Azulfidine (sulfasalazine) is a longstanding prescription medicine in the United States used to treat inflammatory conditions of the bowel and joints. It is available in two main oral forms: immediate‑release 500 mg tablets and delayed‑release 500 mg tablets, marketed as EN‑tabs (enteric‑coated to help reduce stomach upset). In American clinical practice, sulfasalazine remains a core option for inducing and maintaining remission in ulcerative colitis and for improving symptoms in rheumatoid arthritis, particularly when first‑line therapies are insufficient.

Azulfidine is the original brand name; generic sulfasalazine products are widely available throughout the USA from multiple FDA‑approved manufacturers. Many patients and clinicians choose the enteric‑coated formulation (Azulfidine EN‑tabs) to enhance gastrointestinal tolerability. Your prescriber will determine the most appropriate formulation and dose based on your diagnosis, disease severity, and response to treatment. In the United States, Azulfidine is dispensed by licensed pharmacies upon receipt of a valid prescription.

Azulfidine cost in the USA

Generic sulfasalazine is commonly used in the United States and can offer substantial savings compared with the branded product. Pricing varies based on tablet strength, formulation (immediate‑release vs. delayed‑release), quantity, insurance coverage, and pharmacy location. Many US pharmacies and prescription‑savings programs provide competitive prices on 500 mg tablets.

As a general orientation, per‑tablet costs for generic sulfasalazine often decrease when purchasing larger quantities. Delayed‑release tablets (EN‑tabs) may be priced higher than immediate‑release tablets due to their enteric coating. For the most accurate and up‑to‑date price at your ZIP code, check with your local pharmacy or compare offers online. Your clinician’s prescription will specify the formulation (IR vs. EN‑tabs), dosing schedule, and quantity that fits your treatment plan and budget.

Note: Prices can change frequently and may differ depending on insurance copays, deductibles, or manufacturer coupons. Our partner pharmacy can help you review current options, including cost‑saving strategies such as 90‑day fills or generic substitutions when appropriate.

What is Azulfidine (sulfasalazine)?

Azulfidine is a disease‑modifying anti‑inflammatory drug (DMARD) that contains sulfasalazine, a compound formed from sulfapyridine and 5‑aminosalicylic acid (5‑ASA) linked by an azo bond. In the colon, bacterial enzymes split sulfasalazine into its two components. The 5‑ASA portion acts locally as an anti‑inflammatory agent on the colonic mucosa, while sulfapyridine is systemically absorbed and contributes to the medication’s overall immunomodulatory effect. These mechanisms underpin Azulfidine’s role in inflammatory bowel disease and rheumatologic conditions.

Azulfidine is FDA‑approved for the treatment of ulcerative colitis (for both active disease and maintenance of remission) and for rheumatoid arthritis in adults with inadequate response to NSAIDs. It is also indicated in polyarticular juvenile rheumatoid arthritis (now commonly termed juvenile idiopathic arthritis) for children who do not respond to first‑line therapies. Some clinicians may use sulfasalazine off‑label in select cases of Crohn’s disease with predominant colonic involvement; medical supervision is essential for all uses.

How Azulfidine works

Sulfasalazine’s benefits in ulcerative colitis are largely attributed to the local anti‑inflammatory effects of 5‑ASA on the intestinal mucosa, which can reduce prostaglandin and leukotriene synthesis and modulate cytokine signaling. In rheumatoid arthritis, sulfasalazine acts as a DMARD by dampening inflammatory pathways, including effects on B‑cells, T‑cells, and inflammatory mediators. It may decrease immunoglobulin production and inhibit pro‑inflammatory cytokines, ultimately helping reduce joint pain, swelling, and long‑term structural damage when used as part of a comprehensive treatment plan.

Indications and uses

Azulfidine (sulfasalazine) may be recommended by your clinician for the following FDA‑approved indications:

• Ulcerative colitis – treatment of active disease and maintenance of remission
• Rheumatoid arthritis (adults) – in patients with inadequate response to NSAIDs
• Polyarticular juvenile rheumatoid arthritis – as part of a stepwise approach when NSAIDs are insufficient

Additional clinician‑directed uses may include carefully selected cases of colonic Crohn’s disease or other inflammatory conditions. Your care team will determine suitability, dosing, and duration based on current guidelines and your individual health profile.

