The Mystery in the Medicine Cabinet: Acetaminophen, ibuprofen, and what to know

Article note: Huh, I also was under the impression that Ibuprofen was generally safer for frequent low-level use, but that's pretty convincing that Acetaminophen is generally safer except at overdose levels or with certain specific counter-indications. I'd like to see parallel information for some of the other pain relievers like Naproxen (which has generally been my preference for low-level joint pain).
