What is oxaprozin? What is oxaprozin used for?
Oxaprozin belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Other members of this class include ibuprofen (Motrin), indomethacin (Indocin), naproxen (Aleve) and several others. These drugs are used for the management of mild to moderate pain, fever and inflammation.
Oxaprozin is indicated:
- For relief of the signs and symptoms of osteoarthritis
- For relief of the signs and symptoms of rheumatoid arthritis
- For relief of the signs and symptoms of juvenile rheumatoid arthritis
NSAIDs work by reducing the levels of prostaglandins, chemicals that are responsible for pain, fever, and inflammation. Oxaprozin blocks the enzyme that makes prostaglandins (cyclooxygenase), resulting in lower concentrations of prostaglandins. As a consequence, inflammation, pain and fever are reduced. The FDA approved oxaprozin in October 1992.

What are the side effects of oxaprozin?
The most common side effects from oxaprozin are rash, ringing in the ears, headaches, dizziness, drowsiness, abdominal pain, nausea, diarrhea, constipation, heartburn, fluid retention, and shortness of breath.
NSAIDs reduce the ability of blood to clot and therefore increase bleeding after an injury. Oxaprozin also may cause bleeding in the stomach and intestine as well as ulcers. Sometimes, stomach ulceration and intestinal bleeding can occur without any abdominal pain. Black tarry stools, weakness, and dizziness upon standing may be the only signs of the bleeding.
People who are allergic to other NSAIDs should not use oxaprozin. NSAIDs reduce the flow of blood to the kidneys and impair function of the kidneys. The impairment is most likely to occur in patients with preexisting impairment of kidney function or congestive heart failure, and use of NSAIDs in these patients should be done cautiously. Individuals with asthma are more likely to experience allergic reactions to oxaprozin and other NSAIDs. Fluid retention, blood clots, heart attacks, hypertension, and heart failure also have been associated with the use of NSAIDs.
What is the dosage for oxaprozin?
The usual dose of oxaprozin is 600 or 1200 mg once daily taken with food. The maximum dose is 1800 mg daily. The total daily dose may be divided into multiple doses if single daily doses are not tolerated.
Which drugs or supplements interact with oxaprozin?
Oxaprozin may reduce the blood pressure lowering effects of blood pressure medications. This may occur because prostaglandins play a role in the regulation (reduction) of blood pressure.
When oxaprozin is used in combination with methotrexate (Rheumatrex, Trexall) or aminoglycoside antibiotics (for example, gentamicin) the blood levels of methotrexate or aminoglycoside may increase, presumably because the elimination of methotrexate or aminoglycoside is reduced. This may lead to more side effects from methotrexate or aminoglycoside.
Individuals taking oral blood thinners or anticoagulants, for example, warfarin, (Coumadin), should avoid oxaprozin because oxaprozin also thins the blood, and excessive blood thinning may lead to bleeding.
Oxaprozin increases the negative effect of cyclosporine on kidney function.
If aspirin is taken with oxaprozin there may be an increased risk for developing an ulcer.
Persons who have more than 3 alcoholic beverages per day may be at increased risk of developing stomach ulcers when taking oxaprozin or other NSAIDs.

Related Disease Conditions
Rheumatoid Arthritis (RA)
Rheumatoid arthritis (RA) is an autoimmune disease resulting in chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Early RA signs and symptoms include anemia, both sides of the body affected (symmetric), depression, fatigue, fever, joint deformity, joint pain, joint redness, joint stiffness, joint swelling, joint tenderness, joint warmth, limping, loss of joint function, loss of joint range of motion, and polyarthritis.
Arthritis (Joint Inflammation)
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, and pseudogout.
Osteoarthritis is a type of arthritis caused by inflammation, breakdown, and eventual loss of cartilage in the joints. Also known as degenerative arthritis, osteoarthritis can be caused by aging, heredity, and injury from trauma or disease.
Pain management and treatment can be simple or complex, according to its cause. There are two basic types of pain, nociceptive pain and neuropathic pain. Some causes of neuropathic pain include: complex regional pain syndrome, interstitial cystitis, and irritable bowel syndrome. There are a variety of methods to treat chronic pain, which are dependant on the type of pain experienced.
Nonsteroidal Anti-inflammatory Drugs and Ulcers
Nonsteroidal anti-inflammatory drugs (NSAIDs) are prescribed medications for the treatment of inflammatory conditions. Examples of NSAIDs include aspirin, ibuprofen, naproxen, and more. One common side effect of NSAIDs is peptic ulcer (ulcers of the esophagus, stomach, or duodenum). Side effects, drug interactions, warnings and precautions, and patient safety information should be reviewed prior to taking NSAIDs.
Chronic pain is pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments.