Dosage and administration

Your provider will personalize the dose and formulation (immediate‑release vs. EN‑tabs) to minimize side effects and improve adherence. It is common to “start low and go slow,” increasing the dose over 1–2 weeks to enhance tolerability.

Ulcerative colitis (adults)

Active disease (induction): 3 to 4 grams per day in divided doses every 6–8 hours. Many clinicians begin with 500 mg to 1 g daily and increase by 500 mg to 1 g every few days as tolerated until the target daily dose is reached.

Maintenance of remission: 2 grams per day in divided doses. Your exact dose may vary depending on disease activity and your response.

Ulcerative colitis (pediatrics)

Typical dosing is 40–60 mg/kg/day divided every 6–8 hours, not to exceed clinician‑directed maximums. Pediatric dosing and monitoring must be supervised by a pediatric specialist.

Rheumatoid arthritis (adults)

Start with 500 mg daily, then gradually increase (for example, by 500 mg each week) to a usual target of 2 g/day in divided doses (1 g twice daily). Some patients may require up to 3 g/day based on efficacy and tolerability. Clinical benefit often appears within 4–12 weeks; continue therapy as directed and attend routine monitoring visits.

Polyarticular juvenile rheumatoid arthritis

Clinician‑directed dosing typically starts low and is titrated based on weight, response, and tolerability. Pediatric rheumatology supervision is strongly recommended.

Administration tips

• Take with food and a full glass of water to reduce stomach upset.
• Swallow delayed‑release (EN‑tabs) whole; do not crush or chew.
• If a dose is missed, take it when remembered unless it is close to the next dose. Do not double up without clinician advice.
• Hydration is important; maintain adequate fluid intake unless otherwise directed.

Contraindications

Do not take Azulfidine if you have any of the following:

• Hypersensitivity to sulfasalazine, sulfonamides, or salicylates
• Intestinal or urinary tract obstruction
• Porphyria

Discuss your full allergy history and all medical conditions with your clinician before starting therapy.

Warnings and precautions

Sulfasalazine is generally well tolerated when appropriately prescribed, but important risks exist. Work with your provider to monitor and manage safety.

Serious skin reactions

Stop the medication and seek urgent medical care if you experience severe rash, blistering, mucosal sores, fever, or signs of Stevens‑Johnson syndrome/toxic epidermal necrolysis.

Hematologic effects

Azulfidine can rarely cause blood dyscrasias (e.g., agranulocytosis, aplastic anemia, hemolytic anemia). Routine complete blood count (CBC) monitoring is required. Report unexplained fever, sore throat, pallor, or easy bruising immediately.

Hepatic and renal effects

Monitor liver function tests (LFTs) and kidney function at baseline and regularly thereafter. Contact your clinician for jaundice, dark urine, persistent nausea, or abdominal pain.

G6PD deficiency

Use caution in individuals with glucose‑6‑phosphate dehydrogenase deficiency, as hemolysis can occur.

Folate deficiency

Sulfasalazine may reduce folate absorption; supplementation is often recommended (e.g., 1–2 mg daily) during therapy, especially before and during pregnancy.

Photosensitivity

This medicine may increase sun sensitivity. Use sunscreen, protective clothing, and avoid tanning beds.

Fertility

Reversible oligospermia (reduced sperm count) has been reported in males and generally resolves upon discontinuation. Discuss family planning with your clinician if relevant.

Side effects

Not everyone experiences side effects, and many are mild and improve as your body adjusts. Report troublesome or persistent symptoms to your healthcare provider.

