Naproxen sodium is an internal analgesic available in over-the-counter (OTC) medicines that temporarily relieves minor aches and pains and reduces fever. It also is available in prescription medicines. Naproxen sodium is part of a group of pain relievers and fever reducers called nonsteroidal anti-inflammatory drugs, or NSAIDs. It may be written as naproxen sodium or naproxen, but it is the same active ingredient.
Naproxen sodium can be the only ingredient in oral pain relievers and fever reducers. It also is available in medicines that not only relieve pain or reduce fever, but treat additional symptoms as well, such as the multiple symptoms of the common cold, or symptoms associated with menstruation.
Naproxen sodium is approved by the U.S. Food and Drug Administration (FDA) and is safe and effective when used according to label directions. You should never take more naproxen or for a longer period of time than the label instructs unless your doctor tells you to. Certain health risks such as heart attack, stroke, or stomach bleeding may increase if you use more than directed or for longer than directed.
*Naproxen sodium may not be contained in all products marketed under these brands. Please read the OTC Drug Facts label carefully for active ingredient information for specific products.
