Sulfasalazine affects a substance in the body that causes inflammation, tissue damage, and diarrhea.
Sulfasalazine is used to treat moderate to severe ulcerative colitis. It is also used to treat rheumatoid arthritis in children and adults who have received other arthritis medications without successful treatment of symptoms.
Sulfasalazine may also be used for other purposes not listed in this medication guide.
What is the most important information I should know about Azulfidine EN-tabs (Sulfasalazine)?
You should not use this medication if you have porphyria, a blockage in your bladder or intestines, or if you are allergic to sulfasalazine, sulfa drugs, aspirin, or salicylates (such as Disalcid, Doan’s Pills, Dolobid, Salflex, Tricosal, and others).
Before using sulfasalazine, tell your doctor if you have asthma, kidney or liver disease, or glucose-6-phosphate dehydrogenase (G6PD) deficiency.
