<s>[INST] Hi Doctor, My sister is 23 years old and she had epilepsy attack about a two years ago. It was the first time she had that attack. We went to doctor and he suggest us to give her some medicine. First our doctor said that she has to take these medicines for only a year but it s now about three years since she is taking those medicines. Which are: LEVACETAM ( LEVETIRACETAM - USP 500 and ENCORATE CHRONO -500 twice a day) I was worried about the side effect of these medicines. What is the max time she need to have these medicines ? [/INST] Hi,first seizure episode does not need any medicine.In your case antiepileptics should not be started because you had only one seizure.So you can stop medicines.If you have the second episode then only start the medicine.Thanks </s>
