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
Sulfasalazine reduces inflammation, but
the exact way this happens is not known. It has been used to decrease bowel
inflammation in inflammatory bowel disease and joint
inflammation in rheumatoid arthritis. More recently, it has been used to fight
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.
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.
Sulfasalazine may help control pain
and inflammation for some people in areas other than the spine. Its
effectiveness is still being studied.footnote 1

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
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.
