FAKE
Tylenol did not issue a warning against use during pregnancy in 2017. Recent discussions about potential risks associated with acetaminophen use during pregnancy have emerged, but no such warning was in place at that time. Tylenol, which contains acetaminophen, has been widely recommended for pain relief during pregnancy. It is considered one of the few safe over-the-counter medications for treating pain and fever in pregnant women.
No definitive causal relationship has been established for increased risks of conditions like autism and ADHD.
Kids were born with autism long before Tylenol was even invented. ¯\_(ツ)_/¯
