Yes: Excessive non steroidal anti- inflammatory agents such as Aleve (naproxen) or Naproxen can cause interstitial nephritis and lead to kidney dysfunction and possible acute kidney failure. Spilling protein in the urine is an indication that the kidneys are starting to failure. With protein in your urine, stop taking Aleve (naproxen) immediately.

May be too much: Your screen name suggests some advanced aged. Most people 65 pr older should not take nsaids at all. Long term higher dose nsaidshave been associated with hypertension. Higher blood pressure can be hurting your kidneys. Talk to you gp about something other than anti-inflammatoriez for your condition.
