Hi Cyndie,
Watch her teeth and make sure she drinks alot of water.. I was not told till later about the damage it does to your teeth it makes them thin. SO make sure she brushes often trust me she doesn't want to lose her teeth. Why the water? because dilantin affects the kidneys so she wants to flush her system out often. That I was told about so I was lucky on that

as long as she takes good care of herself she will be fine on it. I never had alot of problems on it
