Medical group reaffirms Tylenol safety in pregnancy after federal warnings
Medical experts reaffirm Tylenol safety for pregnant women despite Trump administration warnings linking the common pain reliever to autism.

COLUMBUS, OHIO β A national medical organization released new guidance this week reaffirming that acetaminophen, commonly known as Tylenol, remains the safest pain reliever for pregnant women, directly contradicting federal warnings issued by the Trump administration last year.
The Society for Maternal-Fetal Medicine published clinical guidance stating that acetaminophen should be the “first-line” defense against pain and fever during pregnancy. This follows months of medical uncertainty after President Trump made unsupported claims linking the medication to autism in children.
Federal guidance prompted medical review
The Trump administration issued a notice to physicians last year cautioning against acetaminophen use during pregnancy, the primary pain reliever recommended for expecting mothers. These federal statements prompted the Society for Maternal-Fetal Medicine to review its 2017 guidance that found acetaminophen safe for pregnant women.
After conducting the review, the national professional association for maternal-fetal medicine specialists, clinicians, and scientists continues to recommend acetaminophen as the “first-line medication” to treat pain and fever during pregnancy.
Scientific evidence examined
The medical organization acknowledged that some studies have suggested potential links between maternal acetaminophen use and developmental outcomes in children. However, the new guidance emphasizes significant limitations in existing research.
“Although some studies have reported associations between maternal acetaminophen use and adverse neurodevelopmental outcomes in offspring, methodological limitations preclude conclusions about causality, and the biological mechanism for such an effect remains unestablished,” according to the statement published by the Society for Maternal-Fetal Medicine.
The organization’s position maintains that current scientific evidence does not support the federal administration’s warnings against acetaminophen use during pregnancy.
Ongoing policy tensions
The medical guidance comes amid broader changes in federal health policy under Health and Human Services Secretary Robert F. Kennedy Jr., who has directed the U.S. Food and Drug Administration to shift its research into autism toward potential environmental causes.
The conflict between federal warnings and medical professional recommendations has created uncertainty for pregnant women and their healthcare providers. The Society for Maternal-Fetal Medicine’s reaffirmation of acetaminophen safety provides clear guidance for clinicians treating pregnant patients.
The organization’s stance reflects the position of mainstream medical professionals who continue to view acetaminophen as the safest available option for pain and fever management during pregnancy, despite ongoing federal scrutiny of the medication.
