Table of contents:

Salazopyrin EC (generically known as Sulfasalazine) is a prescription medication medication sulfasalazine, which is commonly used to treat inflammatory bowel disease and rheumatoid arthritis. Sulfasalazine helps decrease symptoms such as fever, stomach pain, diarrhea, and rectal bleeding, but does not cure these conditions.

Sulfasalazine works by preventing the production of certain chemicals in the body that cause inflammation, and by helping to reduce irritation and swelling in the large intestines. It is used to treat inflammatory bowel diseases such as ulcerative colitis and Crohn's disease, as well as rheumatoid arthritis and psoriatic arthritis.

Use and Dosage

Salazopyrin EC, also referred to as sulfasalazine, is a tablet that should be taken orally after meals with a full glass of water (8 ounces or 240 milliliters), or as prescribed by your doctor. To avoid stomach irritation, your doctor may gradually increase your dose when beginning treatment. The dosage is determined by your medical condition and your reaction to the medication. In children, the dosage is also based on their weight.

If you are using the delayed-release tablets, you must swallow them whole. Chewing, crushing, or breaking the tablets can increase the chance of stomach irritation. During treatment with the tablet, make sure to drink plenty of fluids, unless instructed otherwise by your doctor, to prevent the formation of kidney stones.

To obtain the maximum advantage from the tablet, take it routinely at the same time each day, and set a reminder if necessary. You should notify your doctor if your condition does not improve or worsens. It may take 1-3 months to notice an improvement in symptoms for the treatment of rheumatoid arthritis.
