What drugs? Pregnant women can’t take NSAIDs, especially in the second and third trimesters. they are definitively linked to pregnancy complications and are only rarely used if the benefits outweigh the risks

If there is a risk with Tylenol (there probably isn’t but there’s some conflicting evidence though some of the supporting evidence has some baggage - the Harvard study in particular having a pretty notable financial conflict of interest) the risk is likely greatly outweighed by not taking Tylenol, as maternal pain and uncontrolled fever are definitely linked to birth defects

It’s an issue because if it is true then the evidence needs to be much more significant. If it is not true then they are scaring the layperson into a standard of care that is going to result in significantly worse outcomes because they followed the advice of the government. You may be like “oh that’s stupid, I’m gonna take Tylenol” but I guarantee you there’s a bunch of pregnant women right now that are in pain, that have a fever of 100F, etc who are risking neurological and other birth defects
