US President Donald Trump struggled to pronounce 'acetaminophen' when he linked the consumption of the non-opioid agent during pregnancy with autism in children. "Ah-ced-uv...well, let's see how we say that. Ascenem - enophin. Acetaminophen," he said at the press meet. Acetaminophen, or paracetamol outside US, is sold generally as Tylenol. Notably, experts didn't agree with Trump's claims on it.
