Viatris Patient Assistance Program Patient Guide: How to Get Dilantin (Phenytoin) at Low or No Cost

About This Program

The Viatris Patient Assistance Program (PAP) is a free medication program designed to help uninsured and underinsured patients access essential medications, including Dilantin (phenytoin), at no cost. Dilantin is an anticonvulsant medication used to prevent and control seizures. If you struggle to afford your prescription medications, this program may be able to help you receive your medication directly from Viatris at no charge.

Who Qualifies for This Program

To be eligible for the Viatris Patient Assistance Program, you must meet all of the following requirements[2][3]:

  • U.S. Residency: You must be a current United States resident (this includes U.S. Territories)

  • Valid Prescription: Your medication must be prescribed by a licensed U.S. healthcare professional for an FDA-approved indication
  • Financial Need: You must demonstrate financial need based on program criteria

Each applicant is individually assessed for eligibility based on the information provided in the application[2][3].

Income Eligibility

While specific income thresholds are not publicly detailed in available program materials, the program uses a needs-based assessment to determine eligibility. The program evaluates your individual financial situation as part of the application review process. When you apply, you will need to provide information about your household income and financial circumstances so the program can assess whether you qualify based on demonstrated financial need[2][3].
