What is better as anti inflamatory, Advil or Aleve (naproxen) for runners? And how often can we use them without risking complications from overuse?

Also... Agree with dr. Vallury, but also consider that Aleve (naproxen) is longer acting than advil (~12 hours vs. 6-8). Doesn't necessarily work better but longer duration. Never take nsaids prior to long runs (>8 miles or so) because of the risk of low serum sodium and negative effects on your kidneys.
Similar. Both advil and Aleve (naproxen) are nsaids or non-steroidal anti-inflammatory medications. Taken as directed they can can be helpful in improving muscle and joint pain. Never take these medications (or any other medication ) in higher doses or more frequently than recommeded as this can lead to ulcers, kidney failure and other problems.
