My Stepfather Is Schitzo-active And Has Impulse Control Disorder. Hes

My Stepfather is schitzo-active and has impulse control disorder. hes been with his therapist for over 17 years. he took him off his medicine in 2014 and we didnt know what was going on until it got really bad sobwe had to 302 him. He was on 3mg Respersal after leaving the hospital and barely after 6 or 7 months he reduced him down to 2mg--right off the bat-because he is prescribed testosterone due to the medicine hammering it and his doctor not agreeing with him taking it. at first things werent too bad, but as time as gone along weve noticed anger, edgyness and some odd behavior that just seemed to get worse. he had a meeting last month with his psyc and therapist because he was not acting himself and were going to drop him from the program but his psyc refused to up his med back to 3mg. he told him to "be a bit nervous" ever since then he hasnt been himself, first it seemed he was just depressed and tired. but now hes displaying odd symptoms like he did 2 years ago. saying bizaree things, hes completely detached himself from everyone, doesnt talk or eat much, and has been showing signs of impulses. what do we do?
