I Have Insurance Through an Employer or Private Individual Policy and Am Not Covered by Medicare


About 79% of VIMPAT prescriptions cost patients between $0-$100 per month; for the remaining 21% of prescriptions, the most common cost is $150 per month.3

What you pay for VIMPAT will depend on your insurance plan. Each plan has different preferred drug lists and out-of-pocket amounts, and most include an annual deductible. If you haven’t met your deductible, you’ll see higher prices until the deductible is met; then your out-of-pocket cost will likely drop.

With the VIMPAT Savings Card, a one-month supply of VIMPAT can cost as little as $20. Learn more about the VIMPAT Savings Card.
