Sulfasalazine for Ankylosing Spondylitis
Sulfasalazine is a medicine made from salicylic acid—the same active ingredient found in aspirin—plus an antibiotic called sulfapyridine. The medicine comes in time-release tablets taken by mouth.
How It Works
Sulfasalazine reduces inflammation, but the exact way this happens is not known. It has been used to decrease bowel inflammation in inflammatory bowel diseases such as Crohn's and joint inflammation in rheumatoid arthritis. More recently, it has been used to fight inflammation in ankylosing spondylitis, but it does not seem to work on the spine. It is more effective if ankylosing spondylitis is causing symptoms in other areas such as the shoulders and the heels.
Why It Is Used
Ankylosing spondylitis causes pain, stiffness, and swelling of the spine and sometimes other areas such as the hips, chest wall, and heels. Many people who have ankylosing spondylitis also have inflammatory bowel disease. Sulfasalazine helps by decreasing bowel inflammation and abdominal (belly) pain.
How Well It Works
Sulfasalazine may help control pain and inflammation for some people in areas other than the spine. Its effectiveness is still being studied.1

Advice for women
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
