Seizures
"I am so glad I found this forum!  My husband was on Dilantin and it was working well but a few years ago his Dr switched him to Keppra because it was newer.  He started having severe depression and mood swings to a point where they diagnosed him with Bipolar.  The depression has been getting worse and worse to a point where we almost hospitalized him because I was afraid he may hurt himself.  Today I spoke with his mental health provider and asked about trying Depakote and decided to come home and research if he could take both.  After reading the reviews I am 100% convinced that it is the Keppra causing his depression and I am taking him to the Dr Monday to have him put back on Dilantin!"
