What is the most important information I should know about sulfasalazine oral (Azulfidine EN-Tabs)?

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.

Also tell your doctor about all other medications you use, especially digoxin (digitalis, Lanoxin), folic acid (Folicin, FA-8), or vitamin or mineral supplements that contain folic acid.

Do not crush, break, or chew a sulfasalazine tablet. Swallow the pill whole. The enteric-coated tablet has a special coating to protect your stomach. Breaking the pill could damage this coating.

For best results, keep using the medication as directed. Sulfasalazine will not cure ulcerative colitis, but it can reduce the number of attacks you have.

If you are treating arthritis, do not stop using any of your other arthritis medications until your doctor tells you to.
