I had a surgery for occipital meningioma 15 years ago. I was prescribed 200 mg Zeptol CR tad. Due periodic occurence of seizure, Dr gradually incresed it to 400 mg in the morning and 600 mg in the night to control occurence of seizure. I would like to know what are the side effects of 1000 mg of this medicine per day. I am 73 yrs of age and otherwise lead a normal life. How should I minimise the side effects if any.
