Texas Attorney General Ken Paxton is suing Johnson and Johnson, accusing the pharmaceutical company of failing to warn consumers about the risk of taking Tylenol while pregnant.

This lawsuit, the first of its kind from a state government, comes a month after President Donald Trump and U.S. Secretary of Health and Human Services Robert F. Kennedy, Jr. announced updated guidance discouraging pregnant women from taking acetaminophen, citing it as a possible cause of autism. The announcement set off a wave of controversy in the health care community, and confusion among pregnant women unsure how they should manage fever and pain during pregnancy.
