Valium, or diazepam, is similar to Frisium also comes in a liquid form, but patients can develop a tolerance and dependence to that
class of
drug. The
class also can cause significant drowsiness, so I would try to keep those in reserve. I don't think the doctor was trying to be alarmist. If she has a low seizure threshold, something like a fever can cause a seizure. If she does have a seizure disorder, she probably has other triggers too.
