Q. I am a 16-year-old girl who has had bladder problems since I was eight. I was taken to the hospital for pain in my left hip and the doctor prescribed two pills (500 mg) of naproxen to be taken twice daily.
I had pain in my stomach and back and couldn’t sleep. Then my urinary system shut down completely. I had taken the drug for almost three weeks before another doctor took me off. I was in the hospital for seven weeks and was just released with no improvement.
I know the drug did this to me. Has anyone else had this severe reaction?
A. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as naproxen can harm the kidneys (Pharmacoepidemiology and Drug Safety, Oct., 2009). A recent study of marathon runners found that those who took ibuprofen before the race to ward off muscle soreness were more likely to develop temporary kidney failure as a result (BMJ Open, online April 19, 2013). Your story is a reminder that pain relievers may have serious side effects.
