Regulatory Safety Information While Canasa does not have a boxed warning, the FDA-approved labeling includes several important safety precautions that healthcare providers must monitor: Renal Impairment: The FDA requires labeling to include warnings about potential kidney toxicity. Healthcare providers are advised to evaluate renal function prior to starting therapy and periodically during treatment. Mesalamine-Induced Acute Intolerance Syndrome: Regulatory information includes warnings that mesalamine may cause an acute intolerance syndrome that can be difficult to distinguish from a flare of inflammatory bowel disease. Hypersensitivity Reactions: The labeling includes precautions for patients with known hypersensitivity to salicylates or other components of the suppository. Hepatic Failure: There are reports of hepatic failure in patients with pre-existing liver disease who take mesalamine, leading to regulatory requirements for caution in these populations.
