Product Info

The sections below will provide you with more specific information and guidelines related to sulfasalazine and its correct use. Please read them carefully.

FDA Information

Sulfasalazine was approved by the Food and Drug Administration in 1950.

Azulfidine EN-tabs
® is the only formulation of sulfasalazine approved by the FDA for the treatment of both juvenile and adult RA. The enteric-coated formulation of Azulfidine EN-tabs® was specifically designed to reduce the likelihood of nausea and stomach upset.

A prescription is required for this medicine.

Please visit the official site of the FDA for further information.

Why is this medication prescribed?

Sulfasalazine is used to treat a certain type of bowel disease called ulcerative colitis. This medication does not cure this condition, but it helps decrease symptoms such as fever, stomach pain, diarrhea, and rectal bleeding. After an attack is treated, sulfasalazine is also used to increase the amount of time between attacks. This medication works by reducing irritation and swelling in the large intestines.

In addition, delayed-release tablets of sulfasalazine are used to treat rheumatoid arthritis and juvenile rheumatoid arthritis. Sulfasalazine helps to reduce joint pain, swelling, and stiffness. Early treatment of rheumatoid arthritis with sulfasalazine helps to reduce and even prevent further joint damage so you can do more of your normal daily activities. This medication is used together with other drugs, rest, and physical therapy in patients who have not responded to other medications (such as salicylates and nonsteroidal anti-inflammatory drugs [NSAIDs]).

Other uses for this medicine

Sulfasalazine may also be used to treat stomach pain, rectal bleeding, diarrhea caused by Crohn’s disease, and back pains and inflammation (ankylosing spondylitis).

However, it is important that you talk to your doctor about the possible risks of using this drug for your particular condition

Dosage and using this medicine

Sulfasalazine comes as regular and delayed-release (enteric-coated) tablets. It is usually 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 exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.

Each dose should be taken with a full glass of water, and usually after meals.

Do not crush, chew, or break the delayed-release tablets (Azulfidine EN-tabs®). Swallow them whole. They are specially formulated to release the medication after they have passed through your stomach.

Call your doctor if you find an undissolved delayed-release (Azulfidine EN-tabs®) tablet in your stool.

Do not stop taking sulfasalazine, even if you begin to feel better, without first talking to your doctor. It is very important to continue taking sulfasalazine to control your condition.

You may not be able to take sulfasalazine, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.

Sulfasalazine may decrease the absorption of digoxin (Lanoxin®, Lanoxicaps®). Your doctor may want to monitor the digoxin levels in your blood if you are taking this medicine.
