What is Pentasa?

Pentasa is a medication used to treat the bowel diseases ulcerative colitis and Crohn disease and to prevent their symptoms from recurring. Pentasa contains mesalamine which works by decreasing the swelling within the colon. Taking mesalamine may help to reduce symptoms including stomach pain, rectal bleeding and diarrhea.

Always read the patient information and instructions carefully before using this medication. Follow your doctor’s directions.

  • Pentasa may be taken with or without food.
  • Swallow mesalamine capsules whole without chewing, crushing or breaking them. If you struggle to swallow this medication whole, you may open the capsule and sprinkle the contents onto yoghurt or applesauce and eaten immediately without chewing.
  • Speak to your doctor if your symptoms do not improve.

Cautions

Make sure to tell your doctor and pharmacist:

  • If you have any drug or other allergies.
  • Which other prescription and non-prescription medications you currently take.
  • Your medical history especially of heart disease, kidney disease, liver disease, stomach blockage, intestinal blockage or pyloric stenosis.
  • If you are pregnant, planning on pregnancy or breast feeding.

Also be aware that:

  • Pentasa may cause unusual test results. Tell any medical testing personnel that you are taking mesalamine.

What a lifesaver the Canadian Pharmaceutical Depot is. My prescriptions cost me half of what I would pay in the United States. The product is as described and works as prescribed. The package was intact. Your customer service people have been amazing and answered all the questions I had. Thank you again for being available.

Great communication with the pharmacy. Medication is correct and effective. Excellent price, it’s 1/3 of the cost of using my insurance. So glad my cardiologist gave me the info on Canada Pharmacy Depot.
