I don't take any NSAID, ever. Not ibuprofen, Naproxen, or aspirin. They shut down my kidneys. I was very lucky and my kidneys recovered, but many people aren't so lucky. If you have any unpleasant side effects, you might want to get a CBC to see where your kidney levels are. (Not everybody has my reaction; it was an allergy. But it snuck up on me.)
