  • Rectal suspension: hypersensitivity to salicylates, aminosalicylates or to any ingredients in the suppository vehicle
  • Children with chickenpox or flulike symptoms

Effects of Drug Abuse

  • No information available

Short-Term Effects

  • See "What Are Side Effects Associated with Using Mesalamine?"

Long-Term Effects

  • See "What Are Side Effects Associated with Using Mesalamine?"

Cautions

  • Sulfasalazine hypersensitivity, renal insufficiency, coagulation abnormalities, pyloric stenosis
  • Use caution in active peptic ulcer disease, severe renal failure
  • Do not use with lactulose or drugs that lower intestinal pH
  • Although pericarditis rarely occurs, investigate any chest pain or shortness of breath
  • Low concentration of sperm has been reported in males
  • Liver failure may occur, particularly with preexisting liver impairment
  • May lead to falsely elevated test results when measuring urinary normetanephrine by liquid chromatography with electrochemical detection, because of the similarity in the chromatograms of normetanephrine and mesalamine's main metabolite, N-acetyl aminosalicylic acid; an alternative, selective assay for normetanephrine should be considered
  • Worsening of colitis or inflammatory bowel disease may occur following initiation of therapy
  • Renal impairment, including minimal change nephropathy, acute and chronic interstitial nephritis, and renal failure, reported; evaluate renal function prior to initiation of therapy and periodically while on therapy
  • Evaluate the risks and benefits in patients with known renal impairment or taking nephrotoxic drugs; monitor renal function
  • Acute intolerance syndrome may occur; symptoms may be difficult to distinguish from an ulcerative colitis exacerbation; monitor for worsening symptoms; discontinue if acute intolerance syndrome suspected
  • Hypersensitivity reactions, including myocarditis and pericarditis reported; evaluate patients immediately and discontinue if hypersensitivity reaction suspected
  • Evaluate the risks and benefits in patients with known liver impairment
