Pain Home > Naprosyn

Naprosyn, a pain-relief medication, is commonly prescribed to treat symptoms of arthritis and other forms of bone, muscle, or tendon pain. Besides alleviating pain, the medicine is also effective at reducing fever, joint swelling, and inflammation caused by injuries or other conditions. Naprosyn is available in two forms, immediate-release and delayed-release, and comes in a variety of strengths. Side effects of the drug can include abdominal pain (or stomach pain), headache, nausea, and drowsiness.

What Is Naprosyn?

Naprosyn® (naproxen) is a prescription medicine used to reduce pain, inflammation, fever, and stiffness caused by many conditions, including injury, arthritis, gout, menstrual cramps, and other types of bone, muscle, or tendon pain. Naprosyn is part of a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It comes in two forms -- Naprosyn (immediate-release) and EC-Naprosyn® (delayed-release).

Who Makes Naprosyn?

It is manufactured by Roche Pharmaceuticals.

What Is It Used For?

Naprosyn uses include:
  • Pain relief, such as for pain following a medical procedure, from straining a muscle, or caused by inflammation in a tendon (tendonitis) or bursa (bursitis). It can also be used to treat general pain, such as lower back pain, neck pain, or knee pain. EC-Naprosyn is generally not recommended for the treatment of this type of pain because its effects are delayed compared to immediate-release Naprosyn.
  • Treatment of arthritis symptoms, including pain, stiffness, and swelling. Naprosyn can be used to treat several different types of arthritis, including osteoarthritis, rheumatoid arthritis, juvenile arthritis (also known as juvenile rheumatoid arthritis), ankylosing spondylitis, and gout. It does not cure these types of arthritis or affect their progression.
  • Treatment of painful menstrual periods.
