Naproxen sodium is an internal analgesic available in over-the-counter (OTC) medicines that temporarily relieve minor aches and pains and reduce fever. It is also available in prescription medicines. Naproxen sodium is part of a group of pain relievers and fever reducers called nonsteroidal anti-inflammatory drugs (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 is also available in medicines that treat 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 the Drug Facts label. You should never take more naproxen or for a longer period of time than the label instructs unless your healthcare provider tells you to. Certain health risks such as heart attack, stroke, and stomach bleeding may increase if you use more than directed or for longer than directed.
