• DOSAGE AND ADMINISTRATION Use the lowest effective dosage for shortest duration consistent with individual patient treatment goals. ( 2.1 ) OA: 200 mg once daily or 100 mg twice daily. ( 2.2 , 14.1 ) RA: 100 mg to 200 mg twice daily. ( 2.3 , 14.2 ) JRA: 50 mg twice daily in patients 10 kg to 25 kg. 100 mg twice daily in patients more than 25 kg. ( 2.4 , 14.3 ) AS: 200 mg once daily single dose or 100 mg twice daily. If no effect is observed after 6 weeks, a trial of 400 mg (single or divided doses) may be of benefit. ( 2.5 , 14.4 ) AP and PD: 400 mg initially, followed by 200 mg dose if needed on first day. On subsequent days, 200 mg twice daily as needed. ( 2.6 , 14.5 ) Hepatic Impairment: Reduce daily dose by 50% in patients with moderate hepatic impairment (Child-Pugh Class B). ( 2.7 , 8.6 , 12.3 ) Poor Metabolizers of CYP2C9 Substrates: Consider a dose reduction by 50% (or alternative management for JRA) in patients who are known or suspected to be CYP2C9 poor metabolizers. ( 2.7 , 8.8 , 12.3 ). 2.1 General Dosing Instructions Carefully consider the potential benefits and risks of celecoxib and other treatment options before deciding to use celecoxib. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [ see Warnings and Precautions (5) ]. These doses can be given without regard to timing of meals. 2.2 Osteoarthritis For OA, the dosage is 200 mg per day administered as a single dose or as 100 mg twice daily. 2.3 Rheumatoid Arthritis For RA, the dosage is 100 mg to 200 mg twice daily. 2.4 Juvenile Rheumatoid Arthritis For JRA, the dosage for pediatric patients (age 2 years and older) is based on weight. For patients > 10 kg to < 25 kg the recommended dose is 50 mg twice daily. For patients >25 kg the recommended dose is 100 mg twice daily. For patients who have difficulty swallowing capsules, the contents of a celecoxib capsule can be added to applesauce. The entire capsule contents are carefully…

12.2 Pharmacodynamics Platelets In clinical trials using normal volunteers, celecoxib at single doses up to 800 mg and multiple doses of 600 mg twice daily for up to 7 days duration (higher than recommended therapeutic doses) had no effect on reduction of platelet aggregation or increase in bleeding time. Because of its lack of platelet effects, celecoxib is not a substitute for aspirin for cardiovascular prophylaxis. It is not known if there are any effects of celecoxib on platelets that may contribute to the increased risk of serious cardiovascular thrombotic adverse events associated with the use of celecoxib. Fluid Retention Inhibition of PGE2 synthesis may lead to sodium and water retention through increased reabsorption in the renal medullary thick ascending loop of Henle and perhaps other segments of the distal nephron. In the collecting ducts, PGE2 appears to inhibit water reabsorption by counteracting the action of antidiuretic hormone.

• ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Cardiovascular Thrombotic Events [ see Warnings and Precautions ( 5.1 ) ] GI Bleeding, Ulceration and Perforation [ see Warnings and Precautions ( 5.2 ) ] Hepatotoxicity [ see Warnings and Precautions ( 5.3 ) ] Hypertension [ see Warnings and Precautions ( 5.4 ) ] Heart Failure and Edema [ see Warnings and Precautions ( 5.5 ) ] Renal Toxicity and Hyperkalemia [ see Warnings and Precautions ( 5.6 ) ] Anaphylactic Reactions [ see Warnings and Precautions ( 5.7 ) ] Serious Skin Reactions [ see Warnings and Precautions ( 5.9 ) ] Hematologic Toxicity [ see Warnings and Precautions ( 5.12 ) ] Most common adverse reactions in arthritis trials (>2% and > placebo) are: abdominal pain, diarrhea, dyspepsia, flatulence, peripheral edema, accidental injury, dizziness, pharyngitis, rhinitis, sinusitis, upper respiratory tract infection, rash.

