This is of interest if you have ADD or ADHD, and of concern if you are pregnant or at risk for pregnancy (I chose that term deliberately, a little touch of humor?). This is an example of the murkiness and risks of science (and includes a little bit of the risk of confusing correlation with cause).
This is only one study, and can almost not properly be called science yet, since a study needs to be replicated by a number of independent researchers, before you can legitimately claim “science says —“.
But our media picks it up and sensationalizes it, because alarms and catastrophes and sensational sells.
Given all that, if I were pregnant, I probably would avoid Tylenol now, awaiting some more information. However, if further studies refute this one, don’t expect to see headlines in all the major media, “Tylenol proven safe!” Corrections are usually in small print on the third page, if printed at all.
And aside from that, we all need to be concerned about the air we’re breathing and the water we’re drinking – God only knows what’s in those.
Keep well.
