# Sulfasalazine 500 mg ## Short Description Sulfasalazine 500 mg is a **prescription medicine** used to reduce inflammation in conditions affecting the intestines and joints. It is commonly used for **ulcerative colitis, Crohn's disease in selected cases, rheumatoid arthritis and other inflammatory joint conditions**. Sulfasalazine is often used as a long-term treatment to control inflammation and maintain remission rather than provide immediate pain relief. ## Key Benefits * Helps reduce inflammation in the bowel and joints * Helps control symptoms of ulcerative colitis * May help maintain remission in inflammatory bowel disease * Helps reduce pain, swelling and stiffness associated with inflammatory arthritis * May reduce the need for other anti-inflammatory medicines in some patients * Can be used as a long-term disease-modifying treatment under medical supervision ## Uses / Indications Sulfasalazine 500 mg may be prescribed for: * **Ulcerative colitis** * Certain cases of Crohn's disease * Rheumatoid arthritis * Juvenile idiopathic arthritis * Other inflammatory joint conditions where specifically recommended by a doctor The approved indications may vary by country and formulation. ## How It Works Sulfasalazine is converted in the intestine into two components, **sulfapyridine and 5-aminosalicylic acid (5-ASA/mesalazine)**. The 5-ASA component has local anti-inflammatory effects in the bowel, while sulfapyridine contributes significantly to the systemic effects used in inflammatory joint diseases. The exact mechanism of sulfasalazine in rheumatoid arthritis is not completely understood. ## Dosage & Administration * Take Sulfasalazine 500 mg exactly as prescribed * The dose depends on the condition being treated and your response to treatment * Treatment is often started at a lower dose and gradually increased to reduce stomach-related side effects * Take tablets with plenty of water * Enteric-coated or delayed-release tablets should generally be swallowed whole * Do not crush or chew modified-release or enteric-coated tablets unless specifically instructed * Taking the medicine after food may help reduce stomach discomfort * Drink adequate fluids during treatment unless your doctor has advised fluid restriction * If you miss a dose, take it when remembered unless it is nearly time for the next dose * Do not take a double dose to compensate for a missed dose * Do not stop long-term treatment without discussing it with your doctor Regular blood tests may be recommended to monitor blood counts, liver function and kidney function. ## Side Effects Common side effects may include: * Nausea * Vomiting * Stomach pain or discomfort * Indigestion * Diarrhea * Headache * Dizziness * Loss of appetite * Skin rash * Temporary orange-yellow discoloration of urine or other body fluids Seek urgent medical attention if you develop: * Severe skin rash, blistering or peeling * Fever with sore throat or signs of infection * Unusual bruising or bleeding * Yellowing of the skin or eyes * Severe weakness * Difficulty breathing or facial swelling * Severe abdominal pain * Significant reduction in urine output ## Precautions & Warnings * Tell your doctor if you are allergic to **sulfonamides or salicylates**, including aspirin * Inform your doctor if you have kidney or liver disease * Blood tests may be required before and during treatment * Tell your doctor if you have a history of blood disorders * Sulfasalazine can rarely cause serious blood, liver or kidney problems * Drink sufficient fluids unless medically restricted * Sulfasalazine may cause urine, sweat or tears to become yellow-orange * Contact your doctor if you develop fever, sore throat, unusual bruising or persistent infection symptoms * Tell your doctor if you have asthma or other significant allergies * Inform your doctor if you are pregnant, planning pregnancy or breastfeeding * Keep out of reach of children ## Drug Interactions Sulfasalazine can interact with certain medicines, including: * **Methotrexate** — may increase certain adverse effects and requires medical monitoring * **Folic acid** — sulfasalazine may interfere with folate absorption or metabolism * **Digoxin** — sulfasalazine may reduce digoxin absorption in some patients * **Warfarin and other medicines affecting blood clotting** — monitoring may be required * **Azathioprine or mercaptopurine** — may increase the risk of blood-related adverse effects * Other medicines that can affect the kidneys or liver may require additional monitoring Tell your doctor or pharmacist about all prescription medicines, OTC medicines, vitamins and herbal supplements you use. ## Storage Information * Store according to the manufacturer's instructions * Keep tablets in their original packaging * Protect from excessive heat, moisture and direct sunlight * Keep the container tightly closed * Store at the temperature specified on the product label * Keep out of reach and sight of children * Do not use after the expiry date * Follow the storage instructions printed on the packaging ## Prescription Status Sulfasalazine 500 mg is generally a **prescription-only medicine**.

No. Sulfasalazine is **not a corticosteroid**. It is an anti-inflammatory disease-modifying medicine. ### How does Sulfasalazine work? Sulfasalazine is broken down in the intestine into sulfapyridine and 5-aminosalicylic acid.

This is usually harmless, although unusual or severe symptoms should be discussed with a doctor. ### Does Sulfasalazine affect blood tests? It can. Sulfasalazine may rarely affect blood cells and liver function. Doctors may therefore recommend regular blood counts and liver and kidney tests. ### Can Sulfasalazine cause low blood counts?
