Uses

Mesalazine is part of a class of drugs known as aminosalicylates. Aminosalicylates work by reducing inflammation in the lining of the intestines. This is useful for the maintenance treatment of inflammatory bowel disease.

Mesalazine is mainly indicated to treat the following conditions:

  • Ulcerative colitis
  • Crohn’s disease

How should I take mesalazine?

Mesalazine is available as an oral tablet, granules, and rectal suppository. The oral tablet and granules should be taken by mouth without chewing, crushing, or dissolving it in water. Drink a glass of water after swallowing the medication. The tablets should be taken on an empty stomach, one hour before meals.

The rectal suppository should be stored at controlled room temperature or in the refrigerator until it is ready to be used. Laying on your side with one leg bent or standing with one leg on a chair can make it easier to insert the suppository. Insert the suppository with the tapered end first. Straighten your legs and sit or lie still for 15 to 20 minutes to allow the medication to dissolve.

How do I store mesalazine?

This drug should be stored at room temperature (20-25°C) and be protected from light and moisture. Rectal suppositories may be stored in the refrigerator to prevent melting. Do not store it in the freezer.
