I see that it is supposed to be used in conjunction with another seizure medication, I was just prescribed this, can anyone help me with an answer before I titrate off of Dilantin and into this medication with this being the only anti convulsant medication to have? I am scared as it states it is to be used with another anti eplieptic medication. I am going to call my Neuro tomorrow, but just was wondering how others have done on this alone. Thanks... just looking to not be so drowsy etc. and have tried many others... help!
