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

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.

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.
