The data described below reflect exposure to mesalamine extended-release capsules in 557 patients, including 354 exposed for at least 6 months and 250 exposed for greater than one year. Mesalamine extended-release capsules were studied in two placebo-controlled trials (n=367 treated with mesalamine extended-release capsules) and in one open-label, long-term study (n=190 additional patients). The population consisted of patients with ulcerative colitis; the mean age was 47 years, 54% were female, and 93% were white. Patients received doses of mesalamine extended-release capsules 1.5 g administered orally once per day for six months in the placebo-controlled trials and for up to 24 months in the open‑label study. In the two placebo-controlled trials, the most common reactions reported in at least 3% of mesalamine extended-release capsules-treated patients and at a greater rate than placebo are shown in Table 1 below. Table 1: Common Adverse Reactions Reported in at least 3% of mesalamine extended-release capsules-treated patients and at a greater rate than with placebo in Clinical Trials of Adults with Ulcerative Colitis Mesalamine Extended-Release Capsules 1.5 g once daily N=367 Placebo N=185 Headache 11% 8% Diarrhea 8% 7% Upper Abdominal Pain 5% 3% Nausea 4% 3% Nasopharyngitis 4% 3% The following adverse reactions, presented by body system, were reported at a frequency less than 3% in patients treated with mesalamine extended-release capsules for up to 24 months in controlled and open-label trials. Ear and Labyrinth Disorders : tinnitus, vertigo Dermatological Disorder : alopecia Gastrointestinal : lower abdominal pain, rectal hemorrhage Laboratory Abnormalities : increased triglycerides, decreased hematocrit and hemoglobin General Disorders and Administration Site Disorders : fatigue Hepatic : hepatitis cholestatic, transaminases increased Renal Disorders : creatinine clearance decreased, hematuria Musculoskeletal : pain, arthralgia Respiratory : dyspnea 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of mesalamine extended-release capsules or other mesalamine-containing products. Because many of these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Body as a Whole : lupus-like syndrome, drug fever Cardiovascular : pericarditis, pericardial effusion, myocarditis [ see Warnings and Precautions (5.3) ] Gastrointestinal : pancreatitis, cholecystitis, gastritis, gastroenteritis, gastrointestinal bleeding, perforated peptic ulcer Hepatic : jaundice, cholestatic jaundice, hepatitis, liver necrosis, liver failure, Kawasaki-like syndrome including changes in liver enzymes Hematologic : agranulocytosis, aplastic anemia Nervous System : intracranial hypertension Neurological/Psychiatric : peripheral neuropathy, Guillain-Barré syndrome, transverse myelitis Renal and Urinary : nephrogenic diabetes insipidus, interstitial nephritis, renal failure, minimal change disease, nephrolithiasis [ see Warnings and Precautions (5.1 , 5.7) ] Urine discoloration occurring ex-vivo caused by contact of mesalamine, including inactive metabolite, with surfaces or water treated with hypochlorite-containing bleach. Respiratory/Pulmonary : eosinophilic pneumonia, interstitial pneumonitis, pleurisy/pleuritis Skin : psoriasis, pyoderma gangrenosum, erythema nodosum, SJS/TEN, DRESS, and AGEP [ see Warnings and Precautions (5.5 )] Renal/Urogenital : reversible oligospermia
