Sulfasalazine
Also known as: Salazopyrin
Sulfasalazine is a well-established DMARD. It has been used in rheumatology for decades and can help many patients with inflammatory arthritis feel and function better.
Calm, careful medication review by a consultant rheumatologist.
What this medicine is
Sulfasalazine is a tablet that modifies immune activity in the joints and gut. It is often started at a low dose and built up gradually to reduce side effects.
Uses and context
It is used in rheumatoid arthritis, psoriatic arthritis, and some forms of spondyloarthritis. It can be used alone or with other DMARDs.
How this relates to rheumatology care
In clinic I introduce sulfasalazine slowly, check baseline blood tests, and monitor blood counts and liver function regularly. Some patients notice a temporary orange tint to urine or tears; this is not harmful.
What safety checks may matter
Baseline full blood count and liver function
Regular blood monitoring, especially in the first few months
Ask about sulfa allergy or aspirin allergy before starting
Adequate folic acid if advised
Side effects and red flags
If you have emergency symptoms such as severe allergic reaction, breathing difficulty, chest pain, stroke-like symptoms, severe abdominal pain, vomiting blood, black stools, sudden vision loss, severe infection symptoms, or severe weakness or confusion, please seek urgent medical care first rather than waiting for a WhatsApp reply.
Severe skin rash, blistering or peeling
Unexplained bruising, bleeding or high fever
Yellowing of the skin or eyes
Severe sore throat or mouth ulcers
Signs of severe allergic reaction
Things worth knowing day to day
Do not take if you have a known sulfa allergy without discussing with me.
Alcohol should be kept low or avoided during treatment.
Discuss any planned pregnancy; sulfasalazine may be continued under review.
Do not stop suddenly without medical advice.
