Wording differs between labels, and the full indications section on this page takes precedence when it is present.

1 INDICATIONS AND USAGE Oxaprozin tablets are 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 Oxaprozin is a non-steroidal anti-inflammatory drug indicated for: Relief of signs and symptoms of Osteoarthritis (OA) (1) Relief of signs and symptoms of Rheumatoid Arthritis (RA) (1) Relief of signs and symptoms of Juvenile Rheumatoid Arthritis (JRA) (1)

2 DOSAGE AND ADMINISTRATION Use the lowest effective dosage for shortest duration consistent with individual patient treatment goals (2.1) OA: 1200 mg (two 600 mg tablets) given orally once a day ( 2.2 , 2.5 , 14.1 ) RA: 1200 mg (two 600 mg tablets) given orally once a day ( 2.3 , 2.5 , 14.2 ) JRA: 600 mg once daily in patients 22 to 31 kg. 900 mg once daily in patients 32 to 54 kg. 1200 mg once daily in patients ≥ 55 kg ( 2.4 , 2.5) 2.1 General Dosing Instructions Carefully consider the potential benefits and risks of oxaprozin tablets and other treatment options before deciding to use oxaprozin tablets. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [ see Warnings and Precautions (5) ]. 2.2 Osteoarthritis For OA, the dosage is 1,200 mg (two 600 mg tablets) given orally once a day [ see Dosage and Administration ( 2.5 ) ]. 2.3 Rheumatoid Arthritis For RA, the dosage is 1,200 mg (two 600 mg tablets) given orally once a day [ see Dosage and Administration ( 2.5 ) ] . 2.4 Juvenile Rheumatoid Arthritis For JRA, in patients 6 to 16 years of age, the recommended dosage given orally once per day should be based on body weight of the patient as given in Table 1 [ see Dosage and Administration (2.5 ) ]. Table 1. Recommended Daily Dose of Oxaprozin Tablets by Body Weight in Pediatric Patients Body Weight Range (kg) Dose (mg) 22 to 31 600 32 to 54 900 ≥55 1200 2.5 Individualization of Dosage After observing the response to initial therapy with oxaprozin tablets, the dose and frequency should be adjusted to suit an individual patient’s needs. In osteoarthritis and rheumatoid arthritis and juvenile rheumatoid arthritis, the dosage should be individualized to the lowest effective dose of oxaprozin tablets to minimize adverse effects. The maximum recommended total daily dose of oxaprozin tablets in adults is 1,800 mg (26 mg/kg, whichever is lower) in divided doses. In children, doses greater than 1,200 mg have not been studied. Patients with low body weight should initiate therapy with 600 mg once daily. Patients with severe renal impairment or on dialysis should also initiate therapy with 600 mg once daily. If there is insufficient relief of symptoms in such patients, the dose may be cautiously increased to 1,200 mg, but only with close monitoring [ see Clinical Pharmacology ( 12.3 ) ]. In adults, in cases where a quick onset of action is important, the pharmacokinetics of oxaprozin allows therapy to be started with a one-time loading dose of 1,200 mg to 1,800 mg (not to exceed 26 mg/kg). Doses larger than 1,200 mg/day on a chronic basis should be reserved for patients who weigh more than 50 kg, have normal renal and hepatic function, are at low risk of peptic ulcer, and whose severity of disease justifies maximal therapy. Physicians should ensure that patients are tolerating doses in the 600 mg to 1,200 mg/day range without gastroenterologic, renal, hepatic, or dermatologic adverse effects before advancing to the larger doses. Most patients will tolerate once-a-day dosing with oxaprozin tablets, although divided doses may be tried in patients unable to tolerate single doses.

4 CONTRAINDICATIONS Oxaprozin tablets are contraindicated in the following patients: Known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to oxaprozin or any components of the drug product [see Warnings and Precautions ( 5.7 , 5.9 ) ] History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs.

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. Skin and appendages: pruritus, rash. Special senses: tinnitus. Urogenital system: abnormal renal function, dysuria or frequency. Incidence Greater than 1%: The following adverse reactions were reported in clinical trials or in patients taking other NSAIDs. Body as a whole: appetite changes, death, drug hypersensitivity reactions including anaphylaxis, fever, infection, sepsis. Cardiovascular system: arrhythmia, blood pressure changes, congestive heart failure, hypertension, hypotension, myocardial infarction, palpitations, tachycardia, syncope, vasculitis.

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). Urogenital: acute interstitial nephritis, nephrotic syndrome, acute renal failure.
