About This Medication
Pfizer Patient Assistance Program Patient Guide: How to Get Azulfidine EN (sulfasalazine) at Low or No Cost
Azulfidine EN (sulfasalazine) is a prescription medication used to treat inflammatory conditions like ulcerative colitis, rheumatoid arthritis, and Crohn's disease. The Pfizer Patient Assistance Program offers this medicine at no cost to eligible patients who meet income and insurance criteria, helping those facing financial hardship access essential treatment.[1][4]
About Azulfidine EN (sulfasalazine)
Azulfidine EN is an enteric-coated tablet form of sulfasalazine, designed to release the drug in the intestines to reduce stomach upset. It works by reducing inflammation in the bowels and joints. Common uses include:
- Managing ulcerative colitis (active and remission phases)
- Treating rheumatoid arthritis in adults and children
- Helping with Crohn's disease symptoms
Doctors prescribe it when other treatments aren't suitable. Always take as directed, with food or milk, and report side effects like nausea, headache, or rash to your healthcare provider. This program provides free medication but does not cover doctor visits or lab tests.[4][9]
Who Qualifies for the Program?
The Pfizer Patient Assistance Program is for US residents (no citizenship proof needed, but a US address is required) aged 18+ with a valid US prescription for outpatient use. Key requirements include:
- Financial need: Low household income (often up to 500% of the Federal Poverty Level, or FPL, though exact thresholds vary—check Pfizer RxPathways for your situation)
- Insurance status: Uninsured, underinsured, or government-insured (like Medicare) but unable to afford costs. Commercially insured patients are not eligible.[4][9]
- Diagnosis: FDA-approved condition with proof via prescription
- No other restrictions on household size, but income is assessed for the entire household
Medicare patients may qualify through specific pathways if enrolled in the Medicare Prescription Payment Plan and not yet at their out-of-pocket maximum.[7][9]
Income Eligibility Breakdown
Eligibility hinges on pre-tax household income, typically not exceeding 500% of the FPL. Use the Pfizer RxPathways Program Finder for personalized limits, as they adjust yearly. Here's a sample table based on 2026 FPL guidelines (verify current levels):
| Household Size | 100% FPL | 400% FPL | 500% FPL (Typical Max) |
|---|---|---|---|
| 1 | $15,060 | $60,240 | $75,300 |
| 2 | $20,440 | $81,760 | $102,200 |
