Where I live, tylenol is generally seen as less effective and less risky than aspirin or advil. I wonder how many pregnant mothers have taken it in a misguided attempt to reduce the risk of side effects.

Acetaminophen is often recommended for pregnant women because NSAIDs carry risks in pregnancy that have been known for far longer. Indeed, the researchers here indicate that they recommend judicious use, not "broad limitation" because failing to manage fevers during pregnancy also carries risk. So there is no good option, only an understanding that all the options carry drawbacks and that we should go into maternal healthcare with our eyes open.
