Precautions and Warnings when Taking Pentasa 

Do not take this anti-inflammatory drug if you have an allergy to mesalamine, other salicylates or aminosalicylates, and any inactive ingredients each tablet contains. Signs of serious allergic reactions are severe dizziness, skin rashes, swelling of the face and neck, hives, swollen lymph nodes, and trouble breathing. This must be considered a medical emergency. Immediately call for emergency help if this happens. 

This oral drug may be contraindicated for people with a history of pyloric stenosis or any stomach blockage, liver disease, and kidney disease. Due to possible drug interactions, it is also essential to talk about all the prescription drugs, OTC drugs, supplements, and herbal products you are taking. 

This medication contains an active ingredient that is similar to aspirin. Patients eighteen years of age and below should not administer aspirin and any aspirin-related products if suffering from flu, chickenpox, or any undiagnosed illness.
