Epilepsy Home > Generic Peganone

Although all of the patents for Peganone (ethotoin) have expired, no generic versions of this medication are available. Because this is an older medication that has to be taken several times a day, the demand for this product may be too small to make it profitable for a company to make a generic Peganone medicine.

Can I Buy Generic Peganone?

Peganone® (ethotoin) is a prescription medication used to treat certain types of epilepsy. Specifically, this medicine is approved to treat the following conditions:
Peganone is an older medication that is not used much anymore. This is because it has been largely replaced by similar medications that do not have to be taken as frequently as Peganone.
Peganone is made by Abbott Laboratories for Lundbeck, Inc. Although the patents for Peganone have long expired, there are no generic versions available.

When Will a Generic Version Be Available?

It is impossible to predict when, or even if, a generic version of Peganone might become available. Most likely, no generic versions are available because the demand for this medication is too small to make it profitable for a manufacturer to produce a generic version.

Is Ethotoin a Generic Peganone?

No -- ethotoin is the active ingredient in Peganone, but is not a generic version of it. What can be confusing is that the active ingredient of a drug is often referred to as the "generic name."
The generic name is different from a generic version of a medicine. In order for there to be a generic version, the original medicine must have gone off-patent (which has already occurred for Peganone) and another company besides the original manufacturer must make the product (which has not happened for Peganone).
