hi i was rushed in hospital yesterday night after having 4 epilepsy attacks. i have gone off eplim as it is very dangerous during pregnancy. doctors was meant to put me on new medication that will be safe during pregnancy. but the nurse says all medication is dangerous and can cause miscarriages. stillborn etc. but hospital told me last night it is safe and they give me clobazam for my epilepsy attacks and Gad ( Generalized Anxiety Disorder). now i dont know who to believe is it really safe to take or not. will i have a allergic reaction to it like the rest of the medication