The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates. Of the celecoxib-treated patients in the pre-marketing controlled clinical trials, approximately 4,250 were patients with OA, approximately 2,100 were patients with RA, and approximately 1,050 were patients with post-surgical pain. More than 8,500 patients received a total daily dose of celecoxib of 200 mg (100 mg twice daily or 200 mg once daily) or more, including more than 400 treated at 800 mg (400 mg…

• WARNINGS AND PRECAUTIONS Hepatotoxicity: Inform patients of warning signs and symptoms of hepatotoxicity. Discontinue if abnormal liver tests persist or worsen or if clinical signs and symptoms of liver disease develop. ( 5.3 ) Hypertension: Patients taking some antihypertensive medications may have impaired response to these therapies when taking NSAIDs. Monitor blood pressure. ( 5.4 , 7 ) Heart Failure and Edema: Avoid use of celecoxib in patients with severe heart failure unless benefits are expected to outweigh risk of worsening heart failure. ( 5.5 ) Renal Toxicity: Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia. Avoid use of celecoxib in patients with advanced renal disease unless benefits are expected to outweigh risk of worsening renal function. ( 5.6 ) Anaphylactic Reactions: Seek emergency help if an anaphylactic reaction occurs. ( 5.7 ) Exacerbation of Asthma Related to Aspirin Sensitivity: Celecoxib is contraindicated in patients with aspirin-sensitive asthma. Monitor patients with preexisting asthma (without aspirin sensitivity). ( 5.8 ) Serious Skin Reactions: Discontinue celecoxib at first appearance of skin rash or other signs of hypersensitivity. ( 5.9 ) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): Discontinue and evaluate clinically. ( 5.10 ) Fetal Toxicity: Limit use of NSAIDs, including celecoxib, between about 20 to 30 weeks in pregnancy due to the risk of oligohydramnios/fetal renal dysfunction. Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy due to the risks of oligohydramnios/fetal renal dysfunction and premature closure of the fetal ductus arteriosus. ( 5.11 , 8.1 ) Hematologic Toxicity: Monitor hemoglobin or hematocrit in patients with any signs or symptoms of anemia. ( 5.12 , 7 ) 5.1 Cardiovascular Thrombotic Events Clinical trials of several cyclooxygenase-2 (COX-2) selective and nonselective NSAIDs of up to three years…

• DRUG INTERACTIONS See Table 3 for clinically significant drug interactions with celecoxib. Table 3: Clinically Significant Drug Interactions with Celecoxib Drugs That Interfere with Hemostasis Clinical Impact: Celecoxib and anticoagulants such as warfarin have a synergistic effect on bleeding. The concomitant use of celecoxib and anticoagulants have an increased risk of serious bleeding compared to the use of either drug alone. Serotonin release by platelets plays an important role in hemostasis. Case-control and cohort epidemiological studies showed that concomitant use of drugs that interfere with serotonin reuptake and an NSAID may potentiate the risk of bleeding more than an NSAID alone. Intervention: Monitor patients with concomitant use of celecoxib with anticoagulants (e.g., warfarin), antiplatelet drugs (e.g., aspirin), SSRIs, and SNRIs for signs of bleeding [see Warnings and Precautions (5.12) ]. Aspirin Clinical Impact: Controlled clinical studies showed that the concomitant use of NSAIDs and analgesic doses of aspirin does not produce any greater therapeutic effect than the use of NSAIDs alone. In a clinical study, the concomitant use of an NSAID and aspirin was associated with a significantly increased incidence of GI adverse reactions as compared to use of the NSAID alone [ see Warnings and Precautions (5.2) ]. In two studies in healthy volunteers, and in patients with osteoarthritis and established heart disease respectively, celecoxib (200 mg to 400 mg daily) has demonstrated a lack of interference with the cardioprotective antiplatelet effect of aspirin (100 mg to 325 mg). Intervention: Concomitant use of celecoxib and analgesic doses of aspirin is not generally recommended because of the increased risk of bleeding [see Warnings and Precautions (5.12) ]. Celecoxib is not a substitute for low dose aspirin for cardiovascular protection. ACE Inhibitors, Angiotensin Receptor Blockers, and Beta-Blockers Clinical Impact: NSAIDs may diminish the…
