Safe painkiller during pregnancy

Explaining why evidence argues that acetaminophen (tylenol) does not

cause asperger's syndrome, but that rather genes that make women more

likely to need a painkiller during pregnancy also make

asperger's syndrome a little bit more likely

— whether they use acetaminophen or not.

In any case, the effect is so small mdash; 0.2% of the babies they have —

that one shouldn't worry about it.
