Thanks for writing in.
Since its been more than 4 months of prophylactic eptoin
for an episode of brief unconsciousness
, you can definitely start weaning the dosage slowly. Say for next 2 weeks take twice a day, see whether you have any new symptoms coming up, then say once a day for next 2-4 weeks if you are fine.
But it is always advisable to stop eptoin after consulting a neuro-physician, who might need to examine you and may be a EEG or repeat CT to rule out other possibilities.
Get well soon,
