Seizure Prevention
"After taking Dilantin, (and keppra which cause depresion) it keep me and mom extremely extremely cool. depression faded away. It does well with seizures unless I miss a dose.Now I ONLY have nocturnal seizures. Side effects got worst.I have double vision, studdering, Alzhimers type memory,  Cant walk at all dizzinyness, and rashes Other than seizures, side affects are MUCH worst  then the medicine itself. I encourage you NOT to take it at all. AT ALL"
