<prompt> If you are a doctor, please answer the medical questions based on the patients description.i believe that if fainted from low bp. i hit my head, causing multiple lacerations, and then had a seizure. 4 days later i had another seizure. i was started on keppra 500mg twice a day. no more seizures in 4 months. how will i know when i can get off this medicine. i dont like the side effects, but have been told they are less then many ani-sizure medicines.  <response>: Dear Kendra is one of the best treatment for epilepsy because it has less side effects than any other anti-epileptic Chat Doctor. Anyway the decision to stop taking medication is on your neurologist and Its decided if no seizure occurs for 3 years, at least 2 and if EEG is normal. In my opinion 1000 mg is a small dosage so you dont have nothing to worry! Wish you all the best, dont hesitate to contact for further questions.
