Is there a generic version of lamotrigine?

There are several generic versions of lamotrigine available in the United States, produced by at least five different companies. They include regular and chewable tablets, but there is no generic version of the orally disintegrating tablets yet. All currently available generics have received an AB rating from the United States Food and Drug Administration, which means that they are considered equivalent to Lamictal, the brand name version of lamotrigine.

However, the inactive ingredients in generic versions often differ from those found in Lamictal. This is why someone can be allergic to one form of lamotrigine, but not another. As well, there is concern by some doctors that not all forms are exactly equal in their effectiveness, and there was even a study from Canada that noted some people had more seizures when they switched from Lamictal to a generic. Therefore, if you switch from Lamictal to a generic version, or if you change from one form of generic to another, if would be prudent to let your doctor know.
