Schizophrenia is such a hard thing to fight. It doesn't really surprise me that he is on so many meds. As long as he is taking and managing all of them it should me working a lot better.
Seroquil (sp) is what they put me on in my last hospital stay. It slows ya down a lot. Some of these drugs should not be taken all that regularly but for certain symptoms. Like this mofo. If you are his caretaker than you should find out on your own what each one does. Even find a different doctor and go to him with your questions, just as an informational thing. DO NOT insist on talking to your sons doctor--please from personal experience--lord I have to fight my mother on this almost every single day---you are there to help but as a third party. This is your son's battle and you can't fight it for him as much as you want to.
