Unfortunately that is how these meds work, some counteract the effectiveness of others. As long as it balances out, but honestly not even the top neuro in the country knows it all.

Thanks for all the responses...my Keppra was upped again to 3250mgs a day. Hopefully this helps.

Keppra 2000mg in the Am 2000mg pm Doctor added 250mg a day

I take 2000 mg in the morning and 2000mg at night of Keppra

I am taking 3000 mg daily and it has helped. I am having a lot less seizures. I am so thankful.
