My son is a paranoid schizophrenic who is 35 years old and lives alone.  He has had many hospitalizations for psychotic episodes and can become very violent.  He has been on many oral antipsychotics but he is noncomplient with them and eventually takes himself off them.  Because of this he has regressed many times.  He describes severe side effects of almost all medications.  Abilify was the most effectilve for him but he refused to continue on it.  He is currently on monthly injections of haldol with good effects relating to his psychotic  episodes .  However he sleeps alot,  has little interest in his surroundings, no ambition.  He does not clean his apartment and has very poor physical hygiene. 

My question is if there are any other injectable antipsychotics out there?
