What is Canasa Suppository?

Canasa Suppository (Mesalamine) is a medication which is prescribed to treat ulcerative proctitis, a type of bowel disease. It does not cure this disease but may decrease the number of stools, the amount of mucus or blood in the stools and rectal bleeding. Mesalamine is an anti inflammatory drug which blocks the production of natural chemicals which may cause pain or swelling.

Always read the patient information and instructions carefully before using this medication.

  • This medication is taken rectally. The 1000mg strength medication is typically taken once rectally at bedtime. Canasa 250mg and 500mg is typically taken between one and three times daily. Your Canasa dosage is based on your medical condition and response to treatment. Do not change or increase your dosage unless advised by a doctor.
  • This medication is most effective following a bowel movement.
  • Wash your hands thoroughly before and after using this medication. Unwrap the suppository right before using, trying to handle it as little as possible as it may melt.
  • Lie down on your left side with your right knee bent.
  • Gently insert the suppository, pointed end first, into your rectum with your finger. Use a small amount of lubricating gel on the tip of the suppository if needed.
  • Remain lying down for a few minutes after using.
  • If possible, try to avoid having a bowel movement for between one and three hours after use.

Q: What is a suppository?
