Both Dilantin and generic phenytoin contain the same active ingredient, phenytoin, and are used to control seizures [1]. The U.S. Food and Drug Administration (FDA) requires that all generic drugs be as safe and effective as their brand-name counterparts. This means generic phenytoin works the same way and has the same risks and benefits as Dilantin [1]. The primary difference is typically cost, with generic versions often being more affordable [1].
When does the patent for Dilantin expire?
The original patents for Dilantin have long expired, allowing for the production of generic versions [2]. Drug patent information can be complex and can include multiple patents covering different aspects of a drug, such as formulation or method of use.

Are there any side effects associated with phenytoin?
