This afternoon I heard a story on NPR via SDPB-Radio indicating that Acetaminophen use alters personality. In effect, it may reduce your ability to "feel others pain". My guess is that particular change may not result in absolutely terrible consequences, but it does raise the question about what else that over-the-counter drug is doing to our brains if we use it. The links below have a bit more information. My guess is that this is not the end of this story.
