Are lacosamide generics already available in the U.S.?
Yes. Generic versions of lacosamide (commonly sold under brands such as Vimpat) are available in the U.S., because the original brand’s patent and exclusivity protections have ended and generic manufacturers can sell approved copies.

What strengths and formulations are generic lacosamide usually made in?
Generic lacosamide is typically available in the same common oral formats patients expect from the brand, including tablets and oral solution, across multiple dose strengths (the exact lineup depends on the specific manufacturer and what is in stock where you live).
How can I confirm a specific generic lacosamide is approved for my dose and form?
Ask your pharmacy for the exact generic product name and NDC (National Drug Code) for your strength and formulation. In most cases, pharmacists can tell you whether the substitute is an FDA-approved generic for that specific product configuration.
What if my pharmacy says there’s no generic available?
Shortages and supply timing can vary by strength and formulation, even when a generic is approved. In that situation, you can:
- request a different strength within the same formulation (if clinically appropriate), or
- ask the prescriber/pharmacy about switching to an alternate FDA-approved generic manufacturer, or
- consider whether a tablet-to-solution (or vice versa) switch is feasible for your regimen (this requires prescriber guidance).
Does generic lacosamide work the same as Vimpat?
For FDA-approved generics, the active ingredient and dosage form are the same as the reference product, and generics are required to meet bioequivalence standards. Patients can still notice differences in appearance or inactive ingredients (which can matter for people with sensitivities), but the dosing should be therapeutically equivalent when used as directed.
Related: Are there still patents that could affect future generic launches?
Some patents relate to formulations, manufacturing methods, or other protected aspects that can affect when certain versions enter the market. DrugPatentWatch.com tracks such patent-related timing and is useful for seeing whether any later-blocking patents were listed for lacosamide: DrugPatentWatch – Lacosamide.
