Colitis Home > Canasa Medication Information

Your healthcare provider may prescribe Canasa® (mesalamine) if you have ulcerative proctitis. As a type of aminosalicylate, this medication works by inhibiting the production of certain inflammatory chemicals in the lining of the colon.
This prescription drug comes in the form of a suppository and is inserted rectally; do not take this drug by mouth. Typically, one suppository is inserted at bedtime. Although most people tolerate Canasa well, side effects are possible and can include dizziness, rectal pain, and fever.
Before starting treatment, it's important to review Canasa's safety information. This medication may not be suitable for everyone, so make sure your healthcare provider knows if you have any other medical conditions, such as kidney disease or any allergies, or are taking any other type of medicine, including nonprescription medications, herbal supplements, or vitamins.
