For Healthcare Professionals
Applies to oxaprozin: oral tablet
Patients with a history of serious gastrointestinal events or alcohol abuse are at increased risk for severe gastrointestinal side effects. Oxaprozin should be used with caution in these patients.
Gastrointestinal side effects associated with oxaprozin include nausea (8%), dyspepsia (8%), diarrhea (3% to 9%), constipation (3% to 9%), anorexia, vomiting, and flatulence. More serious gastrointestinal effects such as peptic ulceration, gastrointestinal bleeding, and rectal bleeding have been reported.
Hepatic side effects include elevations in serum transaminases in up to 12% of patients. Hepatitis has been reported in less than 1% of patients. A case of fatal, fulminant hepatitis has been reported with oxaprozin use.
Elevations in liver function tests three times normal values occurred in 1.4% of patients treated with oxaprozin.
While oxaprozin-induced elevations in liver function tests are usually mild and transient, fatal hepatitis has been reported with oxaprozin. Patients who develop persistent or significant elevations in liver function tests and/or signs or symptoms suggestive of hepatic dysfunction should be evaluated for more severe hepatotoxicity.
Renal side effects include interstitial nephritis, membranous nephropathy, hematuria, nephrotic syndrome, oliguria/polyuria, proteinuria, and acute renal failure.
Oxaprozin may impair the ability of the kidney to cope with low renal blood flow states due to inhibition of prostaglandin-dependent afferent arteriolar vasodilation. Renal function may be further compromised in patients with heart failure, hypovolemia, cirrhosis, nephrotic syndrome, or hypoalbuminemia. Additional risk factors for oxaprozin-induced renal insufficiency are advanced age and concomitant use of diuretics.
A case-control study suggested that patients who consumed 5000 or more pills containing NSAIDs during their lifetime may be at increased risk of end-stage renal disease.
Cardiovascular side effects have included fluid retention and edema which may be important in patients with heart failure. In addition, blood pressure may be elevated by oxaprozin which may have clinical relevance in patients with comorbid illnesses.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may elevate blood pressure and increase the risk for the initiation of antihypertensive therapy. Furthermore, NSAIDs may antagonize the blood pressure lowering effect of antihypertensive medications in patients already being treated with antihypertensive drugs.
Nervous system side effects have included depression (i.e. sedation, somnolence, confusion, and depression), sleep disturbances, weakness, fatigue, headache, and vertigo have been reported.
Dermatologic side effects have included rash (3% to 9%), alopecia, pruritus, exfoliative dermatitis, pseudoporphyria, erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis (Lyell's syndrome). Photosensitivity characterized by vesicular eruptions has been reported. Pseudoporphyria, or bullous photosensitivity, has also been reported. Angioedema and sweat have been reported in patients taking other NSAIDs.
Hematologic side effects have included agranulocytosis, pancytopenia, anemia, thrombocytopenia, leukopenia, and ecchymoses. Prolonged bleeding time may occur as well.
Hypersensitivity reactions occur in less than 1% of patients and may manifest as urticaria and anaphylaxis.
Other side effects of oxaprozin include tinnitus, blurred vision, and conjunctivitis. In addition, oxaprozin may cause a false positive result on urine drug screening for benzodiazepines.
Psychiatric disturbances, including confusion, delusions, depression, hallucinations, paranoid reactions, and panic disorders, although rare, have been noted with oxaprozin use.
Genitourinary side effects have included an increase or decrease in menstrual flow in less than 1% of patients.
Respiratory side effects (<1%) have included asthma, dyspnea, respiratory depression, sinusitis, symptoms of upper respiratory tract infection, pulmonary infections, and pneumonia.
