About This Medication

# Arbor Pharmaceuticals Patient Assistance Program Patient Guide: How to Get BiDil at Low or No Cost BiDil (isosorbide dinitrate/hydralazine hydrochloride) is a prescription medication approved to treat **heart failure** in **self-identified Black patients** on standard therapy, usually when symptoms persist. This patient-friendly guide explains the **Arbor Pharmaceuticals Patient Assistance Program (PAP)**, which provides **free BiDil** to eligible uninsured or underinsured patients facing financial hardship. ## About BiDil **BiDil** combines two drugs: **isosorbide dinitrate** (a nitrate that relaxes blood vessels) and **hydralazine** (a vasodilator that widens arteries). Together, they reduce the heart's workload, improve pumping efficiency, and ease symptoms like shortness of breath, fatigue, and swelling in ankles or legs[3]. It's taken **3 times daily** with meals to minimize headaches, a common side effect. Always follow your doctor's dosing instructions. BiDil is **uniquely indicated** for self-identified Black patients with heart failure, as clinical trials showed **43% reduction in mortality** compared to placebo[3]. ## Who Qualifies for the Program? The Arbor Pharmaceuticals PAP helps U.S. residents who: - Are **uninsured or underinsured**. - Have a **valid prescription** for BiDil from a licensed U.S. healthcare provider. - Meet **financial need criteria** (proof of income required; specific limits not publicly detailed). - Have a **medically appropriate condition** (heart failure). **Medicare Part D patients** may qualify if **denied coverage** or **ineligible for Low-Income Subsidy (LIS)**[3]. Medicaid patients should check separate guidelines. **Reauthorization** is required periodically to confirm ongoing eligibility[3]. ## Income Eligibility Arbor does not publicly list exact **Federal Poverty Level (FPL)** thresholds or household size limits. Applications require **proof of income** (e.g., tax returns, pay stubs, W-2s), and eligibility is determined case-by-case[3]. Contact the program at **(888) 417-7153** for personalized guidance. | Household Size | Estimated Threshold | Notes | |---------------|---------------------|-------| | Individual | Not specified | Proof of income required | | Couple | Not specified | Total annual household income reviewed | | Family of 3 | Not specified | Case-by-case evaluation | | Family of 4+ | Not specified | Call for details | *Table based on program notes; thresholds may align with 300-400% FPL common in similar PAPs, but verify directly[3].* ## Insurance Requirements - **Uninsured patients**: Fully eligible if other criteria met. - **Underinsured**: Eligible if insurance denies BiDil coverage (attach **denial letter**). - **Medicare Part D**: Eligible post-denial or if not qualifying for LIS. - **Private insurance**: Must show medication not covered or unaffordable copays. - **Medicaid**: Separate application may apply; confirm with program. Do **not** apply if you have adequate coverage for BiDil[3]. ## Step-by-Step Application Process Arbor offers **multiple application methods**: phone, fax, or mail.