Common side effects

• Nausea, dyspepsia, loss of appetite
• Headache, dizziness
• Rash or mild skin reactions
• Orange‑yellow discoloration of urine or skin (harmless)
• Reversible decrease in sperm count in males

Serious side effects (seek medical advice immediately)

• Severe rash, blistering, mouth ulcers
• Unusual bleeding or bruising, signs of infection (fever, sore throat)
• Yellowing of the skin/eyes, dark urine, severe abdominal pain
• Shortness of breath, chest pain, severe fatigue

Laboratory monitoring

Regular monitoring helps ensure safe and effective use:

• CBC with differential and platelets: at baseline; then every 2 weeks for the first 3 months; monthly for the next 3 months; and every 3 months thereafter, or as directed.
• Liver function tests and renal function: baseline and periodically.
• Assess for folate status; supplementation is often advised.

Drug interactions

Always provide a complete list of your medications, vitamins, and supplements to your healthcare provider and pharmacist. Important interactions may include:

• Warfarin: potential enhancement of anticoagulant effect; close INR monitoring.
• Methotrexate: increased risk of bone marrow suppression; vigilant monitoring required.
• Digoxin: reduced absorption; serum levels may need monitoring.
• Folic acid: absorption may be reduced by sulfasalazine; supplemental dosing is typically recommended.
• Iron and antibiotics: may affect absorption and gut flora; spacing doses may help.
• Cyclosporine or isoniazid: monitor for additive toxicity as advised by your clinician.

This is not a complete list of interactions. Do not start, stop, or change any medication without professional guidance.

Pregnancy, breastfeeding, and family planning

Many individuals continue sulfasalazine during pregnancy when benefits outweigh risks; folate supplementation (often 2 mg daily) is typically recommended before conception and throughout pregnancy. Discuss your plans with your obstetrician, gastroenterologist, or rheumatologist. During breastfeeding, small amounts may pass into breast milk and may cause diarrhea or fussiness in infants; your clinician will help weigh risks and benefits and consider monitoring the baby.

Tips from our pharmacists

• Take Azulfidine with meals and plenty of water to reduce stomach upset.
• If you are prescribed EN‑tabs, swallow the tablet whole to preserve the enteric coating.
• Symptom improvement in rheumatoid arthritis may take several weeks; continue as directed and keep follow‑up appointments.
• Orange‑yellow urine or skin is a known, harmless effect of sulfasalazine; however, yellowing of the eyes or skin with dark urine could suggest liver issues—contact your clinician promptly if this occurs.
• Use sun protection; this medicine can increase photosensitivity.

Azulfidine vs. Azulfidine EN‑tabs

Both contain sulfasalazine 500 mg. The key difference is the enteric coating in EN‑tabs, designed to release the drug in the intestine rather than the stomach, which can improve tolerability for some patients. Your prescriber may choose EN‑tabs if you experience gastrointestinal side effects with the immediate‑release tablets. Do not crush or chew EN‑tabs.

Azulfidine vs. mesalamine

Both are anti‑inflammatory agents used in ulcerative colitis. Sulfasalazine delivers 5‑ASA (mesalamine) to the colon but also contains sulfapyridine, which may contribute to systemic side effects. Some patients who cannot tolerate sulfasalazine do well on mesalamine‑only formulations; others respond better to sulfasalazine. Your clinician will consider side effect profiles, cost, formulation preferences, and disease location when selecting therapy.

Frequently asked questions

How long does Azulfidine take to work?

In ulcerative colitis, some improvement may be seen within days to weeks, with continued gains over several weeks. In rheumatoid arthritis, benefits often appear within 4–12 weeks of consistent use.

Can I drink alcohol while taking sulfasalazine?

Alcohol in moderation may be allowed for some individuals, but because sulfasalazine can affect the liver and cause gastrointestinal upset, many clinicians advise limiting or avoiding alcohol. Ask your provider for personalized guidance.

What if I have a sulfa or salicylate allergy?

Do not take Azulfidine if you have a known allergy to sulfonamides (sulfa drugs) or salicylates. Inform your clinician of all drug allergies before starting treatment.

Will I need blood tests?

Yes. Routine CBCs and liver/renal function tests are standard with sulfasalazine. Your clinician will set a schedule and adjust therapy if abnormalities develop.

Can Azulfidine affect fertility?

Reversible reductions in sperm count can occur in males and usually resolve after discontinuation. Discuss family planning with your provider if this is a concern.
