seizures
"Effective prevention of seizures, but I only had two episodes 16 months apart started at age 57.  Started at 25mg twice a day, increased to 50mg.  Was prescribed to go up to 100mg but requested to stay on the 50mg as I had no episodes and didn't like the effect it had on me.  I am now used to it but it makes me drowsy.
Big downside is I have just found out that I have osteoporosis and it appears that zonegran is contributing to accelerated leeching of my bones.  Will be discussing with neurologist in a couple of weeks."
