Divalproex sodium
epilepsy
"I was on this med in Europe before it was available here.  (35 years ago)  I was in the clinical trials in the US starting with Depakene and then moving to Depakote and Depakote ER.  At this point I can't really point out the side effects since I've been using it for so long. Being tired is probably one of them.  Also blurry eyesight occasionally.

It started out as an anti-convulsant and then was used for other things."
