Long-Term Acetaminophen Use May Harm Kidneys

Long-term, habitual use of the painkiller acetaminophen, sold under the brand name Tylenol, may cause a decline in kidney function in some people, a study of middle-aged women said on Monday. Overall, one in 10 of the 1,700 women studied over 11 years experienced a 30 percent decline in their kidney's filtration function. Acetaminophen, which is sold as Tylenol by a subsidiary of Johnson & Johnson and also marketed generically, was alone among commonly used painkillers to show an association with kidney impairment.
