Azulfidine treats pain and inflammation caused by rheumatoid arthritis and an intestinal disease called ulcerative colitis. Can cause your skin or urine to turn yellow or orange.
Azulfidine is a prescription medication used to treat the symptoms of ulcerative colitis including bowel inflammation, diarrhea (stool frequency), rectal bleeding, and abdominal pain. Azulfidine EN-tabs (delayed-release tablets) is used to treat rheumatoid arthritis in adults and children when other medications have not worked.
Azulfidine belongs to a group of drugs called aminosalicylates. It works by reducing inflammation (swelling) inside the body.
Azulfidine comes as regular and delayed-release tablets (Azulfidine EN-tabs). It is usually taken four times daily after meals. Drink a full glass of water after taking Azulfidine to protect the kidneys and to prevent kidney stones.
Common side effects include loss of appetite, nausea or vomiting, and headache.

Azulfidine and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
Azulfidine falls into category B. There are no well-done studies that have been done in humans with Azulfidine. In animal studies, pregnant animals were given this medication, and the babies did not show any medical issues related to this medication.
There have been case reports of neural tube defects (NTDs) in infants born to mothers who were exposed to Azulfidine during pregnancy, but the role of Azulfidine in these defects has not been established. However, oral Azulfidine inhibits the absorption and metabolism of folic acid which may interfere with folic acid supplementation and diminish the effect of periconceptional folic acid supplementation that has been shown to decrease the risk of NTDs.
Azulfidine and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
Azulfidine has been detected in human breast milk. Because of the possibility for adverse reactions in nursing infants from Azulfidine, a choice should be made whether to stop nursing or to stop use of this medication. The importance of the drug to the mother should be considered.
