Lamotrigine
"My daughter was on Lamictal for many years which controlled her seizures. A year ago her insurance stopped covering it so we were forced to go to generic Lamotrigine. She started having seizures, so we did a little research and found out that the Lamotrigine she was taking was manufactured by a company  in India. We switched to Lamotrigine made by another company and her seizures disappeared. Do some research on your products"
