Oxcarbazepine
"I took Trileptal from Feb 2015 to Dec 2015 - now weaning off it to lithium. I LOVED the way Trileptal handled my bipolar depression. I felt alert, alive, just really great. Unfortunately, a fall in August alerted my doctor to my bones being weakened. Also, I have optic neuritis in my left eye starting in July. Between those two side effects, we've decided to taper off the trileptal and return to lithium. I'm sad to stop it but the soft bones and eye issues are too great a problem to continue it."
