I am over 4 months pregnant, and I got diagnosed with Epilepsy on Valentines Day, and my doctor put me on Topamax 25 mg. to start off with. I was not having seizures that often, but now it is everyday.I feel comatose all the time, and the hot Flashes are so bad they will send me into a seizure. Also the nausea is horrible, and it says on the label not to take with antihistimines. Well Dramamine and Phenergan both are antihistimines. My doctor keeps assuring me that this is the drug for me. Pray for Me
