Some people are on the same meds whether they have Bipolar or schizophrenia, others are not. It depends on the persons symptoms and the dr. It can be trial and error. What works for one person may not work for another. There is no magic or perfect pill. Her dr knows best and you must have faith in the dr you choose. I understand they are far away from you so when you do have an appt for your sister have your questions written down for the dr and hopefully you will get the answers you are needing. If you are able look on the Internet for information on Bipolar and information on Schizophrenia. This should give you a lot of details you are looking for. Our site her at MedHelp also has a Schizophrenia forum that you may find helpful. I wish you and your sister the best.
