Canasa is different than Aspirin (a NSAID), so I doubt you'd have the same reaction. Canasa is a 5-ASA or mesalamine.
Compounds of 5-aminosalicyclic acid (5-ASA) are also called mesalamine. They are chemical cousins to aspirin (acetylsalicylic acid or ASA) but differ in their effects on UC. Aspirin is not effective in treating ulcerative colitis and may actually worsen or trigger an attack. However, 5-ASA compounds can be very effective at treating attacks of UC as well as maintaining remission as long as these drugs reach the portion of the colon or rectum that is inflamed.
As they're chemically different enough, the reaction is not the same. If you have any concerns about
5-ASA due to your prior reactions to Aspirin, then just start with low doses. And Canasa is usually considered a low dose.
