Just forget autism for a moment. Acetaminophen is well known to be associated with neurodevelopmental harm in fetuses, and that's enough reason to avoid it during a pregnancy. Here are some random scientific articles on it: Association of Cord Plasma Biomarkers of In Utero Acetaminophen Exposure With Risk of Attention-Deficit/Hyperactivity Disorder and Autism Spectrum Disorder in Childhood (2019): https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2753512 https://jamanetwork.com/journals/jamapsychiatry/fullarticle/... Association of Prenatal Acetaminophen Exposure Measured in Meconium With Risk of Attention-Deficit/Hyperactivity Disorder Mediated by Frontoparietal Network Brain Connectivity (2020): https://jamanetwork.com/journals/jamapediatrics/fullarticle/2770802 https://jamanetwork.com/journals/jamapediatrics/fullarticle/... Examining the relationship of acetaminophen use during pregnancy with early language development in children (2024): https://www.nature.com/articles/s41390-023-02924-4 https://www.nature.com/articles/s41390-023-02924-4 It is possible that there are correlated causative factors, e.g. fever, infection, etc. This makes the flu shot more important than ever in advance of a pregnancy. Even so, is the repeated use of acetaminophen really a risk worth taking? It probably isn't. We seem to lack the vocabulary to make a 10-20 year national experiment of avoidance to see what happens, if the rates go down or not.
