Sodium Naproxen
nonsteroidal anti-inflammatory drugs used to relieve mild to moderate pain and menstrual cramps. They are also prescribed for relief of the inflammation, swelling, stiffness, and joint pain associated with rheumatoid arthritis and osteoarthritis (the most common form of arthritis), and for ankylosing spondylitis (spinal arthritis), tendinitis, bursitis, acute gout, and other conditions. Anaprox also may be prescribed for juvenile arthritis
Acetaminophen
Is used to relieve mild to moderate pain from headaches, muscle aches, menstrual periods, colds and sore throats, toothaches, backaches, reactions to vaccinations (shots), and to reduce fever. Acetaminophen may also be used to relieve the pain of osteoarthritis (arthritis caused by the breakdown of the lining of the joints). Acetaminophen is in a class of medications called analgesics (pain relievers) and antipyretics (fever reducers). It works by changing the way the body senses pain and by cooling the body.
Acetaminophen is just the same as Tylenol.
