Generic Zonegran

Now that all the patents for the medication have expired, generic Zonegran is currently available. It comes in three strengths and is made by several different manufacturers. When considering whether to switch from your current seizure medication to generic Zonegran, keep in mind that even small changes in medication can cause problems, so it's best to stick with a medication that you are stable on.

Is Generic Zonisamide as Good as Zonegran?

All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generic versions are equivalent to the brand-name medications and assigns a rating to each one. An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic zonisamide versions currently available have an "AB" rating, meaning they should be equivalent to Zonegran.
 
However, generic medications are allowed to have different inactive ingredients from the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with certain allergies or sensitivities. In addition, many healthcare providers feel that switching between different brands of Zonegran or zonisamide is not a good idea. Even small changes in a seizure medication can cause problems. If you are stable on a particular brand of Zonegran or zonisamide, it is best for you to stay on that brand, if possible. If you must switch brands, your healthcare provider may want to monitor you more closely for a while.
