Studies on perinatal acetaminophen exposure in rodents have shown inconsistent neurodevelopmental abnormalities, often not aligning with autism characteristics.

“And while we have some data here, they're very inconsistent um to the question. So, you know, there are some studies that involve pre- or perinatal acetaminophen exposure in mice and rats that have reported a few neurodedevelopmental abnormalities, but they've been very inconsistent in the nature of the effect.”

“But it's important to note that both the FDA and the scientific community agree that we don't yet have evidence to assert that the apparent correlations between prenatal acetaminophen exposure and autism risk reflect a causal relationship.”

“The mechanism of action for acetammenophen is generally pretty poorly understood. It's kind of amazing that we don't understand how such a ubiquitous drug actually lowers temperature and alleviates pain. So therefore, we don't really have uh much clarity on how it might ultimately lead to autism. That said, um its effects are mediated at least in part through inhibition of the synthesis of prostaglandins, which are molecules that contribute to pain and the inflammatory response. And since prostaglandins also play a role in neurode development, some re researchers have argued um that acetaminophen leads to autism by disrupting neurodedevelopmental pathways.”
