Sulfasalazine is used to treat a certain type of bowel disease called ulcerative colitis. This medication does not cure this condition, but it helps decrease symptoms such as fever, stomach pain, diarrhea, and rectal bleeding. After an attack is treated, sulfasalazine is also used to increase the amount of time between attacks. This medication works by reducing irritation and swelling in the large intestines.
In addition, delayed-release tablets of sulfasalazine are used to treat rheumatoid arthritis. Sulfasalazine helps to reduce joint pain, swelling, and stiffness. Early treatment of rheumatoid arthritis with sulfasalazine helps to reduce/prevent further joint damage so you can do more of your normal daily activities. This medication is used with other drugs, rest, and physical therapy in patients who have not responded to other medications (salicylates, nonsteroidal anti-inflammatory drugs-NSAIDs).
How to use Azulfidine
Take this medication by mouth after meals with a full glass of water (8 ounces or 240 milliliters) or as directed by your doctor. To prevent stomach upset, your doctor may recommend a slow increase in your dosage when starting treatment. Dosage is based on your medical condition and response to therapy. In children, dosage is also based on weight.
If you are taking the delayed-release tablets, swallow them whole. Do not crush, chew, or break the tablets. Doing so may increase the chance of stomach upset.
Drink plenty of fluids during treatment with this medication unless otherwise directed by your doctor. This will help prevent kidney stones.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.
Inform your doctor if your condition does not improve or if it worsens. For the treatment of rheumatoid arthritis, it may take 1-3 months before you notice any improvement in your symptoms.
Rarely, delayed-release tablets of sulfasalazine may appear whole or only partly dissolved in your stool. If this occurs, tell your doctor right away so your treatment can be changed.
