Brief Answer:
Treatment is continued for at least two years.

Detailed Answer:
I read your question and I understand your concern.

It is hard to exactly predict how individual patients will respond to treatment. In the elderly like yourself, particular care is necessary because the consequence of a fall from a seizure could be more serious than in the young, due to the greater likelihood of fractures or other traumatic injuries.

Generally speaking if a diagnosis of epilepsy has been confirmed treatment is continued for at least two years even in the complete absence of seizures. If the patient is seizure free after two years treatment interruption should be carefully considered based on factors such as epileptiform activity on control EEG, the presence of an focal brain lesion on brain imaging like stroke or tumor with augmented risk of seizure, the side effect tolerance of the given treatment possible risks due to seizure recurrence (such as falls which I mentioned). There is no decision with a 100% outcome certainty, it's about weighing the risks and benefits and making the lowest risk decision.

So you should continue your treatment for at least two years from your last seizure. If seizure free in two years time you should discuss with your doctors the abovementioned factors in order to take a decision on further continuation.

I hope to have been of help.
