Ignorance about ingredients found in more than 600 over-the-counter and prescription drugs could account for increasing liver failure, U.S. researchers say.
Senior author Michael Wolf of Northwestern University Feinberg School of Medicine in Chicago says his study found only 31 percent of participants knew Tylenol contained acetaminophen; 75 percent of participants knew Bayer contained aspirin; 47 percent knew Motrin contained ibuprofen; 19 percent knew Aleve contained naproxen sodium and 19 percent knew Advil contained ibuprofen.
