Using Naproxen for Chronic Pain Management

Naproxen is the generic name for a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat mild to moderate pain and inflammation. It is available for over-the-counter purchase, however, stronger prescription formulations are also available for more severe pain. Naproxen is often used to treat pain for such conditions as arthritis, bursitis, ankylosing spondylitis, tendonitis, gout, or menstrual cramps. Naproxen may also be known under the following brand names:

• Aleve
• Anaprox
• Naprosyn
• Naprelan

How Naproxen Works

Naproxen, like other NSAIDs, works to decrease swelling and to inhibit pain sensations. Naproxen reduces hormones that cause inflammation and chronic pain. The exact way it works is not completely understood. However, researchers believe it plays a role in inhibiting a substance called prostaglandin, which is associated with pain.
