1 INDICATIONS AND USAGE Carefully consider the potential benefits and risks of celecoxib and other treatment options before deciding to use celecoxib.

Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals [ see Warnings and Precautions (5) ] Celecoxib is a non steroidal anti-inflammatory drug indicated for: Osteoarthritis (OA) (1.1) Rheumatoid Arthritis (RA) (1.2) Juvenile Rheumatoid Arthritis (JRA) in patients 2 years and older(1.3) Ankylosing Spondylitis (AS) (1.4) Acute Pain (AP) (1.5) Primary Dysmenorrhea (PD) (1.6) 1.1 Osteoarthritis (OA) Celecoxib is indicated for relief of the signs and symptoms of OA [ see Clinical Studies (14.1) ] 1.2 Rheumatoid Arthritis (RA) Celecoxib is indicated for relief of the signs and symptoms of RA [ see Clinical Studies (14.2) ] 1.3 Juvenile Rheumatoid Arthritis (JRA) Celecoxib is indicated for relief of the signs and symptoms of JRA in patients 2 years and older [ see Clinical Studies (14.3) ] 1.4 Ankylosing Spondylitis (AS) Celecoxib is indicated for the relief of signs and symptoms of AS [ see Clinical Studies (14.4) ] 1.5 Acute Pain (AP) Celecoxib is indicated for the management of AP in adults [ see Clinical Studies (14.5) ] 1.6 Primary Dysmenorrhea (PD) Celecoxib is indicated for the treatment of PD [ see Clinical Studies (14.5) ]

6 ADVERSE REACTIONS 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 twice daily).

Approximately 3,900 patients received celecoxib at these doses for 6 months or more; approximately 2,300 of these have received it for 1 year or more and 124 of these have received it for 2 years or more.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

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.

Most common adverse reactions in arthritis trials (>2% and >placebo): abdominal pain, diarrhea, dyspepsia, flatulence, peripheral edema, accidental injury, dizziness, pharyngitis, rhinitis, sinusitis, upper respiratory tract infection, rash (6.1).

To report SUSPECTED ADVERSE REACTIONS, contact FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Pre-marketing Controlled Arthritis Trials Table 1 lists all adverse events, regardless of causality, occurring in ≥2% of patients receiving celecoxibfrom 12 controlled studies conducted in patients with OA or RA that included a placebo and/or a positive control group.

Since these 12 trials were of different durations, and patients in the trials may not have been exposed for the same duration of time, these percentages do not capture cumulative rates of occurrence.

In placebo- or active-controlled clinical trials, the discontinuation rate due to adverse events was 7.1% for patients receiving celecoxib and 6.1% for patients receiving placebo.

Among the most common reasons for discontinuation due to adverse events in the celecoxib treatment groups were dyspepsia and abdominal pain (cited as reasons for discontinuation in 0.8% and 0.7% of celecoxib patients, respectively).

Among patients receiving placebo, 0.6% discontinued due to dyspepsia and 0.6% withdrew due to abdominal pain.

The following adverse reactions occurred in 0.1 to 1.9% of patients treated with celecoxib (100 to 200 mg twice daily or 200 mg once daily): Gastrointestinal: Constipation, diverticulitis, dysphagia, eructation, esophagitis, gastritis, gastroenteritis, gastroesophageal reflux, hemorrhoids, hiatal hernia, melena, dry mouth, stomatitis, tenesmus, vomiting Cardiovascular: Aggravated hypertension, angina pectoris, coronary artery disorder, myocardial infarction General : Allergy aggravated, allergic reaction, chest pain, cyst NOS, edema generalized, face edema, fatigue, fever, hot flushes, influenza-like symptoms, pain, peripheral pain.

The lower incidence of events with celecoxib was maintained with or without ASA use [ see Clinical Pharmacology (12.2) ].

Withdrawals/Serious Adverse Events: Kaplan-Meier cumulative rates at 9 months for withdrawals due to adverse events for celecoxib, diclofenac and ibuprofen were 24%, 29%, and 26%, respectively.

