General Advice
Because the tablets are coloured yellow they may cause your urine or motions to become a yellow/orange colour. This is normal and harmless but can stain fabric. Any Salazopyrin soiled fabric should be put in to soak. Difficult stains may be removed with a solution of washing soda.
Always test the effect of soda on a small piece of the fabric first. Then apply a mild acid such as white vinegar.
Sulfasalazine has caused permanent staining of extended wear soft contact lenses. Although this happened very rarely. Daily-wear soft contact lenses and gas permeable lenses respond to standard cleaning if this happens.

1. What Salazopyrin EN are and what they are used for
The active substance in Salazopyrin EN is sulfasalazine which is an anti-inflammatory drug and belongs to a group of medicines called aminosalicylates.
Your doctor may give you Salazopyrin EN to treat and manage inflammatory bowel disease or to treat rheumatoid arthritis.
Inflammatory bowel disease
The main forms of inflammatory bowel disease are Ulcerative Colitis and Crohn's disease.
Although the diseases have some features in common, there are some important differences.
Ulcerative Colitis is an inflammatory disease which affects only the large bowel (colon and back passage). The lining of the bowel becomes inflamed (red and swollen) and symptoms include abdominal pain and diarrhoea (which may contain blood and mucus). Salazopyrin EN are used to control the flare-ups of ulcerative colitis. They may also be used at lower doses to prevent more flare-ups of ulcerative colitis.
Crohn's disease is an inflammatory disease which may affect any part of the digestive system from the mouth to the anus, but it most commonly affects the last part of the small bowel and the first part of the large bowel. Symptoms include abdominal pain and diarrhoea (which may be bloody).
Salazopyrin EN are used to control the flare-ups of Crohn's Disease.
Rheumatoid arthritis
Salazopyrin EN are usually given when a group of medicines known as non-steroidal anti-inflammatory drugs (NSAIDs e.g. aspirin and ibuprofen) are not working. They help prevent damage to your joints and work slowly to reduce swelling and stiffness in your joints.
2. Before you take Salazopyrin EN

During the second three months, the same tests should be done once monthly and thereafter once every three months, and as clinically indicated. Urine analysis and an assessment of kidney function should also be done periodically during treatment with Salazopyrin. Thereafter, monitoring will be performed as your doctor requires.
