Canasa Rectal Suppositories

Canasa® (mesalamine) is a prescription drug used for the treatment of ulcerative proctitis, which is a type of inflammatory bowel disease. Because it is a rectal suppository, Canasa should never be taken by mouth -- it is inserted into the rectum once a day, usually at bedtime. Most people have no problems when using this drug, although side effects are possible.
 
When using the rectal suppositories, keep in mind that the product will stain several surfaces, including fabrics, vinyl, and painted surfaces, so you need to handle it carefully. Also, you should avoid having a bowel movement for one to three hours after inserting the medication. This helps ensure the effectiveness of each dose.