Rates for serious adverse events (i.e., causing hospitalization or felt to be life-threatening or otherwise medically significant), regardless of causality, were not different across treatment groups (8%, 7%, and 8%, respectively).

6.3 Juvenile Rheumatoid Arthritis Study In a 12-week, double-blind, active-controlled study, 242 JRA patients 2 years to 17 years of age were treated with celecoxib or naproxen; 77 JRA patients were treated with celecoxib 3 mg/kg BID, 82 patients were treated with celecoxib 6 mg/kg BID, and 83 patients were treated with naproxen 7.5 mg/kg BID.

The most commonly occurring (≥5%) adverse events in celecoxib treated patients were headache, fever (pyrexia), upper abdominal pain, cough, nasopharyngitis, abdominal pain, nausea, arthralgia, diarrhea and vomiting.

The most commonly occurring (≥5%) adverse experiences for naproxen-treated patients were headache, nausea, vomiting, fever, upper abdominal pain, diarrhea, cough, abdominal pain, and dizziness (Table 2).

Compared with naproxen, celecoxib at doses of 3 and 6 mg/kg BID had no observable deleterious effect on growth and development during the course of the 12-week double-blind study.

There was no substantial difference in the number of clinical exacerbations of uveitis or systemic features of JRA among treatment groups.

In a 12-week, open-label extension of the double-blind study described above, 202 JRA patients were treated with celecoxib 6 mg/kg BID.

The incidence of adverse events was similar to that observed during the double-blind study; no unexpected adverse events of clinical importance emerged.

Doses up to 400 mg once daily were studied.

The types of adverse events reported in the AS studies were similar to those reported in the OA/RA studies.

Adverse Events from Analgesia and Dysmenorrhea Studies: Approximately 1,700 patients were treated with celecoxib in analgesia and dysmenorrhea studies.

All patients in post-oral surgery pain studies received a single dose of study medication.

Doses up to 600 mg/day of celecoxib were studied in primary dysmenorrhea and post-orthopedic surgery pain studies.

The types of adverse events in the analgesia and dysmenorrhea studies were similar to those reported in arthritis studies.

The only additional adverse event reported was post-dental extraction alveolar osteitis (dry socket) in the post-oral surgery pain studies.

6.5 The APC and PreSAP Trials Adverse reactions from long-term, placebo-controlled polyp prevention studies : Exposure to celecoxib in the APC and PreSAP trials was 400 to 800 mg daily for up to 3 years [ see Special Studies Adenomatous Polyp Prevention Studies (14.6) ].

Some adverse reactions occurred in higher percentages of patients than in the arthritis pre-marketing trials (treatment durations up to 12 weeks; see adverse events from celecoxib pre-marketing controlled arthritis trials , above).

The adverse reactions for which these differences in patients treated with celecoxibwere greater as compared to the arthritis pre-marketing trials were as follows: Celecoxib (400 to 800 mg daily) N=2,285 Placebo N = 1,303 Diarrhea 10.5% 7% Gastroesophageal reflux disease 4.7% 3.1% Nausea 6.8% 5.3% Vomiting 3.2% 2.1% Dyspnea 2.8% 1.6% Hypertension 12.5% 9.8% The following additional adverse reactions occurred in ≥0.1% and <1% of patients taking celecoxib, at an incidence greater than placebo in the long-term polyp prevention studies, and were either not reported during the controlled arthritis pre-marketing trials or occurred with greater frequency in the long-term, placebo-controlled polyp prevention studies: Nervous system disorders: Cerebral infarction Eyedisorders : Vitreous floaters, conjunctival hemorrhage Ear and labyrinth : Labyrinthitis Cardiac disorders : Angina unstable, aortic valve incompetence, coronary artery atherosclerosis, sinus bradycardia, ventricular hypertrophy Vascular disorders : Deep vein thrombosis Reproductive system and breast disorders : Ovarian cyst Investigations : Blood potassium increased,blood sodium increased, blood testosterone decreased Injury, poisoning and procedural complications: Epicondylitis, tendonrupture
