Protect mesalamine delayed-release tablets from moisture. 8 grams) for a duration of 6 weeks.
7) ] The most common adverse reactions (≥2%) are headache, nausea, nasopharyngitis, abdominal pain, and worsening of ulcerative colitis. 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 800 mg tablets have been evaluated in 896 patients with ulcerative colitis in controlled studies. 4 grams per day in patients with mildly to moderately active ulcerative colitis. In these studies, 727 patients were dosed with mesalamine delayed-release 800 mg tablets and 732 patients were dosed with mesalamine delayed-release 400 mg tablets.
7%); 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 800 mg and 618 patients dosed with mesalamine delayed-release 400 mg) were the same as all treated patients.
2% of patients in the mesalamine delayed-release 400 mg tablet comparator group. The most common cause for discontinuation was gastrointestinal symptoms associated with ulcerative colitis. 8% of patients in the mesalamine delayed-release tablet comparator group.
The majority involved the gastrointestinal system. Table 1. 2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of mesalamine delayed-release or other mesalamine-containing products or products that are metabolized to mesalamine.
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.
5 WARNINGS AND PRECAUTIONS Renal Impairment : Assess renal function at the beginning to treatment and periodically during treatment. Evaluate the risks and benefits in patients with known renal impairment or taking nephrotoxic drugs; monitor renal function.
Discontinue mesalamine delayed-release if renal function deteriorates. 6) Mesalamine-Induced Acute Intolerance Syndrome : Symptoms may be difficult to distinguish from an ulcerative colitis exacerbation; monitor for worsening symptoms; discontinue if acute intolerance syndrome suspected.
2) Hypersensitivity Reactions, including Myocarditis and Pericarditis : Evaluate patients immediately and discontinue if a hypersensitivity reaction is suspected. 3) Hepatic Failure : Evaluate the risks and benefits in patients with known liver impairment.
4) Severe Cutaneous Adverse Reactions : Discontinue at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation. 5) Photosensitivity : Advise patients with pre-existing skin conditions to avoid sun exposure, wear protective clothing, and use a broad-spectrum sunscreen when outdoors.
6) Nephrolithiasis: Mesalamine-containing stones are undetectable by standard radiography or computed tomography (CT). Ensure adequate hydration during treatment. 7) Iron Content of Mesalamine Delayed-Release : Consider the iron content of mesalamine delayed-release in patients taking iron supplementation and those at risk of iron overload.
8) Interference with Laboratory Tests : Use of mesalamine may lead to spuriously elevated test results when measuring urinary normetanephrine by liquid chromatography with electrochemical detection. 2) ] . 2) ] . Evaluate renal function prior to initiation of mesalamine delayed-release and periodically while on therapy.
Evaluate the risks and benefits of using mesalamine delayed-release in patients with known renal impairment or history of renal disease or taking concomitant nephrotoxic drugs. Discontinue mesalamine delayed-release if renal function deteriorates while on therapy.

6) ] . 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. 3% of mesalamine delayed-release-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. Monitor patients for worsening of these symptoms while on treatment. If acute intolerance syndrome is suspected, promptly discontinue treatment with mesalamine delayed-release.
3 Hypersensitivity Reactions Hypersensitivity reactions have been reported in patients taking sulfasalazine. Some patients may have a similar reaction to mesalamine delayed-release tablets or to other compounds that contain or are converted to mesalamine.
As with sulfasalazine, mesalamine-induced hypersensitivity reactions may present as internal organ involvement, including myocarditis, pericarditis, nephritis, hepatitis, pneumonitis, and hematologic abnormalities. Evaluate patients immediately if signs or symptoms of a hypersensitivity reaction are present.
Discontinue mesalamine delayed-release if an alternative etiology for the signs or symptoms cannot be established. 4 Hepatic Failure There have been reports of hepatic failure in patients with pre-existing liver disease who have been administered mesalamine.
Evaluate the risks and benefits of using mesalamine delayed-release in patients with known liver impairment. 2)] . Discontinue mesalamine delayed-release at the first appearance of signs or symptoms of severe cutaneous adverse reactions, or other signs of hypersensitivity and consider further evaluation.
6 Photosensitivity Patients treated with mesalamine or sulfasalazine who have pre-existing skin conditions such as atopic dermatitis and atopic eczema have reported more severe photosensitivity reactions. Advise patients to avoid sun exposure, wear protective clothing, and use a broad-spectrum sunscreen when outdoors.
7 Nephrolithiasis Cases of nephrolithiasis have been reported with the use of mesalamine, including stones of 100% mesalamine content. Mesalamine-containing stones are radiotransparent and undetectable by standard radiography or computed tomography (CT).
Ensure adequate fluid intake during treatment with mesalamine delayed-release. 8 Iron Content of Mesalamine Delayed-Release Mesalamine delayed-release contains iron oxide as a colorant in the coating of the delayed-release tablets. 72 mg of iron.
2) ] . Before prescribing mesalamine delayed-release to patients receiving iron supplementation or those at risk for developing iron overload, consider the combined daily amount of iron from all sources, including mesalamine delayed-release.
9 Interference with Laboratory Tests Use of mesalamine delayed-release may lead to spuriously elevated test results when measuring urinary normetanephrine by liquid chromatography with electrochemical detection because of the similarity in the chromatograms of normetanephrine and the main metabolite of mesalamine, N-acetyl-5-aminosalicylic acid (N-Ac-5-ASA).
Consider an alternative, selective assay for normetanephrine.
