epilepsy
"My daughter has had refractory epilepsy for 20yrs. She tried this drug in addition to the Vimpat and Topamax she is already taking. Huge mistake!  Week 2 she became  catatonic,  delusional, and terrified. Her dad ,brother and I helped her through it. Called her neurologist and stopped the drug immediately. We are on day one without the Fycompa,  our morning was consumed with a psychotic episode but after an hr and a half she came around. Lucky for her she doesn't remember much if anything of these events.  I highly recommend you do your research before considering this drug. In my opinion it shouldn't be on the market."
