What is Sulfazine?
Sulfazine affects a substance in the body that causes inflammation, tissue damage, and diarrhea.
Sulfazine is used to treat moderate to severe ulcerative colitis.
Sulfazine is also used to treat rheumatoid arthritis in children and adults who have used other arthritis medicines without successful treatment of symptoms.
Sulfazine may also be used for purposes not listed in this medication guide.
Before taking this medicine
You should not use Sulfazine if you are allergic to it, or if you have:
a blockage in your bladder or intestines;
porphyria (a genetic enzyme disorder that causes symptoms affecting the skin or nervous system);
if you are allergic to sulfa drugs (such as Bactrim, SMX-TMP, SMZ-TMP, and others); or
To make sure Sulfazine is safe for you, tell your doctor if you have:
kidney disease, or a history of kidney stones;
a genetic enzyme deficiency called glucose-6-phosphate dehydrogenase (G6PD) deficiency;
a blood cell disorder;
weak immune system (caused by disease or by using certain medicine);

FDA pregnancy category B. Sulfazine is not expected to harm an unborn baby. However, you may need to take folic acid supplements if you take this medicine during pregnancy. Follow your doctor's instructions. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
Sulfasalazine can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Sulfazine should not be given to a child younger than 2 years old.
How should I take Sulfazine?
Follow all directions on your prescription label. Do not take Sulfazine in larger or smaller amounts or for longer than recommended.
Sulfazine can weaken your immune system. Your blood may need to be tested often.
This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using Sulfazine.
Take this medicine after a meal.
Do not crush, chew, or break an enteric coated pill. Swallow it whole. The pill has a special coating to protect your stomach. Breaking the pill will damage this coating.
For best results, keep using this medicine as directed. Sulfazine 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 medicines until your doctor tells you to. Your symptoms may not improve right away when you start taking Sulfazine, and you may still need your other medicines for awhile.

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
