My Sister Is 30 Years Old. She Had A Fit

My sister is 30 years old. She had a fit two times within two months at the age of 25, few month after the accidental death of her father. Brain CT scan report shows small traces of dust like something. After which she started taking Zeptol CR 200, twice a day morning & night. She continued up to few months then stopped without Dr concent so few month after stopping she suffered by a fit (third time). Then as per Dr advice she is taking same tablet from last five year & never had a fit. But As per Dr advice she stopped taking zeptol CR 200 from last one month may be due to which she had a fit stroke yesterday night. Please tell us what to do & for how long need to take zeptol CR 200. Also tell us about its side effect if any?. Can we take ayurvedic treatment with zeptol?
