Generic Keppra Side Effects

After paying $400 - $450 per month for several years for brand name keppra, I decided to try generic (again). I tried generic before and did not like how it made me feel. I have been on generic for one week and the following has appeared:

  • Extremed tiredness
  • Runny nose
  • Sleeping issues
  • Weird dreams
  • Body aches

I called my neurology doctor this morning and the nurse practioner called back to say that those items are not side effects to generic keppra and that I should contact my regular doctor. However, what I have read online - many of those symptoms are side effects. I was wondering how long does it take for side effects to start disappearing before I make a decision to go back to brand name.
