Adverse reaction data were derived from patients who received oxaprozin in multidose, controlled, and open-label clinical trials.

Rates for events from clinical trial experience are based on 2,253 patients who took 1,200 mg to 1,800 mg oxaprozin per day in clinical trials.

Of these, 1,721 patients were treated for at least 1 month, 971 patients for at least 3 months, and 366 patients for more than 1 year.

Incidence Greater than 1% : In clinical trials of oxaprozin or in patients taking other NSAIDs, the following adverse reactions occurred at an incidence greater than 1%.

Cardiovascular system: edema.

Digestive system: abdominal pain/distress, anorexia, constipation, diarrhea, dyspepsia, flatulence, gastrointestinal ulcers (gastric/duodenal), gross bleeding/perforation, heartburn, liver enzyme elevations, nausea, vomiting.

Hematologic system: anemia, increased bleeding time.

Nervous system: CNS inhibition (depression, sedation, somnolence, or confusion), disturbance of sleep, dizziness, headache.

Urogenital: cystitis, hematuria, increase in menstrual flow, oliguria/ polyuria, proteinuria, renal insufficiency, decreased menstrual flow.

6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of oxaprozin.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Body as a whole: serum sickness.

Digestive system: hepatitis, pancreatitis.

Hematologic system: agranulocytosis, pancytopenia.

Skin: pseudoporphyria, exfoliative dermatitis, erythema multiforme, Stevens-Johnson Syndrome, fixed drug eruption (FDE), toxic epidermal necrolysis (Lyell’s syndrome).
