Warnings and Precautions when using Canasa  

Do not use this prescription drug if you have a known allergy to mesalamine, aminosalicylates, salicylates, sulfasalazine, or any inactive ingredients the tablet may contain. Always be watchful for any signs of serious allergic reactions, including trouble breathing, swelling of the face and neck, severe dizziness, swollen lymph nodes, hives/itchiness, and skin rashes. If this occurs, stop using this suppository and seek emergency medical help immediately.

This medication may be contraindicated for people with a history of pericarditis, pancreatitis, kidney problems, and liver disease. Also, due to possible drug interactions, you should discuss all supplements, herbal products, and medications (prescription or nonprescription medications) you are taking.

Mesalamine can make you more sensitive to sun exposure, especially if you have skin conditions like atopic dermatitis and eczema. Limit your exposure to sunlight and avoid indoor tanning. When going outdoors, you must apply sunscreen and wear protective clothing.

Those patients below the age of 18 should not take this medication or other aspirin-like drugs if they have acquired flu, chickenpox, or any undiagnosed illness. Doing this can increase the risk of a rare but serious condition called Reye’s syndrome.

There are still no conclusive studies on Canasa and pregnancy. Pregnant moms must use this medication only if extremely necessary. You should discuss all possible risks with your healthcare provider. For breastfeeding moms, avoid using this drug as it can pass into breastmilk and have undesirable effects on nursing infants.
