The official White House X account unveiled a provocative — and seemingly effective — social media tactic this week directed at Tylenol.

Trump warned against giving babies Tylenol during the briefing, and a letter from the FDA to physicians -- though focused on acetaminophen use during pregnancy -- referenced the developing livers of young children and their potentially limited ability to metabolize the drug.

Former President Barack Obama said the Trump administration engaged in “violence against the truth” with its announcements this week linking autism and Tylenol.

In February 2017, it advised another social media user — who had praised Tylenol "for being pregnancy safe" — to seek a clinician’s advice: "Thanks for the shout out Carrie!" Tylenol wrote. "Just make sure to talk to your doctor before taking Tylenol while you're pregnant."

The CEO behind Tylenol thought he’d found a way to work with the Trump administration. Then everything went off the rails.
