“They are strongly recommending that women limit Tylenol use during pregnancy unless medically necessary,” such as to treat fever, “if you can’t tough it out,” Trump was quoted as saying by CNN. The precautionary principle may lead many to avoid using acetaminophen during pregnancy, especially since most low-grade fevers don’t require treatment. “Any association between acetaminophen and autism is based on limited, conflicting, and inconsistent science and is premature,” said Autism Science Foundation Chief Science Officer Dr Alycia Halladay. Instead, President Trump talked about what he thinks and feels without offering scientific evidence. If you can’t take the pain or deal with a fever, then it’s your fault if your child has autism.
