President Donald Trump’s announcement warning expectant mothers against routine Tylenol use has triggered a wave of viral pushback, with some pregnant women posting videos of themselves swallowing the pills in defiance.

The protest videos began appearing shortly after Trump, alongside Department of Health and Human Services Secretary Robert F. Kennedy Jr. and Centers for Medicare & Medicaid Services Administrator Dr. Mehmet Oz, declared that prenatal acetaminophen use “can be associated with a very increased risk of autism.” He urged women to avoid the drug unless “medically necessary,” citing research flagged by the FDA.
