# Pfizer RxPathways Patient Guide: How to Get Zarontin (Ethosuximide) at Low or No Cost ## About This Program The Pfizer RxPathways program is designed to help eligible patients access their prescribed Pfizer medications, including Zarontin (ethosuximide), at reduced or no cost. Pfizer has provided over 2.8 million prescriptions through this program, with 44,000 patients receiving free or discounted medications in 2024 alone. This guide will walk you through the entire process of applying for assistance with Zarontin. ## What is Zarontin (Ethosuximide)? Zarontin is a prescription medication manufactured by Pfizer used to treat absence seizures (petit mal seizures). Like all medications, access to Zarontin can be challenging for patients facing financial hardship. The Pfizer RxPathways program exists to bridge this gap and ensure that cost is not a barrier to receiving your prescribed treatment. ## Who Qualifies for This Program? To be eligible for the Pfizer RxPathways program for Zarontin, you must meet the following criteria: **Insurance Status:** You must be uninsured or underinsured. Patients with commercial insurance (including insurance through an employer or Federal Employer Plan) are not eligible for the free medication program, though other assistance options may be available to you. **Income Requirements:** You must meet income eligibility criteria based on your household size and income level. While specific income thresholds are not publicly detailed, the program uses a sliding scale based on federal poverty guidelines. The program considers your household size and total annual income when determining eligibility. **Prescription Requirement:** You must have a valid prescription for Zarontin from a licensed healthcare provider. ### Income Eligibility Overview While exact thresholds vary, the program generally serves patients with limited financial resources. For specific income eligibility information tailored to your household size, you should contact a Pfizer Medicine Access Counselor directly. | Household Size | General Eligibility Range | |---|---| | 1 person | Contact program for details | | 2 people | Contact program for details | | 3 people | Contact program for details | | 4+ people | Contact program for details | *Note: Exact thresholds are determined on a case-by-case basis.
