A number of non-peer-reviewed articles have been written and published on the web claiming that there is literally nothing to fear from acetaminophen during pregnancy. There are two types of articles that fall into this category. First, reputable watchdog organizations have weighed in on the issue, declaring acetaminophen use during pregnancy and during childhood to be proven safe. In particular, the National Health Service of the UK and the Center for Accountability in Science have both strongly criticized the Spanish study from 2016 showing a link between acetaminophen use during pregnancy and ADHD/autism.
The second type of article is generally written by a science writer working for an organization that runs a website. Often quoting one to three experts who claim that is perfectly safe and that pregnant women and families should not be concerned, many of these articles are published by reputable sources that are generally trustworthy. Typically, an expert is being asked to comment on one particular publication showing a link between acetaminophen use (usually during pregnancy) and some sort of neuropsychiatric problem (autism, lowered IQ, hyperactivity, and/or social/behavioral problems, depending on the study).
