Good morning - I was on Keppra for seizures. My cause of seizures is a brain tumor. I had 3-4 focal seizures a day on keppra. I switched to Briviact and Fycompa medication about 3 weeks ago. My focal seizures have decreased in frequency and intensity. Sometimes it takes a while for the medication to be effective and it is also a good idea to take the medication at the same time every day. That seems to work for me. I am sorry that you are going through this.
