What is Azulfidine?

Return to top

Azulfidine, an anti-inflammatory medicine, is prescribed for the treatment of mild to moderate ulcerative colitis and as an added treatment in severe ulcerative colitis. This medication is also prescribed to decrease severe attacks of ulcerative colitis.

Azulfidine EN-tabs are prescribed for people with ulcerative colitis who cannot take the regular Azulfidine tablet because of symptoms of stomach and intestinal irritation such as nausea and vomiting when taking the first few doses of the drug, or for those in whom a reduction in dosage does not lessen the stomach or intestinal side effects. The EN-tabs are also prescribed for adults and children with rheumatoid arthritis who fail to get relief from salicylates (such as aspirin) or other nonsteroidal anti-inflammatory drugs (such as ibuprofen).

The information below is based on the dosage guidelines your doctor uses. Depending on your condition and medical history, your doctor may prescribe a different regimen. Do not change the dosage or stop taking your medication without your doctor's approval.

Rheumatoid Arthritis

Adults: The usual dose of Azulfidine EN-tabs is 2 grams (g) a day, divided into smaller doses. Your doctor may have you start with a lower dose, then raise the dosage to 3 g after 12 weeks.

Children: The typical recommended daily dosage is 30 to 50 mg per 2.2 pounds of body weight, up to a maximum of 2 g, taken in 2 equally divided doses. To reduce the chance of digestive side effects and other reactions, the doctor will probably start with a fraction of the typical dose and build up to it over a period of weeks.

Ulcerative Colitis

Adults: The usual recommended initial dose of Azulfidine and Azulfidine EN-tabs is 3 to 4 g daily divided into smaller doses (intervals between nighttime doses should not exceed 8 hours). In some cases the initial dosage is set at 1 to 2 g daily to lessen side effects. As therapy continues, the dose is usually reduced to 2 g daily.

Children: The usual recommended initial dose is 40 to 60 milligrams (mg) per 2.2 pounds of body weight in each 24-hour period, divided into 3 to 6 doses. For the longer term, the dose is usually reduced to 30 mg per 2.2 pounds of body weight in each 24-hour period, divided into 4 doses.
