Mesalamine-induced nephrotoxicity should be suspected in patients developing renal dysfunction during treatment. Use of mesalamine 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 mesalamine's main metabolite, Nacetylaminosalicylic acid N-Ac-5-ASA.
