Sulfasalazine is a disease-modifying anti-rheumatic drug (DMARD). It dampens down the underlying disease process, rather than simply treating symptoms.

It's used to treat conditions such as rheumatoid arthritis, psoriatic arthritis, reactive arthritis and arthritis associated with bowel inflammation.
It’s usually taken in tablet form. Each tablet contains 500 mg. You may start on a low dose (e.g. 500 mg once daily) and then increased to a higher dose (e.g. 1 g twice daily).
In some patients sulfasalazine can cause nausea (feeling sick), diarrhoea, stomach pain, dizziness, headache and skin rashes. It can sometimes affect your blood or liver.
