Zonegran from the people I've heard from take it as an adjunctive medication for Focal Epilepsy. Most of whom report many of the seizure meds typical side effects. Zonegran does have many potential side effects like all other Anticonvulsants. That's not to say all people on it will have those effects. I have been on these types of meds for over 50 years for seizures. Believe me there is no one super drug without side effects for it's main use of seizures or Neuropathy. I was the Antoconvulsant Dilantin for over 20 years and didn't notice any significant side effects until a few years later when the Neuropathy started. So even if side effects aren't noticed that doesn't mean they are not causing damage.
Take care & remember if it sounds too good to be true it most likely is.
