Brand Name(s):

  • Azulfidine®EN-tabs®

WHY is this medicine prescribed?

Sulfasalazine is used to treat bowel inflammation, diarrhea (stool frequency), rectal bleeding, and abdominal pain in patients with ulcerative colitis, a condition in which the bowel is inflamed. Sulfasalazine delayed-release (Azulfidine EN-tabs) is also used to treat rheumatoid arthritis in adults and children whose disease has not responded well to other medications. Sulfasalazine is in a class of medications called anti-inflammatory drugs. It works by reducing inflammation (swelling) inside the body.

HOW should this medicine be used?

Sulfasalazine comes as regular and delayed-release (releases the medication in the intestine to prevent irritation to the stomach and to allow the medication to work in the intestine where its effects are needed) tablets. It usually is taken four times a day in evenly spaced doses throughout the day so that no more than 8 hours separates any two doses, if possible. Take sulfasalazine after a meal or with a light snack, then drink a full glass of water. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sulfasalazine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow tablets whole; do not crush or chew them.

Drink plenty of fluids (at least six to eight glasses of water or other beverage per day) while taking sulfasalazine.

Continue to take sulfasalazine even if you feel well. Do not stop taking sulfasalazine without talking to your doctor.

Are there OTHER USES for this medicine?

Sulfasalazine is also used to treat bowel inflammation, diarrhea (stool frequency), rectal bleeding, and abdominal pain in Crohn's disease. Talk to your doctor about the possible risks of using this drug for your condition.

What SPECIAL PRECAUTIONS should I follow?

Before taking sulfasalazine,

  • tell your doctor if you are allergic to sulfasalazine, sulfapyridine, aspirin, choline magnesium trisalicylate (Triosal, Trilisate), choline salicylate (Arthropan), mesalamine (Asacol, Pentasa, Rowasa), salsalate (Argesic-SA, Disalcid, Salgesic, others), sulfa drugs, trisalicylate (Tricosal, Trilisate),or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially digoxin (Lanoxin), folic acid, and vitamins.
  • tell your doctor if you have or have ever had asthma, kidney or liver disease, porphyria, blood problems, or blockage in your intestine or urinary tract.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking sulfasalazine, call your doctor.
  • plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Sulfasalazine may make your skin sensitive to sunlight.

What should I do IF I FORGET to take a dose?

Take the missed dose as soon as you remember it. However, if it is almost time for your next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
