• pregnant or breastfeeding patients
• children younger than age 18 (safety and efficacy not established).
• Give Apriso capsules with or without food. Don't give concurrently with antacids.

CV: chest pain, mesalamine-induced cardiac hypersensitivity reactions (myocarditis and pericarditis)
EENT: rhinitis, pharyngitis
GI: nausea, vomiting, diarrhea, eructation, flatulence, anal irritation (with rectal use), pancreatitis
GU: interstitial nephritis, renal failure
Musculoskeletal: back pain
Skin: alopecia, rash
Other: fever, acute intolerance syndrome, anaphylaxis, acute intolerance syndrome
Drug-drug. Antacids: increased risk of dissolution of coating of Apriso granules
Azathioprine, 6-mercaptopurine: increased potential for blood disorders
Nephrotoxic drugs (including nonsteroidal anti-inflammatory agents): increased risk of renal adverse reactions
☞ Monitor carefully for mesalamine-induced cardiac hypersensitivity reactions (myocarditis and pericarditis).
☞ Closely monitor patients with history of allergic reactions to sulfasalazine or sulfite sensitivity (if using enema).
• Assess kidney and liver function before and periodically during therapy.
• Monitor for suppository efficacy, which should appear in 3 to 21 days. However, know that treatment usually continues for 3 to 6 weeks.
☞ Watch for signs and symptoms of intolerance syndrome, such as cramping, acute abdominal pain, bloody diarrhea, fever, headache, and rash. If these occur, discontinue drug and notify prescriber.

• Tell patient to contact prescriber if partially intact tablets repeatedly appear in stools.
