Sulfasalazine is sometimes used for spondylitis, particularly when peripheral joints (joints outside the spine) are involved. It's worth noting that it is not officially approved for spondylitis, so doctors prescribe it "off-label" — meaning it's being used for a condition beyond its original approval, but evidence supports its use.
For spinal symptoms specifically, sulfasalazine is generally not considered effective. It tends to work better for peripheral joint inflammation. When it comes to long-term use, there are some important things to keep in mind:
- Common side effects include headache, nausea, indigestion, vomiting, and reversible male infertility
- Allergy risk — sulfasalazine is a sulfa-based antibiotic, and some people are allergic to sulfa drugs
- It is being prescribed less frequently now that newer, more targeted treatments like biologics are available
With newer DMARDs (like TNF inhibitors and IL-17 inhibitors) showing strong results, sulfasalazine is typically considered when biologics aren't appropriate or accessible.
Always work closely with your rheumatologist to weigh the benefits against the risks for your specific situation, and make sure any long-term use is monitored regularly.
