The table below shows what you may pay for different doses, forms, and quantities of Vimpat with a GoodRx coupon.
Formulation | Dose | Price with a GoodRx coupon |
|---|---|---|
60 tablets of Vimpat (brand-name) | 50 mg | |
60 tablets of Vimpat (brand-name) | 100 mg | |

Click “Find the lowest prices” or press “Enter.”
Have the coupon sent by text or email, or print it out.
To apply the discount, show the coupon at the pharmacy when you fill your prescription. Ideally, this is done at drop-off before the prescription is filled.
2. Check if you qualify for Vimpat’s Direct-to-Patient Program
If you have a prescription for Vimpat tablets, you may be eligible for the Vimpat direct-to-patient program. This program offers brand-name Vimpat for as little as $84.99 for 60 tablets if you meet eligibility criteria. If you order 180 or more tablets at once, you could pay as little as $79.99 per 60 tablets.
Some of the conditions for participating include:
You must have a valid prescription for Vimpat tablets that aligns with FDA-approved uses.
You must be a U.S. resident, including U.S. territories.
You cannot submit claims for reimbursement to any insurance plan, including Medicare or Medicaid.
The program operates outside third-party insurance and cannot be combined with other savings offers.
3. Ask about the generic version of Vimpat
The generic version typically costs much less than brand-name Vimpat, whether you’re paying out of pocket or using insurance. For example, 60 tablets of Vimpat 100 mg cost an average of $1351.78, while the generic version costs about $1004.70. Since generic medications work the same way as brand-name prescriptions, switching to generic Vimpat could be a simple way to lower your medication costs.
4. Request a larger supply
Getting a 90-day supply of Vimpat instead of refilling your prescription each month could help you save money. Some insurance plans — including those that use mail-order or specialty pharmacies — offer lower copays or discounts for 3-month prescriptions. Check with your insurance provider to see if this option is available. If it is, ask a healthcare professional if they can prescribe you a 90-day supply to help reduce your out-of-pocket costs.
5. Consider a lower-cost alternative
In addition to Vimpat, there are other antiepileptic (anti-seizure) medications that can help treat partial-onset seizures, and they may cost less. Talk to your prescriber about lower-cost alternatives that may be a good option for you.
6. Use your insurance’s preferred specialty pharmacy
If your insurance requires you to get Vimpat through a specialty pharmacy, make sure to use one in your plan’s network. This can help reduce your out-of-pocket expenses.
Using a preferred specialty pharmacy may also come with added benefits, such as lower copays, help with refills, and access to financial assistance programs. To find out which pharmacies are covered under your plan, contact your insurance provider or check your plan documents.
7. Use your tax-advantaged health account to pay for Vimpat
If you have a health savings account (HSA) or a flexible spending account (FSA), you can use those pretax funds to pay for prescription medications like Vimpat. HSA funds never expire, so you can always use the money in your account to cover qualified medical expenses. But FSA funds typically expire at the end of the plan year unless your employer offers a carryover option or grace period.
The bottom line
Without insurance, 60 tablets of brand-name Vimpat (lacosamide) 100 mg can cost $1351.78 on average. What you pay will depend on factors like your pharmacy, medication form, and insurance coverage.
If you qualify for Vimpat’s direct-to-patient program, you could pay as little as $84.99 for 60 Vimpat tablets or $79.99 per 60 tablets if you order 180 or more tablets at once. Other ways to save include using a GoodRx coupon, asking about the generic version, or using tax-advantaged health accounts to help cover out-of-pocket costs.
Why trust our experts?
Methodology
We obtained national prescription coverage data for each medication from Managed Markets Insight & Technology (MMIT). The data reflects health insurance coverage as of June 2025.
We calculated the percentage of enrollees in plans that cover each medication by dividing the number of enrollees covered for the medication within a specific insurance channel (e.g., ACA, Medicare, Medicaid) by the total number of enrollees in all plans within that channel.
We determined the percentage of enrollees in plans with a prior authorization requirement by calculating the proportion of enrollees in plans that required prior authorization for the medication within each channel.
Finally, we measured the percentage of enrollees in plans with a step therapy requirement by calculating the proportion of enrollees in plans that imposed step therapy requirements for the medication in each channel.
These estimates, derived from national MMIT coverage data, provide insight into health insurance coverage for each medication. They take into account restrictions such as prior authorization, step therapy, and quantity limits. The percentages are expressed relative to the total number of enrollees covered by various insurance channels, including ACA plans, commercial (excluding ACA) plans, Medicare, and Medicaid (both state-run and managed care plans).
