warnings and cautions

5 WARNINGS AND PRECAUTIONS Development of Renal Impairment (for example, minimal change nephropathy, acute and chronic interstitial nephritis renal failure): Assess renal function at beginning of treatment and periodically during therapy ( 5.1 ) Mesalamine-induced Acute Intolerance Syndrome: Has been reported. Observe patients closely for worsening of these symptoms while on treatment ( 5.2 ) Hypersensitivity Reactions: Use caution when treating patients who are hypersensitive to sulfasalazine. Mesalamine-induced cardiac hypersensitivity reactions (myocarditis and pericarditis) have been reported ( 5.3 ) Hepatic Failure: Has been reported in patients with pre-existing liver disease. Use caution when treating patients with liver disease ( 5.4 ) Prolonged Gastric Retention in Patients with Upper Gastrointestinal Obstruction: May lead to a delay in onset of action ( 5.5 ) 5.1 Renal Impairment Renal impairment, including minimal change nephropathy, acute and chronic interstitial nephritis, and, rarely, renal failure, has been reported in patients taking products such as delayed-release tablets that contain or are converted to mesalamine. It is recommended that all patients have an evaluation of renal function prior to initiation of Mesalamine delayed-release tablets and periodically while on therapy. Prescribers should carefully evaluate the risks and benefits when using Mesalamine delayed-release tablets in patients with known renal impairment or history of renal disease [see Drug Interactions ( 7.1 ) and Nonclinical Toxicology ( 13.2 )]. 5.2 Mesalamine-Induced Acute Intolerance Syndrome Mesalamine has been associated with an acute intolerance syndrome that may be difficult to distinguish from an exacerbation of ulcerative colitis. Exacerbation of the symptoms of colitis has been reported in 2.3 percent of Mesalamine delayed-release tablets-treated patients in controlled clinical trials. This acute reaction, characterized by cramping, abdominal pain, bloody diarrhea, and occasionally by fever, headache, malaise, pruritus, rash, and conjunctivitis, has been reported after the initiation of Mesalamine delayed-release tablets as well as other mesalamine products. Symptoms usually abate when Mesalamine delayed-release tablets are discontinued. 5.3 Hypersensitivity Reactions Some patients who have experienced a hypersensitivity reaction to sulfasalazine may have a similar reaction to Mesalamine delayed-release tablets or to other compounds that contain or are converted to mesalamine. Mesalamine-induced cardiac hypersensitivity reactions (myocarditis and pericarditis) have been reported with Mesalamine delayed-release tablets and other mesalamine medications. Caution should be taken in prescribing this medicine to patients with conditions predisposing them to the development of myocarditis or pericarditis. 5.4 Hepatic Failure There have been reports of hepatic failure in patients with pre-existing liver disease who have been administered mesalamine. Caution should be exercised when administering Mesalamine delayed-release tablets to patients with liver disease. 5.5 Prolonged Gastric Retention in Patients with Upper Gastrointestinal Obstruction Organic or functional obstruction in the upper gastrointestinal tract may cause prolonged gastric retention of Mesalamine delayed-release tablets which would delay release of mesalamine in the colon.

adverse reactions

6 ADVERSE REACTIONS The most serious adverse reactions seen in Mesalamine delayed-release tablets clinical trials or with other products that contain mesalamine or are metabolized to mesalamine were: Renal impairment, including renal failure (rare) [see Warnings and Precautions ( 5.1 )] Acute intolerance syndrome [see Warnings and Precautions ( 5.2 )] Hypersensitivity reactions [see Warnings and Precautions ( 5.3 )] Hepatic failure [see Warnings and Precautions ( 5.4 )] The most common adverse reactions (observed in greater than 2 percent of patients) were headache, nausea, nasopharyngitis, abdominal pain, and worsening of ulcerative colitis ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Zydus Pharmaceuticals USA Inc. at 1-877-993-8779 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience 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. Mesalamine delayed-release tablets have been evaluated in 896 patients with ulcerative colitis in controlled studies. Three six-week, active-controlled studies were conducted comparing Mesalamine delayed-release tablets 4.8 grams/day with Asacol (mesalamine) 2.4 grams/day in patients with mildly to moderately active ulcerative colitis. In these studies, 727 patients were dosed with the Mesalamine delayed-release tablet and 732 patients were dosed with the Asacol 400 mg tablet. (One Mesalamine delayed-release 800 mg tablet cannot be substituted for two Asacol 400 mg tablets [see Clinical Pharmacology ( 12.3 )].) The most common reactions reported in the Mesalamine delayed-release tablets group were headache (4.7 percent), nausea (2.8 percent), nasopharyngitis (2.5 percent), abdominal pain (2.3 percent), exacerbation of ulcerative colitis (2.3 percent), diarrhea (1.7 percent), and dyspepsia (1.7 percent); Table 1 enumerates adverse reactions that occurred in the three studies. The most common reactions in patients with moderately active ulcerative colitis (602 patients dosed with Mesalamine delayed-release tablets and 618 patients dosed with the Asacol 400 mg) were the same as all treated patients. Discontinuations due to adverse reactions occurred in 3.9 percent of patients in the Mesalamine delayed-release tablets group and in 4.2 percent of patients in the Asacol 400 mg tablet comparator group. The most common cause for discontinuation was gastrointestinal symptoms associated with ulcerative colitis. Severe adverse reactions occurred in 7.6 percent of patients in the Mesalamine delayed-release tablets group and in 7.6 percent of patients in the Asacol 400 mg tablet comparator group. Most of these reactions were gastrointestinal symptoms related to ulcerative colitis. Serious adverse reactions occurred in 0.8 percent of patients in the Mesalamine delayed-release tablets group and in 1.8 percent of patients in the Asacol 400 mg tablet comparator group. The majority involved the gastrointestinal system. Table 1.
