Naprosyn, a nonsteroidal anti-inflammatory drug, is used to relieve the inflammation, swelling, stiffness, and joint pain associated with rheumatoid arthritis, osteoarthritis (the most common form of arthritis), juvenile arthritis, ankylosing spondylitis (spinal arthritis), tendinitis, bursitis, and acute gout; it is also used to relieve menstrual cramps and other types of mild to moderate pain.
Naprosyn may be taken with food or an antacid, and with a full glass of water to avoid stomach upset. Avoid taking it on an empty stomach.
If you are using Naprosyn for arthritis, it should be taken regularly; take it exactly as prescribed.
