I was on put on Zyprexa a while ago it made me gain almost 30 lbs so we are weaning me off the olanzapine/generic of Zyprexa. I am now taking invega/palperidone(generic of invega). Has anyone ever taken this? How was the weight gain? What kind of side effects did you have? I wish I was on another drug because I am not losing any weight yet. Any information on invega/palperidone is appreciated.
