tylenol.com TYLENOL We stand with science, and we stand with you. For generations, families have trusted TYLENOL® when it matters most. Why? Because Tylenol is one of the most studied medications in history. The facts remain unchanged: over a decade of rigorous research, endorsed by leading medical professionals, confirm there is no credible evidence linking acetaminophen to autism. Acetaminophen is used worldwide as a first line of defense for pain relief and fever reduction, at the recommendation of independent public health and leading medical professionals and in accordance with the product label. High fevers and pain are widely recognized as potential risks to a pregnancy if left untreated, especially in the first trimester. Remember to talk to your doctor. We prioritize science as the core of how we provide care, and that will never change.
