My son has been taking Keppra since his first seizure last year when he was 18, starting out with 500g. He kept having the seizures (all grand mal) off and on and because he was planning on going into the military, he was told that because of the seizure disorder, he could not serve. Given a medical discharge and coming home, he still had them, but the cause was because at times he forgot to take his meds or he worked out over exerting himself, stuff like that. From the end of April until July 6th, he did not have a seizure (his Keppra was increased to 3000g a day), and that seizure was not as bad as the previous ones he had. We ended up switching doctors because the original doc did not want to do an eeg on my son, so with my husband and my decision plus our primary care physician agreeing, we starting having my son see a new doc. This doc seems to really care about his patients, and after talking with us, he gave my son a prescription for Depakote, 500mg three times a day along with the Keppra. A day and a half after taking the drug (the first day he took it at night then taking it as prescribed daily), he started vomiting. He would eat, later on lay down, wake up EXTREMELY nauseous, and start throwing up. This happened for four and a half days, and the doctor told him to stop taking the meds immediately. He did blood work again and said that his Depakote serum levels had dropped drastically and he wanted to put my son back on the Depakote, but at half strength; 250mg three times a day. Our answer to that? HELL NO!!! My son was miserable; he has a job and hangs out with his friends and not being sure if he would start throwing up again, he minimized going out except to go to work. It is frustrating as all HELL, took that crap for six days and four and a half of those days he was vomiting, unsteady on his feet, eyes were red looking like he was a zombie, and had starting messing with his memory in ONLY SIX DAYS! Yes we all want him to be free from this demon, and so far for these past few months of this year, (from end of April to July 6) he has had one seizure. He has not had another one since that day. As far as we are concerned as his parents, he will never take that crap again, I don't care WHAT this doctor says. And I am going to say that I believe that my son will not want to take it again either, even at a lower dose. I took the time to call the company who manufactures the Depakote, and one of the reps I spoke to said that even if my son took a lower dose, it could still have the effects of vomiting as with the higher dose, and her concern is that when he is throwing up, he is also throwing up the Keppra which could cause him to have a seizure. NOBODY wants that!
