1 Do not take Aleve if you have ever had an allergic reaction to any other pain reliever/fever reducer.  Naproxen sodium may cause a severe allergic reaction, especially in people allergic to aspirin. Symptoms may include hives, facial swelling, asthma (wheezing), shock, skin reddening, rash or blisters. If an allergic reaction occurs, stop use and seek medical help right away.
