a high-profile figure can significantly influence both prescriber and patient behavior.
