About This Medication

# Harrow Patient Assistance Program Guide: How to Get Natacyn (natamycin) at Low or No Cost Natacyn (natamycin ophthalmic suspension 5%) is a prescription antifungal eye drop used to treat fungal infections of the eye, such as blepharitis, conjunctivitis, and keratitis. This patient-friendly guide explains how to access financial assistance from Harrow, the manufacturer, or other resources to get Natacyn at low or no cost, especially if you are uninsured, underinsured, or facing financial hardship.[1][2] ## About Natacyn **Natacyn** is the brand name for natamycin ophthalmic suspension 5%, a topical antifungal medication specifically indicated for fungal eye infections. It works by stopping the growth of fungi that cause conditions like fungal keratitis (corneal infection), blepharitis (eyelid inflammation), and conjunctivitis (pink eye caused by fungus). These infections are rare but serious, often linked to contact lens use, trauma, or weakened immunity, and require prompt treatment to prevent vision loss.[1] **Key facts about using Natacyn:** - Apply 1 drop in the affected eye every 1-2 hours initially, then taper as directed by your doctor. - For topical ophthalmic use only—not for injection. - If no improvement after 7-10 days, your doctor may test for other causes.[1] - **Contraindications:** Avoid if allergic to natamycin or its components. - **Precautions:** Use caution in pregnancy, nursing, or pediatrics (safety not fully established).[1] Natacyn has no generic equivalent, making it expensive—often $1,000+ per bottle without insurance. That's where patient assistance comes in.[3][7] ## Who Qualifies for Assistance? Harrow, the current manufacturer of Natacyn (previously under Santen and associated with Alcon programs), offers support for eligible patients. While specific details like income thresholds are not publicly listed on their site, manufacturer patient assistance programs (PAPs) typically target:[2][4][7][8] - Uninsured or underinsured U.S. residents. - Those experiencing financial hardship. - Patients without adequate prescription coverage. Contact Harrow at **1-833-4HARROW (1-833-442-7769)** for product inquiries, customer service, and PAP eligibility. They may provide Natacyn at no cost to qualified patients, similar to other eye medication programs.[2] Third-party advocates like AdvocateMyMeds (1-888-233-4303) or databases such as NeedyMeds, RxAssist, and RxHope can help navigate applications.[5][7] ## Income Eligibility Breakdown Exact income limits for Harrow's program are not specified online and vary; call to confirm. General PAP guidelines often follow **400% of the Federal Poverty Level (FPL)** or similar. As of 2026, here's a typical breakdown for illustration (always verify with Harrow): | Household Size | Annual Income Limit (approx. 400% FPL) | Notes | |---------------|---------------------------------------|-------| | Individual | $60,000 | Uninsured/underinsured priority[7] | | Couple | $80,000 | Financial hardship assessed | | Family of 3 | $100,000 | U.S. residents only | | Family of 4 | $120,000 | May adjust for higher families | **Notes:** Eligibility often requires proof of income, residency, and lack of coverage. Programs like Alcon Cares™ (legacy) provided free meds for similar eye drugs to those with limited insurance.[8] ## Insurance Requirements Harrow assistance is primarily for **uninsured or underinsured** patients. If you have insurance:[3][4][7] - Natacyn is often **Tier 4/specialty** on Medicare Part D (high copay, $50-$150+).[3] - Most plans require **prior authorization (PA)**—your doctor submits this.[7] - **Medicare patients:** No specific Harrow copay card noted; check GoodRx for discounts (cannot combine with insurance).[3][6] - In-office dispensing may use **medical benefit** for better coverage.[7] - If insured but high-deductible, cash discounts (e.g., WellRx, GoodRx) might be cheaper—save up to 80%.[6][7] ## Step-by-Step Application Process 1. **Confirm need:** Discuss with your ophthalmologist; get a prescription.[1] 2. **Call Harrow:** Dial **1-833-442-7769** to inquire about PAP. Ask for application forms.[2] 3. **Gather documents:** Typically include proof of income (tax return, pay stubs), prescription, ID, and insurance denial (if applicable).[5][7] 4. **Submit application:** By mail, fax, or online (details from call).
