Consumer Information

Information about the product including what the product is used for, dosage, warnings, proper use and side effects. This summary will not tell you everything about the product. Contact your healthcare professional if you have any questions about the product.


What the medication is used for

pms-SULFASALAZINE and pms-SULFASALAZINE-E.C. contain sulfasalazine, which are anti-inflammatory drugs indicated as an adjunctive therapy in the treatment of severe ulcerative colitis (bowel inflammation), proctitis (inflammation of the rectum) or distal ulcerative colitis and Crohn’s disease.

pms-SULFASALAZINE-E.C. contains sulfasalazine in delayedrelease tablets, indicated for the treatment of active rheumatoid arthritis, when treatment with an adequate conventional first line therapy has failed.

What it does

The way in which pms-SULFASALAZINE and pms-SULFASALAZINE work is unclear and thought to involve three actions:

  • anti-inflammatory action, which blocks the production and effect of certain substances in the body (cyclooxygenase, prostaglandins and others), which are involved in producing inflammation;
  • bacteriostatic (anti-bacterial) action, which preventsthe growth of several kinds of bacteria which are possibly involved in inflammation;
  • immunosuppressive action (which reduces a patient’s overly active immune response, which has been linked to inflammatory diseases).

All of these actions likely work together to reduce symptoms of gut inflammation, diarrhea, swelling and bleeding.

When it should not be used

Do not use pms-SULFASALAZINE or pms-SULFASALAZINE-E.C. if you have:

  • a hypersensitivity (allergic reactions) to sulfasalazine, its metabolites, sulfonamides, salicylates or any other component of this product (see What the non- medicinal ingredients are);
  • an intestinal or urinary obstruction;
  • porphyria (disease of pigment production in tissues).
  • experienced sudden asthmatic attacks, urticaria, rhinitis, or other allergic-type reactions to acetylsalicylic acid or other nonsteroidal anti-inflammatory, as these attacks are serious and can be fatal (see WARNINGS AND PRECAUTIONS for a complete list of conditions where pms-SULFASALAZINE and pms-SULFASALAZINE E.C. should not be used);
  • severe kidney (renal) impairment and/or severe liver (hepatic) impairment (see Side Effects and What to Do About Them)
