When Will There Be a Generic Lisdexamfetamine?
The first patent for lisdexamfetamine currently expires in June 2023. This is the earliest date that a generic version of lisdexamfetamine could become available. However, there are other circumstances that could come up to extend the exclusivity period of lisdexamfetamine beyond 2023. This could include things such as other patents for specific lisdexamfetamine uses or lawsuits. Once lisdexamfetamine goes off patent, there may be several companies that manufacture a generic lisdexamfetamine drug.
