I have been on geodon fir the past 5 years and have also had side effects like your daughter its like i can't talk right. I have experienced other side effects as well such as pain in the chest like someone is squeezing your heart, and chest pain that comes suddenly and hurts for a second then goes away. Other side effects are twitching of your hands and shakiness of your hands. I have tried talking to my doctor to change the medication but she will not. So I would check wiith your daughters doctor as well so she doesn't have the speech problem
